PURPOSE: The quantitative objective of the current systematic review was to identify the potential role of urinary microbiota in bladder cancer (BC) carcinogenesis, invasiveness, progression, and metastasis. MATERIALS AND METHODS: The proposed systematic review was conducted in accordance with critical review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement, and the Joanna Briggs Institute (JBI) methodology for systematic reviews. The search strategy aimed to find both published and unpublished studies up to the January 2024. A JBI appraisal checklist was used to assess possible biases. RESULTS: This systematic review was centered on 27 studies comprising 926 BC patients. Overall, 412 control individuals were compared with BC patients. The most common sampling method was midstream urine collection. Regarding microbial alpha diversity, there was no statistically significant difference between cancerous and healthy samples (n = 8), recurrent and not recurrent (n = 1), responders versus non-responders(n = 1), tumor grades (n = 1), and collection methods (n = 1). However, five studies reported higher diversity in controls, and five other studies reported, conversely, high levels of alpha diversity in BC patients or recurrent cases. Furthermore, a responder (RE) to treatment and a non-muscle invasive bladder cancer (NMIBC) groups demonstrated significant difference with non-responder (NR) and muscle invasive bladder cancer (MIBC), respectively. In terms of beta-diversity, nine studies reported significant diversity between BC patients and controls, one article demonstrated difference between recurrent and not recurrent patients, a study reported significant difference in RE and NR groups whereas another showed opposite, and others (n = 4) did not find any difference between BC, controls, MIBC and NMIBC patients, or between tumor grades. One study reported a difference between the collection method and beta-diversity in males and another reported the difference in females. CONCLUSION: The included studies demonstrate that the composition of urinary microbiota is altered in patients with BC. However, the differentially enriched genera in the urine of these patients vary between studies, and there is too much heterogeneity across studies to make any reliable and valid conclusions. Furthermore, well-designed research is necessary to assess the role of microbiota in the carcinogenesis and progression of BC.

One of the most common cancers of the urinary tract is bladder tumors. Bladder cancers are divided into two groups: non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer. (1) Trans-Peritoneal Radical Cystectomy (RC) with pelvic lymphadenectomy is the standard technique in muscle invasive and high risk non-muscle invasive bladder cancer (2). and Urologist around the world are more familiar with trans-peritoneal technique. In some articles extra-peritoneal Radical Cystectomy (RC) implied as an decreased postoperative complications techniques. In this letter we want to compare these two techniques and find out the pros and cons of these techniques.

PURPOSE: From a diagnostic standpoint, certain approaches to genetic screening in clinical practice remain ambiguous in the era of assisted reproduction. Even the most current guidelines do not provide definite guidance on testing protocols, leaving clinicians to carefully determine which tests best serve patients struggling with infertility. The lack of uniformity in the current practice of male fertility evaluation can prove to be quite costly, thus necessitating healthcare practitioners to carefully appraise the necessity and weigh the advantages against potential economic and psychological detriments. The objective of this review is to map the existing literature on the general topic of the clinical indications of routine karyotyping and/or AZF screening in infertile men, identify key concepts, determine where the gaps are, and lastly, provide an overview of the conclusions drawn from a body of knowledge that varies widely in terms of methodologies or disciplines. MATERIALS AND METHODS: A thorough search was conducted for the published findings up until July 2023, utilizing PubMed (MEDLINE). This comprehensive search involved the use of specific search keywords, either individually or in combination. The search terms employed were as follows: "Karyotype", "Klinefelter" or "KS" or "47,XXY", "AZF" or "Azoospermi*" and/or "microdeletion*" in the title or abstract. Once the titles and abstracts of selected articles were obtained, the complete texts of linked papers were meticulously scrutinized. RESULTS: A total of 191 records were identified from PubMed. During screening, 161 records (84.3%) were eliminated. Finally, 30 papers were included in this scoping review, which was conducted in 18 countries. The number of sequence tag sites (STSs) used in the studies varied from 5 to 59. The rate of AZF deletions among patients with NOA ranged from 1.3% to 53%. The mean frequency was estimated to be 5.6%. The rate of YCM among patients with XXY karyotype was nil in 19 out of 30 studies (63%), whilst, in the remaining studies, the rate varied from 0.8% to 67%. CONCLUSION: This review provides insights into managing male infertility. The presence of spermatozoa in ejaculation and successful surgical retrieval cannot be excluded for individuals with AZFb/AZFbc microdeletions. Screening for Y chromosome microdeletions is not needed for mosaic or classic KS. Only 1% of individuals with sperm concentration exceeding 1×106 sperm/mL and less than 5×106 sperm/mL exhibit AZF microdeletions; therefore, testing referral for such populations may need reassessment. Individuals with mosaic monosomy X karyotype and certain chromosomal anomalies should be referred for AZF deletion screening. These findings have implications for male infertility management and future research.

