PURPOSE To evaluate the efficacy and safety of the ureteroscopic management of ureteral stones immediately after a first colic attack. MATERIALS AND METHODS We retrospectively analyzed the data of 226 patients with obstructive ureteral stones who underwent ureteroscopy with stone retrieval. The 67 patients in group A underwent ureteroscopy within 48 hours(More)
BACKGROUND To evaluate the effects of hyaluronic acid (HA) and carboxymethylcellulose (CMC) on the recurrence of urethral stricture after treatment with endoscopic internal urethrotomy (EIU). METHODS A total of 120 patients underwent EIU for urethral stricture. Recruited patients were randomly divided into two groups: group A and B. Patients in group A(More)
PURPOSE The aim of this study was to evaluate possible predictive variables for the outcome of shock wave lithotripsy (SWL) of renal stones in a single center. MATERIALS AND METHODS Between March 2008 and March 2010, a retrospective review was performed of 115 patients who underwent SWL for solitary renal stones. The patients' characteristics and stone(More)
PURPOSE Previously we reported that the histone deacetylase inhibitor trichostatin A (Sigma®) synergistically potentiates the antitumor effects of cisplatin in human bladder cancer cells. In the current study we explored the synergistic interaction between trichostatin A and gemcitabine (Novartis Korea, Seoul, Korea), the other mainstay chemotherapeutic(More)

PURPOSE The purpose of our study was to investigate the safety and efficacy of the suprapubic arch (SPARC) sling operation and the transobturator tape (MONARC) sling operation according to body mass index (BMI). MATERIALS AND METHODS Between January 1, 2004, and July 12, 2009, a retrospective clinical trial was performed with 284 patients treated by the(More)
PURPOSE To evaluate the effect of hyaluronic acid (HA) and carboxymethylcellulose (CMC) instillation after transurethral resection of the prostate (TURP) on preventing urethral stricture. PATIENTS AND METHODS A total of 180 patients underwent TURP for benign prostatic hyperplasia. Recruited patients were randomly divided into two groups: Groups A and B.(More)
PURPOSE Most patients, even some urologists, assume that prostate volume is the most important prognostic factor for lower urinary tract symptoms (LUTS). In some cases, however, prostatic inflammation is a more important factor in LUTS than is prostate volume. For this reason, comparison of the impact on LUTS of inflammation and prostate volume is an(More)
PURPOSE Percutaneous nephrolithotomy (PCNL) is the procedure of choice for treating large renal stones. Pneumatic lithotripsy (Lithoclast®) is effective regardless of the stones' composition, and ultrasonic lithotripsy allows the aspiration of small debris during lithotripsy. We investigated the efficacy and safety of PCNL via Lithoclast® alone or combined(More)
For the evaluation of the kidney impairment, serum creatinine concentrations or glomerular filtration rates are mainly used, and the conditions of solitary or transplanted kidney and chronic dialysis are also taken into the considerations. Some symptoms and signs of the chronic renal disability in spite of adequate treatment add one additional grade. For(More)
