INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

Hyperkalemia is an important complication of adrenalectomy for patients with primary aldosteronism (PA). The frequency of hyperkalemia after medication using mineralocorticoid receptor antagonists (MRAs) for PA is unclear. The aim of this study is to investigate the frequency and the risk factors of hyperkalemia after surgery and medication for PA. The data of 376 patients with PA registered in a multicentre-collaborative study in Japan, including surgically treated patients (group A; n=142) and medically treated patients with MRAs (group B; n=234) were studied...

Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis...

Objective To compare the surgical outcomes between resection and enucleation in robot-assisted laparoscopic partial nephrectomy (RAPN) based on the Surface-Intermediate-Base margin score (SIB score). Patients and Methods This study included 282 patients who underwent RAPN between 2014 and 2016. SIB score was macroscopically evaluated immediately after the surgery. We divided the patients into the following two groups: enucleation (SIB score, 1-2) and resection (SIB score, 3-5). To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching...

The most frequent ureteral lesions are iatrogenic, mainly due to gynecologic and urologic procedures. The resolution and repair of these lesions, when they require surgery, is often the performance of ureteroneocystostomy. We describe the technique for the repair of distal ureter lesions that preserves both anatomy and function of the urinary tract (1). The operation consists in dissection and extraction of the distal ureteral stump from its intramural tract to get at least 1 cm of free ureter, percutaneous insertion of a ureteral stent, checking the absence of tension between proximal ureter and distal dissected stump, end to end anastomosis and reinsertion of the distal ureter in the previously dissected bladder muscle layer...

OBJECTIVES: Laparoscopic ureteral reconstructive surgery is routinely performed , because it demonstrated efficacy and safety profiles similar to open surgery in expert hands. The most frequent surgical complications after transplant are urological, appearing in up to 12,5% of the cases; they can compromise graft function and mortality. The most frequent ones include ureterovesical anastomosis stenosis (2,5-7,5%) and vesicoureteral reflux (0,4-2,2), which present in up to 80% of the cases...

BACKGROUND: A significant proportion of patients with chronic kidney disease and secondary hyperparathyroidism (HPT) remain hyperparathyroid after kidney transplantation, a state known as tertiary HPT. Without treatment, tertiary HPT can lead to diminished kidney allograft and patient survival. Parathyroidectomy was commonly performed to treat tertiary HPT until the introduction of the calcimimetic drug, cinacalcet. It is not known whether surgery or medical treatment is superior for tertiary HPT...

Wilms tumour is named after Max Wilms. It is an embryonal tumour derived from the metanephros. It is the commonest childhood renal tumour and the third commonest paediatric malignancy. Synchronous bilateral Wilms tumours (BWT) represent 4-7% of all Wilms tumours (WT) and present at a younger age than unilateral Wilms tumours. At least 10% of synchronous BWTs have unfavourable histology, and up to 22% are associated with genitourinary abnormalities, aniridia, WAGR syndrome, Denys-Drash syndrome, hemihypertrophy, or one of the other overgrowth syndromes...

Solitary metastasis of a carcinoma to carpal bone is extremely rare. Metastases of renal cell carcinoma (RCC) usually occur in a multiple fashion and there has been no report to date of a solitary metastasis to trapezium from RCC. The tumor was excised and reconstructed with iliac bone transplantation. 2 years and 6 months after surgery, there is no local recurrence with minimal functional loss.

Background.: Perioperative administration of cefazolin reduces the incidence of perioperative infections. Intraoperative re-dosing of cefazolin is commonly given between 2 and 5 h after the initial dose. This study was undertaken to determine whether intraoperative continuous infusions of cefazolin achieve better probability of target attainment (PTA) and fractional target attainment (FTA) than intermittent dosing. Methods.: Patients undergoing major surgery received cefazolin 2 g before surgical incision...

The long noncoding RNA HOTAIR promotes the development and progression of several tumors. Here, the clinical significance and role of HOTAIR in renal cell carcinoma (RCC) tumorigenesis were explored. The results showed that increased expression of HOTAIR predicted a poor prognosis of RCC after surgery. HOTAIR promoted RCC cell proliferation and growth in vitro and in vivo. The expressions of HOTAIR and Salvador homolog 1 (SAV1) were inversely correlated in clinical RCC samples. HOTAIR downregulated SAV1 by directly binding to the SAV1 protein and enhanced histone H3K27 methylation...

INTRODUCTION: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS: 202 non-diabetic patients with normal renal function (serum creatinine <1...

The postoperative management of patients immediately after liver transplantation requires knowledge of this complex surgery and the physiology that accompanies liver failure. A multidisciplinary approach to the care of these patients is essential in order to reduce postoperative complications and preserve function in the transplanted organ. By their nature, patients undergoing liver transplantation have complicated medical problems before surgery which must be borne in mind when managing them after surgery...

Background: A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. Case Presentation: A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position. The percutaneous tract was established by combined radiologic and sonographic guidance. The tract was dilated by balloon and a 24F Amplatz sheath was located. As complete clearance was not achieved because of a residual lower pole caliceal stone, a ureteral Double-J and a 20F nephrostomy were located for a second-look PCNL through the same tract after 7 days...

Radical nephrectomy is associated with a progressive decline in renal function. Clinical parameters in post-nephrectomy insufficiency were described but the impact of histopathologic vascular findings in the non-neoplastic kidney of nephrectomy specimen, has been poorly studied. Our aim was to evaluate whether the severity of atherosclerosis in non-neoplastic renal tissue predicts the evolution of glomerular filtration rate in patients undergoing total nephrectomy. Thirty-one non-donor patients with unilateral radical nephrectomy were included...

BACKGROUND: NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population...
