The Effect of Preoperative and Intraoperative Clinical Findings on Success of Endoscopic Management of Ureteral Stone
Journal Title: Dicle Tıp Dergisi - Year 2016, Vol 43, Issue 2
Abstract
Objective: We investigated the relationship between clinical data of patients who underwent ureterorenoscopy (URS) due to ureteral stone and stone free rates retrospectively. Methods: Clinical data of 83 patients who underwent URS in our clinic were retrospectively analyzed. Preoperative and intraoperative clinical parameters were recorded. Success was defined as not to detect > 4mm stone fragments 2 weeks after the operation. Appropriate statistical analysis were done for evaluating relationship between stone free rate and clinical data. Results: Mean age was 50.48±14.41 and male to female ratio was 2. Overall stone free rate was 83.2%. Postoperative fever, ureteral perforation were detected in 7 and 2 patients, respectively. There were no differences between success and failure groups in terms of age, sex, operation side, stone number, diameter, size, surface area, mean Hounsfield unit, usage of balloon dilatation. However with respect to preoperative grade of hydronephrosis (low grade: 95.2% vs high grade: 69.4%, p=0.006), stone location (distal ureter: 92.9% vs proximal ureter: 72.5%, p=0.014) and operation time (success: 60.0 (45.0-60.0) min. vs failure: 85.0 (60.0-97.5) min. p=0.048) we found statistically significant differences between the study groups. In addition stone free rate was 91.7% with anti-retropulsion device Stone cone, whereas it was 81.4% without any ureteral occlusion (p=0.347). Conclusion: We assume that anti-retropulsion devices or flexible URS should be prefered especially in patients with hydronephrotic proximal ureteral stone for higher stone free rate with lower auxiliary procedure. Key words: Ureterorenoscopy, ureteral stone, endoscopic stone management success
