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 consecutive patients who underwent sPCNL were retrospectively analyzed. Preoperative computed tomography images were reviewed. The S-ReSC score was a

AIM: To compare the prostate volume, as measured by transrectal ultrasonography (TRUS) and by MRI, with that of the actual prostate volume measured after a radical prostatectomy (RRP). MATERIALS AND METHODS: This prospective study included 21 patients who had undergone RRP. TRUS prostate volumes were calculated using the prolate ellipsoid volume formula, with the anteroposterior diameter measured from axial (TRUS-V1) and mid-sagittal images (TRUS-V2). Two prolate ellipsoid volumes (MRI-EV1 and M

Our results demonstrated that the operative learning curve plateau is reached after about 25 cases. We propose that a more appropriate parameter for estimating the operative learning curve is enucleation ratio efficacy, rather than enucleation efficacy.

We constructed and validated nomograms to predict SFR after SWL. To the best of our knowledge, these are the first graphical nomograms to be modeled with CT information. These may be useful for patient counseling and treatment decision-making.

INTRODUCTION: We performed a prospective, randomized study to examine the efficacies of levofloxacin and doxazosin alone and as a combination therapy in patients with National Institutes of Health (NIH) category III chronic prostatitis/chronic pelvic pain syndrome. PATIENTS AND METHODS: Men with a NIH diagnosis of category III chronic prostatitis/chronic pelvic pain syndrome and who had experienced pelvic pain for more than 3 months during the last 6 months were enrolled. All patients underwent

SUPER-GUC is a study platform for comparative outcome, quality-of-life, and translational (genetics, biomarkers) research for genitourinary cancer.

OBJECTIVES: To develop and evaluate nomograms to predict the pathological stage of clinically localized prostate cancer after radical prostatectomy in Korean men. METHODS: We reviewed the medical records of 2041 patients who had clinical stages T1c-T3a prostate cancer and were treated solely with radical prostatectomy at two hospitals. Logistic regressions were carried out to predict organ-confined disease, extraprostatic extension, seminal vesicle invasion, and lymph node metastasis using preop

One-step posterior reconstruction did not significantly shorten time to complete continence recovery. However, it seemed to have a marginal benefit on early recovery of social continence.

OBJECTIVE: To provide detailed characteristics of asymptomatic microscopic hematuria, as well as to identify the significant predictors of detecting underlying diseases of asymptomatic microscopic hematuria, by evaluating a large Korean population. METHODS: We obtained data from healthy adults over the age of 20 years who underwent the health-screening program from 2005 to 2010 at Seoul National University Bundang Hospital, resulting in 56,632 participants included in the analysis. Patients who

BACKGROUND AND PURPOSE: Severe postoperative bleeding after radical prostatectomy is a rare, but serious, complication. Massive postoperative bleeding causing hemodynamic instability necessitates open surgical exploration and can be associated with considerable morbidity. We report our experience with minimally invasive management of postprostatectomy hemorrhage via transarterial embolization (TAE). PATIENTS AND METHODS: From July 2006 to April 2009, men with severe immediate postoperative bleed
