PURPOSE To identify the prevalence and clinical features of detrusor underactivity (DU) in elderly men and women presenting with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS We reviewed 1,179 patients aged over 65 years who had undergone a urodynamic study for LUTS with no neurological or anatomical conditions. DU was defined as a bladder(More)
OBJECTIVE We investigated potential associations between rheumatoid arthritis (RA) and interferon regulatory factor 5 (IRF5) polymorphisms in a metaanalysis. METHODS This metaanalysis included 5 case-control studies, which provided a total of 6582 RA cases and 5375 controls. Odds ratios (OR) were employed to evaluate the risk of RA according to the 4(More)
Few studies have been conducted on the serial evaluation of predictors for recovery of urinary continence (RC) after radical prostatectomy (RP) among same cohort. We developed and validated nomograms to predict immediate (≤1), early (≤3), and late (≤12 months) RC from a contemporary series and compared each nomogram with regard to the significance of(More)
PURPOSE To evaluate whether the risk of prostate cancer was different according to the pattern of fluctuation in prostate-specific antigen (PSA) levels in patients undergoing repeat transrectal ultrasound-guided prostate biopsy (TRUS-Bx). METHODS From March 2003 to December 2012, 492 patients underwent repeat TRUS-Bx. The patients were stratified into 3(More)
UNLABELLED What's known on the subject? and What does the study add? Previously, it has been reported that PSA may not perform as accurately as PSA density (PSAD) in predicting outcomes after radical prostatectomy among patients with Gleason score 6 prostate cancer. However, there have been few studies comparing the usefulness of PSA and PSAD in predicting(More)
BACKGROUND The presenting features and clinical course of biomass smoke induced bronchial anthracofibrosis (BAF) are not well known. PATIENTS AND METHODS 333 patients who had a history of long-term exposure to biomass smoke, having BAF confirmed by a bronchoscopy from January 1998 to December 2004, were included in this study. The clinical features,(More)
OBJECTIVES Currently, no standardized method is available to predict success rate after percutaneous nephrolithotomy. We devised and validated the Seoul National University Renal Stone Complexity (S-ReSC) scoring system for predicting the stone-free rate after single-tract percutaneous nephrolithotomy (sPCNL). PATIENTS AND METHODS The data of 155(More)
The Seoul National University Renal Stone Complexity (S-ReSC) score is a well-validated tool for the prediction of stone-free rate (SFR) after percutaneous nephrolithotomy. We modified the S-ReSC score system for application to retrograde intrarenal surgery (RIRS) and evaluated this score. A total of 88 patients who underwent RIRS from 2011 to 2013 were(More)
PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as an alternative treatment for the management of small renal masses. This study was designed to investigate parameters that predict perioperative outcomes during RPN. MATERIALS AND METHODS We retrospectively reviewed the medical records of 113 patients who underwent RPN between September 2008(More)
Conventional articulating instruments for laparoendoscopic single-site (LESS) surgery have three major drawbacks: Weak articulating force, internal and external crowding, and mirror imaging and motion. The RoboHand™ is a recently developed novel articulating instrument. The goal of its development was to minimize the abovementioned three major drawbacks. In(More)