PURPOSE: We aimed to evaluate the diagnostic sensitivity and specificity of the miRNA-371a-3p for the primary diagnosis of germ cell tumors (GCT) and to investigate its relationship with pathological factors and clinical stage in the Turkish population. MATERIALS AND METHODS: In this prospective study, a total of 60 patients with GCTs, and 40 healthy male controls were examined for serum levels of miRNA-371a-3p before orchiectomy and again two weeks after surgery. The miRNA-371a-3p, alpha-fetoprotein (AFP), and beta-human chorionic gonadotropin (bHCG) levels in the preoperative and postoperative periods were compared at different clinical stages. Receiver operating characteristics curve analyses were performed to determine the sensitivity and specificity of miRNA-371a-3p. Clinical and pathological factors such as clinical stage (CS), tumor size, histology, rete testis invasion, and lymphovascular invasion, potentially impacting miRNA-371a-3p expression levels (relative quantity, RQ), were evaluated statistically. RESULTS: The sensitivity of miR-371a-3p in GCT patients was 98.3%, and the specificity was 95% (AUC = 0.997 [95%Cl:0.99-1], p < .001). miR-371a-3p expression was not detected in two patients with teratoma. The median miR-371a-3p RQ was 489 times in GCT and 2.2 times in the Control group (p < .001). In the postoperative period, there was a significant decrease in AFP and bHCG levels in all CS-1 (p = .01) and 30% of the other CS (p = .3). Throughout this time there was a decrease of 19 times at the miR-371a-3p RQ in CS-1(p < .001) and 1.6 times in the other CS (p < .001). The miR-371a-3p RQs were correlated with tumor size and CS. CONCLUSION: The miR-371a-3p seems to have higher diagnostic accuracy than classical serum tumor markers in GCT.

PURPOSE: To compare 90-day perioperative complications and pathological outcomes between laparoscopic radical cystectomy (LRC) and extraperitoneal radical cystectomy (EORC) approaches. MATERIALS AND METHODS: All operations were performed in a single high-volume tertiary referee center by the same surgical team.Males ≥ 18 years with pre-cystectomy clinical T1-T3 disease and having undergone an ileal conduit were included. Exclusion criteria included patients with inflammatory bowel disease, previous pelvic and/or abdominal irradiation, neo-adjuvant chemotherapy, and/or clinical T4 disease. Perioperative outcomes such as operative time, estimated blood loss, transfusion rate, hospital stay, and 90-day complications were evaluated. The recovery duration of regular bowel activity, mean stool passage,and ileus rates were recorded. RESULTS: A total of 221 patients met the inclusion criteria(81 LRC and 130 EORC). Demographics and preoperative parameters were comparable. Intraoperative estimated blood lossfavored LRC by a median of 450 mL (200-900) P=.021) vs. a median of 700 mL (300-2900) for EORC. The transfusion rate did not differ between the two groups; %14.8 (N=12) for the LRC and %20.8 (N=27) for EORC (P=.37). The median hospital stay was 9 (4-49) days for EORC and 8 (4-29) days for LRC (P=.011). The need for analgesics to control pain through an epidural catheter was higher for EORC (P=.042). There was no difference in overall complication rates (P=.47). CONCLUSION: Although LRC appears to have a slight advantage over EORC, both techniques yield satisfactory results in regard to ileus rates and 90-day perioperative complications.

