Medical management of ureteral stricture-induced hydronephrosis in a cat.

A 3-year-old neutered male domestic shorthair cat was evaluated for hematuria. Ultrasonography and CT scanning identified moderate right-side hydronephrosis associated with right proximal and distal ureteral strictures, as well as partial stenosis of the left distal ureter. Medical management, including fluid therapy, ureteral muscle relaxants, and corticosteroids, was initiated but failed to improve progressive renal pelvic dilation as assessed on serial ultrasound scans. This case highlights the limited efficacy of conservative therapy and contributes to the growing body of evidence on the management of feline ureteral strictures.
