Surgical management of penile anomalies in mongrel dogs

Abstract

Penectomy combined with pre-scrotal urethrostomy was performed to establish a permanent urethral opening cranial to the scrotum following penile removal for the management of urethral affections and penile anomalies in castrated dogs. Four mongrel dogs were presented with a history of penile trauma of various etiologies. Based on clinical and physical examination findings, penectomy with pre-scrotal urethrostomy was performed in all cases. The procedure resulted in a tension-free anastomosis of the urethra to the skin at the pre-scrotal region, with no major postoperative complications observed. The study primarily focused on early complications, including mild intermittent haemorrhage from the stoma during urination, and late postoperative complications, particularly urethral stricture formation. The findings suggest that pre-scrotal urethrostomy combined with penile amputation is an effective surgical technique for the management of penile anomalies and may help reduce the risk of urethral stoma stricture formation in dogs.
