Laparoscopic vesico-ureteral reimplantation with Lich–Gregoir approach in children: medium term results of 159 renal units in 117 children



Vesico-ureteral reflux (VUR) represents one of the most significant risk factors for acute pyelonephritis in children. Surgery is an important part of its management. Laparoscopic ureteric reimplantation using the Lich–Gregoir technique is an option for VUR. The aim of this study is to assess short- and medium-term outcomes of this approach.

Materials and methods

This is a retrospective study including all children with VUR treated by laparoscopic extravesical ureteral reimplantation with the Lich–Gregoir technique in University Hospital of Saint-Etienne from August 2007 to May 2016. Surgery was performed after the age of 12 months in cases with repeated urinary tract infection (UTI) and a deterioration of renal function. All patients were followed-up post operatively.


117 children (92 girls, 25 boys) representing 159 renal units were included. The mean age at surgery was 47.1 months (±32.7 months). The mean follow-up was 59.3 months (±31 months). The resolution rate for VUR in terms of no febrile urinary UTIs was 98.3%. The mean operative time was 96 min (±37.7 min) for unilateral procedures and 128 min (±46.1 min) for bilateral procedures. The mean hospital stay was 25.3 h (±6.3 h). There was no difference between males and females regarding age, weight, renal function or follow-up duration.


Laparoscopic reimplantation with Lich–Gregoir technique is an efficient, quick and safe technique for the management of VUR. The success rate is comparable to open techniques with the advantages of laparoscopic approach; this can potentially be performed as a Day Case procedure.
