US scan
DMSA
MCUG (micturating cystourethrogram)
64
What is vesicoureteric reflux?
A developmental anomaly of the vesicoureteric junctions. The ureters enter directly into the bladder rather than at an angle → urine can reflux back into ureter.
Severe disease can lead to backflow of urine into renal pelvis → scarring risk if UTIs occur.
65
What is an MCUG?
**Micturating cystogram**
to identify any vesicoureteric reflux (VUR), bladder abnormalities and posterior urethral valves within a few weeks after treatment of UTI.
The technique consists of catheterizing the child in order to fill the bladder with a radio-contrast agent then taking x-rays as the infant voids urine..
66

* Consider in children older than 6 months if dilatation on ultrasound, poor urine flow, non-E coli infection or family history VUR
67
What is a DMSA and when would you do it?
DMSA in **4-6 months** (after UTI). This is a **radionucleotide** scan used to assess **renal function** and identify any **scarring** of the kidneys due to the UTI. Healthy renal tissue takes up the isotope. Unhealthy or scarred tissue doesn’t take up the isotope and appears as a filing defect on DMSA scan.
**DMSA may be inaccurate if performed shortly after an infection.**
Indications:
All children with recurrent UTI
Children under 3 years with atypical UTI
68
You are asked to see a **boy** on the postnatal ward aged 1 day. The antenatal scan showed **bilateral** dilated kidneys. The child appears well and examination is normal. Nappies are wet.
What should you do?
Arrange ultrasound of kidneys within 24 hours
Need to exclude posterior urethral valves – this is a very serious condition which if untreated can cause renal failure due to obstruction.
If was just one side then outpatients is ok
69
What extra questions are important in fever or diarrhoea histories?
**Contact -** With other ill people - home or nursery, or with animals e.g. petting zoo
**Travel** - at risk areas, vaccination, contact with mosqitos, anyone ill on the plane?
70
When would you send a sample of stool for microscopy and culture?
NICE recommend sending stool for microbiology if you :
* suspect septicaemia,
* there is blood or mucus in the stool or
* the child is immunocompromised,
and to consider sending stool if
* there is a history of travel,
* the diarrhoea has persisted more than 7 days,
* or you are uncertain about the diagnosis of gastroenteritis.
