During a 14-month period 73 satisfactory fluoroscopic studies were done on 59 kidney transplant recipients. Ureteral peristalsis was seen in 90 per cent of these studies and there was no difference between patients receiving living related donor kidneys and those receiving cadaveric kidneys. When ureteral activity was studied during rejection episodes only 54 per cent of the studies showed activity. An effort was made to relate aperistaltic ureteral activity to renal function, warm ischemia time, urinary tract infection, number of rejection episodes and tissue matching but no positive correlation could be made except the concurrent clinical diagnosis of rejection.
