Role of percutaneous pelvic node aspiration cytology in the management of bladder carcinoma.

: Six of the 23 patients with bladder carcinoma who underwent percutaneous pelvic node aspiration biopsy cytology for staging purposes showed positive findings from nodal chains. Pelvic lymphadenectomy revealed no false-positive or false-negative cytologic results. The fine needle aspiration of opacified pelvic nodes under fluoroscopic control is of great diagnostic value, with a high accuracy in detecting nodal extension of bladder carcinoma and providing a rational basis for proper therapy. Positive aspiration results may be accepted as a basis for therapeutic decisions. Since the metastatic involvement of multiple nodes makes any therapeutic treatment as well as cystectomy completely useless, positive aspirations from more than two nodes may spare patients an unnecessary radical surgery.
