Popis: Background Semi-rigid uretroscopy (URS) is a common intervention approach for lower ureteric stones. Ureteral dilatation is frequently needed before URS to enable ureter accessing. Aminophylline is known by its muscle relaxant effect and has been suggested to be effective in ureteral dilation. Objectives To evaluate the effect of intravesical administration of aminophylline on ureteroscopy and to measure intraureteral pressure Methods This prospective randomized controlled study included 50 before and after aminophylline injection. patients with lower ureteral calculi. In group A, the ureter was dilated by intravesical aminophylline whereas in group B balloon dilator was used. Intraureteral pressure was measured using pressure transducer connected to invasive pressure monitor. Results No statistically significant difference was noticed between both groups in operative time, intra operative complication, need for ureteral stenting or stone free rate. However, post-operative pain and haematuria were statistically significantly higher among balloon group compared to aminophylline group. In group A, there was statistically significant decrease in intraureteral pressure after injection of aminophylline (7.80 ± 1.71) compared to before injection (12.2 ± 1.85) with p-value < 0.001. Conclusion Aminophylline is effective in ureteral dilatation when intravesically injected with less frequent post-operative pain and hematuria.
