CONTEXT: Spontaneous forniceal rupture is one of the possible complications of urolithiasis. The mechanism of forniceal rupture is not well explained in the literature. Most of the cases presented with sudden onset of acute renal colic and diagnosed by noncontrast CT (NCCT). Until now there is no solid consensus about the ideal management of such a condition. AIM: To study indications and validity of conservative management of spontaneous caliceal rupture. SETTINGS AND DESIGN: This is an observational prospective study...

The stomach is the preferred augmentation option for a contracted bladder in a patient with renal failure. A 49-year-old female presented with right solitary functioning kidney with tuberculous lower ureteric stricture and contracted bladder. Her creatinine was 2.8 mg%. By laparoscopic approach, right gastroepiploic artery based gastric flap was isolated using staplers and used for augmentation and ureteric replacement. At 6-month follow-up, her creatinine was 1.9 mg%, and bladder capacity was 250 ml. She had mild hematuria, which settled with proton pump inhibitors...

Metastases in the paranasal sinuses are rare; renal cell carcinoma is the most common cancer that metastasizes to this region. We present the case of a patient with a 4-month history of a rapidly growing mass of the nasal pyramid following a nasal trauma, associated with spontaneous epistaxis and multiple episodes of hematuria. Cranial CT scan and MRI showed an ethmoid mass extending to the choanal region, the right orbit, and the right frontal sinus with an initial intracranial extension. Patient underwent surgery with a trans-sinusal frontal approach using a bicoronal incision combined with an anterior midfacial degloving; histological exam was compatible with a metastasis of clear cell renal cell carcinoma...

Congenital abnormalities of the kidney and urinary tract (CAKUT) are one of the leading congenital defects to be identified on prenatal ultrasound. CAKUT represent a broad spectrum of abnormalities, from transient hydronephrosis to severe bilateral renal agenesis. CAKUT are a major contributor to chronic and end stage kidney disease (CKD/ESKD) in children. Prenatal imaging is useful to identify CAKUT, but will not detect all defects. Both genetic abnormalities and the fetal environment contribute to CAKUT. Monogenic gene mutations identified in human CAKUT have advanced our understanding of molecular mechanisms of renal development...

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...

Hyperfiltration is a well-known risk factor in progressive loss of renal function in chronic kidney disease (CKD) secondary to various diseases. A reduced number of functional nephrons due to congenital or acquired cause(s) results in hyperfiltration in the remnant kidney. Hyperfiltration-associated increase in biomechanical forces, namely pressure-induced tensile stress and fluid flow-induced shear stress (FFSS) determine cellular injury and response. We believe the current treatment of CKD yields limited success because it largely attenuates pressure-induced tensile stress changes but not the effect of FFSS on podocytes...

BACKGROUND: Successful pancreas transplantation requires surgical expertise and multidisciplinary medical management. The impact of transplant center volume on pancreas allograft survival remains unclear. METHODS: We examined Organ Procurement and Transplantation Network (OPTN) data on 11,568 simultaneous pancreas-kidney (SPK) and 4308 solitary pancreas (pancreas transplant alone and pancreas after kidney) transplants between 2000 and 2013. RESULTS: Average annual transplant center volume was categorized by tertiles into low, medium and high volume, respectively, as follows: 1-6 (n=3,861), 7-13 (n=3,891), and 14-34 (n=3,888) for SPK, and 1-3 (n=1,417), 4-10 (n=1,518), and 11-33 (n=1,377) for solitary pancreas transplants...

A 1-year-old male infant presented with fever and abdominal lump for 3 months with increased leucocyte count (15 300/mm(3)) and serum creatinine (0.83 mg%). Abdominal ultrasound and renal scan demonstrated solitary left kidney with dilated tortuous left ureter. Voiding cystourethrogram was unequivocal. Left percutaneous nephrostomy was placed after poor response to perurethral catheterisation. His serum creatinine dropped to 0.58 mg/dL. Subsequent percutaneous nephrostogram and CT nephrostogram showed dilated left pelvicalyceal system, dilated, tortuous left ureter...

De novo donor-specific antibody (dnDSA) is associated with antibody-mediated rejection (AMR) and allograft loss, yet the allograft histology associated with dnDSA remains unclear. The aim of this study was to examine the allograft histology associated with dnDSA in patients with serial surveillance biopsies. We retrospectively studied adult conventional solitary kidney transplant recipients from October 2007 to May 2014. The definition of dnDSA was new donor-specific antibody (DSA) with mean fluorescence intensity (MFI) >1000...

INTRODUCTION: Hilar clamping is often performed to facilitate robotic partial nephrectomy (RPN). Minimal clamping techniques may reduce renal ischemia, including early unclamping, selective clamping, and off-clamp RPN. We assess the utilization of clamping techniques in a large international consortium of surgeons performing RPN for complex tumors. METHODS: We retrospectively evaluated 721 patients with complex tumors, who underwent RPN at 11 centers worldwide between 2008 and 2014...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...

Metastasis of renal cell carcinoma (RCC) to urinary bladder is extremely rare. We report a case of metastasis arising from RCC to the urinary bladder 7 years after treatment of bilateral RCC. A 74-year-old man was diagnosed with bilateral multiple renal tumors (T1aN0M1, PUL, OSS) with two lesions in the right kidney and a solitary lesion of the left kidney in 2008. He underwent laparoscopic radical nephrectomy for the right side in September 2008. The next month, ex vivo partial nephrectomy and auto-transplantation was performed for the left kidney because the tumor was located very close to the collecting system...

AIMS: To study the intermediate term to long-term functional status of kidneys with split renal function(SRF) <15% secondary to PUJO which are preserved by pyeloplasty and to find out whether these kidneys can recover or eventually need nephrectomy. METHODS: 24 patients with SRF<15% and undergoing pyeloplasty with or without prior percutaneous nephrostomy (PCN) were studied. Those with associated VUR, B/L disease and redo pyeloplasties were excluded. Follow up USG and EC scan were done at 3, 9 and 18months and yearly thereafter to document functional status after surgery...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...
