BACKGROUND: Ureteral lesions can be difficult to diagnose. The value of ureteral biopsy in addition to ureteral washings has not been defined clearly.
METHODS: All ureteral washings and biopsies with follow-up that were performed at a single institution were reviewed.
RESULTS: In total, 39 patients underwent ureteral washing, ureteral biopsy, or both and had follow-up: Eighteen patients had urothelial tumors at follow-up (14 high-grade carcinomas, 3 low-grade carcinomas, and 1 papillary urothelial neoplasm of low malignant potential). The sensitivity was 79% for washings and 71% for biopsies (P = 1.0), for a combined sensitivity of 100%. Biopsies often were scant, and cell blocks from biopsies and washings often were of value.
CONCLUSIONS: Ureteral washings and biopsies had similar sensitivity and appeared to be complementary. Cell blocks often are useful for both specimen types.
