Lich-Gregoir anti-reflux procedure; indications and results with 283 vesicoureteral units

While reflux is not the cause of the ascension of microorganisms into the urinary bladder, it enables bacteria to reach the kidney and fosters pyelonephritis, persistent infections and nephropathy with all related consequences. The efficiency of the Lich-Gregoir antireflux procedure must be judged by its results. The criterion of success in operations upon 225 children (283 vesicoureteral units) is the procedure's positive effect on renal growth and physical development of the patients by controlling pyelonephritis and the elimination of recurrent supravesical infections in more than 98 per cent of children operated upon.
