RENAL TRACT - Hydronephrosis and hyperplasia of the prostate

The prostate is markedly and diffusely enlarged by a benign hyperplasia; it shows a prominent middle lobe. A thin piece of perspex outlines the path of the urethra. The bladder is dilated and the wall shows gross trabeculation. The ureters and the pelvis of each kidney are marked dilated.
This 88 year old man had a history of chronic obstructive respiratory disease and not long before he died was demonstrated to have a raised urea and creatinine. Death was due to lobar pneumonia.
