  • Abstract
  • Look Inside

In a consecutive series of 105 retrograde pyelographies performed in 88 kidneys over a period of 8 years, the overall incidence of pyelorenal backflow was 16. 2%. The occurrence of pyelorenal backflow was significantly higher in retrograde pyelograms with hydronephrotic change (11/43) than without hydronephrotic change (6/62). Pyelorenal backflow was found more frequently in retrograde pyelograms showing ureteral stenosis (4/15) or ureteral stone (3/12) than showing no abnormal finding (0/25).We conclude that the appearance of pyelorenal backflow on retrograde pyelograms may indicate the presence of acute ureteral obstruction.
