R30-R39: Symptoms and signs involving the urinary system

R34: Anuria and oliguria

Anuria and Oliguria are conditions that affect the urinary system. Anuria refers to a state where the body can't produce urine, often defined as a urine output of less than 50 milliliters per day. Oliguria, on the other hand, is a condition where urine output is less than usual, typically less than 400 milliliters per day. These conditions often indicate kidney disease or damage but can also be due to severe dehydration, certain medications, or blockages in the urinary tract. The main symptom is decreased urination. Without prompt treatment, these conditions can impede the body's ability to eliminate waste products, leading to a buildup of toxins in the blood that can cause serious health issues.
