Harnvolumen
Harnvolumen refers to two related but distinct concepts in urinary physiology. One is the amount of urine produced and excreted by the kidneys over a period, most commonly a 24-hour interval. The other is the bladder’s storage capacity, i.e., the maximum volume the bladder can hold before the urge to void becomes noticeable. Both measures are used to assess kidney function, fluid balance, and lower urinary tract health.
Normal ranges vary by context. Daily urine volume in adults is typically about 800 to 2000 milliliters,
Measurement and assessment methods include a 24-hour urine collection to determine total daily volume, and bladder
Clinical relevance: very low volumes (oliguria, typically <400 mL/day) can indicate dehydration or impaired kidney function,
