Erection failure as a sequela to obstructive urolithiasis in a male goat.
A 14-month-old 40-kg Anglo-Nubian buck was referred for erection failure after recurrent bouts of obstructive urolithiasis. Previous episodes of obstructive urolithiasis were treated successfully with amputation of the urethral process, followed by an exploratory celiotomy and insertion of an indwelling Foley catheter into the bladder. The buck had been capable of intromission prior to the most recent episode of urethral obstruction. The results of physical examination and electroejaculation did not reveal any abnormalities, except failure to achieve erection. Contrast radiography of the corpus cavernosum penis (CCP), however, revealed failure of contrast media to migrate proximal to the sigmoid flexure. A diagnosis of obstruction of the CCP caused by cavernositis and fibrosis secondary to urolithiasis was made. A poor prognosis was given for breeding soundness. Although breeding soundness following obstructive urolithiasis may be enhanced by surgical intervention, impotence may result from obstruction of blood flow through the CCP secondary to urethral rupture or urethritis.
