In situ ESWL for ureteric calculi is associated with good stone clearance rates but is it without significant morbidity? A review of 189 patients with single ureteric calculi (150 upper ureter, 39 lower ureter calculi) revealed an 89% stone clearance for upper ureteral calculi and 80% stone clearance for lower ureteral calculi. However 11% of patients with upper ureteral calculi and 20% of patients with lower ureteral calculi required additional intervention for complications or failed treatment. In situ ESWL may not be the optimum therapy for all ureteric calculi especially those in the lower ureter.
