Blue Dye Embolization of Renal Tumor: A New Technique to Improve Tumor Localization During Laparoscopic Partial Nephrectomy.

To improve the tumor localization during laparoscopic surgery, we describe an innovative technique involving superselective intra-arterial injection of blue dye in tumoral vessels to color the tumor before surgical enucleation. The dye injection was performed at the same time as superselective embolization, immediately before laparoscopic surgery in a hybrid operating room. We used this new treatment sequence on 50 consecutive patients.

Pneumococcal urinary antigen test: A tool for pneumococcal aortitis diagnosis?

Introduction: Aortitis is rare. The etiological diagnosis is difficult but essential for treatment. Even with appropriate treatment mortality remains high.

Laparoscopic partial nephrectomy following tumor embolization in a hybrid room. Feasibility and clinical outcomes.

Purpose: In order to limit ischemia and operative bleeding during and after partial nephrectomy we developed a clampless laparoscopic technique, in a hybrid operating room, immediately after super-selective arterial embolization of the renal tumor. We evaluated feasibility and morbidity of this new approach of zero ischemia in partial nephrectomy.

Methods: We included prospectively 50 consecutive patients treated in a hybrid operating room by this new technique for a localized renal tumor in a university hospital between May 2015 and January 2017.
