Study Notes

Ketonuria occurs in patients with Type 1 Diabetes Mellitus (DM Type 1) and in pregnant women.
Proteinuria indicates excess protein in urine, often seen in conditions like preeclampsia.
Preeclampsia is characterized by new onset hypertension and signs of organ injury, particularly affecting the kidneys.
Organ injury in preeclampsia typically resolves within days or weeks after delivery.

Glucosuria is the presence of glucose in urine, often related to diabetes.
Diabetes is a chronic health condition marked by high blood glucose levels.
It arises when the pancreas produces insufficient insulin or when the body cannot effectively use the insulin produced.

Pyuria is indicative of urinary tract infections (UTIs), which occur when bacteria infect the urinary tract.
Hematuria refers to the presence of blood in urine and can be associated with glomerulonephritis.
Glomerulonephritis involves damage to the glomerulus, the filtering part of the kidneys.

Urinalysis is considered the foundation of laboratory medicine.
The invention of the microscope in the 17th century advanced the examination of urinary sediment.
Hippocrates authored the book “uroscopy” in the 5th century BCE, laying groundwork for urinalysis.
Albuminuria was discovered by Frederik Dekker in 1694, and Richard Bright introduced urinalysis in routine medical examinations in 1827.
Urinalysis remains crucial due to the easy collection and inexpensive nature of urine specimens.

Urine consists of 95% water and 5% solutes, including organic and inorganic solids.
Organic solids include urea, creatinine, and uric acid; inorganic solids contain sodium, potassium, and chloride.
Other components include hormones, vitamins, and medications.

Key indicators for identifying urine include elevated levels of creatinine, urea, sodium, and chloride compared to other body fluids.

Normal daily urine output ranges from 1200 to 1500 mL.
Urine volume fluctuates based on fluid intake, fluid loss from non-renal sources, variations in ADH secretion, and the need to excrete dissolved solids.
