Salvage Retzius sparing robotic assisted radical prostatectomy: the first brazilian experience.

Introduction:: Salvage Radical Prostatectomy after radiation therapy is challenging and associated with high rates of serious complications (1, 2). The novel Retzius-Sparing RARP (RS-RARP) approach has shown excellent continence outcomes (3, 4).

Purpose:: To describe step-by-step our Salvage Retzius-Sparing RARP (sRS-RARP) operative technique and report feasibility, safety and the preliminary oncological and continence outcomes in the post-radiation scenario.

Videoendoscopic gracilis muscle flap (VEGMF): A new minimally invasive technique for rectovesical fistula closure.

Fistulas between the rectum and the bladder have different etiologies, they may be congenital, acquired, or iatrogenic. Symptoms such as pneumaturia, fecaluria, and the passage of urine through the rectum are often alleviated by fecal and urinary diversion. The interposition of a flap of gracilis muscle is a technique that is very successful, but the conventional dissection of this flap involves a very large incision and a worse aesthetic result

Robotic-assisted surgical removal of retroperitoneal schwannoma by transmesocolic access.

Introduction:: Schwannoma are usually benign tumors, most of the cases are asymptomatic, and others may present symptoms by compression. In the literature robotic surgery were described in 8 cases. We emphasize that robotic surgery improves visualization and enable the performance of this procedure.

Promising pharmacological profile of a Kunitz-type inhibitor in murine renal cell carcinoma model.

Renal cell carcinoma (RCC), also called kidney cancer or renal adenocarcinoma, is highly resistant to current treatments. It has been previously reported that a Kunitz-type inhibitor domain-containing protein, isolated from the salivary glands of the Amblyomma cajennense tick, triggers apoptosis in murine renal adenocarcinoma cells (Renca) by inhibiting the proteasome and endoplasmic reticulum stress. Of note, Amblyomin-X is the corresponding recombinant protein identified in the cDNA library from A.
