Herniation of the urinary bladder through a congenitally enlarged inguinal canal in a cat

Abstract

A two-year-old, castrated male Main Coon cat was referred because of chronic, recurrent pollakiuria, haematuria, and acute vomiting. On clinical examination, a smooth, soft-tissue mass, suspected to be the urinary bladder, was palpable outside of the abdominal wall in the inguinal area. On radiographs, the urinary bladder was found to be extra-abdominal, and herniated through an enlarged right inguinal canal at exploratory coeliotomy. The left inguinal canal was also enlarged. The urinary bladder was repositioned and fixed to the caudal abdominal wall by incisional cystopexy and both enlarged inguinal canals were partially closed with an interrupted suture pattern.

Inguinal rupture with herniation of the urinary bladder through the scrotal fascia in a Shetland pony foal

“…In horses, the most common organ involved in inguinal herniation is the small intestine (Schumacher 2006). To our knowledge, herniation of the urinary bladder has not been reported in horses, although it has been reported in cats (Zulauf et al. 2007), dogs (Bellenger 1996) and man (Curr et al.…”

“…Urinary catheterisation confirmed that the mass in the inguinal region was the bladder however other diagnostic techniques have proved useful in other species. Air contrast radiography has been used to confirm bladder involvement in an inguinal hernia in a cat (Zulauf et al. 2007) but we believe that even in a foal this technique would prove difficult.…”

Diagnosis and surgical repair of entero-cystocele in a cat

“…Blunt trauma has been reported to be the most common cause of traumatic herniation in dogs and cats (Kraus, 1990;Shaw et al, 2003). Perineal and inguinal herniation of the urinary bladder both occur in the cat (Risselada et al, 2003;Zulauf et al, 2007). Rupture of an umbilical hernia and subsequent bladder herniation have also been reported in humans (Pandey et al, 2008).…”
