Study design, materials and methods
The bulbar urethra is accessed by a perineal incision, completely mobilised and surrounded. Here the curved cuff is placed and closed to the appropriate size. The equilibration of pressures is watched and adapted. Then a canal is digitally carved beyond the left spermatic cord returning to the middle of the scrotum. The pump-/tank system is placed in this subdartos pouch and the wound is closed.
Interpretation of results
The "single-incision"-implantation-technique for the Zephyr ZSI 375 artificial urinary sphincter is a quick and safe procedure and does not produce additional side affects as known from the recent techniques.
