Study Notes
Urinary Tract Obstructions
- Urinary tract obstructions occur when urine flow is impeded.
- Causes can be anatomical or functional abnormalities.
- Severity depends on location, blockage degree, duration, and underlying cause.
- Upper urinary tract obstructions involve kidneys or ureters.
- Common causes: kidney stones, ureteral strictures, tumors, blood clots, congenital anomalies in children.
- Lower urinary tract obstructions involve bladder or urethra.
- Common causes: urethral strictures, prostate enlargement, pelvic organ prolapse in women, tumors, neurogenic bladder.
Pathophysiological Mechanisms
- Urine backs up behind the blockage, increasing pressure upstream.
- This dilation causes hydroureter (distended ureter) and hydronephrosis (distended renal pelvis and calyces).
- Increased pressure reduces glomerular filtration rate because of the reduced pressure.
- Urinary stasis leads to infection risk.
- Damage to renal nephrons may lead to chronic kidney disease.
Clinical Manifestations
- Upper urinary tract obstructions.
- Renal colic: Moderate to severe pain (flank to groin, lateral flank/lower abdomen indicates mid-ureter obstruction)
- Nausea
- Vomiting
- Hematuria
- Urgency, frequent urination (especially with lower ureter/ureterovesical junction obstruction)
- Lower urinary tract obstructions.
- Frequent daytime voiding
- Nocturia
