Magnetic resonance urography in the diagnosis of urinary tract obstruction after renal transplantation.
OBJECTIVE
To evaluate magnetic resonance urography (MRU) in the diagnosis of urinary tract obstruction after renal transplantation.


METHODS
A total of 31 patients with suspected urinary tract obstruction after renal transplantation were examined, and the results were compared with those from surgery and B-ultrasound examination.


RESULTS
The urinary tract after renal transplantation was clearly shown using MRU, and all patients were clearly diagnosed by MRU. Imaging results were consistent with those from surgery.


CONCLUSIONS
MRU is suitable for detecting urinary tract obstruction after renal transplantation. It is a alternative method for IVP and CT in patients with renal function impairment and uremia.
