Polypoid cystitis, pyelonephritis, and obstructive uropathy in a cow.

Polypoid cystitis, pyelonephritis, and obstructive uropathy was found in a cow with hematuria, dysuria, and colic. The cow was treated with penicillin, multiple B vitamin supplementation, and isotonic sodium chloride. Polypoid cystitis, diagnosed in this cow by use of endoscopic examination, is a common response to chronic inflammation of the bladder and can lead to obstructive uropathy. Although endoscopic confirmation of this diagnosis may not always be feasible, recognition of corresponding clinical signs can allow timely, appropriate treatment.
