Abstract

Complete or partial urethral obstruction results in progressive nephropathy in the subsequent calyxal and renal parenchymal damage. We report a case controlled giant hydronephrosis mimicking multiple polycystic kidney disease (PCKD). The fluid content in the collecting duct is about 1.4 liters. A 40 years old man with renal dimensions measuring RK: 118 x 62 mm; LK: 120 x 65 mm respectively reported for ultrasound examination. There was no evidence of malignancy after 8-month follow-up ultrasonography with drug treatment in the Internal Medical Unit; plus urologic evaluation and documentation. Expelled urinary volume via catheter was consistently measured. Although clinical symptoms and alternate list of diagnosis were suspected, it turned out to be a case of large hydronephrosis. Accurate diagnosis became challenging due to distortion of renal parenchyma and calyxal atrophy. Examining clinical presentations, real-time sonogram evaluation and treatment medication, it is concluded that ureteric calculus may be a main cause of bilateral hydronephrosis.
