The findings of regular ultrasound examination of 439 renal transplants in 419 patients performed during a 16-year period were reviewed to determine the significance of collecting system dilatation. Dilatation was observed in 80 cases. 34 of these proving to be obstructed. Pelvic dilatation was an insignificant finding except when appearing within a month of transplantation. One third of cases developing pelvic dilatation within a month showed progressive dilatation with obstruction subsequently confirmed. The majority of cases developing unheralded dilatation of pelvis and calyces were obstructed and all such patients require further investigation. Recurrence of dilatation following relief of obstruction was associated with recurrent obstruction in eight of nine cases. Consideration of ultrasound appearances allows more critical selection of patients for further investigation when dilatation is seen.
回顾了在16年期间对419例患者的439例肾移植进行定期超声检查的结果，以确定集合系统扩张的意义。在80例中观察到扩张。其中34例被证实存在梗阻。盆腔扩张是一个无意义的发现，除非在移植后一个月内出现。在一个月内出现盆腔扩张的病例中，三分之一显示进行性扩张，随后证实存在梗阻。大多数出现肾盂肾盏意外扩张的病例存在梗阻，所有此类患者都需要进一步检查。梗阻解除后扩张复发与9例中的8例复发性梗阻相关。当看到扩张时，考虑超声表现可以更严格地选择患者进行进一步检查。
