Carcinoma bladder: comparative evaluation of urinary cytology, excretory urography and ultrasonography

A total of 63 patients with 85 bladder tumors were evaluated with excretory urography (IVU), ultrasonography and urine cytology, before being subjected to cystosocopy and biopsy. An attempt was made to evaluate accuracy of detection by different modalities, individually and combined together. Untrasonography and IVU detected 90 percent and 75 percent of tumors respectively while cytology was positive in 63 percent patients. Ultrasonography was superior to IVU, and, Urinary cytology, despite its low catch, could detect few cases where both the previous mentioned modalities had failed. Larger tumors situated on posterior and lateral walls were consistently detected by ultrasonography. Tumor staging by ultrasonography correlated well with final staging in infiltrating tumors. Thus it is concluded that the two non-invasive procedures, sonography and urine cytology must be routinely used for evaluation of fresh cases and in follow up of bladder tumors.
