The aim of the present study was to analyze the risk factors for new-onset chronic kidney disease (CKD) in patients who have received a liver transplant. A total of 190 patients who underwent liver transplantation between March 2001 and January 2015 were followed up, and analyzed retrospectively. Sex, age, primary disease, preoperative laboratory findings (hemoglobin, albumin, creatinine and glomerular filtration rate), surgical approach, blood loss during the surgery and transfusion volume, postoperative complications, and the average levels of calcineurin inhibitors (CNIs) (from liver transplantation to the onset of CKD) were analyzed...

BACKGROUND: Infants with a body weight of less than 10 kg are often not considered to be suitable candidates for renal transplantation (RTx). The objective of this study was to evaluate this arbitrary weight threshold for pediatric RTx. METHODS: We conducted a multicenter, retrospective, match-controlled cohort study on infants weighing less than 10 kg at time of engrafting (low-weight group [LWG], n = 38) compared to a matched control group (n = 76) with a body weight of 10-15 kg, using data from the first 2 years post-transplant derived from the CERTAIN Registry...

BACKGROUND: We compared renal functional outcomes of robotic (RPN) and open partial nephrectomy (OPN) in patients with chronic kidney disease (CKD), a definite indication for nephron-sparing surgery. METHODS: A multicenter retrospective analysis of OPN and RPN in patients with baseline ≥ CKD Stage III [estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 ] was performed. Primary outcome was change in eGFR (ΔeGFR, mL/min/1.73 m2 ) between preoperative and last follow-up with respect to RENAL nephrometry score group [simple (4-6), intermediate (7-9), complex (10-12)]...

OBJECTIVE: Kidney tumors represent 2- 3% of adult tumors. Partial nephrectomy is the standard of care for the treatment of localized tumors. Minimizing ischemia time is critical for postoperative renal function. The aim of this paper is to present our experience in laparoscopic partial nephrectomy with selective renal parenchymal compression using the Simon clamp. METHODS: We analyzed the record of patients that underwent surgery for renal tumors between January 2011 and June 2016 at our institution...

Aims: Cell therapy trials using cardiac-resident progenitor cells (CPCs) and bone marrow-derived mesenchymal stem/progenitor cells (BMCs) in patients after myocardial infarction have provided encouraging results. Exosomes, nanosized extracellular vesicles of endosomal origin, figure prominently in the bioactivities of these cells. However, a head-to-head comparison of exosomes from the two cell types has not been performed yet. Methods and Results: CPCs and BMCs were derived from cardiac atrial appendage specimens and sternal bone marrow, respectively, from patients (n=20; age, 69...

OBJECTIVE: Data on renal hemodynamics, function, and oxygenation in early clinical septic shock are lacking. We therefore measured renal blood flow, glomerular filtration rate, renal oxygen consumption, and oxygenation in patients with early septic shock. DESIGN: Prospective comparative study. SETTING: General and cardiothoracic ICUs. PATIENTS: Patients with norepinephrine-dependent early septic shock (n = 8) were studied within 24 hours after arrival in the ICU and compared with postcardiac surgery patients without acute kidney injury (comparator group, n = 58)...

Clear lens extraction can be considered a therapeutic option in angle closure glaucoma (ACG). Even if it does not represent the first choice of treatment, it can be taken into consideration when the topical treatment does not control the intraocular pressure (IOP) and iridotomy does not have a positive effect on the angle closure, especially in appositional angle closure when biometry or ultrabiomicroscopy (UBM) show lens involvement. In angle closure glaucoma, clear lens extraction represents an etiological treatment that takes into account the role of the lens in the pathogenesis of the disease...

BACKGROUND: We previously reported that children undergoing cardiac surgery are at high risk for long-term chronic kidney disease (CKD) and hypertension, although postoperative acute kidney injury (AKI) is not a risk factor for worse long-term kidney outcomes. We report here our evaluation of renal injury biomarkers 5 years after cardiac surgery to determine whether they are associated with postoperative AKI or long-term CKD and hypertension. METHODS: Children aged 1 month to 18 years old undergoing cardiopulmonary bypass were recruited to this prospective cohort study...

Cancer patients are living longer. The sequelae of cancer treatment and the role of comorbid conditions present before the diagnosis, such as CKD, have been increasingly recognized. The interface between CKD and cancer is multifaceted. CKD is frequently observed in patients with cancer, and cancer treatment contributes to CKD development and progression. In addition, CKD has been recognized as an important risk factor for cancer development and reduced specific cancer survival. In this context, an accurate evaluation of the glomerular filtration rate (GFR) during oncologic treatment is pivotal and is used to define surgery strategies, program prophylactic management of contrasted examinations, make decisions on cisplatin eligibility, and adjust drug prescriptions, particularly chemotherapy agents...

