Ureteral stones occur in either of the ureters that carry urine from the kidney to the bladder. Small ureteral stones are common and can easily pass through the urine. A big stone obstructs the passage of urine, thus it needs to be treated by surgery. At Delhi Urology Hospital, one can get the best ureteric stone surgery in Delhi from expert urologist Dr. Niren Rao. Severe upper flank pain, lower abdominal pain radiating downwards, burning or painful urination, nausea, vomiting, and discoloured or bloody urine are all symptoms. To learn more about the treatment process or surgery, visit the hospital.
