What is the potential complication of untreated pyelonephritis?

The potential complication of untreated pyelonephritis is kidney damage or failure. Pyelonephritis, an infection of the kidney, can lead to serious consequences if not adequately treated. The infection can cause inflammation and scarring of kidney tissue, which may diminish kidney function over time. This scarring can be irreversible, leading to chronic kidney disease and, in severe cases, kidney failure.

While the other conditions listed can certainly arise from various health issues, they are not directly associated with untreated pyelonephritis. Chronic heart disease may occur due to other systemic issues or diseases but is not a direct consequence of kidney infections. Similarly, stomach ulcers and liver dysfunction stem from different underlying conditions and are not complications linked to pyelonephritis. Understanding the specific risks associated with untreated urinary tract infections can help inform better management and treatment strategies.
