A 6.8 mm stone at the ureterovesical junction is very close to entering your bladder. To help it pass, doctors frequently prescribe an alpha-blocker like tamsulosin, which relaxes the muscles in your ureter. For managing pain and reducing inflammation, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are highly effective. Staying well-hydrated is also crucial to help flush the stone out. Since a 6.8 mm stone is on the larger side for passing naturally, please consult your doctor for the correct prescriptions and to monitor your progress safely.
