Partial Penile Amputation and Preputial Urethrostomy in a One-year-old German Shepherd Following a Traumatic Laceration: A Case Report

Background: Penile trauma in dogs can lead to life-threatening hemorrhage. Severe lacerations may need partial penile amputation combined with urethrostomy to maintain urinary function and prevent further complications. Methods: A one-year-old intact male German Shepherd dog was referred to Small Animal Hospital of University of Tehran after jumping over a metal fence, that had deeply lacerated the penis. A tourniquet had been applied at a previous facility to control hemorrhage but evident active hemorrhage was still present. Premedication included cefazolin, tramadol, meloxicam, pantoprazole, tranexamic acid, and vitamin K. Under general anesthesia induced with propofol and maintained with isoflurane, urethra was catheterized and the os penis was shortened with a rongeur, bleeding vessels were ligated with ۳-۰ PGA, and the urethral mucosa was sutured to the tunica albuginea incorporating some cavernous tissue in each bite with ۴-۰ PDS. The prepuce was then shortened and closed with ۳-۰ nylon. Results: Postoperative treatment included antibiotics (ceftriaxone and ampicillin), analgesics (tramadol, and gabapentin), and meloxicam as a non-steroidal anti-inflammatory drug. The dog was discharged with an Elizabethan collar for ۱۴ days and was also scheduled for suture removal after two weeks. The urinary catheter was kept for a week and the owner was instructed to keep the peri-catheter area clean and lubricated to prevent complications. At the three-month follow-up, the dog exhibited complete healing, normal urination with no hematuria and pain, and without any complications. Conclusion: This case shows how penile amputation together with preputial urethrostomy can be an effective, life-saving surgical procedure for severe penile trauma in dogs, when it is done correctly. Timely intervention and proper surgical technique are crucial for restoring function and preventing complications.
