USS DMSA MCUG
infants w/atypical or recurrent UTI should have USS DMSA within 4-6m of acute infection if: - <3y w/atypical/recurrent - >3y w/recurrent MCUG if recurrent or if abnormal USS
Medical measures to prevent UTI
Aim: ensure washout of organisms that ascending and the presence of aggressive organisms in the stool perineum and under foreskin
High fluid intake to produce high urine output
Complete bladder emptying
Good hygiene
Lactobacillus acidophilus: probiotic
FU of children w/recurrent UTI, renal scarring or reflux
Urine dipsticked with any non-specific illness incase it is UTI, MC+S Low dose abx proph. possible Circumcision in boys? anti-VUR surgery Regular BP checking Urinalysis for proteinuria (CKD)
Summary of UTI in children
<3m refer immediately to paeds
>3m w/upper UTI: consider admission otherwise PO abx 7-10d
>3m w/lower UTI PO ABx 3d
Recurrent: ?prophylaxis
Enuresis
most children dry day and night by 5 (day only by 4)
Primary bedwetting (w/o daytime Sx):
- Children <5: reassure is normal, ensure easy access to toilet at night (potty next ti bed), encourage bladder and bowel emptying before bed, consider reward sysytem
Children >5: if <2/wk then watch and see, if long term treatment required:
1st line: enuresis alarm w/reward system
2nd:desmopressin (restrict fluid 1hr before to 8hr after)
Offer desmo for short term control eg school trip
If Mx for enuresis fails
Restart previously successful in combination w/desmo and alarm
TCA and anitmuscarinics can be considered in cases
Referral for enuresis
NOT responded to 2 courses of Mx, refer to 2ndry care, specialist clinic or paediatrician
Advice on enuresis
NOT anyone’s fault
Volume exceeds capacity but doesnt wake child
Reassure almost all will become dry as bladder grows and they learn sensation
Pass regularly, esp. before bed
Caffeine drinks avoided (before bed)
Healthy diet
Easy access to toilet
waterproof mattress
Neutral attitude as not to embarrass
Older children may prefer to change it themselves
Waking in the night does NOT promote long term dryness
Positive support
support: ERIC
Primary bedwetting w/daytime Sx
Refer to secondary care/enuresis clinic
Secondary bedwetting
occurs after previously been dry for 6m
Causes that can be manged in primary care: UTI, constipation
Specialist referral:
DM, recurrent UTI, psych, family problems, developmental delay, neurological/physical problems
Summary of enuresis
Look for causes: constipation/diabetes Fluid intake, toilet behaviour reward system 1st line <7y = alarm desmopressin 1L if >7 or short term control needed
Nephrotic syndrome
PO steroids (60mg/m^2 pred) After 4wks dose reduced If no resp. after 4wks or have atypia may have more complex Dx and need biopsy NB. renal histology of steroid sens. NS is usually normal on light micros. but fusion of podocyes on EM - minimal change Dx
