Antireflux procedure by Lich-Gregoir. Indications and results.

Reflux is not the cause of the ascension of microorganisms into the urinary bladder, yet it enables bacteria to reach the kidney and fosters pyelonephritis, persistent infections and nephropathy with all its consequences. The efficiency of the Lich-Gregoir antireflux procedure has to be judged by its results. The criterium of operative success in 190 renal units (146 children) is the positive influence on renal growth and physical development by controlling pyelonephritis and eliminating recurrent supravesical infections in more than 98% of the operated children.
