title: Hydronephrosis and pyelonephritis associated with an anomalous vas deferens in a bull.
abstract: Hydronephrosis and pyelonephritis were diagnosed in a 2-year-old Limousin bull. Salient historical and clinical observations included weight loss, anorexia, intermittent colic, polyuria, polydypsia, and an ammoniacal breath odor. Intravenous treatment with fluids and antibiotics did not induce a favorable response. An anomalous vas deferens was observed on postmortem examination. The vas deferens ended in a blind polyp that protruded into the lumen of the urethra. This polyp may have caused chronic intermittent obstruction, predisposing to the hydronephrosis and pyelonephritis.
