Magnetic resonance urography in the diagnosis of urinary tract obstruction after renal transplantation.

ABSTRACT

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.
