RODRIGUEZ FABA, Óscar et al. The treatment of urinary incontinence by injectables: Analysis of our series. Arch. Esp. Urol. [online]. 2005, vol.58, n.3, pp.227-231. ISSN 0004-0614.

OBJECTIVES: To determine the efficacy of endoscopical injections for the treatment of stress urinary incontinence (SUI), evaluating its low invasiveness and positive impact on quality of life. METHODS/RESULTS: Between 1997-2003 30 procedures of periurethral injection of various substances for urinary incontinence were performed at our department in women between 47-80 years. All patients were evaluated before surgery, clinically and urodynamically, in accordance to international standardized parameters (filling pressure/flow studies, maximum urethral closure pressure, LPP-leak point pressure). The kind of material employed for injection, surgical technique and satisfaction degree were also evaluated. RESULTS: The indication for surgery was SUI in 17 cases (56.6%), and mixed urinary incontinence in 13 cases (43.3%). 16 cases (53.3%) had history of previous surgery for SUI. Regarding urodynamic parameters,19 patients (63.3%) have a maximum urethral closure pressure below 25 H2O cm, and 22 patients (73.3%) had a leak point pressure below 60 H2O cm. Collagen was employed in six cases (20%) and macroplastic in 24 (80%) (14 of them with the MIS system). 22 patients had three injection sites (73.3%). Mean follow-up was 38 months. Continence outcomes were evaluated in relation to complete continence (12 cases, 40%), mild incontinence and patient satisfaction (11 cases, 36.6%), and severe incontinence (7 cases, 23.3%). CONCLUSIONS: 1-To achieve acceptable results it is mandatory to do the best possible indication (Mc Guire type III SUI). 2.-There is an excellent relationship between minimal invasiveness and good results.
