Removing Small Asymptomatic Kidney Stones Is Beneficial – Consumer Health News

THURSDAY, August 11, 2022 (HealthDay News) — According to research published in the magazine’s August 11 issue New England Journal of Medicine.

Mathew D. Sorensen, MD, of the University of Washington School of Medicine in Seattle, and colleagues conducted a randomized trial in which remaining small, asymptomatic stones were removed in 38 patients and not removed in 35 patients during endoscopic removal of the urethra or contralateral kidney stones.

The researchers found that the treatment group had longer to relapse than the control group after an average follow-up of 4.2 years. Compared to the control group, the restricted mean time to relapse was 75% longer in the treatment group (1,631.6 versus 934.2 days). Compared to the control group, the treatment group had a lower risk of relapse (relative risk, 0.18), with 16 and 63% of patients in the treatment and control groups, respectively, having a relapse. A median of 25.6 minutes was added to surgery time with treatment. Within two weeks of surgery, five and four patients in the treatment and control groups, respectively, had an emergency department visit.

“Removing small, asymptomatic kidney stones during surgery for a ureteral or contralateral stone resulted in fewer subsequent ED visits and surgeries and less stone growth than leaving secondary stones in place,” write the authors.
