Hi, many thanks for the query!
Stone in the
ureter causes obstruction to urine outflow, so urine accumulates in kidneys causing so called swelling of kidneys i.e.
Hydronephrosis.
You need to do certain investigations- USG (Abdo-Pelvis), X-ray KUB,
RFT, LFT, Sr. Uric acid, Urine (Routine & Microscopy).
You haven't mentioned, exactly what Lung problem you have.
If you are drinking alcohol, stop it gradually.
For time being, you may take anti-spasmodics, pain killers with
your doctor's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
Wish you a good health.
Take care.
Regards.
