[De novo stress urinary incontinence following sacral colpopexy]

To evaluate the risk of occurrence of de novo stress urinary incontinence (SUI) after sacral colpopexy (SCP).

In all, 57 women with no concomitant or occult SUI, had a SCP for urogenital prolapse between January 2006 and October 2009. Some data from their medical charts (age, body mass index, past medical history, maximum urethral closure pressure, bladder neck hypermobility) were reviewed retrospectively and statistically analyzed to assess the association between these factors and de novo SUI.

With a median follow-up of 16 months, four patients (7.3%) developed de novo SUI 1 year postoperative and which required the wearing of pads defensively, three of which were significantly improved after pelviperineal rehabilitation, however only one patient: 1.8% required the establishment of a sub-urethral tape 8 months after the surgical correction of prolapse. No statistically significant association has been established despite a P<0.01 between the sphincter deficiency (SD) and de novo SUI because of a sample too small inferior to five, however predictive values for PPV and NPV, the MUCP was 43 and 2.2%.

The results of this study were consistent with the literature data, the risk to our patients to develop de novo SUI requiring secondly anti-incontinence procedure was lower: 7.3% but could become more important: 43% if preoperative SD. Patients should always be informed before surgery as it cannot be predicted.
