Description: Oliguria is a medical condition characterized by a significant decrease in urine production, typically defined as less than 400 milliliters of urine in a 24-hour period in adults. This condition can be an indicator of underlying problems in the renal system or in the body’s overall function. Oliguria can be caused by various factors, including dehydration, acute renal failure, urinary tract obstruction, or conditions affecting blood flow to the kidneys. Associated symptoms may include fatigue, swelling, and in some cases, confusion. Oliguria is an important clinical sign that requires medical attention, as it can lead to serious complications if not properly treated. The evaluation of oliguria involves a thorough analysis of the patient’s clinical history, physical examinations, and laboratory tests to determine the underlying cause and establish an appropriate treatment plan. Monitoring urine production is crucial in medical settings, especially in critically ill patients, to assess renal function and response to treatment.
