How Long Does It Take to Pass Kidney Stones After Lithotripsy

After undergoing extracorporeal shock wave lithotripsy (ESWL), patients may pass the broken stone fragments within 1 day, 1 week, or even up to 2 weeks. In some cases, the stone particles may be so small that they go unnoticed during excretion. It is important to note that regardless of whether the stones have passed, patients should schedule a follow-up appointment with their doctor 1–2 weeks after the procedure. Imaging tests such as X-rays or ultrasounds are typically used to confirm whether the stones have been fully expelled.

If the stones have not passed within 1–2 weeks, a second lithotripsy session may be recommended. However, if the stones persist after 2–3 treatments, alternative treatment options should be considered. These may include ureteroscopy or percutaneous nephrolithotomy, depending on the size and location of the remaining stones. Timely follow-up care is crucial to prevent potential complications such as infection or further blockage. Patients are also encouraged to stay well-hydrated and follow any additional post-treatment instructions provided by their healthcare provider.
