Objective Three: Discuss Manifestations of Urinary Disorders

Urinary frequency

Need to urinate more often than usual.

Urinary urgency

Sudden, persistent feeling that urination is necessary.

Dysuria

Burning, discomfort, or pain during or immediately after urination.

Nocturia

Repeated need to wake during the night to urinate.

Urinary incontinence

Involuntary or accidental leakage of urine.

Hematuria

Blood in urine; may be gross (visible) or microscopic (laboratory-detected).

Proteinuria

Excessive protein in urine; may indicate glomerular filtration-barrier damage.

Bacteriuria

Presence of bacteria in urine; commonly suggests UTI depending on clinical context.

Pyuria

Increased leukocytes (white blood cells) in urine; commonly indicates urinary inflammation or infection.

Urinary casts

Tube-shaped microscopic structures formed in renal tubules; suggest a kidney/nephron source of disease.

Erythrocyte casts

Urinary casts containing red blood cells; may occur with glomerular inflammation.

Leukocyte casts

Urinary casts containing white blood cells; can indicate kidney inflammation or infection.

How do frequency, urgency, and dysuria differ?

Frequency: urinating more often; urgency: sudden persistent need; dysuria: burning, discomfort, or pain with urination.

What are nocturia and incontinence?

Nocturia: waking repeatedly at night to urinate; incontinence: involuntary urine leakage.

What is the difference between gross and microscopic hematuria?

Gross blood is visible to the naked eye; microscopic blood is detectable only by laboratory examination.

What can proteinuria indicate?

Damage to the glomerular filtration barrier, which normally prevents most plasma proteins from entering urine.

What do bacteriuria and pyuria indicate?

Bacteriuria is bacteria in urine; pyuria is increased white blood cells in urine and commonly indicates inflammation or infection.

Why are urinary casts clinically important?

They form in renal tubules and suggest the disorder originates within the kidney rather than only the bladder or urethra.

What do erythrocyte and leukocyte casts suggest?

Erythrocyte casts may indicate glomerular inflammation; leukocyte casts may indicate kidney inflammation or infection.
