[Tips and tricks for nerve-sparing cystectomy].

The aim of radical cystectomy with subsequent urinary diversion is to combine a safe oncological outcome with a satisfactory lower urinary tract function. Recent findings on the anatomy, physiology and nerve supply of the pelvis have resulted in a modified nerve-sparing cystectomy technique. A number of studies have shown that the oncological outcome is not compromised by such a technique; in particular the rate of local recurrences is not enhanced. Nerve-sparing cystectomy is of importance for the lower urinary tract function, including continence status after orthotopic bladder substitution and erectile function. Prerequisites for a nerve-sparing technique are a profound knowledge on the nerve supply of the pelvic organs and a subtle surgical technique. Recent surgical developments, for example in prostate and seminal vesicle sparing cystectomy techniques, indicate that it will be feasible to restore lower urinary tract and also sexual function after radical cystectomy and orthotopic bladder substitution.
