<b><i>Hypothesis:</i></b> A structurally sound puboprostatic ligament (PPL), like the pubourethral ligament in the female, is the core structure for control of stress urinary incontinence (SUI) in males. <b><i>Methods:</i></b> The hypothesis was tested at several levels. Twelve transperineal ultrasound examinations were performed to confirm reflex directional closure vectors around the PPL, with digital support for the PPL rectally and cadaveric testing with a tissue fixation system (TFS) minisling, and finally, 22 cases of postprostatectomy incontinence were addressed only with retropubic insertion of a 7-mm TFS sling between the bladder neck and perineal membrane to reinforce the PPL. <b><i>Results:</i></b> On ultrasound testing, 3 urethral closure muscles were confirmed to act reflexively around the PPL to close the urethra distally and at the bladder neck. A finger was inserted rectally, pressed against the symphysis only on one side of the urethra at the origin of the PPL that controlled urine loss on coughing. The mean pre-op pad loss was 3.8 pads at 9 months; the mean post-op loss was 0.7 pads; 13/22 (59%) patients were 100% improved; 7/22 (31%) improved >50% but <100%; 2/22 (9.1%) improved <50%. <b><i>Conclusions:</i></b> The 7-mm-wide TFS minisling is the first retropubic minisling for postprostatectomy urinary incontinence. It differs significantly from transobturator male operations surgically and in modus operandi. As in the female, reconstruction of the PPL alone was sufficient to cure/improve SUI, suggesting that preservation of the PPL is of critical importance during retropubic radical prostatectomy.

Anatomie der weiblichen HarnröhreDie Harnröhre der erwachsenen Frau hat eine Länge von 2,5-4 cm und kann an jeder Stelle stenosieren. Die Sphinkter-Aktivität wirkt auf der gesamten Länge, die Harnröhre besitzt 2 glatte Muskelschichten, eine äußere zirkuläre und eine innere longitudinale Schicht. Dieser glatte Muskel dünnt sich nach distal aus, speziell die äußere
