Explain the difference between an uncomplicated UTI and a complicated UTI

Uncomplicated UTI is usually considered to be cystitis or pyelonephritis that occurs in premenopausal adult women with no structural or functional abnormality of the urinary tract and who are not pregnant and have no significant comorbidity that could lead to more serious outcomes.




A UTI is considered complicated if the patient is a child, is pregnant, or has any of the following:



  • A structural or functional urinary tract abnormality
  • obstruction of urine flow
  • A comorbidity that increases risk of acquiring infection or resistance to treatment, such as poorly controlled diabetes, chronic kidney disease, or immunocompromise.
  • Recent instrumentation or surgery of the urinary tract
Uncomplicated UTI can involve either sex at any age. It is usually considered to be pyelonephritis or cystitis

Define pyelonephritis and Cystitis

Pyelonephritis pyelo' (pelvis), 'nephros' (kidney), and '-itis' (inflammation) - Severe infectious inflammatory disease of the renal parenchyma, calices, and pelvis that can be acute, recurrent, or chronic. Acute infections may be caused by enteric bacteria (e.g., Escherichia coli) that ascend from the lower urinary tract or that spread haematogenously to the kidney.




Cystitis is infection of the bladder. It is common in women, in whom cases of uncomplicated cystitis are usually preceded by sexual intercourse (honeymoon cystitis).
