Single-stage resection with intraoperative filter placement for right renal carcinoma with vena cava extension.

A unique feature of renal cell carcinoma is the extension of tumor into the inferior vena cava (IVC). We present the case of a 67-year-old man with a right renal mass, renal vein and IVC tumor thrombus, and acute occlusion of the common iliac veins. He underwent right radical nephrectomy, caval thrombectomy, bilateral iliofemoral vein thrombectomies, and intraoperative placement of an infrahepatic IVC filter.

Contralateral ureteroscopy performed at percutaneous nephrolithotomy: a unique evaluation of stone-free rates.

Purpose: Immediate stone-free rates of ureteroscopy are rarely reported. To establish accurate stone-free rates after ureteroscopy we assessed the safety and success of ureteroscopy for patients undergoing the procedure at contralateral percutaneous nephrolithotomy.

Materials And Methods: From our prospectively collected, institutional review board approved, percutaneous nephrolithotomy database we identified patients who underwent contralateral ureteroscopy for urolithiasis at percutaneous nephrolithotomy from December 2001 to December 2008.
