We managed expectantly 23 patients with renal pelvic dilatation and unilaterally obstructive diuresis renograms. Serial renograms showed changes in ipsilateral relative renal function in 8 kidneys (4 deteriorated). Pressure-flow studies demonstrated low pressures on perfusion of 8 kidneys. Eight patients eventually required pyeloplasty, mostly for loin pain. Therefore, serially obstructive diuresis renograms can be associated with preserved renal function, with high pelviocaliceal compliance being a possible explanation.
我们对23例肾盂扩张和单侧梗阻性利尿肾图的患者进行了观察。系列肾图显示8个肾脏的同侧相对肾功能有变化（4个恶化）。压力-流量研究表明8个肾脏灌注时压力较低。8例患者最终需要肾盂成形术，主要是因为腰痛。因此，系列梗阻性利尿肾图可能与肾功能保留有关，肾盂肾盏顺应性高可能是一个解释。
