Giant Pyonephrosis Due to Ureteropelvic Junction Obstruction: A Case Report

Pyonephrosis is a suppurative infection of upper urinary tract due to obstruction of the ureter. It is usually associated with suppurative damage of renal parenchyma and renal function loss. Patients are mostly symptomatic but may remain asymptomatic in 15% of cases. Severe infection in pyonephrosis may lead to urosepsis and may endangered life, if timely not treated with surgical intervention. We hereby report a rare case of Giant Pyonephrosis (GP), contained 11 liters of pus, due to Ureteropelvic Junction (UPJ) obstruction presented with haematuria. The patient was treated with open nephrectomy. The aetiology, clinical features, diagnosis and management of pyonephrosis with the review of literature of GP in the background of a rare case report have been discussed here.