PURPOSE: To establish a prediction model for repeated shockwave lithotripsy (SWL) efficacy to help choose an appropriate treatment plan for patients with a single failed lithotripsy, reducing their treatment burden. PATIENTS AND METHODS: The clinical records and imaging data of 304 patients who underwent repeat SWL for upper urinary tract calculi (UUTC) at the Urology Centre of Shiyan People's Hospital between April 2019 and April 2023 were retrospectively collected. This dataset was divided into training (N = 217; 146 males [67.3%] and 71 females [32.7%]) and validation (N = 87; 66 males [75.9%] and 21 females [24.1%]) sets. The overall predictive accuracy of the models was calculated separately for the training and validation. Receiver operating characteristic (ROC) curves were plotted, and the area under the ROC curve (AUC) was calculated. The normalized importance of each independent variable (derived from the one-way analyses) in the input layer of the artificial neural network (ANN) model for the dependent variable (success or failure in repeat SWL) in the output layer was plotted as a bar chart. RESULTS: This study included 304 patients, of whom 154 (50.7%) underwent successful repeat SWL. Predictive models were constructed in the training set and assessed in the validation set. Fourteen influencing factors were selected as input variables to build an ANN model: age, alcohol, body mass index, sex, hydronephrosis, hematuria, mean stone density (MSD), skin-to-stone distance (SSD), stone heterogeneity index (SHI), stone volume (SV), stone retention time, smoking, stone location, and urinary irritation symptom. The model's AUC was 0.852 (95% confidence interval (CI): 0.8-0.9), and its predictive accuracy for stone clearance in the validation group was 83.3%. The order of importance of the independent variables was MSD > SV > SSD > stone retention time > SHI. CONCLUSION: Establishing an ANN model for repeated SWL of UUTC is crucial for optimizing patient care. This model will be pivotal in providing accurate treatment plans for patients with an initial unsuccessful SWL treatment. Moreover, it can significantly enhance the success rate of subsequent SWL treatments, ultimately alleviating patients' treatment burden.

PURPOSE: To assess outcomes of bilateral single-session percutaneous nephrolithotomy (PCNL) with minimally invasive techniques in pediatric population. MATERIALS AND METHODS: From August 2015 to July 2021, 45 children (including 12 infants) were treated with bilateral single-session PCNL, which included miniPCNL (12-16-Fr) and Microperc (4.8-Fr). Patient, stone and operation-related characteristics, stone-free rate (SFR) and complication rate (CR) were compared using ANOVA. Independent predictors were determined using multivariate linear regression. RESULTS: The mean stone burden was 3.2 cm in sum diameter for both kidneys. For bilateral kidneys, the mean operative time was 61.6min and SFR was 93.3%; CR was 53.3%, of which complications of Clavien grade 1 and 2 accounted for 46.7%. Bilateral Microperc, bilateral miniPCNL and Microperc plus miniPCNL was performed in 19, 14 and 12 children respectively. Both irrigation volume and postoperative stay were less in groups with Microperc. Both SFRs and CRs were satisfactory for the three groups. Self-limiting hematuria represented the most common complication of all cases (33.3%), especially in groups with miniPCNL. The stone burden was the only independent predictor for operative time (P < .001) and the postoperative complication (P = .008). Children with older age (P = .009), higher body mass index (P = .016) or a higher stone burden (P < .001) received larger irrigated fluid volume. Microperc was associated with less irrigated fluid volume (P = .001). Children with Clavien grade 3 complications (P = .004) spent prolonged postoperative hospital stay. CONCLUSION: With favourable SFR and acceptable CR, bilateral single-session PCNL with minimally invasive techniques might be an effective and safe procedure for pediatric nephrolithiasis.

PURPOSE: Evaluation of preliminary cosmetic and functional outcomes of biodegradable scaffolds covered with platelet-rich plasma in penile girth augmentation. MATERIALS AND METHODS: Between June 2016 and June 2018, 36 males who had a mean age of 28.91 years (range 20 - 48 years) with micropenis underwent this procedure. A mixture of platelets-fibrin glue and mesenchymal cells obtained from dermal fat tissue were prepared. Then the mixture was seeded on the pretreated tube-shaped poly lactic-co-glycolic acid scaffold and underwent a whole day of incubation. Following penile degloving, scaffolds were surgically implanted within the interface region of dartos and Buck's fascia. The 5-point Likert scoring scale was used to evaluate the patients' satisfaction with surgery. RESULTS: Patients followed up for 6-12 (8 ± 2.86) months. The penile length in an erected state before surgery was 6.5 - 12.5 cm (9.08 ± 1.6) which enhanced to 7 - 14 cm (10.59 ± 1.71) after surgery (P < .0001). The penile girth before and after surgery were 8.49 ± 1.53 and 10.91 ± 1.96 cm, respectively (P < .0001). An augment in penile length and girth of 1.5 and 2.6 cm were achieved, respectively. Patients appraised surgical intervention on a rating of one to five. The highest possible score (5) was assigned by 27 %, 33 % expressed a very good mark (4), and 19 % gave a good mark (3). CONCLUSION: Covering the scaffold with a mixture of Platelets-Fibrin glue and mesenchymal cells seems a safe and feasible method for penile reconstruction surgery. More studies should be done to determine the effect of platelets- fibrin glue and mesenchymal cells for treating micropenis.

