A 2-year-old girl with recurrent urinary tract infection having slight left pelvicaliceal dilatation on her renal ultrasound underwent a Tc-99m DTPA diuresis renography. During the excretion phase, a prominent and persisting left pelvicaliceal stasis was noticed even after the diuretic injection. However, it disappeared simultaneously with an uncontrolled micturition. This patient is presented to show the effect of filled bladder on the physiological drainage of urine. Since urine flow in the urinary system is more complicated than simple drainage, a thorough understanding of the physiological basis for diuresis renography and the pitfalls of the technique is required for its appropriate use in the management of patients suspected of urinary tract obstruction.
一名2岁复发性尿路感染女童，肾脏超声显示左肾盂肾盏轻度扩张，接受了锝-99m二巯基丁二酸（Tc-99m DTPA）利尿肾图检查。在排泄期，即使注射利尿剂后，仍可见明显且持续的左肾盂肾盏淤滞。然而，在一次不受控制的排尿时，淤滞同时消失。展示该病例是为了说明充盈膀胱对尿液生理引流的影响。由于泌尿系统中的尿流比单纯的引流更为复杂，为了在疑似尿路梗阻患者的管理中正确使用利尿肾图，需要深入了解其生理基础及该技术的陷阱。
