In addition to surgical procedures of the urethra, cystotomy and tube cystostomy are effective methods for treatment of obstructive urolithiasis in ruminants. These two procedures preserve the animal's ability to breed and allow for removal of cystic calculi. Regardless of the surgical procedure performed, urethral obstruction may recur after surgery. Once a diagnosis of urolithiasis is made, other intact or castrated males in the herd or flock are assumed to be at risk for this disease, owing to the central roles of diet and environment in its pathogenesis. Mineral analysis of calculi and evaluation of the ration are necessary to determine potential causative dietary factors. Dietary modification, salt supplementation, and improved water management are important preventive measures.
