Evaluation of a minimally invasive renal cooling device using heat transfer analysis and an in vivo porcine model.

Partial nephrectomy is the gold standard treatment for renal cell carcinoma. This procedure requires temporary occlusion of the renal artery, which can cause irreversible damage due to warm ischemia after 30 min. Open surgical procedures use crushed ice to induce a mild hypothermia of 20°C in the kidney, which can increase allowable ischemia time up to 2.

Significance of prostate weight on peri and postoperative outcomes of robot assisted laparoscopic extraperitoneal radical prostatectomy.

Introduction: To determine the significance of prostate weight (PW) on clinical and pathological outcomes in patients undergoing da Vinci robot assisted laparoscopic extraperitoneal radical prostatectomy (EP-RARP).

Methods: From November 2008 to January 2010, 295 men underwent EP-RARP at our institution. We retrospectively reviewed our database and stratified patients into four groups based on pathologic PW: Group 1, less than 30 g; Group 2, 30 g to less than 50 g; Group 3, 50 g to less than 80 g; and Group 4, 80 g or larger.

Assessment of critical renal ischemia with real-time infrared imaging.

Background: Currently visual and tactile clues such as color, mottling, and tissue turgor are used in the operating room for subjective assessments of organ ischemia. Studies have demonstrated that infrared (IR) imaging is a reliable tool to identify perfusion of brain tumors and kidneys during human surgery. Intraoperative IR imaging has the potential for more objective real-time detection and quantitative assessment of organ viability including early ischemia.

Treatment of bladder cancer in cardiac transplant patients.

We report a patient who presented with superficial bladder tumors 8 years after cardiac transplantation. He was managed conservatively with intra-vesical therapy for 5 years and ultimately underwent a successful radical cystoprostatectomy and urethrectomy 13 years after cardiac transplantation. This illustrates that cardiac transplant patients with superficial tumors may be managed with conservative therapies, but close vigilance is necessary to identify the opportune time for extirpative surgery.

Successful outpatient management of the nonpalpable intra-abdominal testis with staged Fowler-Stephens orchiopexy.

Purpose: Previous reports of orchiopexies have shown an 85.9% success rate for staged Fowler-Stephens orchiopexy (FSO). We review our experience with nonpalpable testes (NPTs).
