Current Status of Transurethral Prostatectomy: A Korean Multicenter Study

ABSTRACT

PURPOSE: We aimed to verify the current status of transurethral resection of the prostate (TURP) in Korea. MATERIALS AND METHODS: The medical records of 1,341 men who underwent TURP in 9 Korean medical centers between 2004 and 2008 were reviewed. The patients were divided into two groups according to time periods: 2004-2005 (group 1) and 2006-2008 (group 2). To verify differences in the two patient groups, age, prostate volume, indications for TURP, preoperative International Prostate Symptom Score (IPSS), and resected tissue weight were evaluated. RESULTS: The mean age of the patients was 71.2 years and the mean IPSS was 22.7. The patients' characteristics were not significantly different between the two groups. The annual cases of TURP increased over the study period. The proportion of lower urinary tract symptoms (LUTS) as an indication for TURP increased up to 58.3% in group 2 compared with 51.6% in group 1 (p=0.019). However, the proportion of patients who presented with acute urinary retention decreased from 35.5% to 30.3% with marginal statistical significance (p=0.051). Other indications such as hematuria, bladder stone, recurrent urinary tract infection, and hydronephrosis were not significantly different between the groups. The mean resected weights of the prostate were similar (17.5 g in group 1 and 18.3 g in group 2, respectively; p>0.05). CONCLUSIONS: TURP has been steadily performed in patients with benign prostatic hyperplasia and it is expected to remain constant. LUTS was the most common indication for TURP in recent years.
