Risk Factors
When it comes to dehydration, there are several risk factors to be aware of. These include excessive heat and sun exposure without proper hydration, as well as conditions such as vomiting and diarrhea. On the other hand, oliguria caused by renal failure usually occurs alongside another medical condition. There are various risk factors associated with this, including a previous or current diagnosis of peripheral artery disease, diabetes, high blood pressure, heart failure, and certain types of cancer. Additionally, advanced age and hospitalization in an intensive care unit for a serious condition can also increase the likelihood of experiencing oliguria.
Diagnosing Oliguria
When it comes to diagnosing the root cause of oliguria, there are several approaches available. One commonly used method involves a 24-hour urine collection to accurately measure the amount of urine a patient produces in a day. In addition to this, doctors may also obtain urine samples for analysis, as well as conduct blood tests to measure levels of creatinine and urea. These two markers are indicative of kidney function. In cases where kidney damage is suspected, further evaluation can be done through imaging techniques such as ultrasound or CT scan. In some instances, a biopsy may be necessary to gather more information.