Transplant renal artery stenosis is the most common vascular complication that occurs following kidney transplantation and can lead to graft dysfunction and even its loss. The present report describes A patient with endstage renal disease who underwent living related renal transplantation. He had oliguria and creatinine rise in the post-operative course but all doppler ultrasonography (DUS) during the 2 months post-operation for the renal graft showed a normal mean resistive index in the graft renal artery. Hemodialysis treatment started and continued for 4.5 months. On post-operative day 137, because of the patient's anuria and resistant hypertension, another DUS carried out and reported evidence that suggested arterial stenosis. A computed tomographic (CT) renal angiogram showed a small filling defect in the proximal graft artery that was highly suggestive for transplant renal artery stenosis (TRAS). Following angiography revealed a short linear stenosis. Endovascular intervention and stent placement were performed successfully for the patient on post-operative day 139. This case was initially diagnosed as ongoing acute rejection for which he received antirejection therapy without any significant improvement. After percutaneous transluminal angioplasty (PTA), serum creatinine trended down and urine output improved within 12 h, and they were stable at one-year follow up with a good renal function. It was noteworthy that, despite after a 4.5-month delay in diagnosis and maintenance need for dialysis, the patient responded to endovascular treatment and the graft function became normalized. Our case demonstrates that graft can be saved even if renal artery stenosis is diagnosed after several months of dialysis and diagnosis of end stage renal disease post transplantation.

PURPOSE: To evaluate Iranian urologists' approach to urethral stricture and assess how often they select open urethroplasty over minimally invasive procedures. MATERIAL AND METHODS: This cross-sectional observational study was conducted via www. SURVEY: porsline.ir among members of the Iranian urologists' community. The urologists were contacted via email and social media applications (e.g., WhatsApp, Telegram), and data, including their demographic information and years of practice, as well as questions related to their attitude towards the management of urethral stricture, were collected. RESULTS: A total number of 376 patients were included in the current survey. The specialty of reconstructive urology was selected by less than 2% (n=5) as their field of interest. Only 6.64% (n=25) of the urologists stated that they received adequate training for management of urethral stricture. Only about 5% (n=19), believed that according to scientific resources, chose open urethroplasty as the initial management. Almost 94% (n=353) did not perform any urethroplasties during the past year and about 0.2% (n=2) performed more than 20 open urethroplasties. For diagnosing urethral stricture, almost 99% of them chose RUG+VCUG, 72% chose urethrocystoscopy, and 69% chose uroflowmetry in the third place. For evaluation of urethroplasty postoperative outcomes, 76% (n=269) used RUG+VCUG, 15% (n=56) used Rigid Cystoscopy, and 8% (n=29) used Flexible Cystoscopy, Conclusion: Iranian urologists prefer minimally invasive procedures for treating urethral stricture, similar to other countries. This lack of urologists' interest in open urethroplasty is greatly due to poor training during the residency years and little experience with urethral strictures. Therefore, further considerations in order to improve urologists' knowledge and expertise for management of urethral stricture is recommended.

PURPOSE: Considering the inadequacy of PSA measurement in the diagnosis of prostate cancer, it is aimed to establish a potential liquid biopsy diagnostic panel. MATERIALS AND METHODS: 39 patients who underwent TRUS-biopsy and 15 healthy volunteers were included. Approximately 15 ml of venous blood samples taken from healthy volunteers and patients before biopsy were separated as plasma. Hypermethylation status of GSTP1 and RASSF1:RASSF2 genes was revealed in cfDNA materials collected from plasma samples. Correlation of this epigenetic change detected in PCa, BPH and healthy volunteer groups with pathology results was examined. RESULTS: Pathology reports of 39 patients included were 13 PCa, 3 ASAP, 3 HGPIN, and 20 BPH. In total, 3 of the patients with PCa had positive GSTP1, 4 had RASSF1 and 9 had positive RASSF2 methylation. It was seen that RASSF2 had the highest sensitivity (69%), specificity (39%) and NPV (80%), while RASSF1 had the highest PPV (30%). When the binary combinations of genes were examined it was observed that the GSTP1:RASSF1 combination had the highest sensitivity (46%), specificity (76%) and NPV (82%). When the methylation of all three genes was examined, it was observed that the sensitivity was quite low (8%), but the specificity (83%) increased significantly. CONCLUSION: Although we observed that the GSTP1 and RASSF1 methylation positivity rates that we examined in our study were higher in patients without prostate cancer, we found that the RASSF2 methylation rate was higher in patients with prostate cancer. randomized controlled studies are needed.

