- Abstract:
- Objective To assess the efficacy of high-pressure balloon dilation of ureterovesical junction for primary obstructive megaureter in children.Methods A total of 19 children with primary obstructive megaureter underwent high-pressure balloon dilation under general anesthesia from January 2015 to December 2020.Results Significant postoperative improvement of hydroureteronephrosis were noted in 12 cases after single treatment, 5 children achieved cure after a second treatment and another 2 underwent ureteral bladder reimplantation after a failure of dilation.Insertion of guide wire failed in one case while another child showed no improvement after a second dilation.At 6 months post-operation, radionuclide imaging indicated improvements of renal function and hydroureteronephrosis in 17 children after dilation.During an average follow-up period of 14(7-26) months, there was no sign of recurrence.Conclusion High-pressure balloon dilation of ureterovesical junction is both safe and effective for primary obstructive megaureter in children.
