My sister was diagnosed to have left mid uretric calculi measuring 12 mm. She underwent left URS with double DJ stent procedure 2 weeks ago. From POD 1, she was complaining of pain in left flank and pain while micturation. For a week she had hematuria and then it eventually became clear. On 17th June 2016 at 1 PM, her stent was removed as scheduled. Immediately after stent removal, she was fine. But soon after couple of hours, she started experiencing worst pain and had not passed urine till 10 PM (at time of writing this). Her pain did not go away with prescribed analgesics. I spoke with the surgeon who performed the procedure. He said that pain may be caused by obstruction caused by a blood clot or a particle in the ureter. He advised to continue analgesics and come to hospital immediately if pain did not subside by next day morning. I am worried that it could be a complication of stenting. So far there is no fever. What can be further done for her?
