The safety and efficacy of laparoendoscopic single-site surgery (LESS) for renal cell carcinoma (RCC) have not been clearly demonstrated. We aimed to present preliminary data from a prospective randomized controlled trial of LESS versus conventional laparoscopic radical nephrectomy for localized RCC. Patients with cT1-2 RCC were randomized to LESS (n = 17)(More)
PURPOSE To evaluate risk factors for deterioration of lower urinary tract symptoms (LUTS) in elderly men in a community-based, prospective longitudinal cohort study. METHODS In a suburban area in Korea, 1,514 subjects aged ≥45 years were randomly selected by systematic sampling. A total of 918 elderly subjects were enrolled in this in-depth clinical study(More)
We investigated the influence of positive surgical margins (PSMs) and their locations on biochemical recurrence (BCR) according to risk stratification and surgical modality. A total of 1,874 post-radical-prostatectomy (RP) patients of pT2–T3a between 2000 and 2010 at three tertiary centers, and who did not receive neoadjuvant/adjuvant therapy, were included(More)
OBJECTIVE To evaluate the prognosis of patients with renal cell carcinoma (RCC) by nutritional status defined by body mass index (BMI), serum albumin and cholesterol. PATIENTS AND METHODS This study retrospectively enrolled 1437 patients who underwent radical nephrectomy (932) or partial nephrectomy (505) for RCC. We assigned nutritional status according(More)
PURPOSE According to previous studies, the prevalence of premature ejaculation (PE) in Korea ranges from 11.3% to 33%. However, the actual practice patterns in managing patients with PE is not well known. In this study, we have endeavored to determine how contemporary urologists in Korea manage patients with PE.

PURPOSE To evaluate how much the improvement of lower urinary tract symptoms (LUTS) affects sexual function and which storage symptoms or voiding symptoms have the greatest effect on sexual function. MATERIALS AND METHODS A total of 187 patients were enrolled in this study. Patients were randomly assigned to receive either tamsulosin 0.2 mg (group A) or(More)
OBJECTIVE To examine the correlation between estimated intravaginal ejaculatory latency time (eIELT) and stopwatch-measured intravaginal ejaculatory latency time (sIELT), and to assess the clinical utility of eIELT in identifying men more likely to have lifelong premature ejaculation (PE). METHODS A prospective, observational, multicenter study was(More)
PURPOSE The goal of this study was to investigate the long-term efficacy and safety of a mixture of polymethyl methacrylate (PMMA) and cross-linked dextran Lipen-10® used for penile augmentation under the physical impact generated during sexual intercourse. MATERIALS AND METHODS From March 2010 to October 2011, a total of 20 patients with a mean age of 44(More)
The long-term mortality risk from prostate cancer increases in lymph node (LN) positive patients. This study was done to assess the effect of lymph node Gleason score (LNGS) on prognosis in patients with LN-positive prostate cancer. Among the 1,415 patients who received pelvic lymph node dissection (PLND), 117 (8.4%) patients had a positive LN. The PGS of(More)
PURPOSE The aim of the present study was to evaluate the effects of low-dose tamsulosin on sexual function in patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia. MATERIALS AND METHODS A total of 138 male LUTS patients aged more than 50 years with an International Prostate Symptom Score (IPSS) ≥8 were enrolled in(More)
