Stamey bladder neck suspension is thought to be an excellent procedure for stress urinary incontinence in selected groups of patients. However we must not ignore the complications of this procedure. We report a case of a patient who developed a delayed reaction with bladder wall erosion to the Dacron buttress used in Stamey urethropexy 19 years before. She was presented with pelvic pain and persisting irritative bladder symptoms. The treatment of choice was cystoscopic removal of suture and buttress. Tissue intolerance is a common problem with the use of different kinds of biomaterials in incontinence surgery. Careful cystourethroscopy is essential for early diagnosis and treatment if pain, infections and severe irritative symptoms occur postoperatively.
