BACKGROUND: Primary vesicoureteral reflux (VUR) is a congenital urinary system condition that can lead to renal impairment. While the laparoscopic Lich-Gregoir anti-reflux surgery is an established treatment, previous research has primarily focused on reflux recurrence and urinary tract infection (UTI) rates. The postoperative recovery of the frequently associated ureteral dilation remains an under-investigated area, which is crucial for understanding ureteral functional restoration.
OBJECTIVE: To investigate the resolution timeline of ureteral dilation following laparoscopic Lich-Gregoir anti-reflux surgery in children and to identify factors influencing this recovery.
STUDY DESIGN: A retrospective analysis was conducted on 92 children (139 ureters) with primary VUR and ureteral dilation who underwent the laparoscopic Lich-Gregoir procedure. The primary outcome was the time from surgery to the resolution of ureteral dilation, defined as a diameter of <7 mm on ultrasonography.
RESULTS: Postoperative ureteral diameter and renal pelvis dilation significantly decreased. Overall, 90% of ureteral dilations resolved within 6 months post-surgery. Grade IV-V VUR, a history of preoperative UTI, and bilateral surgery were identified as independent risk factors for significantly delayed resolution.
DISCUSSION: The identified risk factors reflect more severe initial anatomical impairment and greater surgical complexity. Establishing this resolution timeline provides a data-driven reference for clinicians to effectively manage postoperative expectations.
CONCLUSION: Laparoscopic Lich-Gregoir anti-reflux surgery is effective in resolving VUR-caused ureteral dilation 6 months postoperatively. Grade IV-V VUR, bilateral surgery, and a history of preoperative UTI are risk factors for delayed resolution.
