Comparative data from history,clinical examination and urodynamics in patients with genuine stress urinary incontinence and recurrent stress urinary incontinence after surgery

In this study 272 patients with genuine stress urinary incontinence (GSUI) were initially considered. Of these, 247 were divided into three groups based on: positive history for GSUI (group 1); positive history and clinical examination for GSUI (group 2); and positive history, clinical examination, and cough urethral pressure profile for GSUI (group 3). When compared with a group of 30 normal women (control group) the values for the urethral functional length (FL) and the maximum urethral closure pressure (MCUP) decreased progressively from group 1 to group 3. The pressure transmission ratio (PTR) was signficantly lower only in group 3.Tonometric values calculated for a group of 25 patients with GSUI recurring afterprevious surgical correction (group 4) were found to be comparable with group 3. These patients with recurrent GSUI had a FL decreased to 70% and a MCUP decreased to 48% of the normal values. The PTR was maintained at a normal value of 97% in patients with degree I recurrence, but was decreased to 68% in patients with degree II–III recurrence having the most severe impairment of the periurethral environment.
