[Retroperitoneoscopy in diagnosis of lymphogenic metastases of bladder cancer]

Application of retroperitoneoscopy improved diagnosis of regional metastases urinary bladder cancer because it provided relevant morphological verification. Fifty patients were examined for urinary bladder cancer. Factors influencing the frequency of lymphogenic dissemination were studied. A comparative evaluation of the results of direct contrast lymphography and of retroperitoneoscopy suggests that a complex of procedures including retroperitoneoscopy should be used for diagnosis of regional metastases of urinary bladder cancer (T3-4).
