Urine culture
USS if proteus
What is treatment for simple lower UTI in kids?
Trimethroprim
Co-trimoxazole
Cephalosporin
Tx for upper UTI?
Gentamicin
Co-amox
Cephalosporin
What is investigation for vesico-ureteric reflux?
MAG3 (tecnetium-99 filtered by kidneys then imaged)
DMSA (for scarring)
Micturating cystourethrogram
What is the grading of VUR?
Grade I: ureter only
Grade II: ureter, calyces, pelvis
Grade III: ureter dilatation
Grade IV: moderate dilatation/torsion/fornice obliteration
Grade V: gross dilatation or tortuous ureter
Treatment of VUR?
Voiding advice
Prophylactic trimethroprim
STING procedure
What is a STING procedure?
Injection of a polymer into the VU junction that reduced the diameter of the ureters and allows them to close properly under action of the bladder
What is typical vs atypical glomerulonephritis?
Typical = minimal change
Typical means it responds to normal steroid treatment
Atypical = focal segmental
Atypical means it is steroid resistance
What is a congenital glomerulonephritis?
NPHS1 - gene for nephrin
Leads to loss of podocytes
What causes nephrotic syndrome?
Loss of protein through the glomeruli leading to decrease in oncotic pressure, causing proteinuria and leading to oedema as water moves out of vascular system due to hydrostatic pressure
What is the triad of nephrotic syndrome?
Hypoalbuminaemia
Hyperlipidaemia
Proteinuria
What indicates nephrotic syndrome on dipstick?
Protein >250mg
What is gold standard investigation for nephrotic syndrome?
24hr urine collection
Tx typical nephrotic syndrome?
Prednisolone
Tx atypical nephrotic syndrome?
Ciclosporin
What must be checked before starting prednisolone in kids?
Varicella status
What % of nephrotic remit?
95%
What % of nephrotic relapse?
84%
