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 10/2007-5/2014. DnDSA was new DSA with MFI >1000. The incidence of dnDSA was 7.0%(54/771) over mean follow-up of 4...

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. Complex tumors were defined as renal masses with a nephrometry score > 6...

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...

Renal angiomyolipoma is a rare benign tumour and its occurrence during pregnancy is even rare. It is usually diagnosed incidentally. It can increase in size during pregnancy and can present acutely as rupture with retroperitoneal haemorrhage, mechanism of which is still unclear. We present a case of successful pregnancy outcome in a patient with congenital solitary kidney affected by angiomyolipoma, diagnosed incidentally at 19 years of age. The patient had conceived twice. Her antenatal and post partum period was uneventful both the times...

This review article explores sports and recreational precautions in children with solitary kidneys. In 2001, the American Academy of Pediatrics published recommendations for activity in children with medical conditions. Those with solitary kidneys were graded a "qualified yes": no restriction in noncontact sports, and individual assessment for limited-contact, contact, and collision sports. Recent trauma data suggest that classification according to the degree of contact is inaccurate. We propose an updated, data-driven classification of sports or recreation according to the risk of high-grade renal trauma or loss of renal unit...

The number of new cases of renal cell carcinoma has been steadily increasing since the 1960s, reaching 62,000 and 89,000 annually in the United States and Europe, respectively, in 2016. The current standard of care for early-stage disease is nephron-sparing surgery, which has a demonstrated long-term disease-free survival and an acceptable safety profile. Technical developments (thin, powerful probes and real-time image guidance systems) have allowed image-guided percutaneous ablation to become a viable option for stage I renal cell carcinoma...

Background Combined liver-kidney transplantation (CLKT) is well-established as a definitive therapy with the potential to provide complete recovery for certain liver-kidney diseases, although the results might be contingent on the cause of transplantation. The purposes of the present study were to review the long-term outcome of renal allografts in CLKT patients from single living donors and to investigate the beneficial factors, compared with solitary renal transplantation. Materials and Methods Thirteen patients underwent sequential liver (LTx) and kidney (KTx) transplantations from single living donors...

Stones in solitary kidney represent a management dilemma for the endourologist. The advantage of bilateral fully functioning kidneys is not present. Therefore, any insult to either the solitary kidney itself or drainage system can lead to significant morbidity. Key clinical objectives include maximum preservation of existing renal function, high stone clearance, and minimizing post-procedure complications. To date, there exists no Level 1 evidence on this subject. This systematic review serves to evaluate the safety and efficacy of percutaneous nephrolithomy for patients (adults only) with stones in a solitary kidney...

INTRODUCTION: Primary hyperparathyroidism (pHPT), most commonly caused by solitary parathyroid adenomas, leads to mobilization of calcium and is known to result in nephrolithiasis and osteoporosis. To date, studies of pHPT and cardiovascular risk factors and events have produced discrepant findings, likely due to small sample sizes and enrolling populations with varying disease severity. HYPOTHESIS: We utilized a national registry, hypothesizing an association between pHPT and cardiovascular risk factors and events...