PURPOSE: To evaluate the performance of the European Organization for Research and Treatment of Cancer (EORTC) and the Spanish Urological Club for Oncological Treatment (CUETO) risk scoring models in non-muscle-invasive bladder cancer (NMIBC) patients defined as high risk according to European Association of Urology guidelines and managed based on current recommendations. MATERIAL AND METHODS: Data from 187 high-risk NMIBC patients treated at a tertiary center between July 2010 and November 2021 were analyzed retrospectively. One- and five-year recurrence- and progression-free survival were assessed for each patient using the EORTC and CUETO risk scores. The patients were divided into four risk groups according to their risk scores as low, medium-low, medium-high and high risk, as indicated in the models. Discriminative ability was evaluated with the Harrell's concordance index (c-index). RESULTS: Both risk scoring models overestimated the risk of recurrence and progression at one and five years. Only the prediction of recurrence at five years in the high risk group according to the CUETO model was compatible with our cohort. CUETO (c-indices for recurrence and progression were 0.802 and 0.834, respectively) exhibited better discrimination than EORTC (0.722 for recurrence and 0.752 for progression) in the prediction of disease recurrence and progression. CONCLUSION: The CUETO model was superior to the EORTC model in predicting recurrence and progression and stratifying patients with different prognoses in our high-risk NMIBC patient population treated according to current guideline recommendations. However, both models overestimated the probability of disease recurrence and progression. Only the probability of recurrence at five years in the high-risk group of the CUETO model was compatible with our cohort.

PURPOSE: Traditionally, an omental flap is employed to reduce the risk of recurrence of vesicovaginal fistula (VVF) repair. In this study, we employed a modified surgical technique wherein the vaginal defect was closed using Connell sutures, without incorporation of an omental flap, aiming to mitigate potential complications. MATERIAL AND METHOD: Between 2010 to 2018, the current randomized clinical trial was conducted on 52 women who were candidates for open fistula repair. The patients were randomly allocated into two groups. In one group, the conventional method of fistula repair was performed involving an omental flap, while in the other group, we used a modified approach with a variation in the vaginal wall closure technique. In-hospital variables, including the length of surgery, hospital stay, and occurrences of ileus, were recorded. Patient follow-up extended for one year, with assessments conducted one, six, and twelve months postoperatively. These evaluations encompassed pad test to ascertain success rates and identify any potential complications. RESULTS: The final analysis comprised 49 patients, with an average age of 46.5 years. Baseline characteristics were comparable between the two groups (P-values > 0.05). The modified technique was associated with significantly reduced surgical duration (P = ˂ 0.001), and shorter hospital stays (P < 0.001). Ileus occurrence was reduced, but it was not significant(P = 0.856). However, the success rate showed no significant difference between the groups, with a success rate of 100% for the modified technique compared to 91.6% for the classic O'Conner method (P = 0.288). CONCLUSION: Based on the findings of this study, vaginal wall closure using Connell sutures during VVF repair demonstrates a success rate equivalent to the classic approach involving an omental flap. Moreover, this technique presents a reduced incidence of adverse effects, along with decreased surgical duration, hospital stay, and postoperative ileus.

PURPOSE: Postoperative pulmonary embolism is a leading cause of mortality in patients undergoing major urologic surgeries, presenting a complex challenge in balancing the risks of venous thromboembolism (VTE) and perioperative bleeding. This study examines the current evidence on thromboprophylaxis in urological procedures, focusing on procedure-specific considerations. METHODS: Literature on thromboprophylaxis in urological procedures was reviewed during the past decade. RESULTS: Various mechanical thromboprophylaxis methods, such as compression stockings, pneumatic compression devices, foot pumps, mobilization, and exercises, are available preventive measures. Additionally, unfractionated heparin (UFH) and low molecular weight heparin (LMWH) are commonly used pharmacological agents for VTE prevention, with the choice between mechanical, pharmacological, or combined approaches tailored to individual patient characteristics and surgical requirements. Patient risk stratification into low, medium, and highrisk categories based on age, BMI, and VTE history guides the selection of thromboprophylaxis strategies. Surgical procedures are categorized as oncological or non-oncological, with uro-oncological surgeries posing a higher VTE risk than non-oncological procedures. Consequently, a combination of pharmacological and mechanical prophylaxis is typically recommended for uro-oncological patients, while pharmacological prophylaxis is reserved for high-risk individuals undergoing non-oncological surgeries. Mechanical prophylaxis is advised for high-risk patients undergoing procedures with elevated VTE risk. CONCLUSION: This study summarized an optimal thromboprophylaxis protocol taking into account patient risk factors and the specific urological procedure.

