Indications and Limitations of Coverage and/or Medical Necessity Retroperitoneal ultrasound studies represent the ultrasonic imaging of retroperitoneal organs for the diagnosis and management of abnormalities that occur in the retroperitoneum. We describe our experience with laparoscopic retroperitoneal lymph node dissection in 26 patients with nonseminomatous germ cell tumors: 17 had stage I disease with no clinical (computerized tomography, ultrasound or tumor markers) evidence of metastases and 9 (2 with stage IIb and 7 with stage IIc disease) had residual tumor after chemotherapy but with negative tumor markers. The ultrasound depicts the local soft-tissue edema, indicates the formation of the abscess by showing a fixed hypoechoic area, and measures the size of abscess as well as helps in determining the location of the abscess. Intraoperative procedure: Under fluorescent laparoscopic surveillance, an ultrasound scalpel was used to separate the retroperitoneal space to avoid incision of the peritoneum and to locate the right posterior lobe of the liver.
