What are the general predisposing factors which make an individual more susceptible to UTI?

A

Immunosuppression

Steroids

Malnutrition

Diabetes

Female sex (short urethra)

Sexual intercourse and poor voiding habits

Congenital abnormalities e.g. duplex kidney

Stasis of urine e.g. due to poor bladder emptying

A

–Diarrhoea

–Excessive crying

–Fever

–Nausea and vomiting

–Not eating

7

Q

What are the clinical features of acute pyelonephritis?

A
  • Pyrexia
  • Poor localisation
  • Loin tenderness (renal angle)
  • Signs of dehydration
  • Turbid urine
9

MSSU

•Urinalysis In ward

–Blood,

–leucocytes,

–protein and

–nitrites

10
Q

What are the relevant investigations for children, men or when UTIs are frequent?

A

Ultrasound or IVU may be helpful

Isotope studies to rule our reflux and scarring

11
Q

What are the principles of management of UTI?

A

1 Identify the infecting organism & institute appropriate treatment

2 Identify predisposing factors and treat if possible

12
Q

What is the treatment of UTI?

Q

When is renal impairment likely to occur after a urinary tract infection?

A

If the urinary tract is functionally normal (on imaging) - repeated / persistent UTI’s seldom result in renal damage

If there is anotomical / neurological abnormalities / stones / diabetes - may cause infections and sometimes lead to renal impairment

14

A

Reflux and infection
