Hydrodilation of the ureteral orifice in children renders ureteroscopic access possible without any further active dilation.

摘要

PURPOSE: We review our experience with hydrodilation of the ureteral orifice for ureteroscopic access in children. MATERIALS AND METHODS: We retrospectively reviewed the results of 30 ureteroscopic procedures performed in 26 children who were followed for 6 months. Ureteral access was obtained with the assistance of a hand irrigation pump without any further active dilation in all cases. RESULTS: A total of 26 patients (86.7%) were completely stone-free after 1 procedure. There was no major complication such as ureteral perforation or avulsion. Mild flank pain was observed in 8 cases (26.7%). Predominant symptoms of bladder spasm were observed in 6 cases (20%). At 6-month followup no patient had pyelonephritis or demonstrated hydronephrosis related to ureteral stricture. CONCLUSIONS: Our study shows that hydrodilation of the ureteral orifice in children renders ureteroscopic access possible with no additional active dilation and no associated complications.
