INTRODUCTION: No report has been published regarding the recommended surgical treatment in patients presenting with symptomatic primary asymmetrical vesicoureteral reflux (VUR): high grade on one side and low grade on the contralateral side. The aim of this study was to evaluate the effectiveness and outcome of combined Lich-Gregoir extravesical reimplantation and subureteric Deflux® injection, of high grade and low grade VUR respectively. Non-inferiority to bilateral cross-trigonal reimplantation was investigated in terms of surgical complications, number of post-operative fUTIs and need for re-intervention.
PATIENTS AND METHODS: A monocentric retrospective study was undertaken of all consecutive children with primary asymmetrical VUR on MCUG treated over an 18-year period (2004-2022). Surgery was indicated following an episode of febrile urinary tract infection despite appropriate non-operative management. Demographic and clinical such as length of hospital stay for pain management, use of urinary Foley catheter and complications were analyzed.
RESULTS: A total of 80 children met the study criteria: 40 patients underwent bilateral cross-trigonal re-implantation (Group 1) and 40 patients the combined Lich-Gregoir extra vesical reimplantation and Deflux® sub ureteric injection (Group 2). Complication and success rates were comparable in the two groups. The median hospital stay was significantly shorter for Group 2, with 50 % of patients who were discharged on day 1. Moreover, the data showed a significant lesser need in number and length of bladder catheter and ureteral stents in Group 2.
DISCUSSION: The technique proposed overcome the inconveniences of the other procedures that are commonly used in bilateral RVU: difficulty in retrograde catheterization or ureteroscopy after bilateral cross-trigonal reimplantation, the risk of transient bladder dysfunction after bilateral extravesical reimplantation and the low rate of success for high grade reflux of the sub ureteric Deflux® injection. The main limitation of the study lies in its retrospective nature and in the relatively short median follow-up.
CONCLUSION: The combined Lich-Gregoir extra-vesical ureteral reimplantation and sub-ureteric Deflux® injection for the treatment of primary asymmetrical VUR is an effective alternative to the gold standard cross-trigonal ureteral reimplantation. Moreover, the position of the ureteric orifice is not modified in the eventuality of endourological procedures into adulthood.
