Introduction

--- Content provided by‌ FirstRanker.com ---

? Symptomatic presence of

micro organisms within

the urinary tract

--- Content provided by FirstRanker.com ---


i.e., kidney, ureters,

bladder and urethra.

--- Content provided by⁠ FirstRanker.com ---

? Associated with

inflammation of

urinary tract.

Anatomy

vThe upper urinary tract,

--- Content provided by⁠ FirstRanker.com ---

composed of the kidneys,

renal pelvis, and ureters.

v the lower urinary tract

--- Content provided by FirstRanker.com ---


that consists of the

urinary bladder and the

urethra.

v Upper urinary tract infections affect the ureters

(ureteritis) or the renal parenchyma (pyelonephritis).

v Lower urinary tract infections may affect the urethra

(urethritis), the bladder (cystitis), or the prostate in

males (prostatitis).

UTI - Terminology

--- Content provided by​ FirstRanker.com ---


v Significant bacteriuria: presence of at least 105

bacteria/ml of urine.

--- Content provided by‌ FirstRanker.com ---

v Asymptomatic bacteriuria : bacteriuria with No symptoms.

v Uncomplicated: UTI without underlying renal or

neurologic disease.

--- Content provided by⁠ FirstRanker.com ---


v Complicated: UTI with underlying structural, medical or

neurologic disease.

--- Content provided by‌ FirstRanker.com ---

v Recurrent : > 3 symptomatic UTIs within 12 months

following clinical therapy.

v Reinfection: recurrent UTI caused by a different pathogen

--- Content provided by⁠ FirstRanker.com ---


at any time
v Relapse: recurrent UTI caused by same species

causing original UTI within 2 wks after therapy.

--- Content provided by‌ FirstRanker.com ---


v Urethritis: infection of anterior urethral tract

v Cystitis: infection to urinary bladder

--- Content provided by‌ FirstRanker.com ---

v Acute pyelonephritis: infection of one/both kidneys;

sometimes lower tract also.

v Chronic pyelonephritis: particular type of pathology of

--- Content provided by​ FirstRanker.com ---


kidney; may/may not be due to infection.

vPyuria

--- Content provided by FirstRanker.com ---

? the presence of 10 WBC/cumm in a urine specimen,

? 1-5 white cel s per high-power field of uncentrifuged

urine,

--- Content provided by FirstRanker.com ---


? or a urinary dipstick test that is positive for leukocyte

esterase.

--- Content provided by‌ FirstRanker.com ---

vSterile pyuria

- the persistent finding of white cel s in the urine in the

absence of bacteria.
