[Prosthetic repair of genito-urinary prolapses by the transobturateur infracoccygeal hammock technique: medium-term results].

OBJECTIVES: The aim of this study was to evaluate the anatomical and functional medium-term efficacy and possible complications of vaginal prosthetic surgery with transobturator and infracoccygeal support to treat genital urinary prolapse.

MATERIAL AND METHOD: A prospective and monocentre study was conducted, from February 2002 till February 2005. All the patients with or without stress urinary incontinence (SUI), who presented either a recurrent prolapse, either a voluminous genital prolapse of stage 3 or 4 notably a dominant cystocele, either a post-hysterectomy vaginal vault prolapse or even a prolapse of lesser importance but in a context of obesity, were operated according to the transobturator infracoccygeal sling technique.

RESULTS: One hundred and three patients with a mean age of 65+/-11 years (41-84) were enrolled, with once on two SUI. Thirty percent of the patients had recurrent prolapse and 44% post-hysterectomy vaginal vault prolapse. With a mean follow-up of 32+/-13 months (12-53), the success rate of the technique was estimated to be 97% anatomically (three failures) and 89% in terms of urinary symptoms (69% of patients were cured, 20% were improved and 11% failed). Quality of life of the patients was sharply improved and their degree of satisfaction was high. Sexuality of the population which was limited here (44% of active patients) did not seem very modified by surgery. Complications were represented by a case of urinary retention observed with a secondarily pelvic haematoma, a low rectal injury without consequence, three blood transfusions. Three patients developed de novo overactive bladder. The prostheses exposure rate was 16%, once requiring on two one re-intervention. Prostheses were perceived during the postoperative evaluation by the examiner for 43% of the patients. But examination was painful only in 9,7% of the cases.

CONCLUSION: Combined treatment of vaginal prolapse and associated urinary incontinence is possible by the use of a single transvaginal prosthesis. The medium-term anatomical and functional results are very good. The results on continence are good and a subsequent specific procedure is always possible in the case of failure or insufficient improvement. The prostheses exposure rate is similar to that observed with synthetic transvaginal prostheses. The exact tolerance of vaginal prosthetic repair of the prolapse of young women being this day an unknown, we remain careful on the extension of the indications of this technique in this category of population.
