Sonography for postoperative staging after malignant renal tumours was evaluated in this study based on multiple examinations in 63 patients. Sonography permits a critical examination of the liver, the abdomen in general, the retroperitoneal space, including the renal fossa and solitary kidney. Local recurrences after hypernephroma operation were found in 5.3% and after nephrectomy for renal pelvic carcinoma in 68%. Retroperitoneal lymph node metastases appeared in 17% of the patients operated on renal pelvic carcinoma and in 7.6% after hypernephroma operation. These data indicate that special attention should be drawn to the renal fossa after tumour nephrectomy. The higher incidence of recurrences in the renal fossa, and metastatic lymph node involvement in patients following nephrectomy for renal pelvic carcinoma compared with the situation after hypernephroma operation might be explained by the difference of the lymph drainage between the renal pelvis and renal parenchyma which, in addition, includes a separate ontogenetic development. The majority of secondary lesions in hypernephroma patients occur as lung and bone metastases which have been discovered by conventional X-ray examination. These data are not statistically evaluated in the study.
本研究基于对63例患者的多次检查，评估了超声检查在恶性肾肿瘤术后分期中的应用。超声检查可对肝脏、整个腹部、腹膜后间隙（包括肾窝和孤立肾）进行全面检查。肾细胞癌手术后局部复发率为5.3%，肾盂癌肾切除术后局部复发率为68%。肾盂癌手术后17%的患者出现腹膜后淋巴结转移，肾细胞癌手术后出现腹膜后淋巴结转移的比例为7.6%。这些数据表明，肿瘤肾切除术后应特别关注肾窝。与肾细胞癌手术后相比，肾盂癌肾切除术后肾窝复发率较高，且患者出现转移性淋巴结受累，这可能是由于肾盂和肾实质之间淋巴引流的差异所致，此外，还包括独立的个体发育过程。肾细胞癌患者的大多数继发性病变表现为肺和骨转移，这些已通过传统X线检查发现。本研究未对这些数据进行统计学评估。
