The significance of dilatation of the collecting system of the transplanted kidney and its relationship to bladder distention was reviewed in 39 renal recipients examined by sonography (94 studies). The degree of pelvicaliceal (PCS), ureteral, and bladder distention was graded and correlated with the 24-h urine output, nuclear renal scan, and clinical follow-up. marked PCS distention can indicate obstruction (33%), especially when there is no associated bladder distention (60%) and a fluid collection lies along the path of the ureter. The 24-hr urine output did not influence the degree of PCS distention.
对39例接受肾脏移植的患者进行超声检查（共94项研究），以评估移植肾集合系统扩张的意义及其与膀胱扩张的关系。对肾盂肾盏（PCS）、输尿管和膀胱的扩张程度进行分级，并与24小时尿量、核素肾扫描及临床随访结果进行相关性分析。明显的PCS扩张可能提示梗阻（33%），尤其是在无相关膀胱扩张（60%）且输尿管走行区有液体积聚时。24小时尿量不影响PCS扩张程度。