OBJECTIVES: Robotic-assisted partial nephrectomy (RAPN) is preferred to radical nephrectomy because it guarantees superior functional outcomes in patients with small renal masses (RMs). Only a few studies so far have evaluated the feasibility of RAPN for the treatment of RM ≥4 cm. The aim of this study is to evaluate the safety and feasibility of RAPN based on a comparison of trifecta and pentafecta rates for RMs ≥4 cm. MATERIAL AND METHODS: We retrospectively analyzed prospectively collected data from an institutional database of patients undergoing RAPN from September 2013 to November 2016...

When discussing new trends in pediatric surgery, the tendency is to focus on novel surgical technology and techniques. However, it is equally important to examine how the practicing surgeon stays abreast in an ever-changing field. This article serves as a brief guide to the future of surgical education for the attending surgeon. Broadly, advances in surgical education consist of new methods of filtration and delivery of knowledge.

Lithium-induced nephrogenic diabetes insipidus (Li-NDI) is a rare and difficult-to-treat condition. A study in mice and two recent papers describe the use of acetazolamide in Li-NDI in 7 patients (a case report and a 6 patient series). We describe the case of a 63-year-old woman with bipolar disorder treated with lithium and no previous history of diabetes insipidus. She was hospitalized due to a bowel obstruction and developed severe dehydration after surgery when she was water deprived. After desmopressin administration and unsuccessful thiazide and amiloride treatment, acetazolamide was administrated to control polyuria and hydroelectrolytic disorders without significant side effects...

Introduction: Acute kidney injury (AKI) occurs frequently after abdominal aortic surgery and there is currently no effective marker able to detect early onset. The aim of this study is to evaluate the ability of neutrophil gelatinase-associated lipocalin (NGAL) to early identify the development of acute renal damage in patients undergoing endovascular aneurysm repair (EVAR) or open aortic repair (OAR). Materials and methods: Serial samples of blood and urine were obtained from 25 patients undergoing both EVAR and OAR...

BACKGROUND: This study was designed to investigate the effects of leukocyte filtration of autologous salvaged blood on lung function, lung inflammatory reaction, and oxidative stress reaction in elderly patients undergoing lumbar spinal surgery. MATERIALS AND METHODS: Sixty elderly patients undergoing lumbar spinal surgery were randomly divided into 2 groups: Leukocyte Filter group and Control group. Serum levels of inflammatory markers including white blood cell and polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, superoxide dismutase, interleukin (IL)-6, IL-8, tumor necrosis factor-α, and respiratory function markers including dynamic respiratory system compliance, oxygenation index, and respiratory index were measured immediately before induction of anesthesia (T0), immediately before blood transfusion (T1), and 1 (T2), 6 (T3), and 12 hours (T4) after end of blood transfusion...

Purpose: Glaucoma is a progressive optic neuropathy and a leading cause of blindness. Neural losses from glaucoma are irreversible, and so the aim of glaucoma treatment is to slow progression and minimize the risk of further damage. Visual loss post filtration surgery in patients with advanced glaucomatous optic nerve damage is a rare but dreaded complication. Functional improvement is not expected. We report the case of a patient who experienced a significant loss of vision following glaucoma surgery that was followed by late visual recovery...

AIM: To describe the pathological characteristics of the peritumoral non-neoplastic renal parenchyma (NNRP) and to investigate their impact on long-term renal function after partial nephrectomy. MATERIALS AND METHODS: In our institutional robotic partial nephrectomy database, we identified 394 cases with pathological assessment of the NNRP and long-term postoperative renal functional follow-up. The NNRP was classified as normal (healthy renal parenchyma) or abnormal, based on the presence of arteriosclerosis, glomerulosclerosis, interstitial fibrosis, interstitial inflammation, and/or tubulopapillary hyperplasia...

Severely obese patients undergoing bariatric surgery (BS) are at increased risk for venous thromboembolism (VTE). How standard low molecular weight heparin (LMWH) regimen should be adapted to provide both sufficient efficacy and safety in this setting is unclear. We aimed to compare the influence of four body size descriptors (BSD) on peak anti-Xa levels in BS obese patients receiving LMWH fixed doses to identify which one had the greatest impact. One hundred and thirteen BS obese patients [median body mass index (BMI), 43...
