Welcome to health care magic.
1.The report suggest dilated pelvis-calyx with upper hydro-
ureter - the most possible cause could be cute to the mid ureic calculus.
2.Rest of the scan appears normal -
kidney site appears normal on both sides.
3.The stomach pain could be due to the ureteric calculus.
4.The Treatment depends on the severity of the symptoms - if less symptomatic - treatment will be excess of water with symptomatic treatment.
5.In case os severe symptoms - a CT KUB ( computer
tomography of kidney ureters,
urinary bladder ) evaluation - depending on the size of calculus either interventional or symptomatic treatment. Good luck.
Hope i have answered your query,
any thing to ask do not hesitate to ask.
