Continuing Education Activity Oliguria is a frequently encountered clinical condition that can arise due to either prerenal, renal, or post-renal abnormalities. It has various etiologies and management is dependent on the underlying cause(s). In order to avoid renal failure, the providers should not only keep in view the etiology and management of oliguria but also the various risk factors and precipitating factors as well. This activity reviews the evaluation and management of oliguria and highlights the role of the interprofessional team in improving care for patients with this condition. Objectives: • Identify the etiology of oliguria. • Describe the appropriate evaluation steps for assessing oliguria. • Summarize the management options for oliguria. • Explain the importance of collaboration and communication amongst the interprofessional team to enhance delivery of care for patients with oliguria. Introduction Oliguria is defined as urinary output less than 400 ml per day or less than 20 ml per hour and is one of the earliest signs of impaired renal function. Etiology Oliguria can be the result of various causes that can be apparent or subclinical. Prerenal Causes: • Hypovolemia: decreased effective blood volume secondary to less fluid intake, bleeding, gastrointestinal fluid loss (diarrhea, vomiting, or nasogastric suction), renal losses (diuretics or glycosuria), third-spacing of fluid (ascites, pleural effusion), trauma, surgery, burns, sepsis, anaphylaxis, hepatic ...

Oliguria is the medical term for low urine output. If you have a blockage, your kidneys are producing urine but you aren’t able to excrete it. If you aren’t producing urine, you may have diseases of the kidneys, heart or lungs. The best way to treat oliguria depends on what is causing the low urine output. Overview What is oliguria? Oliguria is a medical term for low urine output (how much you pee). In the case of an adult, this means less than 400 milliliters (mL) to 500 mL (around two cups) of urine per 24 hours. The numbers depend on weight in terms of children and infants. For an infant, the output is less than 1 mL/kilogram (kg)/hour, while oliguria in children refers to an output of less than 0.5 mL/kg/hr. What’s the difference between oliguria, anuria and polyuria? These words and conditions are all related. They refer to how much urine you produce. The definition of oliguria is low urine output, while anuria means no urine output. Polyuria means excessive urine production. Paying attention to urine has been a medical tool for thousands of years. Healthcare providers look at how much or how little you pee, what things are found in your pee (like blood or protein) and what color your pee is. Your healthcare provider, and you yourself, can learn important things by monitoring urine output and traits. Who is affected by oliguria? Low urine output can happen to anyone. It’s more likely to happen to people who have certain types of kidney diseases that can lead to acute ...
