Anuria due to inadvertent prostatectomy during cryptorchidectomy

Cryptorchidism is the most common inherited congenital disorder of sexual development in canines, with a prevalence ranging from 8.2% to 13% (1–3). Due to the high occurrence rate and the risks involved with retained testicles, cryptorchidectomies are widely performed. By 5 days of age, the testes should be completely descended in the dog (4). However, 1 study showed that approximately 25% of testes in dogs not descended by 10 d would descend later (by 14 wk) but none after 6 mo (4,5–8). If undescended after puberty, the testis becomes hypoplastic, degenerate, and fibrotic. Castration is very important in these patients due to the increased risk of sertoli cell tumors, seminomas, interstitial cell tumors, and spermatic cord torsion (1). In the current report, castration of the retained testicles, or cryptorchidectomy, was performed on an 8-month-old Labrador retriever dog. Although an experienced veterinarian performed the procedure, improper visualization of the gross anatomical structures led to inadvertent prostatectomy, and subsequently euthanasia.
