Abstract

Objectives: To report the signalment, indications for surgery, postoperative complications and medium-/long-term outcomes in dogs undergoing partial penile amputation.

Materials and methods: Retrospective case series. The electronic medical records of a single small animal referral hospital were searched between January 2014 and January 2021 for dogs that underwent a partial penile amputation. Data collected included signalment, presenting clinical signs, indication for partial penile amputation, surgical technique, postoperative complications and outcome.

Results: Ten dogs were included in the study. Indications for surgery were treatment of preputial neoplasia (n=5), penile neoplasia (n=1), idiopathic paraphimosis (n=3) and chronic urethritis (n=1). Five of five preputial tumours were cutaneous mast cell tumours, and the penile tumour was a squamous cell carcinoma. All dogs recovered uneventfully from surgery with a median postoperative hospitalisation time of 28.8 hours. Two of the three dogs treated for paraphimosis had major postoperative complications requiring further resection of the tip of the penis at 2 weeks and 24 months. Four dogs had minor complications managed without surgical intervention. The outcome was good to excellent in nine of nine dogs for which medium- or long-term follow-up data were available.

Clinical significance: In this group of dogs, partial penile amputation, performed with or without concurrent resection of the prepuce, was a well-tolerated surgical procedure with low intraoperative and postoperative complication rates and good functional outcomes. Partial penile amputation should be considered for conditions affecting the distal penis and prepuce.
