[FlowSecure artificial urinary sphincter for the treatment of stress urinary incontinence after radical prostatectomy].
OBJECTIVE
To diffuse the concept and implantation surgical technique of a new prosthesis for the treatment of stress urinary incontinence, the Flow Secure artificial urinary sphincter.


METHODS
The prosthesis is a single silicone piece filled with saline solution which has the following parts: (1) Pressure regulation reservoir, (2) assistance reservoir for stress situations, (3) control pump with self-sealant port and (4) a cuff. One of the main characteristics is the self-sealant port enables pressure adjustment depending of the clinical needs of the patient as many times as necessary.


RESULTS
The surgical technique is simple and the level of continence achieved excellent. The only complication inherent to the Flow Secure design is perforation of the cuff during the act of pressurization, but it has been corrected by designing a new control pump which can not be punctured. Self limited scrotal edema/hematoma are frequent; they can be avoided minimizing the time of trocar use. The remainder complications are common with the AMS 800 and other implantable prosthesis.


CONCLUSIONS
Despite midterm good results, we need to wait for a greater number of patients with the Flow Secure sphincter and longer follow up to determine the definitive role of this prosthesis for the treatment of urinary incontinence.
