UTIs are a bread-and-butter topic for the AKT, but the guidelines (NICE/PHE) are quite specific about when to test and what to prescribe. Let's break this down into the three areas you mentioned.

1. Diagnosis: When to Dipstick?

The most important thing to remember for the exam is that diagnosis is primarily clinical for most women.

• Simple UTI (Non-pregnant women <65): If they have 3 or more key symptoms (dysuria, new nocturia, cloudy urine, urgency, or frequency), you can diagnose and treat without a dipstick or culture.
• The "Dipstick Rule": Only dipstick if they have <3 symptoms. If it's positive for nitrites or leukocytes, treat.
• When to Culture (MSU):
  • Pregnancy (always screen for asymptomatic bacteriuria at booking!).
  • Men (UTIs in men are always considered "complicated").
  • Children.
  • Suspected Pyelonephritis (fever, loin pain).
  • Recurrent UTI or failed initial treatment.

2. Antibiotic Choice (UK Guidelines)

For an uncomplicated lower UTI, the first-line options are usually a 3-day course for women and a 7-day course for men/pregnant women.

Note: Avoid Nitrofurantoin if the eGFR is <45 as it won't reach effective concentrations in the bladder.

3. Recurrent UTI Management

Recurrent UTI is defined as ≥2 episodes in 6 months or ≥3 episodes in 12 months.

• Lifestyle Advice: Increase fluid intake, "post-coital voiding" (peeing after sex), and avoiding spermicides.
• Non-Antibiotic Options: For post-menopausal women, vaginal oestrogen cream is a high-yield answer as it restores the vaginal flora. D-mannose is also now recommended as an option.
• Antibiotic Prophylaxis:
  • Post-coital: A single dose of Nitrofurantoin or Trimethoprim taken immediately after intercourse.
  • Continuous: A low-dose daily antibiotic (usually tried for 6 months).

I'll pull up some high-yield lessons and a flowchart to help you visualize the management pathway for recurrent cases.

Those lessons cover the core theory, but let's look at a clinical algorithm for managing recurrent UTIs in women, as this is a common AKT scenario.

That flowchart should help you keep the management steps clear. One final high-yield tip for the AKT: always check the eGFR before prescribing Nitrofurantoin. If it's below 45, it's generally avoided (though some guidelines say 30-44 is okay for short courses if there's no other option).

Would you like to try a few practice questions on this topic to see how it's tested, or should we look at UTIs in specific groups like pregnancy or children?
