AIM: Intravenous Urography (IVU) as a diagnostic modality has limitations in @entity1 of @entity3551 with @entity8 . Our aim was to study the technique and diagnostic accuracy of Magnetic Resonance Urography (MRU) @entity3551 and to correlate the findings with IVU. METHODOLOGY: Forty-eight @entity1 , selected over a six-month period, based on mild to severe pelvicalyceal @entity384 on screening ultrasonography, underwent an IVU; those having non-obstructive @entity384 were excluded (18 @entity1 ). Thirty @entity1 (age range 10 to 75 years) with @entity384 underwent MRU. These were obtained using an open MRI unit (Siemens Magnetom Open Viva) with low-dose @entity7241 (0.01 mmol/kg body weight) using various MRI sequences. MRU studies were classified as 'excellent' or 'diagnostic' and data generated was compared with that of IVU. RESULTS: MRU studies were 'excellent' in twelve and 'diagnostic' in eighteen @entity1 . Of the sixty @entity262 ( @entity262 ) evaluated in thirty @entity1 , there were thirty-seven calculi, nine pelvi-ureteric junction (PUJ) obstructions, six with @entity8 , four @entity8 and one each of @entity8 , pelvic mass ( @entity46 ), duplex moieties, ureterocele and vesico-ureteric reflux. MRU better depicted moderate-severe @entity384 , staghorn and urethral calculi, @entity8 , extrinsic ureteric and PUJ obstruction. IVU better depicted small calculi and mild @entity384 . CONCLUSIONS: In these thirty @entity1 of @entity3551 , low magnetic field, open MRI units and low-dose @entity7241 provided cost-effective MRU studies with excellent diagnostic utility. MRU scored over IVU in @entity1 with moderate-severe @entity384 , staghorn and urethral calculi, @entity8 , extrinsic ureteric and PUJ obstruction.
