ABSTRACT

Introduction: renal cell carcinoma is the tenth leading cause of cancer. The therapeutic approach is primarily surgical with curative intent. Transcatheter embolization is a mode of Interventionist Radiology which consists of obliterating the arterial flow for therapeutic purposes. This technique is used as preoperative treatment in renal tumors.
Objetive: analyze the causality of embolization of renal tumors performed at Hospital General de México.
Material and Method: A retrospective, observational, analytical study of patients who underwent renal embolization from August 2013 through November 2016.
Results: 31 renal embolizations were performed. 68% were indicated as palliative treatment and 32% as a preoperative procedure. Gelfoam paste was used in 94% and microparticles in 6%. Pre- and post-procedure figures for serum creatinine and hemoglobin were, on average, 1.26 and 1.21 mg/dL and 12.2 and 12.6 mg/dL, respectively.
Conclusion: in our institution embolization of renal tumors was used primarily as a palliative method. Larger quantities of embolizing agent were used as the tumor stage advanced. Patients who underwent palliative embolization presented reduction or stability of serum concentrations of creatinine and hemoglobin. Embolization is a current alternative in treatment of advanced renal carcinoma; however, we still lack sufficient data to compare optimum parameters among sub-groups of patients with and without preoperative embolization. Nevertheless, we conclude that renal embolization remains an effective, safe, and minimally invasive interventionist procedure.
