Kidney Stones Stuck in the Ureter: How Long Does It Take to Pass?

Passing a kidney stone can be a painful and unpredictable experience. When a stone becomes lodged in the ureter, it typically takes at least three days to pass naturally, depending on its size and location. However, not all stones can be expelled without medical intervention. In such cases, procedures like extracorporeal shock wave lithotripsy (ESWL) or laser lithotripsy may be necessary.

The ureter has three natural narrow points, where stones are more likely to get stuck. Larger stones may become trapped at these narrow areas, leading to blockage and swelling. This blockage can cause inflammation and discomfort, making it even harder for the stone to pass.

Drinking plenty of water is crucial during this time. Hydration helps flush the urinary system and may encourage the stone to move down and eventually pass. Once the stone begins to shift, it often takes about three days to fully exit the body. However, if the stone is too large to pass naturally, extracorporeal shock wave lithotripsy (ESWL) is often recommended. This non-invasive procedure breaks the stone into smaller pieces that can then be passed more easily with urine.

If ESWL is not effective, holmium laser lithotripsy may be required. This procedure uses laser energy to break up the stone with high precision. After either procedure, inflammation and swelling may still be present, so doctors often prescribe anti-inflammatory medications to ease discomfort and promote healing.

It's important to note that delayed treatment can lead to serious complications, such as hydronephrosis (swelling of the kidney due to blocked urine flow) and reduced kidney function. During this time, patients should follow a light diet and continue to drink plenty of fluids to support the healing process.

In summary, while some stones may pass within a few days, others require medical assistance. The total time for clearance can vary from one day to up to a week, especially if multiple treatments are needed. Always consult a healthcare provider for proper diagnosis and management.
