Urethral fistula formation after urethroplasty for hypospadias is a frequent complication. Repeated failures can occur even after multiple attempts at repair. A surgical procedure is described for a problematic resistant urethrocutaneous fistula (UF) with the transverse turnover flap using the Buck’s fascia of the corpus cavernosum. A 23-year-old male was admitted to our hospital with rec...

We present the case of a penile fracture involving the proximal corpus cavernosum, presenting as a hematoma extending into the scrotum. The presentation, diagnosis, and surgical approach, which differ from the more typical penile shaft fracture, are delineated.

OBJECTIVE To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. MATERIALS AND METHODS The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospe...

We investigated the effect of hyperthyroidism on the responsiveness of the rabbit corpus cavernosum smooth muscle. In male albino rabbits, hyperthyroidism was established by oral feeding of L-thyroxine at increasing dosages (150-450 microg/kg) over an 8-week period. This treatment produced a stable hyperthyroid state as indicated by the increased serum T4 levels. The reactivity of corpus cavern...

Diabetic erectile dysfunction is associated with penile dorsal nerve bundle neuropathy in the corpus cavernosum and the mechanism is not well understood. We investigated the neuropathy changes in the corpus cavernosum of rats with streptozotocin-induced diabetes and the effects of Icariside II (ICA II) on improving neuropathy. Thirty-six 8-week-old Sprague-Dawley rats were randomly distributed ...

Recently, intracavernous injection of some vasoactive drugs has been performed for the diagnosis and treatment of impotence. Despite extensive studies the mechanism of erection is still obscure. Therefore, the author studied the effects of some vasoactive drugs on isolated rabbit corpus cavernosum penis. Norepinephrine, phenylephrine or clonidine caused contraction of isolated rabbit corpus cav...

An animal model was developed to elucidate the effect of chronic obstruction of the internal pudendal artery on the responsiveness of the corpus cavernosum. In male albino rabbits, the internal pudendal artery was chronically ligated unilaterally with a silk tie and the occlusion was maintained for 1 month. The control group was sham-operated. The reactivity of corpus cavernosum tissue from the...
