Materials and Methods: We conducted a retrospective study of 841 patients who underwent ESWL for primary treatment of urinary calculi between 1985 and 1987. Charts were reviewed for stone characteristics, outcomes and associated laboratory data. Followup 6 to 9 years later was done by mail and telephone interviews. Results: Followup data were available for 436 patients (52 percent). Overall, stones recurred in 51 percent of the 436 patients at a mean followup of 7.1 years. Late recurrences were common, and were noted in as many as 70 percent of the patients after 9 years. This rate is greater than what has been previously reported after other treatments. Cox regression analysis indicated that the major risk factors associated with recurrence were male gender (relative risk 1.406, p less than 0.05) and multiple stones (relative risk 1.777, p less than 0.05). Conclusions: The frequent late recurrences support the speculation that ESWL might lead to greater recurrence rates. Therefore, the cost-effectiveness of ESWL versus other modalities for stone removal warrants more long-term evaluation.
