BACKGROUND: 3D printing has been used in different medical contexts, although it is underutilised in paediatrics. We present the first use of 3D printing in the management of three paediatric patients with complex renovascular disease. METHODS: Patient-specific 3D models were produced from conventional 2D imaging and manufactured using 3D polyjet printing technology. All three patients had different underlying pathologies, but all underwent multiple endovascular interventions (renal artery balloon angioplasty) prior to 3D printing and subsequent vascular surgery...

BACKGROUND AND OBJECTIVES: Atherosclerotic renal artery stenosis may cause hypertension, chronic kidney disease and heart failure, but large randomized control trials to date have shown no major additional benefit of renal revascularization over optimal medical management. However, these trials did not consider outcomes specifically in relation to clinical presentations. Given that atherosclerotic renal artery stenosis is a heterogenous condition, measures of success likely differ according to the clinical presentation...

PURPOSE: Some children with hypertension (HTN) have unilateral poorly functional kidney (PFK). This provides an opportunity for the clinician to cure the HTN by removal of the PFK, thereby avoiding the problems of long-term medication. However, there is sparse data in children regarding the effect of PFK nephrectomy on curing HTN. In this review, we analysed the etiology of PFK causing HTN and the effectiveness of nephrectomy in curing HTN in children. METHODS: We searched the databases to identify papers between January 2000 to December 2020 pertaining to children with PFK and HTN who underwent nephrectomy...

INTRODUCTION: Chronic kidney disease affects a large part of the population with hypertension, diabetes mellitus as well as those over 50 years of age. Research reported that male sex and other comorbidities such as obesity and anemia are more frequent in Chronic kidney disease, as well as uncontrolled diabetes mellitus or hypertension. OBJECTIVE: To determine the risk factors associated with the development of chronic kidney disease in adults with arterial hypertension...

INTRODUCTION: AKI is a frequent complication in sepsis patients and is estimated to occur in almost half of patients with severe sepsis. However, there is currently no effective therapy for AKI in sepsis. Therefore, the therapeutic approach is focused on prevention. Based on this, there is an opportunity to examine a panel of biomarker models for predicting AKI. MATERIAL AND METHODS: This prospective cohort study analysed the differences in Cystatin C, Beta-2 Microglobulin, and NGAL levels in sepsis patients with AKI and sepsis patients without AKI...

Background: Nephrectomy with autotransplantation (NAT) has been performed as an alternative treatment for complex renovascular lesions, intricate ureteral strictures and nephron-sparing surgery in complex renal tumors. Methods : A retrospective observational study was conducted including patients who underwent a NAT from January 2010 to September 2023. Data collected included surgery indications, surgical technique, complications according to Clavien-Dindo classification and mean hospital stay. Descriptive and inferential statistical analysis was performed using IBM® SPSS® Statistics version 28...

Advances in the treatment of kidney failure with chronic dialysis have stagnated over the past three decades, with over 50% of patients still managed by conventional in-hospital haemodialysis. In parallel, the demands of chronic dialysis medical care have changed and evolved due to a growing population that has higher frailty and multimorbidity. Thus, the gap between the needs of kidney failure patients and the healthcare capability to provide effective overall management has widened. To address this problem, healthcare policy has increasingly aligned towards a human-centred approach...

Fibromuscular dysplasia is the most common cause of renovascular hypertension in young adults under 40 years old. It is potentially amenable to renal artery angioplasty, which frequently normalizes blood pressure. However, limited options exist if angioplasty is not technically possible, or restenosis occurs. Here, we describe 2 patients who presented with hypertension secondary to renal artery stenosis. In the first case, a young adult with hypertension secondary to renal artery stenosis (fibromuscular dysplasia), developed restenosis 11 weeks after an initially successful renal artery angioplasty...

PURPOSE: To assess the feasibility and efficacy of percutaneous transluminal renal angioplasty (PTRA) for pediatric renovascular hypertension (RVH) secondary to total renal artery occlusion (RAO). METHODS: From 2011 to 2021, 13 pediatric patients with RVH confirmed with 14 occluded renal artery lesions were reviewed. The mean age was11.2 years (range 4 to 16). Nine lesions involved main artery occlusion, while five lesions featured branch occlusion. Blood Pressure Ratio (BPR) was defined as the ratio of the actual BP value to the 95th percentile value adjusted for age, gender, and height...

Glomeruli can be damaged in several conditions after kidney transplantation, with a potential impact on the graft function and survival. Primary glomerulonephritis, a group of glomerular immunological damage that results in variable histological patterns and clinical phenotypes, can occur in kidney transplant recipients as a recurrent or de novo condition. Specific immunologic conditions associated with kidney transplantation, such as acute rejection episodes, can act as an additional trigger after transplantation, impacting the incidence of these glomerulopathies...

