RESUMO
OBJECTIVES: This study aims to share the experiences and outcomes of laparoscopic pneumovesical repair for vesicovaginal fistulas (VVF). MATERIALS AND METHODS: A retrospective review of medical records from a single institution over 10 years was conducted. The focus was on patients who underwent VVF repair using a pneumovesical approach with three 5 mm laparoscopic ports. The study evaluated perioperative parameters, postoperative outcomes, and complication rates to assess the efficacy and safety of this surgical method. Cumulative sum (CUSUM) analysis was used to determine the learning curve based on operative time. RESULTS: Of the 26 patients with VVF, 23 (88.5%) had successful fistula closure after the first surgery. One patient required open surgery conversion due to challenges in maintaining pneumovesicum, and two experienced recurrences, although successful repairs were achieved in subsequent surgeries. The average patient age was 47.4 years, with a mean operative time of 99.9 min. The postoperative hospital stay averaged 9.1 days, and catheterization lasted about 11 days. The CUSUM chart indicated a learning curve, with fluctuations until the 19th case, followed by a consistent upward pattern. CONCLUSION: Laparoscopic pneumovesical VVF repair is an effective and safe technique, especially suitable for fistulas near the ureteral orifice or deep in the vaginal cavity. The method demonstrates favorable outcomes with minimal complications and allows for easy reoperation if necessary.
RESUMO
INTRODUCTION: This study investigated the learning curve of retrograde intrarenal surgery (RIRS) in patients with medium-sized stones using cumulative sum analysis (CUSUM) to evaluate the competence and proficiency of three new surgeons during their first RIRS procedures. MATERIALS AND METHODS: We conducted a retrospective review of 227 patients from 2019 to 2022 at a single institution. The patients were divided into four groups based on the operating surgeon: tutor surgeon (85 patients), newbie surgeon A (21 patients), newbie surgeon B (85 patients), and newbie surgeon C (36 patients). Patients had one or multiple stones with the largest stone diameter fell within the range of 10-30 mm. Fragmentation efficacy was calculated as "removed stone volume (mm3) divided by operative time (minutes)." CUSUM analysis monitored changes in fragmentation efficacy and validated surgical outcomes. RESULTS: No statistically significant differences were observed in the total stone volume, maximum stone size, or total operation time between the three newbie surgeons and the tutor surgeon. The mean fragmentation efficacy value was comparable among the newbie surgeons, but significantly different from that of the tutor surgeon. The minimum acceptable fragmentation efficacy level was set at 25.12 mL/min, based on the tutor's average value. The CUSUM curves for the three surgeons initially remained relatively flat until Cases 12-15, after which they increased and eventually plateaued. Stone-free rates and postoperative complications did not differ significantly among the surgeons. CONCLUSION: Learning curve analysis for the three newbie surgeons indicated that approximately 12-15 cases were required to reach a plateau.

PURPOSE: Patients with cancer have a high risk of depression. However, a few studies have assessed differences in the incidence of depression among patients with prostate cancer (PC) based on whether they received radiotherapy (RTx) or surgical treatment. MATERIALS AND METHODS: We analyzed data from the National Health Insurance Sharing Service database regarding the entire Korean adult population with PC (n=210,924) between 2007 and 2017. The adjusted hazard ratios (HRs) of depression associated with treatment were estimated using propensity score-matched Cox proportional hazards models and Kaplan-Meier survival analyses. RESULTS: Our final cohort comprised 9,456 patients with PC; of which, 8,050 men underwent surgery. During a mean follow-up duration of 7.1 years, 503 (5.3%) patients were newly diagnosed with depression. A significant difference in the incidence of depression was noted between the RTx and surgery groups (RTx vs. surgery: 5.55% vs. 5.28%; p=0.011) in the unmatched cohort. In the matched cohort, older age (≥70 years, HR: 1.596, p<0.001) and poor Charlson comorbidity index scores (HR: 1.232, p=0.039) were correlated with the risk of depression. In addition, the adjusted HR for depression in the surgery group was 0.843 (p=0.221) compared with that in the RTx group. Kaplan-Meier analyses revealed that no significant difference in the cumulative probability of persistent depression was detected between the RTx and surgery groups in matched cohort (p=0.3386). CONCLUSIONS: In this nationwide population-based study, no significant differences in the risk of depression were observed between the surgical and RTx groups.
RESUMO
PURPOSE: To analyze the presentation of mumps and mumps orchitis using the National Health Insurance Service Database (NHISD). MATERIALS AND METHODS: Using information from the NHISD representing all cases of mumps in Korea, data regarding mumps orchitis were analyzed. The International Classification of Diseases, Tenth Revision, and Clinical Modification codes were used for diagnosis. The incidence estimates of the number of mumps cases were analyzed using the Statistical Analysis System (SAS) software. RESULTS: Based on the NHISD, 199,186 people were diagnosed with mumps, and males accounted for 62.3% cases. Teen males accounted for 69,870 cases, the largest number of patients diagnosed with mumps. The annual incidence of mumps increased every year (poisson regression, hazard ratio [HR] 1.026, 95% confidence interval [CI] 1.024-1.027; p<0.025). The risk of mumps was lower in females than that in males (poisson regression, HR 0.594, 95% CI 0.589-0.599; p<0.001). Of the 199,186 patients diagnosed with mumps, 3,872 patients (1.9%) had related complications. Among the mumps complications, the most diagnosed complication was mumps orchitis, which was seen in 41.8% of the males. Mumps orchitis cases accounted for less than 1.5% of the patients with mumps in minors under the age of 20 years and was somewhat higher in 2009 and 2013-2015. CONCLUSIONS: Among the complications related to mumps, meningitis was most common in females, while orchitis was dominant in males. Mumps orchitis also shows periodic outbreaks but is particularly prevalent in adults, which suggests the potential need for additional vaccination against mumps.

