MAGNETIC RESONANCE UROGRAPHY IN EVALUATING PATIENTS WITH CLINICALLY SUSPECTED OBSTRUCTIVE UROGRAPHY
Journal of Evidence Based Medicine and Healthcare
BACKGROUND Magnetic Resonance (MR) Urography comprises an evolving group of techniques with the potential for allowing excellent noninvasive evaluation of abnormalities of the urinary tract. MR urography is clinically useful to evaluate patients with clinically suspected urinary tract obstruction particularly beneficial in paediatric or pregnant patients or when ionizing radiation is to be avoided. The objectives of the study are-to find out the aetiological factors causing obstructive uropathy
... bstructive uropathy by MR urography and a detailed study of the aetiological factors in all cases. MATERIALS AND METHODS The study was carried out over a period of 18 months. A total of 35 patients were included in this study with ages between 14 and 70 years (average age 35 years). The patients were selected on the basis of sonological findings of hydronephrosis. The patients were then subjected to IVU followed by static and dynamic MRU. The results obtained were then compared followed by inferences. RESULTS MRU has superior sensitivity in the diagnosis of urinary tract obstruction. MRU is safer than IVU due to lack of iodinated contrast material and without using contrast material so having less contrast related events. It has a lower sensitivity in detection of urinary calculi as compared to other modalities. CONCLUSION MRU could be the imaging modality of choice in patients at risk of radiation like children, young adults and pregnant women.
