Cytological study of bilharzial and non bilharzial urinay bladder carcinoma

One hundred cases presenting to the Urology Department, Tanta University Hospital were examined for the presence of bladder carcinoma. Cytological smears were examined after staining with Papanicolaou stain, as well as hematoxylene and eosin. Cystoscopic biopsies were also taken for histological evaluation. The accuracy of urine cytology was found to be proportional to the degree of tumor anaplasia. In bilharzial bladder carcinoma, urine cytology was accurate in 76% of cases while its accuracy was 65% in non-bilharzial cases. In squamous cell carcinoma, urine cytology was accurate in 69.4%, while in transitional cell carcinoma its accuracy was 77.4%. In adenocarcinoma, two cases out of three were diagnosed cytologically
