Urethral Strictures Associated with Early Urinary Retention

Radical prostatectomy patients experiencing early urinary retention are at a greater risk for the development of urethral strictures

WEDNESDAY, Sept. 19 (HealthDay News) -- Men who develop early urinary retention after radical prostatectomy are more likely to develop a symptomatic urethral stricture, according to a prospective database report published in the August issue of Urology.

David P. Wood, M.D., of the University of Michigan Health System in Ann Arbor, and colleagues analyzed records of 1,289 patients who had undergone radical prostatectomy between 1998 and 2004. Early urinary retention was defined as retention that occurred within seven days of initial catheter removal.

Urethral strictures developed in 36.4 percent of the men who developed early urinary retention as compared to 9 percent of men who did not develop early urinary retention. Among patients from both groups who developed stricture formation, men who had early urinary retention developed strictures more quickly than men who had not (1.6 months versus 3 months). They also developed bladder neck contractures more often than more distal urethral strictures (94 percent versus 68 percent).

"Although only 1.2 percent of our study population developed both early urinary retention and symptomatic urethral strictures, the association between early urinary retention and urethral stricture formation is important to remember when caring for post-radical prostatectomy patients," the authors conclude.