Hypertension is a leading cause of cerebral small vessel disease (CSVD) and vascular dementia in elderly individuals. We aimed to assess cerebral perfusion and dynamic changes in brain structure in stroke-prone renovascular hypertensive rats (RHRSPs) with different durations of hypertension and to investigate whether they have pathophysiological features similar to those of humans with CSVD. The RHRSP model was established using the two-kidney, two-clip (2k2c) method, and the Morris water maze (MWM) test, MRI, immunohistochemistry, and biochemical analysis were performed at multiple time points for up to six months following the 2k2c operation...

The U.S. is grappling with an opioid epidemic, with millions of adults on long-term opioid therapy (LTOT). Although patients often report pain relief and improved daily function with opioids, research shows no significant differences in short-term outcomes between opioid and non-opioid users, as well as no long-term opioid benefits. This scoping review aims to identify lesser-known side effects of long-term opioid use and increase awareness of them, allowing healthcare providers and patients to better assess the risks and benefits of opioid use...

BACKGROUND: Data on 25 [OH] vitamin D and intact parathyroid hormone [iPTH] in hemodialysis patients are very limited in sub-Saharan African countries. The present study aimed to assess the magnitude of hypovitaminosis D, and to evaluate the achievement of iPTH KDIGO 2017 targets among chronic hemodialysis patients followed in Kinshasa. METHODS: We conducted a multicenter cross-sectional study in 6 hospitals in Kinshasa. All patients followed on hemodialysis for more than 3 months were included...

Coral reef atherosclerosis of the paravisceral aorta is a rare disease whose description is confined to before contemporary vascular surgical techniques. This study aims to describe the characteristics and outcomes of patients with coral reef aorta treated with trapdoor endarterectomy at a single high-volume quaternary referral center since 2010. From 2010 to 2022, 14 patients with coral reef aorta were treated with trapdoor endarterectomy. The patient data were obtained via a retrospective medical record review...

Systemic hypertension is a strong risk factor for cardiovascular, neurovascular, and renovascular diseases. Central artery stiffness is both an initiator and indicator of hypertension, thus revealing a critical relationship between the wall mechanics and hemodynamics. Mice have emerged as a critical animal model for studying effects of hypertension and much has been learned. Regardless of the specific mouse model, data on changes in cardiac function and hemodynamics are necessarily measured under anesthesia...

The cardiovascular and renovascular complications of metabolic deterioration are associated with localized adipose tissue dysfunction. We have previously demonstrated that metabolic impairment delineated the heightened vulnerability of both the perivascular (PVAT) and perirenal adipose tissue (PRAT) depots to hypoxia and inflammation, predisposing to cardioautonomic, vascular and renal deterioration. Interventions either addressing underlying metabolic disturbances or halting adipose tissue dysfunction rescued the observed pathological and functional manifestations...

BACKGROUND: Patients with end stage renal disease (ESRD) are at a higher risk of developing tuberculosis (TB) due to the immunosuppressed state along with concomitant comorbidities and socioeconomic and demographic factors. Data on the prevalence of tuberculosis in ESRD are scarce despite the high burden of the disease in developing nations. METHODS: A multicenter, cross-sectional study was conducted at eight dialysis centers in Addis Ababa on the prevalence of TB among CKD patients on maintenance hemodialysis from August 2022 to October 2022 G...

BACKGROUND: End-stage kidney disease (ESKD) is associated with a tremendous financial burden. Data in Indonesia shows an increasing number of patients with ESKD taking hemodialysis as a routine procedure every year. Establishment and maintenance of vascular access are important in the management of ESKD. Vascular complications that often arise due to hemodialysis are common and one of the main reasons for hospitalization. Cannulation complications ranged from minor hematomas to acute bleeding from pseudoaneurysms that required emergency surgical procedures...

In June 2023, the European Society of Hypertension (ESH) presented and published the new 2023 ESH Guidelines for the Management of Arterial Hypertension, a document that was endorsed by the European Renal Association (ERA). Following the evolution of evidence in recent years, several novel recommendations relevant to the management of hypertension in patients with chronic kidney disease (CKD) appeared in these Guidelines. These include recommendations for target office BP < 130/80 mmHg in most and against target office BP < 120/70 mmHg in all patients with CKD; recommendations for use of spironolactone or chlortalidone for patients with resistant hypertension with eGFR higher or lower than 30 ml/min/1...
