SummaryIn cases of stone in the lower ureter, a conservative attitude should be adopted only if the patient is symptom free and there is no significant ureteral obstruction.Properly used, the Dormia basket is a safe and effective instrument.In a consecutive series of 126 cases of stone in the ureter where the Dormia basket was used, the stone was extracted immediately in 82 (65 %).When the stone is stuck in the intramural ureter it should be removed by transurethral ureterolithotomy.
