Purpose:
We verified if the necessity of long-term catheterization after a pubovaginal rectus fascial sling procedure can be predicted by preoperatively determined bladder contraction strength.
Materials And Methods:
We analyzed the files of 58 consecutive nonneurogenic women who underwent a sling procedure for severe or refractory stress urinary incontinence. Preoperative urodynamic measurements in these patients were re-analyzed using the power factor WF and the bladder contractility index as bladder contraction strength parameters. Catheterization was considered necessary if the patient self-catheterized at least once daily.
Results:
One patient was lost to followup. Three and 6 months after surgery 24 (42%) of 57 and 18 (33%) of 54 patients were on catheterization. On average patients who were not on catheterization had a stronger bladder but the results were not consistently statistically significant.
Conclusions:
A trend toward higher bladder contraction strength in patients not on catheterization was found. However, preoperative urodynamic examination can only poorly predict the necessity of long-term catheterization after sling surgery.

In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
