Shyam Joshi Sir thank you very much.
This is a case of congenital megacalycosis. It is mostly asymptomatic and discovered by accidentally or as a result of its complications like hematuria, infection and stone formation. Number of calyces is increased as compare to normal. Puigbert described first of this condition. No treatment is required for asymptomatic case. Annual follow up with USG is required.
One basic question sir ,how to read renogram systemically.
