KIDNEYS - Bilateral polycystic disease

The kidneys are replaced by multiple cysts which on the left-hand side are large; the ureters are dilated and tortuous and the bladder, seen as the partly cystic mass in the centre is hypoplastic. The histology of the lesions is that of renal dysplasia with large cysts (Type II polycystic kidney of Osanthanondh and Potter).
