Reflux nephropathy

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Urine reflux is the most common cause of chronic pyelonephritis.

Reflux is caused by:

  • incompetent vesico-ureteric valves
  • abnormal renal papillae which result in intra-renal reflux

Superimposed infection probably has a role in the pathogenesis of reflux-associated renal disease.
