Objectives:To determine the efficacy of gender, stone size, stone localization and degree of hydronephrosis in semirigid ureteroscopy success for ureteral stones.
Materials and Methods:We retrospecti-vely evaluated 244 patients with ureteral sto-nes trated with semirigid ureteroscopy betwe-en February 2003 and August 2011. Patient was seperated two groups that the stone size was larger and less than 15 mm. Stone localizati-on was classified lower, middle and upper ure-ter. Hydronephrosis degree was classified none, mild, modarete, severe and serious. Stone size, localization and hydronephrosis degree were evaluated from ultrasonography and compute-rized tomography.
Results: The mean age of the patients was 38.3 years (19-70). Of the 244 patients 98 (%40.1) were female and 146 (%59.9) were male. Of the stones 108 (%44.3) were right side,124 (%50.8) left side and 12 (%4.9) bilate-ral. Of the stones 144 (%59) were localized lo-wer ureter, 30 (%12.3) middle ureter and 70 (%28.7) upper ureter. Of the patients 36 (%14.8) had no hydronephrosis; 66 (%31.7) patiens had mild, 104 (%50) modarete, 32 (%15.4) severe and 6 (%2.9) serious hydronephrosis. The mean stone diameter was 12.4 (5-28) mm. Stone free rate was % 84.1. There was no efficacy of gender on the success rate (p=0.9). The success rate of lower, middle and upper ureter stones were % 93.8, % 83.3 and % 64.3 (p=0.04). According to hydronephrosis degree, the success rates were none % 91.7, mild % 89.4, modarete % 83.7, severe % 68.8 and seri-ous % 66.7 (p=0.027). Stones less than 15 mm had significant suc-cess rate (% 89.2) than stones larger than 15 mm (%64.6) (p=0.035). Only a patient of 244 (%0.4) underwent open surgery because of ureteral perforation.
Conclusion: Favorable factors for success of semirigid urete-roscopy for ureteral stones are less than 15 mm, lower or middle ureteral stones and none or mild hydronephrosis. Contrarily gen-der is not effective on success of ureteroscopy.
