[A diagnostic algorithm based on transrectal echography in failure of surgery correcting stress urinary incontinence].

Transrectal ultrasound is a dynamic imaging diagnostic technique for the study of stress urinary incontinence (SUI). The highest efficiency is obtained in the study of failed corrective surgery of SUI. Our group studied 23 patients reporting clinical SUI after undergoing corrective surgery, 23.3% patients with transrectal ultrasound showed no condition that could justify it (bladder neck hypermobility, intrinsic sphincteral incompetence, calcification of suspension threads, urethra diverticulum...); 34.8% showed bladder neck hypermobility, indicative of failed corrective surgery; 34.8% showed presence of open urethra at rest, an echographic sign of intrinsic sphincteral incompetence; and in 4.3% cases the existence of intravesical calcifications of the suspension threads was diagnosed. Transrectal ultrasound can become the choice test to perform in this group of patients, leading to the performance of other diagnostic tests and offering an adequate customized solution for each patient's problem.
