Extravasation of urine was seen in 24 intravenous pyelograms taken for renal colic during the year 1973-74. A number of the patients presented with an acute abdomen. Extravasation took place of retained urine under pressure in the renal pelvis with leakage either around the clayces, from a fissure in the pelvis or even around the ureter. Extravasations of this type are in general rabsorbed without trace. In 5 cases, operation was necessary to drain a purulent collection which had developed in association with the extravasated urine.
1973年至1974年间，在24例因肾绞痛而进行的静脉肾盂造影中发现了尿液外渗。许多患者表现为急腹症。尿液外渗是由于肾盂内潴留的尿液在压力作用下，通过肾盂周围的裂隙、肾盂的裂缝甚至输尿管周围漏出。这种类型的外渗通常会不留痕迹地被吸收。在5例病例中，需要进行手术引流与外渗尿液相关的脓性积液。
