Orthotopic urinary diversion with preservation of erectile and ejaculatory function in men requiring radical cystectomy for nonurothelial malignancy: a new technique.

PURPOSE: Nerve sparing techniques to preserve sexual function in men undergoing cystoprostatectomy have been well documented. The patient who desires to remain fertile with ejaculatory function poses an additional challenge. We describe a new technique for radical cystectomy and orthotopic diversion with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles. MATERIALS AND METHODS: Four men with a median age of 26 years presented with bladder pathology necessitating cystectomy, including signet ring carcinoma of the bladder dome, leiomyosarcoma of the anterior bladder wall, leiomyosarcoma of the lateral bladder wall, and extensive polypoid cystitis glandularis of the trigone and posterior wall refractory to conservative and transurethral management. All patients wished to maintain fertility and ejaculatory function. We detail the surgical technique of extirpation of the bladder and anterior proximal prostate en bloc with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles as well as construction of an orthotopic reservoir. RESULTS: Followup ranges from 4 months to 5 years. All patients remain completely continent and void to completion without difficulty. Erectile function is normal in all cases. Of 3 patients who ejaculate antegrade 1 has fathered a child. The remaining patient ejaculates retrograde. There has been no tumor recurrence. CONCLUSIONS: The technique of cystectomy with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles is an excellent option in men with nonurothelial malignancy or another pathological condition that necessitates cystectomy, and in whom preservation of fertility and potency is desirable. All of our patients are fully potent and achieve ejaculation. Even the patient with retrograde ejaculation remains fertile. In terms of practicality semen retrieval from urine is much simpler than epididymal sperm aspiration and in vitro fertilization.
