Acute complete ureteral occlusion may cause little change in the collecting system, especially if there is an intrarenal collecting system. Chronic obstruction can produce an enlarged, normal, or atrophic kidney, again depending on the length and degree of obstruction, as well as the presence of an intrarenal or extrarenal collecting system. Detailed history was taken and a thorough clinical examination was done for all the patients with Hydronephrosis due to Ureteric Calculi. All relevant and routine investigations were done in these cases to establish diagnosis. Ethical clearance has been obtained from the institution for the same. All these patients were examined, evaluated & data was collected according to the proforma. Amongst the study subjects, mild grade of hydronephrosis was seen in 42 cases (56%), thus being the most common grade of hydronephrosis. About 28 cases (37%) showed moderate grade of hydronephrosis and severe grade of hydronephrosis was seen in 5 cases (7%).
