PFE therapy instituted prior to radical prostatectomy aids in the earlier achievement of urinary incontinence. However, PFE has limited benefit in patients with severe urinary incontinence 16 weeks after surgery. There is a minimal long-term benefit of PFE training since continence rates at 1 year were similar in the 2 groups.
In 10 formalin-preserved adult male cadavers, dissection of the penile veins, arteries and nerves revealed information of clinical importance. The main venous drainage of the corpora cavernosa is via the cavernous veins, with additional drainage through the circumflex, deep dorsal, and crural veins. The arterial supply of the cavernous bodies varied remarkably, and the incidence of an accessory internal pudendal artery was high. The cavernous nerves, previously believed to be microscopic structures, were in fact identifiable grossly, and we were able to follow them from the region of the hilum of the penis to the prostate. The nature of these nerves was then confirmed by serial histologic sectioning. This detailed knowledge of the venous drainage and arterial and nervous supply of the penis, as well as of the relationships among the cavernous structures in the hilum of the penis, can elucidate the cause of erectile dysfunction and provide a valuable guide for surgical correction of vasculogenic and neurogenic impotence.
We report a series of 14 patients with 19 self-inflicted genital injuries during a period of 10 years. Of the patients 65% were psychotic and 35% were not psychotic. Repeated attempts at genital self-mutilation occurred in 31% of the cases, mainly in the psychotic group. A history of alcohol and/or drug abuse was present in 55% of the cases. Injuries varied from simple laceration of penile or scrotal skin to actual amputation of the penis or testis. The degree of injury did not differ between the psychotic and nonpsychotic patients. Surgical management and outcome varied according to the severity of the injury, the delay in presentation for treatment, and the degree of alteration in the mental status and behavior. Followup of 9 patients showed good cosmetic results with no immediate or delayed complications related to the injury. The functional results in patients with penile replantation were satisfactory. In 1 patient a urethral stricture developed that was successfully managed endoscopically. Erectile function was difficult to assess because of the marked diversity of sexual behavior in this group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
