title: [Lavage-cytology of the renal pelvis and ureter with special reference to tumors (author's transl)].
abstract: On 138 patients with radiologic filling defects in the ureter and renal pelvis lavage cytology was done. With this method it was possible to recognize clearly 39 of 47 urothelial tumors of renal pelvis and ureter (81,3%). Lavage cytology failed in patients with hypernephroma. Severe cellular atypias could be seen in patients with urolithiasis and inflammation. The diagnostic reliability of lavage cytology with urothelial tumors of renal pelvis and ureter is far greater than that of exfoliative urinary cytology and reaches results as good as those from brush biopsy.
