Giant Hydronephrosis Due to Ureteropelvic Junction Obstruction in A 53-Year-Old Male: A Case Report

The hydronephrotic kidney, resulting from an uretero-pelvic junction obstruction (UPJO), presents commonly as a clinical condition, with the presence of usually no more than 1‑2 liters in the collecting system, but a very small number of cases of giant hydronephrosis (GHs) has been reported in adults. In this case report a 53-year-old male was admitted to the Vamshodaya Hospital Kolar, Karnataka, India in November 2023 with an abdominal pain since 15 days and abdominal distention since 6-months. Computed tomography was performed, finding large thin walled cystic mass in right side of abdominopelvic region (40x32x27cm) showing few incomplete septations, fluid density within lesion and causing significant mass effect and displacing the rest of the abdominal contents. Such cases are rarely presented; therefore the aim of the present case study was to document a clear case of GH resulting from UPJO.
