Differential Diagnosis for Infected Kidney Stone
- Single most likely diagnosis
- Pyelonephritis: This is the most likely diagnosis as an infected kidney stone can cause an infection of the kidney, known as pyelonephritis, which is a common complication of kidney stones. The stone can block the flow of urine, leading to an accumulation of bacteria and subsequent infection.
- Other Likely diagnoses
- Sepsis: If the infection from the kidney stone spreads to the bloodstream, it can cause sepsis, a life-threatening condition. The presence of a kidney stone increases the risk of developing sepsis, especially if the stone is obstructing the flow of urine.
- Urosepsis: This is a type of sepsis that occurs when a urinary tract infection (UTI) spreads to the bloodstream. An infected kidney stone can cause a UTI, which can then lead to urosepsis.
- Perinephric abscess: An infected kidney stone can cause an abscess to form around the kidney, known as a perinephric abscess. This is a collection of pus that can be life-threatening if not treated promptly.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Emphysematous pyelonephritis: This is a rare but life-threatening condition that occurs when an infection of the kidney causes gas to form in the tissue. It is more common in people with diabetes and can be deadly if not treated promptly.
- Xanthogranulomatous pyelonephritis: This is a rare type of kidney infection that can cause the kidney to become enlarged and filled with pus. It is often associated with kidney stones and can be deadly if not treated promptly.
- Rare diagnoses
- Malacoplakia: This is a rare condition that causes abnormal growths to form in the urinary tract, including the kidneys. It is often associated with kidney stones and can cause symptoms similar to an infected kidney stone.
- Tuberculosis of the kidney: This is a rare type of kidney infection that is caused by the bacteria that cause tuberculosis. It can cause symptoms similar to an infected kidney stone and can be deadly if not treated promptly.