BACKGROUND: To analyze the incidence of renal trauma using the National Health Insurance Service Database (NHISD). METHODS: Using the NHISD, representative of all upper urinary tract injuries in Korea, data regarding renal trauma were analyzed. The International Classification of Diseases, Tenth Revision Clinical Modification codes were used to identify the diagnoses. The incidence estimates of renal traumas were analyzed using Poisson regression analysis. Risk factors for high-grade renal trauma were estimated using multivariable logistic regression analyses. RESULTS: Patients with renal trauma were identified from a nationwide database collected by the National Health Insurance Service of Korea between 2012 and 2016. Among 37,683 individuals with renal trauma, 1,293 (3.4%) were diagnosed with high-grade renal trauma. Surgical therapy was performed in 995 (2.6%) patients with renal trauma and 184 (14.2%) patients with high-grade renal trauma. Renal trauma occurred in all age groups, and the ratio between men and women was approximately 3:1. Men and women experienced 8,000 (31.82/100,000) and 2,365 (9.52/100,000) renal trauma in 2013 (total 10,365, 20.73/100,000) and 5,243 (20.56/100.000) and 2,168 (8.58/100,000) in 2016 (total 7,411, 14.60/100,000), respectively. In multivariable analysis, female sex, age (age; 41-60 and 61-80 years), and comorbidity of peripheral vascular disease, renal disease, and malignancy were revealed as risk factors for high-grade renal trauma. CONCLUSION: Annual incidence of renal trauma is 17.33 per 100,000 population from 2012 to 2016. The incidence of kidney damage decreased gradually from 2013 to 2016, and the majority of renal trauma cases were low-grade. Conservative management was the preferred treatment modality in most patients with renal trauma, including those with high-grade renal trauma.

PURPOSE: The prevalence of catheter-associated urinary tract infections (CAUTIs) varies from 5% to 8.2%, and the risk of infection increases by 5% to 7% per day of primary indwelling. We investigated whether a novel biofilm inhibitory mechanism using an inhibitory silicone urethral catheter (a coated Foley catheter) can reduce CAUTIs compared to conventional non-coated Foley catheters. MATERIALS AND METHODS: This study prospectively analyzed the difference in the incidence of CAUTIs in patients who underwent radical cystectomy with an orthotopic neobladder for bladder cancer and received a coated or conventional non-coated catheter. Additionally, differences in bacterial colonization between the groups were analyzed using a catheter-tip bacterial culture test. RESULTS: Eighty-five patients were randomized into the "coated Foley catheter" group (abbreviated as "case" group; 41 patients) and a control group (44 patients). The two groups were identical except for their surgical history. The incidence of CAUTIs 2 weeks after radical cystectomy was 21.95% (case) and 27.27% (control), with no significant difference between the two groups. However, when the catheter was removed 2 weeks after surgery, the catheter tip culture test revealed significant bacterial colonies in 25 (60.98%) and 38 (86.36%) patients in the case and control group, respectively. No catheter-related postoperative side effects were observed in either group. CONCLUSIONS: The incidence of CAUTIs in the two groups did not differ according to the catheter material. However, the catheter bacterial culture test showed that bacterial colonization was significantly suppressed on the Bi-Fi Free technology catheter, which comparatively inhibited biofilm formation.

