The patients with end-stage renal disease on periodic hemodialysis often develop acquired cystic renal disease, and they have renal tumours more commonly than the normal population.
To evaluate the usefulness of echography for the evaluation of these lesions and the prevalence of acquired cystic renal disease and occult renal tumours in patients treated with hemodialysis during years, a prospective ultrasonographic study was carried out. To this end, renal echographic studies were performed in 43 asymptomatic patients treated with periodic hemodialysis during 5 years or more. Patients with renal polycystic disease were excluded from the study.
The overall prevalence of acquired cystic renal disease was 86%. It was higher in males (96%) than in females (70%). Two patients (4.6%) had malignant renal tumours.
In view of the high prevalence of tumours in acquired cystic renal disease, it is suggested that periodic echographic studies should be carried out in patients with end-stage renal disease treated with hemodialysis during years to detect renal carcinoma in subclinical stage.
接受定期血液透析的终末期肾病患者常发生获得性肾囊肿病，且他们患肾肿瘤的几率高于正常人群。
为评估超声检查对这些病变的评估价值以及接受血液透析多年的患者中获得性肾囊肿病和隐匿性肾肿瘤的患病率，开展了一项前瞻性超声研究。为此，对43例接受定期血液透析5年及以上的无症状患者进行了肾脏超声检查。患有肾多囊病的患者被排除在研究之外。
获得性肾囊肿病的总体患病率为86%。男性（96%）高于女性（70%）。两名患者（4.6%）患有恶性肾肿瘤。
鉴于获得性肾囊肿病中肿瘤的高患病率，建议对接受多年血液透析治疗的终末期肾病患者进行定期超声检查，以发现亚临床期肾癌。
