PURPOSE: We determined the effect of a urethral catheter on abdominal leak point pressure in men and women with intrinsic sphincter deficiency.
MATERIALS AND METHODS: A total of 21 consecutive men treated with prostatectomy and 19 women with intrinsic sphincter deficiency underwent abdominal leak point pressure measurements with a rectal catheter before and after removal of a 10F urethral catheter.
RESULTS: Of the 19 women 2 had leakage only when the urethral catheter was removed, while 17 had excellent correlation between abdominal leak point pressures before and after catheter removal (r = 0.83). In contrast, 10 of 21 men had leakage only when the urethral catheter was removed and 11 had weak correlation between abdominal leak point pressures before and after catheter removal (r = 0.46).
CONCLUSIONS: An indwelling 10F urethral catheter is much more likely to invalidate abdominal leak point pressure measurement in men than in women with intrinsic sphincter deficiency.
