A comparative study of pneumovesical Cohen versus laparoscopic dismembered Lich-Gregoir ureteral reimplantation for primary obstructive megaureter in children

This study compares two surgical approaches for correcting primary obstructive megaureter in pediatric patients: the pneumovesical Cohen technique versus laparoscopic dismembered Lich-Gregoir reimplantation. The research evaluates clinical outcomes, surgical efficacy, and complication rates to guide surgical decision-making in managing this congenital urinary tract obstruction.
