Abstract (original English)

Introduction Severe hemorrhagic cystitis (HC) is still a common complication after allogeneic hematopoietic stem cell transplantation, which affects the quality of life of patients, and may even cause kidney failure. This study reports the clinical effect of adjuvant treatment of adipose-derived mesenchymal stem cells (ADSCs) on severe refractory HC after of reduced intensity conditioning haplotype high-dose peripheral blood hematopoietic stem cell transplantation (RIC-PBSCT) in one case. Patient concerns A 53-year-old female patient with acute myeloid leukemia (FLT3-ITD) at high risk received RIC-PBSCT. The patient was relieved with complete donor chimerism of 99.01%, and normal hemogram. However, the patient developed frequent urination, urgency, and dysuria with gross hematuria with blood clots and difficult urinating, especially at night and early in the morning. There were obvious hyperemia and bleeding points in the mucosa of the posterior wall of the bladder. Diagnosis The patient was diagnosed as delayed HC of degree IV. Interventions and outcomes The patient was treated with antiviral drugs, urine alkalization, and diuretic drugs for more than 1 month, but no significant effect was obtained. Thus, the patient was then given ADSCs (1 × 106 kg per kg of body weight, infused once a week for a total of 3 infusions). Symptoms of frequent urination, urgency, and dysuria that
