Preputial urolith deposition and urate urolith obstruction in a calf

OpenAlex English

Abstract This case report aimed to describe a rare case of urate urolith deposition and preputial obstruction in a 6‐month‐old calf. The owner reported that the calf was purchased from an auction 1 month ago and the calf was having difficulty urinating. The calf was depressed, and crusty painful masses were found in the prepuce. Blood urea nitrogen and serum creatinine concentrations were within reference ranges. Radiographic imaging revealed urolith deposition in the prepuce, and the preputial orifice was obstructed with a urolith. Cystocentesis was carried out and uroliths were removed using local infiltration and regional anaesthesia. The analysis of the mineral composition indicated that the uroliths' composition was uric acid. Forceps were used to carefully manipulate the urolith to remove it from the obstructed preputial orifice. The animal had a perfect recovery 1 week later.
