Few urogenital reactions were described ( Table 6 and Table 7). Hemoglobinuria was described as an adverse reaction seen after transfusion of stem cell products 39, 51, 56, 73. However, hemoglobinuria is often attributed to erythrocyte debris in the transplant material and has thus not been interpreted as being caused by DMSO 39, 73. The other urogenital reactions ( Table 6 and Table 7) all occurred after DMSO instillation in the bladder 38, 49, 97.
