In all the countries in majority of cases (90-95%) the tumors of urinary bladder are morphologically transient cell carcinomas; the rest of cases relate to squamous cell cancer and adenocarcinoma. Non-epithelial tumors consist less than 1%.

The main and the most reliable method of urinary bladder cancer diagnostics in clinical practice is still cystoscopic examination with gathering of cytological or histological material. But this method does not allow estimation of tumor invasion depth into bladder wall. The depth of invasion is one of the essential factors when choosing surgical treatment: transurethral resection is not possible in case of affection of wall’s muscular layer.

Computer tomography, magnetic resonance tomography and transurethral ultrasonic examination are mainly used over the last years as corrective diagnostics methods to determine the depth of urinary bladder tumor invasion. According to the information provided by Nesterova V. and others the recent method of Bioplasm software may become crucial both when specifying the prevalence rate of bladder cancer and when performing case monitoring. Such advantages of the method as availability, painlessness and absence of radiation exposure allow performing multiple researches when carrying out case monitoring.
