<prompt> 45 yr old male with Ho repeated attacks of UTI, X-ray KUB showing radio opaque shadow -Ureteric pathologyProstate pathologyTesticular pathologyStricture urethra  <response>: Ans. is a i.e., Ureteric pathology Ureteric Stones Almost always associated with UTI Usually radio opaque X ray KUB CT KUB is the gold standard for imaging ureteric stones, with the vast majority 99 being radiodense. Stones 1 mm in size are visualised, with the specificity of helical CT as high as 100 Calculi size and location as well as ureter anatomy are important factors in determining likelihood of spontaneous calculi passage with stones less than 5 mm having high likelihood of passing down the ureter. However even small calculi may be impossible to pass if it is located at the pelvicoureteric junction or in patients with ureteral strictures. Passage of calculi may be facilitated with tamsulosin and nifedipine. In calculi 10 mm or with failed conservative management, urological procedures such as extracorporeal shock wave lithotripsy ESWL, ureteroscopic lithotripsy or percutaenous nephrostomy may be required.
