Incontinence & Female Urology & Neurourology(구연) (E-177) 로봇 이용 전립선 절제술 후 요실금을 예측하기 위한 방광조영술에서의 새로운 파라미터: 기존의 방광조영술에서 증명된 술후 요실금 예측 변수와의 비교 연구 영남대학교 의과대학 비뇨의학교실 김영욱, 이권수, 최재영, 고영휘, 문기학. 정희창. 송필현 Purpose Postprostatectomy incontinence (PPI) is one of the significant surgical complications after radical prostatectomy (RP) and can influence patient’ quality of life (QoL). Several studies have reported that postoperative cystography, as a simple method and performed routinely to check urinary leakage after surgery, is associated with prediction of PPI. However, few studies have reported postoperative cystography for predictor of PPI in Korea. Therefore, we retrospectively investigated whether the findings on postoperative cystography could predict early and long-term recovery of incontinence after RP. Materials and Methods After we retrospectively reviewed a total of 147 patients who underwent robot-assisted radical prostatectomy (RARP) for localized prostate cancer in our institution between January 2017 to June 2018, one hundred and seven patients were included in this study. Postoperative cystography was performed routinely on 7 day after RARP. The bladder neck to pubic symphysis (BNPS) ratio, the bladder neck angle, and the ratio between the anteroposterior lengths of bladder and the lengths from posterior to bladder neck (AP-BN) were evaluated. Continence was defined as the cessation of pad use (zero-pad). The association between these variables and urinary incontinence was analyzed. Results Continence restoration rate for all patients at 1, 3, 6, and 12 months after RARP were 38.7%, 71.5%, 84.1%, and 98.4%, respectively. In univariable analysis, the BNPS ratio, bladder neck angle, and the ratio of AP-BN were significantly associated with urinary incontinence at 1, 6, and 12 months (p<0.001). However, the bladder neck angle and the ratio of AP-BN were significantly associated with incontinence at 1 and 12 months in multivariable analysis (p=0.023 and 0.048, respectively). Conclusions A narrow bladder neck angle and posterior location of bladder neck defined by AP-BN ratio on cystography correlate with continence rate and may predict the PPI after RARP. keywords : Urinary Incontinence, Prostatectomy, Cystography
