Intensive medical management of ureteral calculi

Objectives. To compare two treatment regimens in patients with ureteral cal culi. One regimen (control arm) used routine drugs, and the second regimen (treatment arm) used the same routine drugs plus uncommonly used drugs. Methods. Between February and October 1998, 70 consecutive patients were ev aluated for symptomatic ureteral calculi. Thirty-five patients were randomi zed to a control arm and received ketorolac, oxycodone, and acetaminophen c ombination tablets and prochlorperazine suppositories. Thirty-five patients were randomized to the treatment arm and received the same medications plu s nifedipine XL, prednisone, and trimethoprim/sulfa combination tablets and plain acetaminophen. Stone passage rates, work days lost, emergency room v isits, surgical interventions, and possible side effects of the drugs were recorded. Results. The treatment arm (addition of nifedipine XL, prednisone, trimetho prim/sulfa, and plain acetaminophen) had higher (86% versus 56%) stone pass age rates and fewer lost work days (mean 1.76 versus 4.9), emergency room v isits (1 versus 4), and surgical interventions (2 versus 15). Both arms exh ibited similar potential drug side effects. Conclusions. The addition of a calcium channel blocking agent, steroids, an tibiotics, and more acetaminophen effected a higher stone passage rate and fewer lost work days, emergency room visits, and surgical interventions.
