Oncologic and Functional Outcomes after Partial Nephrectomy Versus Radical Nephrectomy in T1b Renal Cell Carcinoma: A Multicenter, Matched Case-Control Study in Korean Patients.

Purpose: The study was to compare the oncologic and functional outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for pathologically proven T1b renal cell carcinoma using pair-matched groups.

Materials And Methods: We reviewed our prospectively maintained database for RN and PN in T1b renal tumors surgically treated between 1999 and 2011 at five institutions in Korea. Of 611 patients treated with PN or RN for a solitary and NX/N0 M0 renal mass (4-7 cm), 577 (PN, 100; RN, 477) patients with pathologically confirmed pT1b remained for analysis.

Effects of coenzyme Q10 on bladder dysfunction induced by chronic bladder ischemia in a rat model.

Purpose: We investigated the protective effects of coenzyme Q10 on bladder dysfunction in a rat model of atherosclerosis induced chronic bladder ischemia.

Materials And Methods: A total of 24 male Sprague-Dawley® rats at age 16 weeks were divided into 4 groups of 6 each, including group 1--untreated, sham operated rats, group 2--coenzyme Q10 treated, sham operated rats, group 3--untreated rats with chronic bladder ischemia and group 4--coenzyme Q10 treated rats with chronic bladder ischemia. Groups 3 and 4 received an endothelial injury to the iliac arteries and were fed a 2% cholesterol diet for 8 weeks.

An Organic Intravesical Foreign Body Caused by Penetrating Trauma that was Missed during Initial Management.

We report a case of an intravesical foreign body that was incompletely removed endoscopically and that defied diagnosis with current diagnostic tools. A 65-year-old man visited Korea University Anam Hospital complaining of dysuria and a sensation of residual urine. His medical history included an intravesical foreign body caused by penetrating trauma, and he had undergone endoscopic removal of foreign bodies 1 year previously.

Initial experience of robot-assisted radical cystectomy with total intracorporeal urinary diversion: comparison with extracorporeal method.

Purpose: To report our surgical technique and initial experience with robot-assisted laparoscopic radical cystectomy (RARC) with total intracorporeal urinary diversion compared with an extracorporeal method.

Subjects And Methods: In total, 42 patients underwent RARC by a single surgeon at our institute for clinically localized bladder cancer. Among these, 4 patients underwent RARC with complete intracorporeal urinary diversion.

The efficacy of in-and-out catheterization as a way of trial without catheterization strategy for treatment of acute urinary retention induced by benign prostate hyperplasia: variables predicting success outcome.

Aim: To evaluate the efficacy and proper use of in-and-out catheterization as a strategy for trial without catheterization (TWOC) for treatment of acute urinary retention (AUR).

Methods: Retrospective analysis of 515 patients who visited the emergency room with AUR from January 2004 to December 2008 was conducted. Patients were segregated to one of two groups, depending on management of AUR (in-and-out catheterization at one time: Group 1 or indwelling catheter: Group 2).

Clinical Implications of Residual Urine in Korean Benign Prostatic Hyperplasia (BPH) Patients: A Prognostic Factor for BPH-Related Clinical Events.

Purpose: Although post-void residual urine (PVR) is frequently utilized clinically in patients with benign prostatic hyperplasia (BPH), mainly because of its procedural simplicity, its role as a clinical prognostic factor, predictive of treatment goals, is still under much dispute. We investigated the predictive value of PVR for BPH-related clinical events including surgery, acute urinary retention (AUR), and admission following urinary tract infection (UTI).

Methods: From January to June of 2006, patients over 50 years of age who were diagnosed with BPH for the first time at the outpatient clinic and were then treated for at least 3 years with medications were enrolled in this study.

Single positive core prostate cancer in a 12-core transrectal biopsy scheme: clinicopathological implications compared with multifocal counterpart.

Purpose: The incidence of single positive core prostate cancer at the time of biopsy appears to be increasing in the prostate-specific antigen (PSA) era. To determine the clinical implication of this disease, we analyzed surgical and pathological characteristics in comparison with multiple positive core disease.

Materials And Methods: Among 108 consecutive patients who underwent robotic radical prostatectomy following a diagnosis of prostate cancer based on a 12-core transrectal biopsy performed by the same method in a single institute, outcomes from 26 patients (Group 1) diagnosed on the basis of a single positive biopsy core and from 82 patients (Group 2) with multiple positive biopsy cores were analyzed.