Bladder cancers have high recurrence rates and are usually removed via transurethral resection of bladder tumor (TURBT). Recently, some reports showed that the anesthetic method may affect the recurrence rates of bladder cancers. The purpose of this population-based study was to compare the effect of anesthetic methods with the recurrence rates of bladder cancers in South Korea. A total of 4439 patients were reviewed retrospectively using the data of the Korean National Health Insurance (NHI) claims database from January 2007 to December 2011. Patients were divided into 2 groups who received general (n = 3767) and regional anesthesia (n = 582), and were followed up until September 2017. Propensity score matching was conducted to reduce the effect of confounding factors. After using propensity score matching with a multivariable Cox regression model, age (p < 0.001), sex (p < 0.001), hypertension (p = 0.003), diabetes mellitus (p = 0.001), and renal disease (p < 0.001) were significantly associated with bladder cancer recurrence. However, there were no significant differences in the recurrence rates of bladder cancers in patients who received general anesthesia and spinal anesthesia for TURBTs. This study revealed that there is no relationship between the anesthetic method and bladder cancer recurrence. Either general anesthesia or regional anesthesia can be used depending on the situation in patients receiving TURBT. Future prospective studies are warranted to confirm the association between the anesthetic method and the recurrence rates of bladder cancer.
RESUMO
PURPOSE: To evaluate the clinical impact of strict selection criteria for active surveillance (AS) of prostate cancer in a Korean population. MATERIALS AND METHODS: A single-center, prospectively collected AS cohort from December 2016 to February 2019 was used. Following pre-determined criteria, patients were categorized into "strict AS" and "non-strict AS" groups. Clinicopathological progression-free survival (PFS) and treatment-free survival (TFS) of the two groups were compared using the Kaplan-Meier curve and log-rank test. Age-adjusted hazard ratios for clinicopathological progression was calculated using Cox proportional regression analysis. RESULTS: Of 54 eligible patients, 25 and 29 were assigned to "strict AS" and "non-strict AS," respectively. Clinicopathological progression and definitive treatment rates were 24.0% (6 of 25 patients) vs. 51.7% (15 of 29 patients) and 32.0% (8 of 25 patients) vs. 62.1% (18 of 29 patients) in "strict AS" and "non-strict AS" groups. Progress to high-risk cancer (pathologic T3 or surgical Gleason Grade 2 over) in radical prostatectomy was higher in "non-strict AS" than "strict AS". PFS (mean 34.6±2.9 mo vs. 22.6±2.7 mo; p=0.025) and TFS (mean 31.8±3.2 mo vs. 19.6±2.4 mo; p=0.018) favor the "strict AS" group than "non-strict AS" group. Age-adjusted hazard ratio for clinicopathological progression of strict criteria was 0.36 (95% confidence interval, 0.14-0.94; p=0.04). CONCLUSIONS: PFS and TFS were better in the "strict AS" group than in the "non-strict AS" group. This finding should be informed to relevant patients during decision making and considered in Korean guidelines.

RESUMO
ABSTRACT Purpose To evaluate the usefulness of natural killer cell activity (NKA) in diagnosing prostate cancer (PC). Materials and Methods The medical records of patients who underwent transrectal prostate biopsy (TRBx) at Korea University Ansan Hospital between May 2017 and December 2017 were retrospectively reviewed. NKA levels were measured using NK Vue® Tubes (ATgen, Sungnam, Korea). All blood samples were obtained at 8 AM on the day of biopsy. Patients with other malignancies, chronic inflammatory conditions, high prostate-specific antigen (PSA) level (>20ng/mL), or history of taking 5-alpha-reductase inhibitor or testosterone replacement therapy were excluded. Results A total of 102 patients who underwent TRBx for PC diagnosis were enrolled. Among them, 50 were diagnosed with PC. Significant differences in age and NKA level were observed between the PC and no-PC groups. Receiver operating characteristic (ROC) curve analysis showed that the optimal cut-off of NKA level for the prediction of PC was 500pg/dL, with a sensitivity of 68.0% and a specificity of 73.1%. In addition, NKA level (0.630) had the greatest area under the ROC curve compared to those for the ratio of total PSA to free PSA (0.597) and PSA density (0.578). Conclusions The results of this pilot study revealed that low NKA and high PSA levels were likely to be associated with a positive TRBx outcome. NKA detection was easy and improved the diagnostic accuracy of PC.

