BACKGROUND: Myxomas are rare benign soft tissue tumors. The kidney is an unusual location for this tumor. For this reason, less than 15 cases of renal myxoma have been reported in the English literature. There are no specific clinical and radiological features reported for this tumor that allow a preoperative diagnosis enabling a conservative treatment. CASE PRESENTATION: We report another case of renal myxoma found in a 50-year-old Moroccan woman who presented with a right dull flank pain...

INTRODUCTION AND OBJECTIVES: Robotic assisted radical cystectomy (RARC) is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. MATERIALS AND METHODS: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008...

BACKGROUND: Inferior vena cava repair after planned and unplanned venotomy is performed by either interposition bypass, patch venopasty, or lateral venorrhaphy and primary repair. Primary repair of the inferior vena cava avoids the use of foreign material and allows an all-autologous repair in an expeditious fashion. The purpose of this study was to demonstrate the utility of inferior vena cava repair, determine the degree of inferior vena cava stenosis, and examine clinical outcomes after primary repair...

The CIC-DUX4 sarcoma is a subset of the undifferentiated small round cell sarcoma family, presently recognized as a new clinicopathological entity. It is a rare and highly aggressive tumor usually arising in the soft parts of the limbs and the trunk. Only a very few cases of primitive visceral CIC-DUX4 have been hitherto described. We report the case of a 29 year-old male patient with a primary CIC-DUX4 sarcoma of the kidney with lung metastasis. The outcome of the disease was rapidly unfavorable. Despite radical nephrectomy, the patient experienced an early local retroperitoneal recurrence associated with lung and liver metastases...

INTRODUCTION: We investigated the prognostic significance of the neutrophil-to-lymphocyte ratio on tumor stage and Fuhrman nuclear grade in renal cell carcinoma. METHODS: The records of 432 patients with RCC who underwent radical or partial nephrectomy between 2005 and 2014 were retrospectively reviewed. Patients were classified as group lower tumor stage(T1 + T2) and higher(T3 + T4). As like tumor stage, Fuhrman nuclear grade were classified lower (G1+G2) and higher(G3+G4) too...

Collecting duct carcinoma (CDC), which is also known as Bellini duct carcinoma, accounts for less than 1% of all renal cell carcinoma, which has a poor prognosis. Predominantly, clinicians recognize this disease due to past experience and case reports, and a standard treatment is yet to be established. The present case report describes a 57-year-old male patient with CDC who was successfully treated with a left laparoscopic radical nephrectomy without any adjuvant therapy and compares the present patient's clinical presentation with previously reported cases...

BACKGROUND: Robotic single-site retroperitoneal renal surgery has the potential to minimize the morbidity of standard transperitoneal and multiport approaches. Traditionally, technological limitations of non-purpose-built robotic platforms have hindered the application of this approach. OBJECTIVE: To assess the feasibility of retroperitoneal renal surgery using a new purpose-built robotic single-port surgical system. DESIGN, SETTING, AND PARTICIPANTS: This was a preclinical study using three male cadavers to assess the feasibility of the da Vinci SP1098 surgical system for robotic laparoendoscopic single-site (R-LESS) retroperitoneal renal surgery...

Ureter tumor thrombus (TT) of renal cell carcinoma (RCC) is quite rare, although RCC-TT in the inferior vena cava (IVC) is not uncommon. We report the first case of RCC-TT extending into the IVC and ovarian vein as well as the ureter. Neoadjuvant axitinib shrank both the primary tumor and TT, making radical nephrectomy less invasive, particularly by downleveling the IVC-TT. Pathological examination of the primary tumor, IVC-TT, and ureter TT showed clear cell carcinoma with extensive necrosis. Although the role of neoadjuvant axitinib in RCC remains unclear, the present case suggests that neoadjuvant axitinib is clinically beneficial for RCC-TT...

Solitary fibrous tumor (SFT) of the kidney is a rare entity and usually displays a favorable prognosis. We herein report a second case of renal SFT developing local recurrence. A 50-year-old man was referred to our hospital because of a left renal mass. An abdominal CT detected a large renal tumor and radical nephrectomy was performed with a possible diagnosis of renal cell carcinoma. The resected tumor size was measured at 17 × 11 × 8 cm. Grossly, necrosis was observed in central lesion of the tumor but hemorrhage was not observed...
