In 41 cases of roentgenologic filling defects in renal pelvis and ureter, which could not be determined exactly preoperatively, we could confirm the diagnostic value of cytology from washings of renal pelvis and ureter (lavage cytology), especially in preoperative diagnosis of carcinoma of renal pelvis and ureter. Ten of fourteen tumors (71%) were detected by this method. The diagnostic reliability increased with tumor-stage and was more accurate than the normal exfoliative urinary cytology. In five cases of hypernephromas invading the renal pelvis lavage cytology was not successful and we had obtained only false negative results. In roentgenologic filling defects that were not tumor-induced especially uric acid stones, inflammatory processes, blood clots and renal cysts, we had no false positive results. Our findings are discussed together with the literature.
在41例术前无法准确判定的肾盂和输尿管X线充盈缺损病例中，我们证实了肾盂和输尿管冲洗液细胞学检查（灌洗细胞学）的诊断价值，尤其在肾盂和输尿管癌的术前诊断中。14例肿瘤中有10例（71%）通过该方法检测到。诊断可靠性随肿瘤分期增加而提高，且比正常尿脱落细胞学检查更准确。在5例侵犯肾盂的肾细胞癌病例中，灌洗细胞学检查未成功，仅获得假阴性结果。在非肿瘤性的X线充盈缺损中，尤其是尿酸结石、炎症过程、血凝块和肾囊肿，我们未得到假阳性结果。我们结合文献对研究结果进行了讨论。
