Intrapelvic urethral XXXX . A comparison of three techniques.

@entity235 @entity384 @entity254 @entity5450 @entity3041 @entity292 @entity2885 @entity850
Three intrapelvic urethral @entity254 techniques were performed on 12 mature male @entity235 to compare the degree of @entity850 . The intrapelvic urethra was transected 1 cm caudal to the prostate, and @entity254 was performed using either suturing of the urethra over an indwelling catheter, suturing of the urethra without an indwelling catheter, or apposition of the urethra without sutures over an indwelling catheter. Postoperatively, the @entity235 were evaluated using clinical urination patterns, biochemical tests, radiography, and pathology. Three of four suture-catheter @entity235 and one of four catheter-only @entity235 had normal urinary patterns. Stricture (25-84%) with @entity384 or @entity292 tracts was visible on retrograde, positive contrast urethrograms of 3 of 12 intact @entity235 20 weeks after surgery, and on all 12 excised lower urinary tracts. Suture-catheter @entity235 subjectively had the least amount of @entity850 . All eight @entity235 (1 suture-catheter @entity235 , 4 suture-only @entity235 , and 3 catheter-only @entity235 ) with severe @entity850 (greater than 60% lumen diameter reduction) had histopathologic signs of chronic, inflammatory @entity5450 , including four with chronic, ascending lymphocytic @entity2885 . Hydroureter and @entity3041 developed in two catheter-only @entity235 . Complete urethral transection resulted in some degree of @entity850 , regardless of technique used for @entity254 . Urethral @entity254 over an indwelling catheter appeared to result in a lesser degree of @entity850 and clinical and histopathologic derangement.
