Growth of the kidney following unilateral antireflux surgery

Measurements of the mean renal lengths pre-operatively, 3 months, 1, 3 and 5 years post-operatively in patients with unilateral reflux showed that renal growth accelerates unilateral antireflux surgery. The growth spurt was confined to the first post-operative year and was maximal in the first 3 months following operation and was identical in both kidneys. The cause of these alterations in renal growth are obscure but freedom from infection, increased dietary intake and improved concentrating ability of the kidney are significant factors.
