OBJECTIVE To verify the feasibility and safety of retroperitoneal laparoendoscopic single-site radical nephrectomy and assess the value of our proposed approach to search for renal artery. METHODS A total of 60 cases of retroperitoneal laparoendoscopic single-site radical nephrectomy were performed using our homemade single-port multi-channel device. An incision of 5-6 cm was cut forward from...

About 70% of leiomyosarcomas are found in the retroperitoneal space.(1) Extensive surgical resection for achieving complete removal and ...

Retroperitoneal schwannomas are rare, usually benign tumors that originate in the neural sheath and account for only a small percentage of retroperitoneal tumors. We report a case of a 34-year-old male presented to our department complaining of left abdominal mass and pain. An abdominal computed tomography (CT) scan showed a large retroperitoneal mass of 15 cm in diameter. Histopathological exa...

CASE PRESENTATION A 50-year-old Greek man, who was on a non-steroidal anti-inflammatory agent (nimesulide) for ankylosing spondylitis, presented with a right retroperitoneal hematoma combined with ...

Idiopathic retroperitoneal fibrosis (IRF) entirely confined to the pelvic cavity is an extremely rare clinical entity. Herein, is described the case of a 36- year old male who presented with clinical and imaging manifestations of a large pelvic tumor. Exploratory laparotomy revealed a large mass in the right pelvis originating from the retroperitoneal space, displacing the right iliac vessels, ...
