Клинические особенности колоректального рака, осложненного инвазией в мочевую систему

In 9 cases it was detected the genuine invasion of the CRC into the bladder with the formation of colovesical fistula in 5 cases. In the clinical picture in similar observations it was recorded the body temperature rise to 39-40°C, dysuria, pneumaturia, and fecaluria. Conclusions. Invasion into the bladder is found in 2.8 % of cases of CRC. Combination of fever and dysuria in patients with colorectal cancer, especially if these symptoms have stages, provide a reliable criterion for tumor invasion into the bladder. Only computed tomography of the abdominal cavity, retroperitoneal space and pelvis with intravenous contrast enables to establish the presence of colovesical fistula and its topographic and anatomical features.
