Circumferential Inferior Vena Cavectomy Without Caval Replacement in the Management of Renal Cell Carcinoma with Tumor Thrombus.

Purpose Of Review: Renal cell carcinoma presents a unique proclivity for vascular involvement giving rise to a peculiar form of locally advanced disease so-called tumor thrombus. To date, the only curative strategy for these cases remains surgery, which should aim to remove every vestige of macroscopic disease. Most of the preexisting literature advocates opening the vena cava to allow tumor thrombus removal and subsequent venous suture closure.

Development of an immune-nutritional prognostic index in patients with muscle-infiltrating bladder cancer candidates for radical cystectomy.

Introduction: Muscle-infiltrating bladder tumor (MIBT) has a recurrence-free survival (RFS) of 50% at 5 years. Although neoadjuvant chemotherapy (NCT) has increased it by 8%, which group of patients benefits the most from this treatment remains unclear.

Objective: Evaluate the prognostic value of immune-nutritional status in patients with MIBT who are candidates for cystectomy, and to develop a score that allows identifying patients with a worse prognosis (pT3-4 and/or pN0-1).

Deceased donor kidney procurement: Systematic review of the surgical technique.

Introduction: Kidney procurement procedure must be carried out following a standardized technique in order to optimize kidney grafts for their subsequent implantation.

Objectives: Review of the available literature on kidney procurement procedure.

Material And Methods: Narrative review of the available evidence on deceased donor kidney procurement technique after a search of relevant manuscripts indexed in PubMed, EMBASE and Scielo written in English and Spanish.

Peritoneal carcinomatosis after partial nephrectomy for renal cell carcinoma: Our experience and literature review.

Objective: Peritoneal carcinomatosis associated with renal cell carcinoma is an infrequent entity, usually associated with large renal masses, and with a very rare presentation after surgery of localized renal tumors. Our objective is to review the literature and analyze the factors involved in the development of peritoneal carcinomatosis after laparoscopic partial nephrectomy in localized tumors.

Material And Methods: We present our experience with two cases of peritoneal carcinomatosis after laparoscopic partial nephrectomy.

En Bloc Resection of Right Renal Cell Carcinoma and Inferior Vena Cava Tumor Thrombus Without Caval Reconstruction: Is It Safe to Divide the Left Renal Vein?

Introduction: It has been suggested that inferior vena cava (IVC) reconstruction following resection of retroperitoneal tumors with IVC tumor thrombus (TT) is not required when adequate collateral circulation is present. There are no reports evaluating mid-term effects on renal function in these patients. The purpose of this study was to assess renal function after resection of right renal cell carcinoma (RCC) with obstructing IVC TT and the possible risks that may arise after left renal vein division.
