retroperitoneal fibrosis (rpf) is a rare condition with an unclear etiology, presenting with the development of aberrant chronic nonspecific fibroinflammatory tissue in the retroperitoneal space, which can result in entrapment and obstruction of the retroperitoneal structures. rpf is a subtype of chronic periaortitis, and can be divided into two types: primary (or idiopathic) and secondary. rpf...

PURPOSE To present the oncologic and functional outcomes of robot-assisted partial nephrectomy (RAPN) and analyze retroperitoneal and transperitoneal approaches. PATIENTS AND METHODS RAPN was performed on 103 patients; 44 patients underwent a retroperitoneal and 59 a transperitoneal approach. Demographic, operative, and postoperative data was collected and retrospectively analyzed on all pati...

If a testicular cancer patient has a mass in the retroperitoneum, a metastasis is often the first suspicion, probably leading to improper diagnosis and overtreatment. Here we report a case of retroperitoneal schwannoma mimicking metastatic seminoma. A 29-year-old man, who had a history of seminoma, presented with a single retroperitoneal mass suspected to be a metastasis. Because the patient re...

Background. The concomitant occurrence of a renal cell carcinoma and retroperitoneal sarcoma is extremely rare with only few cases being reported. Methods. We present a case of simultaneous renal cell carcinoma and exceptionally large size retroperitoneal sarcoma involving small intestine. Surgical resection of retroperitoneal sarcoma and simultaneous right nephrectomy were performed. Results. ...

bronchogenic cysts are among developmental disorders of the primitive foregut which are typically found above the diaphragm. bronchial cysts discovered in the abdominal cavity or retroperitoneum are extremely rare. we present a rare case of a retroperitoneal bronchogenic cyst which was incidentally detected after a wrestling injury in a 23-year-old man who had a negative medical history. althou...

Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of r...

BACKGROUND By clarifying the significance of clinicopathological factors for retroperitoneal lymph node metastasis and survival of patients with endometrial cancer, we suggest ideas for optimal treatment of this disease. METHODS A retrospective study was conducted in 310 women with endometrial cancer who underwent surgery with retroperitoneal lymphadenectomy. To evaluate retroperitoneal lymph...

INTRODUCTION AND OBJECTIVE Retroperitoneal access for robotic renal surgery is an effective alternative to the commonly used transperitoneal approach. We describe our contemporary experience and technique for attaining retroperitoneal access. MATERIALS AND METHODS We outline our institutional approach to retroperitoneal access for the instruction of urologists at the beginning of the learning...

Retroperitoneal sarcomas (RPS) are rare malignant tumours that originate from connective tissues of skeletal or extraskeletal origin in the retroperitoneal region, which often missed. This case report highlights a patient with RPS presented abdominal swelling. In addition, this was written to elucidate significance thorough history, physical examination findings, and awareness considering as di...

BACKGROUND Recent studies have demonstrated that pathological analysis of retroperitoneal residual masses of patients with testicular germ cell tumors revealed findings of necrotic debris or fibrosis in up to 50% of patients. We aimed at pursuing a clinical and pathological review of patients undergoing post chemotherapy retroperitoneal lymph node dissection (PC-RPLND) in order to identify vari...
