Diagnosis & Prognosis

The diagnosis of acute uncomplicated symptomatic cystitis (AUC) is based on signs, symptoms and anamnestic data collection. RECAP

1 in 2 women of all ages experience at least one episode of cystitis during their lifetime.


Urine dipstick testing is able to increase diagnostic accuracy, but is not essential and should only be performed in the following situations:

  • Suspected acute pyelonephritis
  • Symptoms that do not resolve or recur within 4 weeks after the completion of treatment
  • Women who present with atypical symptoms
  • Pregnant women


The ACSS is a validated questionnaire which has recently been developed to:

  • Accurately assess the severity of symptoms and their impact on Quality of life
  • Help differentiate between other urogenital disorders
  • Monitor treatment efficacy

It is designed to promote (self) diagnosis and to help patients seek for medical advice.


ACSS is linguistically and clinically validated for a number of countries.
Please refer to the ACSS website for more details.

Complicated Urinary Tract Infections

Complicated UTIs are believed to result in an infection that will be more difficult to eradicate than an uncomplicated infection.

Complicated UTIs are related to:

Host’s factors

Host factors picto

Host’s factors (e.g. underlying diabetes or immunosuppression)

Specific anatomical

Pyelonephritis and urosepsis logo

Abnormalities of the urinary tract or functional abnormalities of the urinary tract (e.g. obstruction, incomplete voiding due to detrusor muscle dysfunction)

Symptoms

Cystitis

Cystitis is the most common type of UTI, caused by a bacterial infection of the bladder.

Acute uncomplicated symptomatic cystitis (AUC) will often clinically present with:

Cystitis logo
  • Acute dysuria (painful or difficult urination)
  • Increased urinary frequency and urgency
  • Suprapubic tenderness without fever

Pyelonephritis

Pyelonephritis can present with the following symptoms:

Pyelonephritis symptoms logo
  • Fever (>38°C)

  • Chills

  • Flank pain &/or costovertebral angle tenderness

  • Nausea &/or vomiting

Pregnant women with acute pyelonephritis need special attention, as this kind of infection may not only cause anaemia, renal and respiratory insufficiency for the mother, but can also cause frequent preterm labour and birth.

Risk factors – From cystitis to recurrences

Recurrent cystitis is defined as episodes of lower UTI infections occurring with a frequency of at least 3 episodes per year or at least 2 in 6 months.

Premenopausal woman…

Sexual activity
Use of spermicides
Life time history of UTIs
History of UTI during childhood
A mother with a history of UTI

Postmenopausal women…

Postmenopausal woman logo

Oestrogen deficiency
Atrophic vaginitis
Increased post-void urine volume
Urinary or faecal incontinence

Predicting recurrence

Recurrent cystitis should be managed carefully to prevent new symptomatic episodes and complications.
LUTIRE is a nomogram that has been developed to help predict the recurrence risk at 12 months by analysing:

Genders logo
  • Number of sexual partners
  • Bowel function
  • Type of pathogens isolated
Hormonal logo
  • Hormonal status
  • Number of previous UTI recurrences
  • Previous treatment of ABU

UTI complications

Cystitis bacteria logo
  • Recurrent cystitis could lead to complications, as well as being a risk factor for the development of upper UTIs, although the risk is very low
  • Even if an infection by a resistant bacteria is more difficult to treat, this is not considered a risk for complicated UTI

Complications

Pyelonephritis and urosepsis

Pyelonephritis and urosepsis logo

Misdiagnosis of uncomplicated cystitis or progression to complicated UTI can lead to acute kidney injury, pyelonephritis and sepsis.

Change in microbiota

Microbiota logo

The antibiotics used to treat UTIs have a broad spectrum of action and are effective not only against the uropathogen, but also on healthy microbiota. This results in a number of collateral damages, which lead to more difficult to treat and / or recurrent cystitis / UTIs: RECAP

  • A decrease in the species richness and diversity of the microbiota
  • Selection and spread of antibiotic-resistant microorganisms
  • Transfer of resistance amongst commensal bacteria and potential uropathogens

Stress urinary incontinence

Stress urinary icon

rUTIs are associated with stress urinary incontinence (the involuntary leakage of urine from the bladder accompanying physical activity, which places increased pressure on the abdomen).

  • Acute UTIs are associated with acute urinary incontinence (both stress and urge incontinence) in up to a quarter of infected women RECAP

Psychological impact

Psychological issues icon

Psychological issues may arise due to stress and impairment of daily life.

  • Women with recurrent UTIs showed a 10-fold increase in psychiatric symptoms compared to the normal population
