Objective: To report implantation of the new FlowSecure™ artificial urinary sphincter with conditional occlusion in a female bladder neck, describe surgical technique and suggest minor modifications to accommodate the device for universal female implantation. Patient and Methods: A spina bifida female patient with urodynamically proven stress incontinence due to sphincteric incompetence associated to atonic detrusor was implanted with the new artificial sphincter. Operating time was one and a half hours. The cuff was adjusted to the bladder neck with no problems. Excess belt removed from the cuff was preserved and used for loose fixation of tubing and reservoirs in the right paravesical space. The control pump was placed in the right labia. The prosthesis was implanted at atmospheric pressure zero. Results: The device was easily implanted. There were no perioperative complications. Catheter was removed 24 h post-implantation and patient achieved immediate total continence. There was no need for device pressurization at subsequent follow-up. The patient needed intermittent self-catheterization for emptying her bladder because of impaired detrusor contractility. Conclusions: Despite that the new FlowSecure artificial urinary sphincter has only been used for bulbar urethral implantation, we have successfully implanted the device in a female bladder neck with excellent clinical results. Cuff lengthening and connecting tubes shortening would probably enable all female patients to be suitable for implantation. To the best of our knowledge, this is the first time the device has been implanted in a bladder neck.