Purpose: To evaluate if preoperative sterile pyuria can be a prognostic factor for intravesical recurrence (IVR) and overall survival (OS)in patients with upper tract urothelial carcinoma (UTUC) undergoing surgery. Materials and Methods: We retrospectively reviewed the medical records of patients who were diagnosed with UTUC from October 2003 to December 2016 at Korea University Medical Center. Sterile pyuria was defined as urine containing five or more white blood cells per high-power field in the absence of bacteria in urine culture. We used a stepwise multivariable Cox proportional hazards model to assess the independent effects of the prognostic factors for IVR and OS. Results: We investigated a total of 176 patients who were diagnosed with UTUC. Among them, 91 (51.7%) patients had preoperative sterile pyuria. There were no significant differences in the baseline characteristics between the pyuria and non-pyuria groups concerning tumor grade, T stage, tumor multiplicity, and recurrence history. However, there was a significant difference in the IVR between the two groups. In the multivariable analysis, preoperative sterile pyuria, diabetes mellitus, high-grade tumor, and lymphovascular invasion were revealed as independent risk factors for IVR, and only lymphovascular invasion was identified as an independent risk factor for OS. Conclusions: Preoperative sterile pyuria is significantly associated with IVR in patients with UTUC undergoing surgery, but it is not associated with OS. Furthermore, diabetes mellitus, high-grade tumor, and lymphovascular invasion are also independent prognostic factors for these patients.

Treatment strategies for metastatic urothelial carcinoma (mUC) have evolved dramatically over the last decade. The emergence of immunotherapeutic agents, especially immune checkpoint inhibitors, has been the most significant development. Immunotherapy increased the overall survival rate of patients with mUC and provided a durable response. The success of immune checkpoint inhibitors further led to the development of novel agents that regulate the immune system within the tumor microenvironment. However, despite some success with immune checkpoint inhibitors, researchers are still developing new agents, including small molecule tyrosine kinase inhibitors, mammalian target of rapamycin (mTOR) inhibitors, and novel fusion proteins, tailored for targets other than immune checkpoint inhibitors. Novel treatment strategies are being developed rapidly with ongoing pre-clinical trials. Here, we outline promising new therapies that are expected to improve survival rates for patients with mUC.
RESUMO
Herein, we review the assessment of quality-of-life (QoL) in radical cystectomy (RC) patients, summarize the result of studies for different surgical approaches, and provide an overview of patient management, as well as other considerations. In this review article, we reviewed the QoL research and research tools for patients undergoing RC, including urinary diversion methods, gender differences, and surgical methods (open surgery vs. robotic surgery). This narrative review focused primarily on articles indexed in PubMed, Embase, Scopus, and Google Scholar databases. We did not used formal search strategy and meta-analysis was not performed.
RESUMO
BACKGROUND: Potency preservation often does not meet expectation despite nerve-sparing prostatectomy. OBJECTIVE: To set the protocol for intraoperative cavernous nerve monitoring and mapping during robot-assisted radical prostatectomy (RARP), and to evaluate its safety and clinical feasibility. DESIGN, SETTING, AND PARTICIPANTS: A prospective phase I/II, feasibility study was performed. A total of 30 patients with prostate cancer who underwent RARP at a high-volume tertiary academic hospital were enrolled. SURGICAL PROCEDURE: Pudendal somatosensory evoked potential, bulbocavernosus reflex, spontaneous corpus cavernosum electromyography (CC-EMG), median nerve stimulation evoked CC-EMG, and neurovascular bundle (NVB)-triggered CC-EMG with various stimulation protocols were assessed during conventional RARP under total intravenous anesthesia with controlled muscle relaxation. MEASUREMENTS: The primary endpoint was the completion rate of planned surgery and assessment. Adverse events, and erectile and urinary functions were evaluated within 1 yr. CC-EMGs were graded and correlated with functional outcomes. RESULTS AND LIMITATIONS: The completion rate was 100%. Only one patient experienced adverse events, which were not related to study intervention. Grades of CC-EMGs including NVB-triggered CC-EMG before prostate removal were associated with baseline five-item International Index of Erectile Function (IIEF-5) score (grades 0-1, 4.6±2.7; grade 2, 13.2±6.8; grades 3-4, 16.6±5.9; p=0.003). Furthermore, grades of CC-EMGs including NVB-triggered CC-EMG after prostate removal were significantly associated with potency recovery (grade 0, 12.5%; grade 1, 0%; grade 2, 33.3%; grades 3-4, 100% at 12 mo; p=0.005) and postoperative IIEF-5 scores at all evaluation time points (grades 0-1, 2.6±2.8; grade 2, 4.3±5.8; grades 3-4, 15.7±11.0 at 12 mo; p=0.003). CONCLUSIONS: We successfully established the protocol for safe intraoperative cavernous nerve monitoring and mapping using CC-EMG during RARP. Its grades were well correlated with erectile function. PATIENT SUMMARY: In this first-in-human feasibility study, we successfully established the protocol for safe intraoperative cavernous nerve monitoring and mapping method during robot-assisted radical prostatectomy. The results were significantly associated with erectile function. Evaluation of clinical efficacy to preserve potency seems worthy of further optimization and investigation in confirmatory clinical trials.

