A retrospective analysis was performed on 34 female patients who underwent corrective surgery for stress urinary incontinence over a 4-year period at the Toa Payoh Hospital. These patients were offered surgery only after an adequate trial of medical therapy, pelvic floor exercises and weight reduction. Bladder neck suspension operations were performed via the Burch, Stamey and modified Pereyra techniques. Towards the later part of this study, endoscopic injection of Collagen was performed as a salvage procedure in 2 patients. The Burch colposuspension gave uniformly good results, with all patients being completely dry. Seventy percent and sixty percent complete continence were achieved via the modified Pereyra and Stamey techniques respectively. Three patients required additional surgical procedures. Using these techniques, the overall results showed that 27 patients (79.4%) had complete urinary continence following surgery, while the remaining 7 patients (20.6%) experienced significant improvement of symptoms.
