title: Gallstone recurrence after successful lithotripsy.
abstract: We report the recurrence rate of gallstone within 5 years after successful lithotripsy. One hundred and fifty consecutive patients (solitary stones, 102 patients; multiple stones, 48 patients) were followed up for a median of 42 months (range 6-72) after stone clearance and cessation of bile acid therapy. No patient received any therapy to prevent recurrence. Thirty-seven patients developed recurrent gallstones. Probabilities of recurrence were (mean +/- SD) 6.6% +/- 2%, 15.7% +/- 3%, 22.8% +/- 3.6%, 29.7% +/- 4.5%, 32.2% +/- 5% at 1, 2, 3, 4 and 5 years, respectively. The recurrence rate was lower in patients who had solitary stones than in patients with multiple stones (26.1% versus 47% at 5 years, respectively; p<0.009 - log rank test). Only five patients developed recurrent symptoms or stone complication (14%). We conclude that the recurrence rate after successful lithotripsy is lower than expected from dissolution studies, due to a low recurrence rate in patients who had solitary stones.
