TUL is most useful and effective for removing the stones of inferior ureter. In other hand aminophylline can decrease urinary tract spasm. Then, combination of TUL and aminophylline help us to reduce the complication of TUL. Methods and materials: We have study on 87 case of renal colic who referred to Imam Khomeini hospital of sari and Tooba clinic. This study was a double blind systematic randomized clinical trial that patients were divided to two group as 1 and 2: group one includes patients who received aminophylline and group 2 were selected as our control samples. Our sample size was calculated by statistic analysis according to recent studies. Result: The average of TUL time was 5.12± 1.77 min in group 1 and 6.59± 3.47 min in group 2(p0.05). ESWL was used in one patient of group 1 because of remaining of stone, but 7 patients of group 2 did not response to Transureter lithotripsy, then they needed ESWL. Complication were not seen in patient who received Aminophylline and mean arterial pressure and heart rate was equal in two group. Conclusion: The difference of TUL Time between two groups was meaningful. As you know, aminophylline has an antispasmotic effect on urinary tract and tract with smooth muscle, and according to our finding, usage of aminophylline can reduce the complication of TUL and increase success rate of Lithotripsy in this patient. In other hand, it complications was few. LA eng UL http://armaghanj.yums.ac.ir/article-1-43-en.html M3 ER -
