ABSTRACT
The aim of this study was to test a surgical technique for the treatment of stress urinary incontinence associated with genital prolapse through a transvaginal suspension anchored to the pubic bone. Thirty-seven patients with severe genital prolapse and urodynamically proven stress incontinence were operated on with this procedure from February 1998 to May 2000. Preoperatively a detailed history, pelvic examination and urodynamic studies were carried out. The degree of prolapse was assessed pre- and postoperatively in the lithotomy position in accordance with the classification proposed by Baden and Walker [8]. Two titanium bone screws with no. 1 polypropylene sutures attached to them and a battery-operated screw inserter are used to fix the vaginal sutures to the pubic bone bilaterally. The procedure is performed transvaginally with no abdominal or suprapubic incisions. Objective outcomes were assessed by symptom assessment, clinical examination and a full urodynamic evaluation at 6 months postoperatively, and annually by clinical evaluation. Subjective outcomes were assessed by directly interviewing the patients about their postoperative urinary symptoms and asking them to classify their level of satisfaction. An objective cure rate (no objective loss of urine during coughing in the absence of a simultaneous detrusor contraction) at the 6-month postoperative urodynamic evaluation was observed in 23 of 37 patients (62%). Recurrent anterior vaginal wall prolapse (grade 2) had developed in 7 of 37 patients (27%). Subjectively, 73% of the patients expressed satisfaction with the procedure. Early results using two bone screws into the pubis to fix the periurethral and perivesical tissues and vagina to the posterior surface of the pubic bone were disappointing. Based on our results we have abandoned the use of this procedure to correct stress incontinence associated with severe genital prolapse.
