Severe hydronephrosis and hydroureter associated with ectopic ureters were diagnosed in 2 dogs. Surgical transplantation of the ectopic ureters into the urinary bladder resulted in urinary continence in both dogs. Intravenous urography revealed a marked decrease in the size of hydronephrosis and hydroureter in both dogs 28 to 35 weeks after surgery. In 1 dog with bilateral ureteral ectopia, kidney size and renal function remained normal for 5 years after surgery. A dog with one ectopic ureter and an associated ureterocele had a marked reduction in size of the affected kidney and an apparent decrease in function of that kidney, as indicated by decreased opacification on an intravenous urogram.

A 2-month-old, female cat was presented for abdomen dilation. The patient was undernourished, and severe left hydronephrosis was diagnosed after clinical, ultrasonographical and radiographical examination. Although pyelography was performed in order to visualise the ureteral course, surgery was necessary to reach a final aetiological diagnosis and treatment. At gross examination, the left ureter crossed the renal capsula at the level of the caudal renal pole, and the subcapsular ureteral segment was markedly dilated. Distal to the renal capsula, the left ureter was very thin when compared to the right. The parenchyma of the left kidney, as suggested by ultrasonographical evaluation, was extremely reduced in thickness. An ureteronephrectomy was performed. Histopathological evaluation revealed glomerular sclerosis and diffuse parenchymal fibrosis. Severe hydronephrosis derived from an altered renal pelvic anatomy and abnormal ureteral course determining functional stenosis. Diagnosis of congenital anomaly before development of complications such as hydronephrosis could have allowed a surgical renal capsulectomy and obstruction relief. To the author's knowledge, this is the first report of severe hydronephrosis associated to altered renal pelvic anatomy and proximal ureteral ectopia in cat.
