Summary
Brief summary
The purpose of this investigation is to demonstrate the safety and efficacy of the GTU
artificial urinary sphincter device in restoring continence in males who have confirmed
urinary stress incontinence for a minimum of 12 months with primary etiology being radical
prostatectomy or transurethral resection of the prostate (TURP).
