Urinary diversion practice patterns among certifying American urologists

Abstract

Purpose: We investigated trends in urinary diversion use and surgeon characteristics in the performance of incontinent and continent urinary diversion using American Board of Urology data.

Materials and methods: Annualized case log data for urinary diversion were obtained from the American Board of Urology for urologists who certified or recertified from 2002 to 2010. We evaluated the association between surgeon characteristics and the performance of any urinary diversion or the type of urinary diversion.

Results: Of the 5,096 certifying or recertifying urologist case logs examined 1,868 (37%) urologists performed any urinary diversion. The median number of urinary diversions was 4 per year (IQR 2, 6) and 222 urologists (4%) performed 10 or more per year. On multivariate analysis younger urologists, those self-identified as oncologists or female urologists, those who certified in more recent years and those in larger practice areas or outside the Northeast region of the United States were more likely to perform any urinary diversion. Only 9% of the total cohort (471 urologists) performed any continent urinary diversion. The likelihood of performing any continent urinary diversion increased with the number of urinary diversions (p <0.0001). As urinary diversion volume increased, the proportion representing continent urinary diversion also increased (p <0.0005). Surgeons in private practice settings and those in the Northeast were less likely to perform continent urinary diversion.

Conclusions: Few urologists perform any urinary diversion. Continent urinary diversion is most frequently done by high volume surgeons. The type of urinary diversion that a patient receives may depend in part on surgeon characteristics.
