1. Evaluation of the prevalence and factors associated with acute kidney injury in a pediatric intensive care unit
Abstract Objective To assess the prevalence of acute kidney injury in pediatric intensive care unit according to diagnostic criteria - pediatric risk, injury, failure, loss, end-stage renal disease, Acute Kidney Injury Network and Acute Kidney Injury Work Group, or Kidney Disease: Improving Global Outcomes -, and determining factors associated with acute ki

2. EFFECT OF CHRONIC RENAL DYSFUNCTION ON THE PERMEABILITY OF THE COLON TO WATER AND ELECTROLYTES: EXPERIMENTAL STUDY IN RATS
RESUMO Racional: A insuficiência renal é doença que afeta diversos órgãos por provocar hipervolemia e quadro urêmico ao organismo. A doença atinge mais de 500 milhões de pessoas em todo o mundo, e poucos estudos trazem sua influência sobre o trato gastrointestinal. Objetivo: Avaliar a influência da hipervolemia induzida pela nefrectomia 5/6 sobr

3. Indicações e resultados para o uso expandido da oclusão ressuscitativa por balão endovascular da aorta - REBOA.
RESUMO A oclusão ressuscitativa por balão endovascular da aorta (REBOA) é utilizada para controlar hemorragias não compressíveis do tronco como uma opção menos invasiva e com menos distúrbios fisiológicos quando comparado à toracotomia de emergência com clampeamento da aorta. Isso permite a melhora dos parâmetros hemodinâmicos até que a cirurgi

4. Impact of Transcatheter Aortic Valve Implantation on Kidney Function
Resumo Fundamento: Pacientes com doença valvar aórtica frequentemente apresentam doença renal crônica (DRC). Diminuição da perfusão renal como consequência da redução do débito cardíaco pode contribuir para a disfunção renal neste cenário. Objetivo: Dado o potencial de reversibilidade da hipoperfusão renal após o reparo valvar, este estudo

5. Máquina de perfusão versus armazenamento estático na preservação renal de doadores com morte encefálica: revisão sistemática e metanálise.
RESUMO Com a utilização crescente da máquina de perfusão no transplante renal, tem sido constatado que a isquemia dinâmica correlaciona-se à melhora da preservação orgânica. Nesse contexto, realizamos uma revisão sistemática que procurou avaliar a eficácia do uso de máquina de perfusão portátil (LifePort Kidney Transporter Machine®), utilizad

6. Which is best method for instillation of topical therapy to the upper urinary tract? An in vivo porcine study to evaluate three delivery methods
ABSTRACT Purpose: To compare the staining intensity of the upper urinary tract (UUT) urothelium among three UUT delivery methods in an in vivo porcine model. Materials and methods: A fluorescent dye solution (indigo carmine) was delivered to the UUT via three different methods: antegrade perfusion, vesico-ureteral reflux via in-dwelling ureteric stent and

7. Perconditioning combined with postconditioning on kidney ischemia and reperfusion
Abstract Purpose: To evaluate if combination of perconditioning and postconditioning provides improved renal protection compared to perconditioning alone in a model of renal reperfusion injury. Methods: Thirty rats were assigned into 6 groups: normality; sham; ischemia and reperfusion; postconditioning; perconditioning; perconditioning + postconditioning.

8. The renoprotective effect of oral Tadalafil pretreatment on ischemia/reperfusion injury in rats
Abstract Purpose: To evaluate the effect of tadalafil in renal ischemia/reperfusion (I/R) injury in rats Methods: Group I/R saline rats (n=6) were subjected to 45 minutes of left renal ischemia and treated with saline; the I/R tadalafil rats (n=6) received oral 10mg/kg tadalafil microemulsion one hour before ischemia. In both groups, 8 hours after ischem

9. Antegrade pressure measurement of urinary tract in children with persistent hydronephrosis
INTRODUCTION: Dilation of urinary tract occurs without the presence of obstruction. Diagnostic methods that depend on renal function may elicit mistaken diagnosis. Whitaker (1973) proposed the evaluation of urinary tract pressure submitted to constant flow. Other investigators proposed perfusion of renal pelvis under controlled pressure, making the method mo

10. Renal- and calcium-dependent vascular effects of Polybia paulista wasp venom
In the present study, the effects of Polybia paulista venom (PPV) on renal and vascular tissues were investigated. Isolated kidneys perfused with PPV (1 and 3 μg/mL) had increased perfusion pressure, renal vascular resistance, urinary flow, and glomerular filtration rate; and reduced sodium tubular transport. Histological evaluation demonstrated deposits of

11. Renal and vascular effects of Crotalus durissus cumanensis venom and its crotoxin fraction
In this study, we evaluated the actions of Crotalus durissus cumanensis venom (CDCmV), and its crotoxin (Crtx) fraction, on renal and vascular functions in Wistar rats. In isolated perfused kidneys, CDCmV (10 µg/mL) significantly increased the perfusion pressure (PP) from 110.7 ± 2.4 to 125.3 ± 2.8 mmHg after 30 minutes. This effect was accompanied by an

12. Efeitos inibitÃrios da sertralina no sistema urinÃrio de ratos. / Inhibitory effects of sertraline on rat urinary system.
Sertraline, a drug belonging to the family of selective serotonin reuptake inhibitors, is used in antidepressant therapy, and has good tolerance with low incidence of side effects. Here we have characterized the pharmacological effects of sertraline on the pattern of voiding anesthetized rats, on the renal functional parameters of isolated rat kidney and on
