Pyelitis is a medical term that refers to the inflammation of the renal pelvis, which is the part of the kidney where urine collects before flowing into the ureter. Pyelitis can occur as a result of a bacterial infection, and it is often associated with pyelonephritis, which is an inflammation of the kidney tissue itself.

The symptoms of pyelitis may include fever, chills, flank pain, nausea, vomiting, and frequent or painful urination. The condition can be diagnosed through a variety of tests, including urinalysis, urine culture, and imaging studies such as ultrasound or CT scan. Treatment typically involves antibiotics to eliminate the underlying infection, as well as supportive care to manage any symptoms.

It is important to seek medical attention promptly if you experience symptoms of pyelitis, as untreated infections can lead to serious complications, including kidney damage and sepsis.

Emphysema is a chronic respiratory disease characterized by abnormal, permanent enlargement of the airspaces called alveoli in the lungs, accompanied by destruction of their walls. This results in loss of elasticity and decreased gas exchange efficiency, causing shortness of breath and coughing. It is often caused by smoking or exposure to harmful pollutants. The damage to the lungs is irreversible, but quitting smoking and using medications can help alleviate symptoms and slow disease progression.
