you have a stone lodged at the junction between the bladder and the ureter
(tube where urine passes that connects the kidney
to the bladder). Depending on the size of the stone treatment options 1) conservative - wait for the stone to pass out on its own with adequate pain control 2) endoscopic treatment - put in a scope and remove the stone by basket or laser
- fragmentation by using shock
waves ( less invasive) .
Like I said the treatment options would be determined depending on the stone size and availability of equipment and expertise in your area.
