Ureteral obstruction or perforation must be considered as a cause of poorly functioning renal transplants. Sonography and radionuclide scanning will demonstrate outflow obstruction and/or pararenal fluid collection, but do not usually provide sufficient information on the site of the lesion. In these cases we have successfully used fine-needle puncture of the renal pelvis under sonographic guidance, and antegrade pyelography. This technique shows excellent anatomical details of the renal pelvis and ureter.
输尿管梗阻或穿孔必须被视为肾移植功能不佳的一个原因。超声检查和放射性核素扫描将显示流出道梗阻和/或肾周液体积聚，但通常无法提供关于病变部位的足够信息。在这些情况下，我们成功地在超声引导下对肾盂进行了细针穿刺，并进行了顺行肾盂造影。该技术能很好地显示肾盂和输尿管的解剖细节。