The aim of this study was to evaluate whether balneotherapy might be effective in patients with chronic pelvic pain (CPP) in the short term. This was an open and prospective pilot study. The balneotherapy programme was performed in a spa resort located in Wando Island, Republic of Korea from August 26 2018 to September 1 2018. It consisted of 10 heated seawater baths (38 °C, 20 minutes) and 10 mud-pack applications (40 °C, 10 minutes) for five days. Sixteen patients were enrolled. Upon analysing responses from a patient questionnaire, we found improvement in parameters such as pain, bladder irrigation symptoms and quality of life after balneotherapy. Inflammatory marker IL-1 and TNF-α was significantly decreased after treatment compared to baseline. There were no adverse events during treatment. Our data suggest that five-day balneotherapy can be beneficial for patients with CPP in the short term.Impact statementWhat is already known on this subject? The majority of articles in the field of balneotherapy discuss the treatment of rheumatic or dermatological disease. However, data on the effectiveness of balneotherapy for chronic pelvic pain are very limited.What the results of this study add? Our study suggests that balneotherapy can be beneficial for patients with CPP in the short-term. The duration of balneotherapy was five days, which is shorter than that of the European studies. Intuitively, it may be doubtful whether short-term therapy has any practical effect. As most people living in Korea have a vacation period of about one week each in summer and winter, the choice of a five-day programme in our study reflects the reality of vacation schedules.What the implications are of these findings for clinical practice and/or further research? Further studies are necessary to demonstrate the persistence of these benefits on the long term, as well as their existence in appropriate control group and different duration of treatment.

BACKGROUND: E-cadherin has emerged as a prognostic factor of urothelial cell carcinoma. In the present work we investigate the relationship between expression of E-cadherin and clinical outcomes, following radical nephroureterectomy for upper tract urothelial cell carcinoma. METHODS: We systematically searched PubMed, Embase, Cochrane Library, and Web of Science databases to identify eligible studies published until July 2017. RESULT: Six studies were included in the meta-analysis, with a total of 1014 patients. The pooled hazard ratio (HR) for recurrence-free survivor was 0.69 (95% confidence interval [CI], 0.44-1.09, Iâ=â63%, Pâ=â.04). Also, reduced E-cadherin was not significantly associated with poor cancer-specific survivor (pooled HR, 1.40; 95% CI, 0.66-1.43, Iâ=â54%, Pâ=â.11). The pooled HR for overall survivor was not statistically significant (pooled HR, 0.68; 95% CI, 0.32-1.46, Iâ=â80%, Pâ=â.007). The results of the Begg and Egger tests suggested that publication bias was not evident in this meta-analysis. CONCLUSIONS: Reduced E-cadherin expression did not appear to be significantly associated with disease prognosis after nephroureterectomy in the meta-analysis. However, further high quality, prospective studies are warranted to better address this issue.

