PURPOSE To investigate the difference in rectal complications rate following prostate low dose rate (LDR) brachytherapy based on prostate-rectum distance and prostate longitudinal length among early prostate cancer patients. MATERIALS AND METHODS From March 2008 to February 2013, 245 prostate cancer patients with a Gleason score ≤7 were treated with 125-I(More)
Detrusor underactivity (DU) or underactive bladder is a common cause of lower urinary tract symptoms (LUTS), but it is still poorly understood and underresearched. Although there has been a proposed definition by International Continence Society in 2002, no widely accepted diagnostic criteria have been established for this entity in clinical practice.(More)
PURPOSE The aim of this study was to find risk factors for early recurrence (ER) and early death (ED) after liver resection for colorectal cancer liver metastasis (CRCLM). METHODS Between May 1990 and December 2011, 279 patients underwent liver resection for CRCLM at Korea University Medical Center. They were assigned to group ER (recurrence within 6(More)
To investigate the efficacy of tamsulosin monotherapy and tamsulosin with low-dose sildenafil combination therapy on lower urinary tract symptoms (LUTS) following low-dose-rate (LDR) brachytherapy in early prostate cancer patients. From March 2008 to June 2014, of the 212 prostate cancer patients with a Gleason score ≤7 who received LDR brachytherapy, 80(More)
Introduction and Aims. Congenital absence of the vas deferens is an uncommon anomaly and this clinical condition is responsible for up to 1-2% of male infertility. It can be either unilateral or bilateral and the associated anomalies include cryptorchidism, seminal vesicles and ejaculatory ducts anomalies, and renal anomalies such as renal agenesis. We(More)
AIM To evaluate the effects of prostatic apex shape variations on positive apical margin rate (PAM) after radical prostatectomy (RP) by undertaking a comparative study of robot-assisted laparoscopic radical prostatectomy (RALP) versus open radical prostatectomy (ORP). METHODS A total 3,324 cases of RP (1,004 ORP and, 2,320 RALP) from January 2004 to March(More)
To determine an optimal invasive intervention for renal colic patients during pregnancy after conservative treatments have been found to be unhelpful. Among the available invasive interventions, we investigated the reliability of a ureteral stent insertion, which is considered the least invasive intervention during pregnancy. Between June 2006 and February(More)
Renal cell carcinoma (RCC) with Von Hippel-Lindau (VHL) syndrome is associated with multiple recurrences and a young age at diagnosis. Therefore the primary goal of treatment is to stabilize the disease, minimizing the surgical resection and preserving the renal function in the patients with VHL who have developing RCC nodules after initial treatment.
