Brief Answer: To rule out Urinary tract infection Detailed Answer: Namasthe Welcome to Healthcare-Magic Greetings of the day I would like to answer all your query in continuity. Presence of pain in abdomen, and in the presence of foreign object like stent in the ureter along with presence of fever: One should rule out Urinary tract infection as the cause of symptoms. I would suggest you to get Urine Microscopic examination and Ultrasound abdomen to rule out Urinary tract infection as the cause of symptoms. If the investigation are normal and also there is no evidence of surgical site infection then there seem to be no cause of concern. Presence of any foreign matter in body like stent may predispose to occurence of infection. The prognosis for whether the tissue removed from ureter recurrs depends on type of tissue - histopathology of the tissue. The prognosis of Renal function improving post surgery depends on the duration of obstruction and pathology of the tissue of ureter being removed. It would be very useful if you could get back with detailed pre-operative history, duration of symptoms, detailed investigation including the renal scan, ultrasound and Renal function test. Also let me know about the Histopathology report of excised tissue of the ureter. Waiting for your reply. Take Care Best Regards Dr Deepak Kishore MBBS,MS,MCH Consultant Surgeon
