Abstract
Caroli's disease is a rare congenital disorder with incidence rate of approximately 1 in 1 000 000 population. Renal anomalies which may be associated with Caroli's disease include medullary sponge kidney (MSK), cortical cysts, adult recessive polycystic kidney disease and rarely autosomal dominant polycystic kidney disease. Exact incidence of MSK in patients of Caroli's disease is not known. There are only a handful of reported cases of this association in literature. We hereby report a case of Caroli's disease with MSK with nephrocalcinosis. He presented to primary health centre with symptoms of urethral stricture due to lichen sclerosus et atrophicus and was managed with repeated co-axial dilatation but was never evaluated for underlying chronic renal insufficiency due to MSK. The thorough clinical examination and proper evaluation is important in patient of urethral stricture with underlying chronic renal insufficiency to avoid delayed diagnosis, management and related complications.
