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, also, proximal to obstruction- Hydroureter.
If this obstructed urine gets infected, it causes inflammation in kidney & ureter, also, renal parenchyma is thinned out due to prolonged obstruction causing decrease in renal function.
Hence, a stent (DJ) is placed starting from renal pelvis through ureter upto bladder, so that infected urine is drained, obstruction is bypassed,
inflammation is reduced.
After say 15 days, (duration depends on extent of inflammation), of DJ stenting, stones can be removed.
To know more about renal function, you need to do-
DTPA renal scan renogram.
First you must do some basic investigations like-
CBC, RFT, Urine (R/M), USG KUB.
Take antispasmodics, antibiotics, diuretics with your Urologist's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
If Sr. Uric acid is raised, start uric acid synthesis inhibitors like allopurinol, urine alkalizing agents with your Urologist's opinion.
Wish you a good health.
Take care.
Regards.
