OBJECTIVES To compare the oncological outcomes of robot-assisted laparoscopic radical prostatectomy with those of open radical prostatectomy in contemporary Korean prostate cancer patients. METHODS From a group of 1172 patients consisting of 592 (50.5%) robot-assisted laparoscopic radical prostatectomy and 580 (49.5%) open radical prostatectomy cases(More)
PURPOSE Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. MATERIALS AND METHODS From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs(More)
PURPOSE The purpose of this study is to set guidelines for the management of renal angiomyolipoma (AML), clinical prognosis according to tumor size, in association with tuberous sclerosis complex (TSC), multiplicity, radiographic finding, and treatment modality. MATERIALS AND METHODS Between March 1998 and October 2008, 129 out of 254 patients with AML(More)
PURPOSE We analyzed the pathological outcomes of candidates for active surveillance according to tumor lesion diameter on diffusion weighted magnetic resonance imaging. MATERIALS AND METHODS We retrospectively analyzed 188 candidates for active surveillance who had undergone diffusion weighted magnetic resonance imaging before radical prostatectomy(More)
The background of this study is to compare prospectively the oncological and functional results of open radical prostatectomy (OP) and robotic prostatectomy (RP) from the experience of a single surgeon. Between June 2002 and June 2007, 422 patients underwent radical prostatectomy (OP 199, RP 223). We divided OP patients into 89 early cases (OP-I) and 110(More)
BACKGROUND Trifecta achievement in partial nephrectomy (PN) is defined as the combination of warm ischemia time ≤ 20 min, negative surgical margins, and no surgical complications. OBJECTIVE To compare trifecta achievement between robotic, laparoendoscopic, single-site (R-LESS) PN and multiport robotic PN (RPN). DESIGN, SETTING, AND PARTICIPANTS Data(More)
BACKGROUND The purpose of this article was to determine the impact of time to undetectable prostate-specific antigen (PSA) for predicting biochemical recurrence (BCR) in patients with a positive surgical margin (PSM) following radical prostatectomy (RP). A PSM is an independent predictor of BCR; however, not all patients develop BCR later on. METHODS A(More)
OBJECTIVE To evaluate the effect of the prostatic urethral angle (PUA) on the peak flow rate (Qmax) and urinary symptoms in the clinical setting. MATERIALS AND METHODS The records were obtained from a prospectively maintained database for first-visit men with lower urinary tract symptoms. Uroflowmetric measurements, postvoid residual urine volume, and(More)
PURPOSE To evaluate the predictive performance of various parameters derived from volume-adjusted prostate-specific antigen (PSA) values in detecting prostate cancer (PCa) and high-grade (Gleason score≥7) PCa according to treatment with a 5α-reductase inhibitor (5ARI). METHODS The results of 3,520 prostate biopsies performed between May 2006 and January(More)
