OBJECTIVES To investigate our case series of patients with primary retroperitoneal tumors over the past 10 years, analyzing clinical symptoms, diagnostic tests, tumor pathology, surgical data, concomitant cancer treatments, recurrence and survival rates. METHODS Retrospective analysis of 37 patients with primary retroperitoneal tumors diagnosed at our hospital over the past 10 years. RESULT...

BACKGROUND The origin of extragonadal retroperitoneal germ cell tumors remains controversial. Whether they develop primarily in the retroperitoneum or whether they are metastases of a primary testicular tumor has long been debated. PATIENTS AND METHODS We retrospectively analyzed 26 patients treated as having primary extragonadal retroperitoneal germ cell tumors based upon the findings of tes...

We describe a 48-year-old woman with ruptured retroperitoneal mucinous cystadenoma with borderline malignancy resulting in death for postoperative intestinal compression. The patient was referred to our institution for abdominal mass with preoperative ultrasonography and computed tomography (CT) revealing retroperitoneal mass. At operation, the 12×9 cm retroperitoneal tumor had ruptured. Tumor ...

INTRODUCTION Retroperitoneal fibrosis is a rare disease. It can be primary (Ormond's disease) or secondary to inflammation, malignancy or some drugs. Beta-adrenergic blockers including propranolol can cause the retroperitoneal fibrosis disease. CASE A 44-year-old woman who was taking propranolol for 13 years came to our center with complaints of oliguria and uremia symptoms (malaise, nausea a...

Retroperitoneal fibrosis (RPF) is a relatively rare disease which shows a periaortic mass in the retroperitoneal area and predisposes to an obstructive uropathy. We report a case of idiopathic RPF occurring in a patient who was suspected of impending rupture of abdominal aortic aneurysm. A 60-year-old male, with a 2-week history of abdominal pain, was transferred for evaluation of the periaorti...

PURPOSE To compare perioperative outcomes, specifically hospital length of stay (LOS), after retroperitoneal and conventional transperitoneal robot-assisted partial nephrectomy (RAPN). PATIENTS AND METHODS We retrospectively compared consecutive patients with a posterior renal mass undergoing retroperitoneal RAPN (n=116) versus transperitoneal RAPN (n=97) at our institution between July 2007 ...

A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC). The tumor size was 55 × 58 mm, and ...
