CO2 cystometry in myelodysplasia.

Findings on consecutive CO2 cystometry in 57 myelodysplastic children are reported. Twenty-six children had autonomous bladders and twenty had reflex bladders. Boys were equally distributed among the 2 common bladder types but girls were found to be predominantly in the autonomous bladder group. Different ancillary parameters were determined such as neurologic level, intelligence quotient, the prevalence of urinary tract infection, intravenous pyelography abnormalities and shunting, and the presence or absence of perianal sensation, bulbocavernosus reflex and erections. There appeared to be no correlation between any of these factors and bladder type except for a lower frequency of urinary infections in the autonomous bladder group.
