Aneurysmal Dilatation of Corpus Cavernosum as an Unusual Complication of Dorsal Penile Neurectomy / 대한남성과학회지

ABSTRACT

A 43-year-old man presented painless protruding mass on left side of penile shaft only during erection. 1 year ago he had a dorsal penile neurectomy for the treatment of premature ejaculation at local clinic. A protruding cavernousal aneurysm about 2 cm in diameter was developed 6 months after surgery and confirmed on penile duplex ultrasonography after PDE5 inhibitor ingestion with visual sexual stimulation. We have observed the lesion every month and found there was slight enlargement for the last 3 months without any other symptoms. We performed cavernosoplasty under the genereal anesthesia. There was a round cavernosal aneurysm on the left side of penile mid-shaft about 4cm in diameter after artificial erection with intracavernosal saline injection. We prevented cavernosal protrusion by covering the aneurismal surface with bovine pericardium patch (Supple Peri-Guard(R)). There was no side effect for 6 months postoperatively. This is an unusual type of complication of dorsal penile neurectomy.
