Abstract

A study was made of the possibilities to diagnose and classify urothelial tumors of the upper urinary tract by means of exfoliative cytology on voided urine using a membrane filter method. In a series of 30 patients with renal pelvic tumors and 13 patients with ureteral tumors an overall agreement between cytology and histopathology was obtained in 25 cases (58%). None of the Grade 1 tumors or of the non invasive Grade 2 tumors were regarded as positive by cytology whilst 2 out of 5 invasive Grade 2 tumors had positive cytologic reports. The series included 24 patients with poorly differentiated or anaplastic tumors, 17 of whom had positive cytology (71%). By excluding from the series 13 patients with obstructed urinary passages or radiologically nonfunctioning kidneys on the tumor side an agreement between cytology and pathology was reached in 83% of the cases, regardless of tumor grade, and in 17 out of 18 patients with Grade 3-4 tumors (94%).
