Preoperative assessment in chronic kidney disease

BACKGROUND: Partial nephrectomy (PN) is generally preferred for localized renal masses due to strong functional outcomes. Accurate prediction of new baseline glomerular filtration rate (NBGFR) after PN may facilitate preoperative counseling because NBGFR may affect long-term survival, particularly for patients with preoperative chronic kidney disease. Methods for predicting parenchymal volume preservation, and by extension NBGFR, have been proposed, including those based on contact surface area (CSA) or direct measurement of tissue likely to be excised/devascularized during PN...

OBJECTIVES: To investigate preoperative patient factors that may predict the occurrence of perioperative complications following robot-assisted radical cystectomy at a single center in Japan. METHODS: From 2013 to 2022, 103 patients underwent RARC at our institution. Complications within 90 days after surgery were assessed using the Clavien-Dindo classification. Preoperative characteristics and surgical outcomes were compared between cohorts with and without complications ≥grade 3...

Prostate cancer is a prevalent malignancy in male patients, having diverse clinical outcomes. The follow-up of patients diagnosed with prostate cancer involves the evaluation of renal function, because its impairment reduces patient survival rates and adds complexity to their treatment and clinical care. This study aimed to investigate the relationship between renal function parameters and distinctive molecular subtypes of prostate adenocarcinomas, defined by the immunoexpression of the SPINK1, ERG, HOXB13, and TFF3 markers...

BACKGROUND/PURPOSE: To investigate the safety of laparoscopic liver resections (LLRs) for high-risk patients (HRs) with preoperative comorbidities affecting the heart, lungs, kidneys, glucose tolerance, and central nervous system. METHODS: This retrospective study included 585 patients who had undergone total hepatectomies from 2006 to 2020. Among them, 239 patients underwent LLRs, and 349 underwent open liver resections (OLRs). The safety and validity of LLRs were analyzed by comparing outcomes and preoperative records between HRs and nonhigh-risk patients (nHRs)...

OBJECTIVE: This study aimed to construct and validat a clinical prediction model for Surgical site infection (SSI) risk 30 days after gastrointestinal surgery. MATERIALS AND METHODS: This multi-centre study involving 57 units conducted a 30-day postoperative follow-up of 17,353 patients who underwent gastrointestinal surgery at the unit from 1 March 2021 to 28 February 2022.

BACKGROUND: Chronic kidney disease is a prevalent condition in surgical patients. Possible associations with increased postoperative morbidity and mortality have not been clearly demonstrated in patients undergoing pancreatoduodenectomy. The aim of this study was to assess the risk of postoperative complications in patients with reduced kidney function undergoing pancreatoduodenectomy. METHODS: All patients undergoing pancreatoduodenectomy at Karolinska University Hospital between 2008 and 2019 were retrospectively included...

BACKGROUND: Pharmacogenomics is an emerging and affordable tool that may improve postoperative pain control. One challenge to successful pain control is the large interindividual variability among analgesics in their efficacy and adverse drug events. Whether preoperative pharmacogenomic testing is worthwhile for patients undergoing TKA is unclear. QUESTIONS/PURPOSES: (1) Are the results of preoperative pharmacogenetic testing associated with lower postoperative pain scores as measured by the Overall Benefit of Analgesic Score (OBAS)? (2) Do the results of preoperative pharmacogenomic testing lead to less total opioids given? (3) Do the results of preoperative pharmacogenomic testing lead to changes in opioid prescribing patterns? METHODS: Participants of this randomized trial were enrolled from September 2018 through December 2021 if they were aged 18 to 80 years and were undergoing primary TKA under general anesthesia...

OBJECTIVE: Fenestrated endovascular aneurysm repair (FEVAR) is a well-established treatment approach for juxtarenal and short neck infrarenal aortic aneurysms. Recommendations and clinical outcomes are lacking for offering FEVAR in patients with chronic kidney disease (CKD). We aimed to compare short and long-term outcomes for patients with none-to-mild versus moderate-to-severe CKD undergoing FEVAR. METHODS: We retrospectively reviewed consecutive patients undergoing standard FEVAR with Cook devices at a single institution...

