An unusual cause of ureteral obstruction in a renal transplant recipient: ureteric aspergilloma.

Mycotic infections in various organ transplant recipients represent severe and often fatal complications. Aspergillosis isolated from the urinary tract occurs quite infrequently in renal transplant recipients. Besides, fungus balls are rare causes of ureteral obstruction. We report a 51-year-old patient with the diagnosis of ureteral obstruction caused by aspergillosis in the early post-renal transplant period, who unfortunately died with the clinical picture of disseminated infection and its complications.
