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...

BACKGROUND: Although renal graft percutaneous embolization was introduced to avoid the risk associated with graft nephrectomy, there is no universal consensus about its indications and results. OBJECTIVE: Evaluate the efficacy of graft embolization in the treatment of graft intolerance syndrome as well as its safety compared to surgical removal with respect to complications and other morbidity measures. MATERIALS AND METHODS: A retrospective observational study comparing 2 groups of patients treated for graft intolerance syndrome: Group 1: patients who had embolization as first line treatment and Group 2: patients directly treated by surgical removal...

BACKGROUND: In animal studies, remote ischemic preconditioning (RIPC) and anesthetic preconditioning are successful in reducing renal ischemia reperfusion injury (IRI), however the protective effect of RIPC may be improved by repeating the RIPC stimulus. METHODS: Sprague-Dawley rats underwent unilateral nephrectomy followed by 30 min of renal pedicle clamping. Animals were allocated into six groups: sham, control (IRI), RepISO (daily isoflurane anesthesia), RIPC (single dose isoflurane anesthesia and single dose RIPC), RepISO + RIPC (7-day isoflurane anesthesia and single dose RIPC) and RepISO + RepRIPC (7-day isoflurane anesthesia with 7-day RIPC)...

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...

REVIEW
K Farrag, S Sriprasad
A large number of small renal masses (SRMs) with size less than 4 cm are being identified due to advances in diagnostic imaging. As the natural history of these tumours remains unknown, there is no reliable way to predict their behaviour or future growth. Although, partial nephrectomy is the gold standard for treatment of these tumours, ablative non-surgical therapies such as cryoablation and radiofrequency ablation provide a less invasive option of treatment with comparable oncological outcomes. In this systematic review, the principle, indications, methods of treatment, oncological control, complication and renal function of ablative therapies are critically reviewed...

BACKGROUND: Isolated renal allograft aspergillosis is rare and usually presents with fever and decreased glomerular filtration rate. Presentation with obstructive uropathy caused by aspergillus fungal balls is much less common. We report a young male patient who presented with obstructive uropathy secondary to isolated renal allograft aspergillus infection 6 weeks after transplant. He was treated with nephrectomy and antifungal medications. CASE PRESENTATION: A 29-year-old Saudi male patient had a recent living non-related kidney transplantation in Pakistan...

BACKGROUND: A shortage of donors poses a serious problem for organ transplantation around the world. In response, the concept of the expanded criteria donor (ECD) has been defined to include donors with traditionally less favorable characteristics. That definition has now been accepted and is being applied in kidney transplantation in the United States and Europe. However, the ECD has not yet been defined for deceased donor kidney transplantation in Japan. PATIENTS AND METHODS: We analyzed data on graft survival and relevant risk factors in patients who received deceased donor kidney transplants through the East Japan Branch of the Japan Organ Transplant network (n = 1051)...

Tubulointerstitial fibrosis is recognized as a key determinant of progressive chronic kidney disease (CKD). Fucoidan, a sulphated polysaccharide extracted from brown seaweed, exerts beneficial effects in some nephropathy models. The present study evaluated the inhibitory effect of oligo-fucoidan (800 Da) on renal tubulointerstitial fibrosis. We established a mouse CKD model by right nephrectomy with transient ischemic injury to the left kidney. Six weeks after the surgery, we fed the CKD mice oligo-fucoidan at 10, 20, and 100 mg/kg/d for 6 weeks and found that the oligo-fucoidan doses less than 100 mg/kg/d improved renal function and reduced renal tubulointerstitial fibrosis in CKD mice...

BACKGROUND: The aim of this study was to investigate the incidence of benign histology after partial nephrectomy (PN) in patients with presumed malignancy from preoperative imaging. Furthermore, preoperative predictors of benign lesions and perioperative outcomes were also assessed. METHODS: A series of patients undergoing PN for renal masses was identified using a prospectively maintained database. Patients were excluded for known genetic conditions, if more than one renal mass was resected, or if standard preoperative imaging was not suspicious for renal-cell carcinoma (RCC)...

OBJECTIVE: To evaluate whether excised parenchymal mass (EPM) during partial nephrectomy (PN) correlates with functional decline and can serve as a surrogate for functional outcomes. MATERIALS AND METHODS: All 215 patients managed with PN for unifocal renal mass with necessary studies to determine EPM and percent glomerular filtration rate (GFR) and parenchymal mass preserved (both global and specific to the operated kidney) were analyzed. EPM was estimated from the pathologic specimen by subtracting the tumor mass from specimen mass, with both calculated using the elliptical formula...

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...

INTRODUCTION: The introduction of the robotic surgical platform has led to distinct changes in practice patterns and the utilization of minimally invasive surgery in urology. While use of the robotic system is associated with improvements in perioperative outcomes such as estimated blood loss and hospital stay, there are significant fixed and variable costs with the purchase, maintenance and use of the robotics system that has led many authors to investigate the cost effectiveness of robotic urologic surgery...

REVIEW
Kevin Cwach, Louis Kavoussi
Although laparoscopic renal surgery dates to almost 30 years ago, in which the first laparoscopic nephrectomy was performed in 1990, the history of laparoscopy extends back over 100 years, when laparoscopy was first performed on dogs. Over the last 30 years, laparoscopic renal surgery has seen many advancements in technology and technique. With the introduction of robotics and new instruments, renal surgery is becoming increasingly less invasive, and patients are having improved operative outcomes. As new technology develops, the envelope will continue to be pushed by urologists with the hope of improvement of patient outcomes and satisfaction...

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...
