치골후전립선적출술과 경요도전립선절제술의 치료 효과 - 차이 유무 및 그 이유에 대한 검토

Purpose: To retrospectively compare the results of a retropubic prostatectomy to that of a transurethral resection of the prostate (TURP) and investigated the causes of the different results.<BR> Materials and Methods: Fifteen patients were retrospectively included in each group, who were operated on by one experienced urologist. The direct outcomes, such as max flow rate (Qmax), prostate and transitional zone (TZ) volumes, proximal prostatic urethral width, and transrectal ultrasonography (TRUS) and urethroscopic findings, and intermediate outcomes, such as International Prostate Symptom Score (IPSS) and Quality of Life (QOL), were measured both before and after the operation. The adenoma resection rates (resected volume/preoperative TZ volume) were compared and its value investigated.<BR> Results: In the retropubic prostatectomy group, the IPSS and QOL decreased from 24.5±4.9 and 4.3±1.0 to 4.8±3.3 and 1.2±0.9, respectively, and the Qmax increased from 6.3±2.6 to 23.1±6.6㎖/sec. In the TURP group, the IPSS and QOL decreased from 23.5±6.0 and 3.9±1.3 to 12.0±9.0 and 1.6±1.4, respectively, and the Qmax increased from 8.2±3.6 to 16.6±7.7㎖/sec. The adenoma resection rate and proximal prostatic urethra width were 0.98 (mean, max＝1.63, min＝0.30) and 8.5±3.7mm, respectively, in the retropubic prostatectomy group, compared with 0.61(mean, max＝1.41, min＝0.35), 4.3±1.9mm in the TURP group. In the retropubic prostatectomy group, the proximal prostatic urethra was wider and more symmetrical and its surface more even (p＜0.05).<BR> Conclusions: A retropubic prostatectomy achieved a better result than the TURP, because the proximal prostatic urethra was more symmetrical and its surface more even.
