10547              HYDRONEPHROSIS ASSOCIATED WITH ABERRANT RENAL ARTERY

A man of 72 died of hypertension and renal failure. His left kidney had been removed 38 years previously allegedly for perinephric abscess. He was found to be hypertensive 10 years before death and a right hydronephrosis and a urethral stricture was present. On his final admission the BP was 215/125 and the BUN 50 mg% rising to 115 mg%. Terminally he became anuric.

The specimen consists of a greatly enlarged kidney 16 cms in length. There is very marked intrarenal and extrarenal hydronephrosis and hydrocalycosis, but a good deal of renal tissue remains. A large aberrant renal artery enters the lower pole and the ureter is kinked over this artery.
