title: Scintigraphic evidence of abnormal ureteric peristalsis following urological surgery.
abstract: OBJECTIVE
  To investigate the effect of urological surgery on ureteric peristaltic activity.
  
  
  METHODS
  Ureteric peristalsis was assessed in a sample urological population (n = 29 patients) and the findings compared with a control population (n = 14 patients).
  
  
  RESULTS
  The incidence of disordered peristalsis was significantly increased (P < 0.05) following urological surgery and, in particular, the incidence of retrograde peristalsis was very significantly increased (P < 0.01) following ureteric division and re-anastomosis.
  
  
  CONCLUSIONS
  The results of this study are consistent with a central role for myogenic activity in the conduction of ureteric peristalsis in man.
