Wünderlich's syndrome is a spontaneous nontraumatic massive retroperitoneal hemorrhage. It is usually secondary to a renal neoplasm, with angiomyolipoma being the most frequent followed by renal cell carcinoma. The management of spontaneous retroperitoneal bleeding varies depending on the hemodynamic status of the patient. We present the first report of a transperitoneal laparoscopic nephrectom...

Here we report a case of idiopathic retroperitoneal fibrosis, a unilateral case, which resulted in remission by ureterolysis with intraperitonealization. A 24-year-old female was hospitalized because of hydronephrosis. Many examinations were performed with the suspicion of malignant disease, but no apparent cause was detected. We suspected idiopathic retroperitoneal fibrosis and performed surgi...

BACKGROUND There is no standard surgical approach for the management of retroperitoneal sarcoma. The aim of this clinical study was to describe the experience of an anterior approach to en bloc resection in left-sided retroperitoneal sarcoma with adjacent organ involvement. MATERIAL AND METHODS This retrospective clinical study included 25 patients who were diagnosed with left-sided retroperito...

BACKGROUND There is little knowledge on retroperitoneal sarcoma, but there are many controversies. The objective of the current study was to define the common and distinctive features of primary and secondary retroperitoneal sarcomas in terms of presentation, prognostic and therapeutic approach to improve the current management of these tumors. Vascular involvement impact was assesed in the two...

Retroperitoneal leiomyoma is a rare benign smooth muscle tumor almost exclusively found in women and with histopathological features similar to uterine leiomyomas. The pathogenesis of retroperitoneal leiomyoma is unclear and next to nothing is known about the cytogenetics and molecular genetics of the tumor. We present here a retroperitoneal leiomyoma with a t(9;22)(q33;q12) as the sole karyoty...

OBJECTIVE To report our experience of retroperitoneoscopic technique in semi-lateral decubitus position for the retroperitoneal nonadrenal ganglioneuromas in 18 patients, and to evaluate its clinical outcomes. MATERIALS AND METHODS From January 2012 to May 2016, 18 patients with retroperitoneal nonadrenal ganglioneuromas underwent retroperitoneoscopic resection. With the patients in semi-late...

Foreign bodies are rare and challenging issues leading to symptoms according to the location. Laparoscopy is a popular and minimally invasive method used for removal of foreign bodies in the abdominal cavity or retroperitoneum. We herein report a case with retroperitoneal foreign body that was removed through retroperitoneal single- port laparoscopy using nephroscope. To our knowledge this is t...

background: giant retroperitoneal uterine leiomyomas are uncommon. degenerative changes of a leiomyoma may lead to unusual presentation resulting in misdiagnosis preoperatively. the final diagnosis can be made either intraoperatively or histologically. case: we report a 45-year-old multiparous women presented with abdominal distension and fatigue for six months. abdominopelvic sonography and co...

Necrotizing fasciitis is one of the uncommon presentations of a rapidly spreading subcutaneous tissue infection. Although the actual cause is unclear in many cases, most of them are due to the rapid proliferation of microorganisms. Retroperitoneal necrotizing fasciitis is extremely rare. It is a potentially lethal infection that requires immediate and aggressive surgical care. Early diagnosis i...

We report the case of a large lumbar schwannoma eroding the vertebra and originating from spinal canal with invasion of the retroperitoneal space. We also review all the cases in literature reporting lumbar schwannomas eroding the vertebral bodies and invading the retroperitoneal space focusing on the surgical strategies to manage them. Spinal CT-scan revealed a 44 mm × 55 mm inhomogeneous soft...