Horseshoe kidney or ren arcuatus is the most common renal fusion anomaly, with an incidence of 1:500 in the normal population and a male predominance of 2:1. In >90% of cases, the fusion occurs along the inferior pole. It may vary in location, orientation, and arterial and venous anatomy. In 1522, Berengario da Carpi described this renal malformation for the first time in his masterpiece "Isagogae breves" (Introduction to Anatomy). He reported the results of a postmortem examination in the public autopsy room of the University of Bologna, describing "kidneys that are continuous as if they were a kidney, with two emulsifying veins, two emulsifying arteries, two ureteral outlets...

BACKGROUND AND AIMS: Though the role of fasting preoperative gastric ultrasound has been validated in different patient populations, namely, obese, pregnant and diabetics, it has not been explored in patients with chronic kidney disease (CKD). This prospective, observational study compared the fasting sonological assessment of gastric contents in patients with CKD versus those with normal renal function scheduled for elective surgery. METHODS: After ethical approval and trial registration were obtained, preoperative gastric ultrasound was done in 115 CKD patients and 115 with normal renal function...

CONTEXT: There is no high-level evidence regarding the risk factors of glomerular filtration rate (GFR) loss following radical cystectomy (RC) and survival outcomes of patients with chronic kidney disease (CKD) undergoing RC. OBJECTIVE: To identify the risk factors of CKD in patients treated with RC for bladder cancer and to assess overall and oncological survival of patients with CKD who underwent RC. EVIDENCE ACQUISITION: According to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement, two systematic reviews were performed for studies published before September 30, 2022, assessing (1) risk factors of renal function (RF) decline following RC and (2) overall and oncological outcomes of CKD patients treated with RC...

BACKGROUND: Older patients are vulnerable to developing new or worsening disability after surgery. Despite this, patient or surgical characteristics predisposing to postoperative disability are poorly defined. Our aim was to develop and validate a model, subsequently transformed to point-score form, to predict 6-month death or disability in older patients after surgery. METHODS: The authors built a prospective, single-center registry to develop and validate the prediction model...

PURPOSE: To describe the practice of robotic-assisted partial nephrectomy (RAPN) in France and prospectively assess the late complications and long-term outcomes. METHODS: Prospective, multicenter (n = 16), observational study including all patients diagnosed with a renal tumor who underwent RAPN. Preoperative, intraoperative, postoperative, and follow-up data were collected and stored in the French research network for kidney cancer database (UroCCR)...

BACKGROUND: Reliable vascular access (VA) is required for patients receiving chronic hemodialysis (HD) treatment. Vascular mapping using duplex doppler ultrasonography (DUS) can aid in planning VA construction. Greater handgrip strength (HGS) was found to be associated with more developed distal vessels both in chronic kidney disease (CKD) patients and healthy individuals, and patients with lower HGS had worse morphologic vessel characteristics and were, therefore, less likely to construct distal VA...

OBJECTIVE: To determine the results, safety and clinical outcomes of carotid interventions performed with Duplex ultrasound (DUS) as a single preoperative image for internal carotid artery (ICA) assessment, compared to computed tomography angiography (CTA) and magnetic resonance angiography (MRA). METHODS: Prospective, consecutive cohort study of two groups of patients submitted to carotid interventions, one group of patients with DUS as a sole exam (group DUS) compared to patients with DUS plus CTA or MRA for ICA stenosis diagnosis (group CTA/MRA) regarding clinical outcomes such as major stroke, minor stroke, transient ischemic attack and perioperative mortality...

Background. The aim of this study was to assess the incidence of two post-operative acute kidney injury (AKI) stages according to the Risk, Injury, Failure, Loss of function, End-stage (RIFLE) criteria in patients undergoing fenestrated endovascular aortic repair (FEVAR) for complex aortic aneurysms. Furthermore, we analyzed predictors of post-operative AKI and mid-term renal function deterioration and mortality. Methods. We included all patients who underwent elective FEVAR for abdominal and thoracoabdominal aortic aneurysms between January 2014 and September 2021, independently from their preoperative renal function...
