Detrusor activity and outflow resistance in stress incontinence.
The successful treatment of urinary stress incontinence in females dependends on a careful study of urodynamics. Pre-operative measurements of urine flow rate and residual urine can be useful only in differentiating compensated from deconpensated micturition. However, some selected problems require a more detailed investigation. Therefore synchronous cine/pressure/flow/cystourethrographic studies were performed in 20 stress-incontinent women. In some of them, an increased outflow resistance was thus demonstrated. Any type of operation for stress incontinence which raises outflow resistance must be avoided in these cases. Long-distanced urethrocystopexy which permits to avoid an unwanted increase of outflow resistance with following retention of urine should be preferred.
