Objective 14: State the Signs and Symptoms of Cystitis, Urethritis and Pyelonephritis. Discuss Treatment of UTIs

Cystitis

Inflammation of the bladder that causes irritation and urinary symptoms.

Cystitis Manifestations

Frequency, urgency, dysuria, nocturia, and pelvic discomfort.

Urethritis

Inflammation of the urethra that commonly causes burning or pain during urination.

Lower UTI Systemic Manifestations

Possible fever, malaise, nausea, and leukocytosis.

Cloudy Urine

May occur with urinary infection due to bacteria and inflammatory cells.

Bacteriuria

Bacteria present in the urine.

Pyuria

Increased white blood cells in the urine.

Microscopic Hematuria

Small amounts of blood detected in urine through laboratory testing.

Pyelonephritis

Infection and inflammation involving the renal pelvis and kidney tissue.

Ascending Pyelonephritis

Infection that spreads from the urethra to the bladder and then through the ureters to the kidneys.

Purulent Exudate

Inflammatory material and pus that may accumulate in the renal pelvis and calyces during kidney infection.

Pyelonephritis Manifestations

Frequency, urgency, dysuria, flank or back pain, high fever, chills, and shaking.

Urinary Casts in Pyelonephritis

Casts that indicate inflammation or infection involving the renal tubules.

Chronic Pyelonephritis

Repeated or persistent kidney infection that can cause renal scarring and loss of nephron function.

UTI Antibiotic Treatment

Antibiotics directed at the bacteria responsible for the infection.

Completing Antibiotic Therapy

Finishing the entire prescribed course helps prevent surviving bacteria from multiplying again.

Treatment of Severe Pyelonephritis

May require more intensive treatment and monitoring because kidney involvement can cause permanent damage.

What are the common symptoms of cystitis?

Frequency, urgency, dysuria, nocturia, and pelvic discomfort.

Why does cystitis cause frequent urination?

Inflammation irritates the bladder and makes it feel full more often.

What is the main urinary symptom of urethritis?

Burning or pain during urination.

What systemic symptoms may occur with lower UTIs?

Fever, malaise, nausea, and leukocytosis.

What may cloudy or foul-smelling urine indicate?

Possible urinary tract infection and inflammation.

What is bacteriuria?

The presence of bacteria in the urine.

What is pyuria?

An increased number of white blood cells in the urine.

What is microscopic hematuria?

Blood in the urine that is detectable only through laboratory examination.

What is pyelonephritis?

Infection and inflammation involving the renal pelvis and kidney tissue.

How does pyelonephritis commonly develop?

Bacteria ascend from the urethra to the bladder and then through the ureters to the kidneys.

What is purulent exudate?

Inflammatory material and pus that may accumulate in the renal pelvis and calyces.

What symptoms distinguish pyelonephritis from a lower UTI?

Flank or back pain, high fever, chills, and shaking.

Why are urinary casts important in pyelonephritis?

They indicate that inflammation or infection involves the kidney tubules.

What can recurrent kidney infections cause?

Renal scarring, loss of nephron function, and potentially chronic renal failure.

How are bacterial UTIs generally treated?

With antibiotic therapy directed at the responsible bacteria.

Why must patients complete their prescribed antibiotic course?

Stopping early can allow surviving bacteria to multiply and cause the infection to return or progress.

Why may severe pyelonephritis require intensive treatment?

Kidney involvement can cause permanent scarring and impaired renal function.
