A prospective randomized study comparing modified Burch retropubic urethropexy and suburethral sling for treatment of genuine stress incontinence with low-pressure urethra.
OBJECTIVE
The aim of this study was to compare a modified Burch procedure with a suburethral sling for the treatment of stress incontinence complicated by a low-pressure urethra.


METHODS
Thirty-six women with stress incontinence, low-pressure urethra, and urethral hypermobility (straining cotton swab angle >/=30 degrees ) were randomly assigned to undergo either a modified Burch procedure (n = 19) or a suburethral sling (n = 17). Objective and subjective cure rates at 3 months after the operation were the primary outcome measures. Comparisons of group means were performed with the Student t test for independent groups, and proportions were compared with the Fisher exact test.


RESULTS
After the operation the 2 groups had statistically similar cure rates and voiding function. Urethral closure pressure, pressure transmission ratios, and maximum detrusor pressure during voiding were significantly higher in the sling group.


CONCLUSIONS
At 3 months there were no clinically significant differences between the groups treated with suburethral sling and modified Burch procedures.
