Q

Ix for enuresis

A

urinalysis not recommended unless recent onst or daytime symptoms

urine MC+S - look for any signs of UTI

renal tract USS - to see pre- and post-micturition residual volume

21
Q

management of primary enuresis

A

with/without daytime symptoms
- intervention not usually advised until age 7 - connection of the brain is still developing

  • avoid caffeine drink before bed, restricted fluid intake before bed
  • good bedtime hygiene
  • star chart - do not offer star for not wetting bed because children can not control it
  • enuresis alarm
  • desmopressin for short term purpose - sleepover
  • oxybutynin
22
Q

when will you refer an enuresis case

A

severe daytime symptoms - because potential developmental delay

secondary enuresis

suspected neuro probs

23
Q

what is the management of secondary enuresis

A

exclude UTI, constipation, emotional/stress related

refer to specialist

24
Q

definition of UTI

A

presence of symptoms - dysuria, frequency and loin pain

+

detection of a significant culture of organisms
(any detected in suprapubic aspirate or > 10(5) organism in MSU, clean catch urine or bag urine

25
Q

what is lower UTI

A

cystitis

26
Q

what is upper UTI

A

pyelonephritis

27
Q

what can pyelonephritis cause

A

scar if the kidney –> HTN

28
Q

epidemiology of UTI

A

3-7% of girl
1-2% of girls
both before 11 yrs old

50% have congenital abnor of the renal tract

29
Q

what are the pathogens that cause UTI in children

A

E.COli - 85%
Kliebsella
proteus
pseudomas

30
Q

what are the causes/RF for UTI

A

bowel flora entering the urinary tract

incomplete bladder emptying

  • infrequent voiding
  • vulvitis
  • incomplete micturition
  • constipation
  • neurogenic bladder
  • vesicoureter reflux - developmental anomaly
31
Q

clinical features of UTI

A
dysuria 
frequency 
loin pain 
fever +/- rigor
haematuria 
offensive/cloudy urine
febrile convulsion 
enuresis
32
Q

what are the clinical features of UTI in infancy

A

same as symptoms of older children

feeding difficulty
FTT
febrile convulsion
prolonged jaundice

33
Q

what can be a serious cause of UTI that is worth investigation of a social problem

A

sexual abuse

34
Q

what should you do as an examination when a child has UTI

A

plot height and weight on a growth chart
abdo mass
other mass
leg reflex - neurogenic bladder
spin and genitalia examination for any congenital abnor

35
Q

when would you investigation a UTI

A

1+ episode < 6 m - congenital abnor

2+ episodes > 6 m - congenital abnor + sexual abuse

36
Q

when will you not investigate a UTI

A

when a single episode > 6 m

37
Q

what investigations would you do for UTI

A

urinalysis

urine MC+S - MSU, clean catch, bag urine or urine aspirate

USS KUB - abnor structure, always do in acute phase or < 6 m

DMSA scan - to see if there are any scarring in the kidney

MCUG - to see if vesicoureteric reflux present

38
Q

treatment for UTI

A

hygiene, regular voiding, prevent constipation

< 3 m - IV ceftriaxone

> 3 m - oral trimethoprim

39
Q

what Abx should you avoid when treating UTI

A

tetracycline - stain teeth

40
Q

How can haematuria present

A

macroscopic haematuria - causes alarm to child and parents

incidental finding on screening

41
Q

what are some of the kidney cases of haematuria

A

kidney
- acute glomerulonephritis (preceded by Strep infection)
- henoch scholenin purpura - to large so cause kidney damage
- SLE - too large so cause kidney damage
- trauma
- bleeding disorder
- alport syndrome - thin membrane so easier to bleed
- tumour - Wilm’s tumour
exercise induce
drugs
polycystic kidney

42
Q

blood in urine 
abdo pain 
rashes 
abdo mass 
renal colic 
pain
46
Q

what examination would you do for haematuria

A

BP - for all patient with haematuria - HTn can cause kidney damage

skin rashes - HSP

joint pain

oedema - acute to acute glomerulonephritis - periorbital and ankle

renal mass

47
Q

Ix for haematuria

A

urine

  • dip - UTI
  • microscopy - to detect red cell cast, proteinura suggestign to glmoerular dmage
  • MC+S - UTI

Blood

  • FBC/CLotting - coagulopathy
  • U&E/cretinine/albumin - kindey function

USS KUB - detect any congenital abnor

48
Q

treatment for haematuria

A

treat any obvious causes (UTI)

if complex diagnosis eg proteinuria, reduced renal function) –> refer specialist

if not resovle in 6 m - refer specilaist
