Renal cell carcinoma with tumor thrombus in the lower cava vein reaching the right atrium - Case report and brief review of the literature.

Approximately 15% of cases of renal cell carcinoma (RCC) can invade the inferior vena cava, leading to the formation of a thrombus inside it, which can reach the cardiac chambers in up to 1% of cases. This article reports a case of RCC with venous thrombus that reached the right atrium. The patient underwent radical nephrectomy with lymphadenectomy and tumor thrombectomy with extracorporeal circulation associated with hypothermia, without total cardiac arrest.

Bladder function evaluation before renal transplantation in nonurologic disease: is it necessary?

Objective: To determine whether preoperative cystometry and a pressure flow study (PFS) are necessary in patients with end-stage renal disease from nonurologic causes who will undergo renal transplantation.

Methods: From April 2009 to June 2010, 30 patients scheduled to undergo renal transplantation were prospectively evaluated with cystometry and PFS. The evaluation was performed immediately before and 6 months after renal transplantation.
