EFFECTIVENESS AND SAFETY OF ENDOSCOPIC REMOVAL OF IM-PACTED URETERAL STONES IN CHILDREN
Keywords:
children, ureteral stones, contact ureterolithotripsyAbstract
The treatment results of 73 children aged 5 to 18 years were retrospectively evalu-ated. The average stone size was 10.0 ± 0.6 mm in length and 5.5 ± 0.7 mm in width. Complete stone removal was achieved in 71 patients (97.2%). The total number of intraoperative complications was 24 (33.8%). Conversion from endo-scopic intervention to open surgery was required in two cases (2.8%) (Grade III). Ureteral mucosal injury was observed in 6.8% of children (Grade I), and ureteral perforation in 1.4% of cases (Grade II a). Ureteral mucosal burns occurred in 4.1% of patients (Grade II a) during laser lithotripsy. Deformation of the tip of the metal guidewire occurred in 16.4% of cases (Grade I). Postoperative complications were observed in 23 patients (31.5%). Elevated body temperature was noted in 8.2% of cases (Grade I), and hematuria in 9.6% (Grade I). Urinoma (Grade III b) and stein-strasse (Grade II a) were each observed in one child (1.4%). Systemic inflammatory response syndrome was also reported in one case. Ureteroscopic contact lithotripsy for impacted ureteral stones in children is an effective and safe treatment method.