Purpose: To establish a prospective, comprehensive, multidisciplinary, bio-bank linked genitourinary cancer cohort based on standard real practice. Materials and Methods: We established the Seoul National University Prospectively Enrolled Registry for Genitourinary Cancer (SUPER-GUC), a prospective cohort clinical database and bio-specimen repository system for prostate cancer (SUPER-PC), renal cell carcinoma (SUPER-RCC), and urothelial cancer (SUPER-UC) at a high-volume, tertiary institution. Each cohort consists of several sub-cohorts based on treatment or disease status. Detailed longitudinal clinical information, and general and disease specific patient-reported outcomes are captured. We use the same evaluation format and questionnaires for all participating departments. Patients' blood, urine, tumor, and normal tissues are collected. The number of registered patients and their basic characteristics are summarized. For the surgical sub-cohort, study participation, bio-specimen, and tissue banking rates are analyzed. Results: Since March 2016, 11 sub-cohorts for all disease statuses have been opened, ranging from low-risk localized to metastatic disease. SUPER-PC, SUPER-RCC, and SUPER-UC enrolled 929, 796, and 1,221 patients, respectively. Study participation, bio-sampling, and fresh frozen tumor banking rates of surgical sub-cohorts were 89.0% to 93.1%, 91.2% to 99.1%, and 56.9% to 79.1%, respectively.

PURPOSE: Previous studies have suggested that androgen deprivation therapy (ADT) is associated with cerebral infarction. However, conflicting results have been reported by other researchers. The aim of this study was to evaluate the association between ADT and cerebral infarction in patients with prostate cancer (PC) using big data. MATERIALS AND METHODS: Using information from the National Health Insurance Service database representative of the entire Korean adult PC population (n = 206 735), data regarding ADT and cerebral infarction between 2009 and 2016 were analyzed. Adjusted hazard ratios for cerebral infarction associated with ADT were estimated using propensity score-matched Cox proportional hazards models and Kaplan-Meier survival analyses. RESULTS: The final cohort comprised 36 146 individuals with PC, including 24 069 men (66.6%) who underwent ADT. During the mean follow-up of 4.1 years, 2792 patients were newly diagnosed with cerebral infarction. In the unmatched cohort, there was a significant difference in the annual incidence of cerebral infarction between the ADT and non-ADT groups (22.8 vs 14.6 per 1000 person-years, respectively). However, there was no significant difference between the ADT and non-ADT groups in the matched cohort (14.9 vs 14.6 per 1000 person-years). The adjusted hazard ratio for cerebral infarction for PC patients who underwent ADT was 1.045 (95% CI 0.943-1.159; P = 0.401) compared with those who did not undergo ADT. In addition, the cumulative duration of ADT was also not associated with an increased risk for cerebral infarction. However, older age, hypertension, diabetes, myocardial infarction, congestive heart failure, peripheral vascular disease, renal disease, dementia, and atrial fibrillation were revealed to be factors contributing to cerebral infarction. CONCLUSION: This nationwide population-based study revealed that ADT was not associated with cerebral infarction after adjusting for potential confounders.

PURPOSE: To describe our initial experience with a novel method of adenoma retrieval using a pneumovesicum (PNV) after Holmium laser enucleation of the prostate (HoLEP). METHODS: From January 2016 to April 2018, a total of 93 consecutive patients treated with HoLEP were enrolled in this study. For tissue morcellation, we used the PNV morcellation technique for an initial series of 21 patients and the conventional technique (Lumenis VersaCut) for a consecutive series of 72 patients. We compared efficiency and safety between the novel technique and the traditional technique. Subgroup analysis was performed to assess the effectiveness of the current technique in the large prostate (>70 mL). RESULTS: There were significant differences in mean age and prostate volume between the 2 groups. However, there were no significant differences in the baseline characteristics and preoperative parameters in the subgroup analysis of large prostates (>70 mL). The mean morcellation efficiency was higher (8.50±1.94 minutes vs. 1.76±0.45 minutes, P<0.05) and the time of morcellation (7.81±1.25 minutes vs. 34.04±11.14 minutes, P<0.05) was shorter in the PNV group. Moreover, there were no significant differences between groups in hospitalization period (2.62±1.10 days vs. 2.90±1.26 days, P=0.852) and any other postoperative events, including recatheterization, reoperation, clot retention, and urethral stricture (P-value range, 0.194-0.447). In the PNV group, there were some cases of procedure-related complications, including postoperative extravesical leakage (5th case), clot retention (8th case), and recatheterization (9th case). CONCLUSION: This method has a higher tissue retrieval efficacy, with the advantage of excellent visibility compared to conventional morcellation. The current method can be applied when a transurethral morcellator is out of order or cannot be used.
