Suppuration (formation or discharge of pus) of the kidney is called which term?

• A. Nephritis
• B. Hydronephrosis
• C. Polycystic kidney disease
• D. Nephropyrosis

Answer: (D)

Suppuration is the formation of pus due to a bacterial infection. When this process occurs in the kidney itself, the term used is nephropyrosis, indicating pus within the renal tissue. This distinguishes it from simple inflammation (nephritis), which is primarily swelling and immune response without pus; from hydronephrosis, which is dilation of the kidney’s collecting system due to obstruction; and from polycystic kidney disease, which involves multiple cysts in the kidney. Nephropyrosis specifically conveys the presence of purulent material in the kidney, making it the best fit for suppuration of the kidney.
