Alum irrigation for the treatment of adenovirus induced hemorrhagic cystitis in a kidney transplant recipient.

Adenovirus is a rare cause of hemorrhagic cystitis in the transplant population. We present a case of a forty-one-year-old man with end-stage renal disease who underwent living unrelated donor kidney transplant in 2016. In 2018 he presented with acute onset gross hematuria and dysuria, with serologic testing and immunohistochemical stains of biopsy specimens positive for adenovirus. He was treated with reduction in immunosuppression, cystoscopy with evacuation of clots, and alum bladder irrigation. His hematuria resolved almost immediately with no recurrence to date. This case demonstrates the efficacy and safety of alum irrigation in patients with adenovirus hemorrhagic cystitis.
