A:Chances of spontaneous passage are more than 90% for stones less than 5 mm at the lower end of ureter. Most of ureteric stones pass out during first 3 to 4 weeks after the first pain, meaning that chances of spontaneous passage go down substantially if it has not passed during earlier weeks. You may thus safely wait for its passage during this period. Medications usually prescribed during this period are NSAIDs and alpha blockers; these help keep you pain-free and improve the chances of passage of the stone. One should not wait for the passage if there is fever associated with pain as it means infection associated with obstruction. Usual advise of taking excess fluids has not been proved to be effective. In case of excessive pain, associated fever and non passage after couple of weeks after the first pain, it is advisable to have such a stone removed with help of ureteroscopy.
