The kidney has been bivalved to show a grossly dilated renal pelvis and calyceal system. While not visible in the picture, the ureter immediately distal to the PUJ measured 4mm in diameter.
This is an macroscopic example of chronic PUJ obstruction with marked hydronephrosis. Histological examination of the pelvo-ureteric junction showed mild submucosal fibrosis and mild hypertrophy of the muscle wall but there was no evidence of malignancy.
