Utilization of surgical procedures and racial disparity in the treatment of urinary incontinence after prostatectomy

Abstract

AIMS: To analyze the rates of incontinence procedures after radical prostatectomy, and define the variables associated with them. METHODS: We conducted an IRB approved retrospective review of patients with prostate cancer who underwent radical prostatectomy at a single institute from January 1998 to December 2012. Logistic regression and time to event analyses were performed to ascertain variables associated with receipt of incontinence procedure after prostatectomy. RESULTS: Four thousand four hundred one men underwent radical prostatectomy (69.8% open, 30.1% laparoscopic or robotic) of whom 74.3% were white Caucasian and 22.1% were African-American. Overall, 165 (3.7%) patients underwent a total of 191 procedures for male urethral sling or artificial urinary sphincter placement. African-American men received fewer incontinence procedures than white Caucasian men (2.1% versus 4.3%, P = 0.001); and with a longer delay after prostatectomy than white Caucasian men (28.3 months versus 19.9 months, P = 0.029). Men who had a laparoscopic or robotic prostatectomy received an incontinence procedure earlier than men who had an open prostatectomy (17.6 months versus 24.4 months, P = 0.0001). On multivariate analysis, age at prostatectomy, diagnosis of incontinence, and race were independently associated with receiving an incontinence procedure. CONCLUSIONS: The overall rate of incontinence surgery after radical prostatectomy is low at 3.7%. African-American men receive incontinence procedures at a lower rate and with a longer delay after prostatectomy than white Caucasian men. Further studies are needed to define the reasons for this racial disparity in urinary incontinence surgery in the prostate cancer survivor. Neurourol.
