Purpose: The purpose of study was to compare oncologic outcomes (recurrence-free survival [RFS], cancer-specific survival [CSS], and overall survival [OS]) and early complication (within 30 days) after radical cystectomy (RC) between old patients (70–79 aged) and oldest-old patients (above 80).Materials and Methods: This retrospective study reviewed total 340 patients with urothelial carcinoma of bladder who received RC between November 1996 and December 2018. The patients were divided into 2 groups by age, 307 patients aged 70–79 and 33 patients aged above 80. Baseline characteristics, perioperative outcomes and early complication were compared between the 2 groups. Kaplan–Meier (K-M) survival analysis was used to estimate RFS, CSS, OS, and multivariable Cox proportional hazard models were used to identify factors predicting RFS, CSS, OS.Results: The results of both groups did not statistically differ from each other in most clinicopathologic baseline characteristics and perioperative information. Both groups showed similar 30-day complication rates (59.3% vs. 60.3%, p=0.210). K-M showed 3-year survival rate, RFS was shorter in oldest-old group (41.4% vs. 56.7%) but not statistically different (p=0.063). Oldest-old group showed similar 3-year CSS (78.1% vs. 74.6%, p=0.779) but worse OS (51% vs. 58%, p=0.047) compared with the old group. Common factor affecting RFS, CSS, and OS were T stage and N stage (all p

Purpose: To evaluate the performance of combining prostate health index (PHI) and Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) for detection of clinically significant prostate cancer (csPCa).Materials and Methods: We retrospectively reviewed patients who underwent prostate biopsy for elevated prostate-specific antigen (PSA) ≥2.5 ng/mL and/or abnormal digital rectal examination. Serum markers for PSA, free PSA (fPSA), and [-2] proPSA (p2PSA) were measured, and PHI was calculated as ([p2PSA/fPSA]×[PSA]1/2). Multiparametric magnetic resonance imaging was performed using a 3.0T scanner and scored using PI-RADSv2. csPCa was defined as either grade group (GG) ≥2 disease or GG1 cancer detected in >2 cores or >50% of positive on biopsy. Univariable and multivariable logistic regression modelling, along with receiver-operating characteristic (ROC) curve analysis was used to predict the probability of csPCa.Results: Of the total 358 patients, 159 (44.4%) were diagnosed with csPCa. On univariable analysis, age, PSA density (PSAD), PHI and PI-RADSv2 were associated with csPCa. The area under the ROC curve (AUC) of baseline model incorporating age and PSAD was 0.663. The AUC of combining PHI and PI-RADSv2 to baseline model was higher than that of PHI alone to baseline model (0.884 vs. 0.807, p

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes.Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of

Purpose: We investigated the predictive factors for acute urinary retention (AUR) after transperineal template-guided mapping biopsy (TTMB).Materials and Methods: We retrospectively reviewed the records of 459 patients who had undergone TTMB between May 2017 and July 2020. Overall complications after TTMB were analyzed and categorized according to the Clavien-Dindo classification. Factors that were likely to affect AUR were analyzed using a logistic regression model.Results: Overall complications after TTMB were observed in 95 of the 459 patients (20.7%), of which AUR was the most commonly reported (17.4%, n=80), followed by hematuria (3.1%, n=14). Hematuria in one patient was categorized as Clavien-Dindo grade IIIa. All remaining complications were Clavien-Dindo grade I. In the multivariate regression model, age ≥65 (odds ratio, 2.44; 95% confidence interval [CI], 1.42–4.17; p=0.001), prostate volume ≥30 mL (odds ratio, 3.72; 95% CI, 1.19–11.62; p
