Malignant urinary bladder tumors fill 8th position in male and 18th position in female patients within the structure of oncological diseases. Urinary bladder tumor is in the 4th position among oncourological diseases according to the absolute rate of growth (the first three positions are: prostate cancer, renal cancer and testicular cancer). The multiplicity of rudiments and frequent recuring is characteristic for the tumors of urinary bladder.

    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. Nonepithelial tumors consist less than 1%.

    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 3D NLS research with Metatron Hunter 4025 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.