PURPOSE: This review presents a clinical approach to genetic issues in male infertility. Unlike other related reviews that discuss different types of genetic diseases (such as Klinefelter and Down syndrome), this review focuses on the clinical features that result from these genetic problems (such as azoospermia and oligospermia). METHODS: A narrative review of the clinical literature in PubMed was conducted using keywords related to male infertility, recurrent pregnancy loss, recurrent in vitro fertilization failure, and genetics. The search included articles with English reviews published online after 2020. Headlines were defined based on the available literature, and after a critical review of each manuscript, clinical facts were classified under the corresponding headlines, and a primary draft was written. RESULTS: 29 relevant articles were selected from the search. According to the literature, there are clinical genetic approaches for azoospermia, severe oligospermia, severe teratospermia, severe asthenospermia, recurrent miscarriage, and recurrent in vitro fertilization failure. CONCLUSION: Although many mutations that can affect male fertility and spermogram have been identified, only a few have clinical predictive value.

PURPOSE: To analyze the perioperative factors that influence the risk of biochemical recurrence (BCR) in patients with localized PCa undergoing radical prostatectomy Materials and Methods: A total of 457 patients, operated by 2 surgeons in our high-volume oncological center were included in the initial database. Patients who underwent RP for clinically localized PCa in our clinic from 2016 to 2021 were included in the study. Perioperative data were retrospectively reviewed for this study. Follow-up data including post-operative PSA and adjuvant treatment was prospectively gathered by contacting the patients or from the follow-up consultation. Final database was composed of 366 patients who underwent open or 3D laparoscopic RP. Statistical analysis was performed to emphasize the most powerful parameters that influence the BCR. Results: Accounting for multivariable analysis, 4 parameters were statistically significant: initial PSA (iPSA), Gleason score, vascular involvement and positive surgical margins. For the group of patients with no positive margins, 3 parameters were statistically significant: iPSA above 10,98 ng/mL (AUC=0,71); lymph node involvement and Gleason score. Multivariable Cox regression showed that positive margins and iPSA had a significant impact on the time to BCR. Patients that received adjuvant therapy were excluded from the study. Out of the whole cohort, 27,3% of patients presented BCR. CONCLUSION: Perioperative factors need to be carefully analyzed and a detailed follow-up needs to be conducted in order to assess the risk of biochemical recurrence, resulting in the optimal time for adjuvant treatment implementation.

PURPOSE: To compare the efficiency and safety between retroperitoneal laparoscopic nephrectomy and traditional open nephrectomy to treat autosomal-dominant polycystic kidney disease before kidney transplantation. MATERIALS AND METHODS: A total of 57 patients diagnosed with huge autosomal-dominant polycystic kidney disease between 2000 and 2020 at our center were included in this study. Patients were divided into a retroperitoneal laparoscopic (RL; n=23) group and traditional open (TO; n = 34) group. We retrospectively analyzed and compared preoperative and perioperative variables between the two groups. RESULTS: Patients in the RL group showed a longer operation time (201.09±83.76min) compared to patients in the TO group (113.38 ± 51.84min, p < 0.001). The RL group also showed significantly less intraoperative blood loss (p = 0.025) and less intraoperative blood transfusion volume (p = 0.016) compared to the TO group. Meanwhile, time of gastrointestinal function recovery, bed leave, catheter indwelling and postoperative hospitalization in the RL group were 2.13 ± 0.63, 1.30 ± 1.0, 5.22 ± 2.09, 7.35±2.48 days, respectively, which were significantly shorter than the TO group (p < 0.05). Pain degree of patients during the first 48 hours after operation was similar between the RL and TO groups, but the opioid use percentage in the RL group was 8.70% (2/23) and was lower than the 26.47% (9/34) in the TO group (p = 0.022). Meanwhile, 5 and 23 patients exhibited postoperative complications in the RL and TO groups, respectively (p < 0.001). CONCLUSION: Both retroperitoneal laparoscopic nephrectomy and traditional open surgery are feasible to treat huge polycystic nephrectomy. However, patients who undergo retroperitoneal laparoscopic nephrectomy experience higher levels of safety and recover more rapidly.
