[Transabdominal and transurethral scanning in the diagnosis of the bladder cancer stage]. / Transabdominal'noe i transuretral'noe skanirovanie v diagnostike stadii raka mochevogo puzyria.

Diagnostic potential in staging cancer of the urinary bladder was evaluated in 54 relevant patients aged 37-74 for transabdominal versus transurethral ultrasound scanning. In transabdominal scanning stages T2 and T3 cannot be distinguished separately, stage T1 was recognized definitely in 66.6%, T2-T3 in 65.6%, T4 in 70% of cases. Transurethral scanning appeared valid in staging T1 in 91.6%, T2 in 88.8%, T3 in 92.8%, T4 in 90% of cases. Histological studies in 54 patients showed that transurethral scanning can provide accurate results in staging cancer of the urinary bladder in 90.7% of cases. The findings support clinical value of the method as highly informative in staging cancer of the bladder. Basing on both transabdominal and transurethral scanning, ultrasound picture for each stage of the cancer was characterized.
