if the stone is at the level of ischial spine, it must be small in size, hence passable per urethra. Treatment you took will not help pass the stone out. It was wrong treatment. If you dot have pain
now then try oral forced diuresis:
1take anti spasmodic like drotaverine
hydrochloride 80 mg with diuretic like lasilactone 50 mg in the morning and drink plenty of water. Do not be impatient, stone will out but not so quickly as you expect. Oral diuresis should continued for 20 days then break for 10 days for three months. Then stop medications, save
the stone and get its chemical analysis done. During the treatment if you get the pain take drotaverine every 6 hours till pain settles down. If you have pain at the time of taking medicines in the morning then do not take lasilactone> when pain settles down take drotin
and diuretic from next morning. If the stone recurs then try to find out underlying cause.
