Abstract | BACKGROUND: METHODS: We conducted a retrospective analysis of the records of 105 women who underwent collagen injection for urinary stress incontinence between March 1991 and April 1995. Preoperative assessment included uroflowmetry, residual urine determination, and urodynamic studies. RESULTS: Of the 105 women in our series, 95 patients (90.5%) had initial successful results at 3 months (61.0% cured, 29.5% significantly improved) while 4 patients (3.8%) had slight improvement and 6 (5.7%) failed surgical correction. One year after the procedure, the success rate dropped to 81.9% (86 patients) with 46.7% cured and 35.2% significantly improved. Nine patients (8.6%) had slight improvement and 10 patients (9.5%) failed surgical correction. Eight patients (7.6%) with initial unsatisfactory results underwent additional sessions of collagen injection and were subsequently either cured or had significant improvement. Twenty-three patients (21.9%) suffered a relapse. The mean time to relapse was 13.3 months, and 6 of those who relapsed underwent repeated injections with favorable results. Complications were minimal; 6 patients had temporary retention of urine, and 2 patients had urinary tract infections. CONCLUSIONS:
