A patient with a ureteric stone and fever, rigors or raised inflammatory markers has an obstructed, infected kidney until proven otherwise. Antibiotics alone do not reach an obstructed system well.
Take blood and urine cultures, start intravenous antibiotics and arrange urgent decompression by ureteric stent or percutaneous nephrostomy. Definitive stone treatment waits until the infection has settled.
- Suspect an obstructed, infected kidney in any stone patient with fever.
- Take blood and urine cultures before starting antibiotics.
- Arrange urgent drainage by stent or nephrostomy alongside antibiotics.
- Delay definitive stone surgery until infection has resolved.
