| Abstract | ||
| Background: MRU is an excellent technique for the evaluation of the entire urinary tract. The aim of the study is to assess the capability of delayed sequence of MRU to distinguish between transient ureteric spasm that caused by ureteric peristalsis and ureteric stricture. Patients and Methods: The study carried on patients who referred for MRU examination.30 patients 15 males and 15 females. Adding multiple delayed sequential T2 coronal as well as sagittal fat suppressed single shot fast spin echo images after 2 ,4 or more minutes for visualization of the entire ureter and distinguish between transient ureteric spasm and fixed pathological stricture. Result : As regard ureteric spasm that caused by normal peristaltic movements, 36,7% of the examined cases (11 patients) showed relived spasm in the subsequent images repeated after 2 minutes ,while 43.3% (13 cases) showed relived spasm in the images repeated after more than 2 minutes. As regard pathological spasm 20% of cases (6 patients) had fixed true strictures which not relieved in the subsequent delayed images. Conclusion: T2-weighted MRU with multiple delayed sequence images is sufficient to identify all segments of the non-dilated ureter. It offers information on ureteral peristalsis and is able to distinguish between transient ureteric spasm due to peristalsis rather than the fixed pathological stricture. By adding multiple T2 fat suppressed single shot fast spin echo sequences after 2 ,4 or more minutes so, all ureteric segments could be visualized and the entire ureteric course could be evaluated . | ||
