摘要

Introduction. Neurogenic erectile dysfunction resulting from cavernous nerve (CN) injury is a major complication caused by radical prostatectomy. The use of platelet-rich plasma (PRP) on the nerve-injured site has shown promising results for the nerve regeneration. However, the effects of PRP injection in corpus cavernosum after bilateral CN injury have never been investigated. Aim. To assess the neuroprotective effect of PRP injection in corpus cavernosum after bilateral CN injury. Methods. Male Sprague-Dawley rats were randomly divided into three groups: Group I underwent sham operation, while the remaining two groups underwent bilateral CN crush. Crush injury groups were treated at the time of injury with an application of PRP or normal saline only injection in the corpus cavernosum, respectively. Four weeks later, erectile function (EF) was assessed by CN electrosimulation, and CNs as well as penile tissue were collected for histology. Main Outcome Measures. Intracavernous pressure (ICP) monitored during electrical stimulation of CNs; myelinated axons number of CNs and dorsal penile nerve; collagen type change, number of apoptotic cells, and mRNA expression of caspase-3 and transforming growth factor-β1 (TGF-β1) in the corpus cavernosum. Results. Four weeks after surgery, in the vehicle-only group, the functional evaluation showed a lower mean maximal ICP than that in the sham group (P
