Study Notes

Acute Urinary Retention (AUR)

AUR is the sudden inability to empty the bladder, considered a medical emergency.
Common causes include benign prostate hyperplasia, urethral stricture, urinary tract stones, nerve problems, and aging.
Symptoms include severe lower abdominal pain, inability to urinate, reduced urine flow, signs of infection, and bladder swelling.

Urinary Tract Infections (UTI)

UTIs occur when bacteria infect part of the urinary tract and are more prevalent in women.
In men, underlying causes like urethra stricture, STIs, bladder stones, or prostate issues must be investigated.
UTIs can be categorized into lower UTIs (bladder and urethra) and upper UTIs (kidneys and ureters), with upper UTIs posing a higher risk of kidney damage.
Symptoms include burning sensation during urination, cramping, increased urination frequency, cloudy urine, fever, confusion in the elderly, and potential nausea/vomiting.

Kidney Stones (Renal Calculi)

Kidney stones are hard lumps that can form in one or both kidneys, often causing nausea when moving down the ureters.
Small stones may pass unnoticed, but larger stones can block the urinary system.
Symptoms include persistent back pain, intense pain during episodes (renal colic), increased urination urgency, nausea/vomiting, and blood in urine.

Acute Kidney Injury (AKI)

AKI is characterized by sudden kidney failure or damage, leading to waste product build-up in the blood within hours or days.
Symptoms include nausea/vomiting, oliguria (less than 100ml urine in 24 hours), dehydration, confusion, and abdominal/back pain.
Causes of AKI can include reduced blood flow, heart issues, kidney blockage from prostatomegaly, tumors, or kidney stones.
Treatment varies based on the cause and may include fluid administration, antibiotics, medication adjustment, or urinary catheterization.

Chronic Renal Failure (Chronic Kidney Disease - CKD)

CKD is a long-term condition where kidney function gradually declines, often associated with aging.
Early stages of CKD usually present no symptoms; advanced cases may show tiredness, swelling, shortness of breath, nocturia, and high blood pressure.
Major contributing factors include hypertension, diabetes, high cholesterol, kidney infections, and long-term medication use.
Treatment includes lifestyle changes, medications, dialysis, or kidney transplant as necessary. CKD increases the risk of cardiovascular diseases.
