Pediatric cystectomy for refractory cystitis post-bone marrow transplant in dyskeratosis congenita: A case report

We present a case of refractory cystitis after BK-virus associated hemorrhagic cystitis following bone marrow transplantation requiring cystectomy in a 17-year-old female with genetically confirmed dyskeratosis congenita, a telomere(definition) disorder characterized by early bone marrow failure. She presented with a contracted, small bladder with intense urinary symptoms non-responsive to conservative therapy and requiring opioids for pain control. Cystectomy is a rare, final surgical treatment for benign bladder conditions, especially among younger patients, and she experienced successful resolution of symptoms and cessation of chronic opioids post-intervention.
