Compensatory renal enlargement was assessed in 19 adult patients who either had a nephrectomy (17 cases) or developed a functionless kidney following obstruction (two cases). Hypertrophy of the healthy kidney was assessed by comparing renal size on urography before and after removal or destruction of the diseased kidney. Compensatory renal enlargement was demonstrated in 40 per cent of the patients, including two patients in their sixties. The average increase in length was 3 per cent and the maximum increase in length was 9 per cent. Therefore compensatory enlargement does occur in adult life, but is much less than that occurring in childhood. The presence of a hypertrophied adult kidney over 17 cm in length usually indicates that the contralateral renal disease was present in childhood.
对19例成年患者的代偿性肾增大情况进行了评估，这些患者中，17例接受了肾切除术，2例因尿路梗阻后肾脏失去功能。通过比较患肾切除或破坏前后尿路造影的肾脏大小，来评估健侧肾脏的肥大情况。40%的患者出现了代偿性肾增大，其中包括两名60多岁的患者。长度平均增加3%，最大增加9%。因此，代偿性增大在成年期确实会发生，但远低于儿童期。长度超过17厘米的成年肥大肾脏通常表明对侧肾脏疾病在儿童期就已存在。
