Retrograde perfusion sphincterometry with a flexible cystoscope: method of troubleshooting the AMS 800.

We developed the technique of retrograde perfusion sphincterometry to troubleshoot the AMS 800 device. We implanted artificial urinary sphincters in men who were incontinent after prostatectomy and performed intraoperative retrograde perfusion sphincterometry. Retrograde perfusion sphincterometry using a flexible cystoscope is simple and allows early recognition of intraoperative urethral injury and mechanical malfunction.
