[Venous thromboembolism prophylaxis in Colombian surgical and medical patients: results for Colombia of the ENDORSE study].

Introduction: More information is needed on the risk of venous thromboembolism in the hospital setting, and on patterns of use of thromboprophylaxis, as advocated in consensus guidelines. ENDORSE was an international study aimed at evaluating hospital venous thromboembolism prevention practices in medical and surgical patients.

Objectives: The risk of venous thromboembolism was evaluated along with the use of thromboprophylaxis in hospitalized medical and surgical subjects; these data were compared with the international sample from the ENDORSE study.

Does prolonged pneumoperitoneum affect oxidative stress compared with open surgical procedures?

Background And Purpose: As laparoscopic surgery has evolved, it has become part of the urologic surgical armamentarium and is now used to perform more complex procedures. Carbon dioxide, used to create pneumoperitoneum, produces physiologic changes in various organs, including the kidneys. Such changes are associated with altered redox status because of the release of free radicals and changes in oxidative stress signals.

Use of the LigaSure vessel sealing device in laparoscopic living-donor nephrectomy.

Background: Laparoscopic living-donor nephrectomy has gained acceptance within the transplant community. The technique requires advanced laparoscopic techniques, and great care must be taken to ensure safety of the operation for the donor and transplantability of the donor kidney. Minimizing the risk of bleeding and trauma to the kidney are important features of a successful living-donor nephrectomy.

Laparoscopic partial nephrectomy of solid renal masses without hilar clamping using a monopolar radio frequency device.

Purpose: Partial nephrectomy is currently recommended for most amenable solid renal tumors, especially if they are exophytic and less than 4 cm. We reviewed our initial experience with laparoscopic partial nephrectomy for solid renal masses without clamping the renal vasculature using a monopolar device that uses radio frequency energy with low volume saline irrigation for simultaneous blunt dissection, hemostatic sealing and coagulation of the renal parenchyma (TissueLink, TissueLink Medical, Inc., Dover, New Hampshire).

Extramedullary plasmacytoma invading the bladder: case report and review of the literature.

Multiple myeloma is characterized by neoplastic proliferation of a single clone of plasma cells engaged in the production of a monoclonal protein. This condition affects mainly the bone marrow, but extramedullary manifestations can be seen in any organ. Urinary bladder involvement is extremely rare, with only 14 cases reported in the literature to our knowledge.
