Ultrasound findings for the right kidney on the first day of referral of a dog with perineal hernia, bladder retroflexion, and a mass lesion in the hernial sac. Mild renal pelvis distension (5.9 mm) can be observed.

Ultrasonography showed bladder displacement into the hernial sac, with slight dilatation of the renal pelvis in the right kidney (Fig. 1).
Ultrasound findings for the right kidney at 2 days after repair surgery in a dog that presented with perineal hernia, bladder retroflexion, and a mass lesion in the hernial sac. Severe distention of the right kidney can be seen. The short and long axes of the renal pelvis measure 31.1 (A) and 37.3 (B) mm, respectively. The right ureter also showed severe distention (13.7 mm).

Abdominal ultrasonography revealed severe distention of the right renal pelvis (31.1 x 37.3 mm) and ureter (13.7 mm) (Fig. 2).
Gross appearance of the urinary bladder during exploratory laparotomy after perineal hernia repair in a dog. The bladder neck is strangulated by fibrous tissue connected to the necrotic adipose tissue, causing discoloration and congestion of the urinary bladder (asterisk). The fibrotic band is isolated by the tip of the forceps. A mildly dilated left ureter can be identified (white arrow).

Careful inspection of the bladder neck revealed that a fibrous band connected to the mass-like degenerated adipose tissue had caused the strangulation (Fig. 3).
Gross appearance of the urinary bladder after resolution of the strangulation that developed after perineal hernia repair in a dog. The strangulation was resolved by fibrous tissue removal. The color of the bladder has recovered to normal immediately after the procedure. Dilation of the right (black arrow) and left (white arrow) ureters has persisted.

The fibrous tissue was dissected and removed, after which the color of the bladder serosa returned to normal (Fig. 4).
