Evaluation of MR urography in the diagnosis of Urologic diseases / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the diagnostic efficacy of MR urography(MRU) in the diagnosis of urinary diseases. Methods MR urography was performed in 58 patients with urologic diseases,inclu- dingrenal tuberculosis(6),various congenital anomalies of urinary tract(27),renal pelvis carcinoma(2), ureteral carcinoma (10),ureteral polyp(2),ureteral calculi(8) and iatrogenic ureteral stricture(3). Results MR urography provided high-resolution images of the kidneys and urinary tract in all patients.The characteristics of renal tuberculosis,urinary tract dilation and the various anatomic anomalies were depicted well.MR urography was successful in localizing the level of obstruction in all of the 58 patients(100%),although MR urography alone could not reliably determine the cause of obstruction in some cases. Conclusions In diagnosing urinary diseases,MR urography has its advantages and limitations.It should be used appropriately in diagnosing urinary diseases.
