Sensitivity of urine cytology in detecting high-grade urothelial carcinoma in patients with neoplastic urinary bladder diverticula: A major cancer center experience.

The characteristics and sensitivity of urine cytology in bladder diverticula were investigated in association with neoplasia, with an emphasis on primary intradiverticular bladder cancer. The results indicated that urine cytology remains a reliable screening and diagnostic test for detecting IDBC, with sensitivity similar to that for detecting EDBC, and no significant difference was noted between voided and cystoscopic samples.
