Prevalence of "uncomplicated" and "complicated" stress urinary incontinence in Argentinian women: Assessing the role of the urodynamic study.

OBJECTIVE

To determine the percentage of Argentinian patients with "uncomplicated" and "complicated" stress urinary incontinence (SUI) in whom preoperative urodynamics study (UDS) was performed. The secondary objective of the study was to evaluate differences between clinical observation and urodynamics in both groups of women.

METHODS

A retrospective study of women with IOE derivatives for UDS prior to surgical treatment is performed. The analyzed patients were classified in complicated and not complicated according to the criteria of the study VALUE. The prevalence of different urodynamics observations was assessed in patients with complicated and uncomplicated SUI.

RESULTS

We studied 792 patients with SUI derivatives for UDS. Of the patients studied, 313 (39.5%) were considered as uncomplicated SUI and 479 (60.5%) as complicated SUI. The Urodynamics observation was considered different from the clinical data in 415/792 (52.4%), although in greater proportion in SUI complicated (59.9% vs. 40.9%, p < 0.001). There was a higher incidence of voiding dysfunction in patients with complicated SUI (32.4% vs. 14.7%, p < 0,001).

CONCLUSIONS

Patients with uncomplicated SUI represent 39% of patients studied with SUI. The differences between clinical evaluation and urodynamics are higher in patients with complicated SUI contributing new information in 60% of the cases.
