Nocturia in white and black male patients does not differ in etiology, a team
from SUNY Downstate College of Medicine in Brooklyn, New York, reported
in the Canadian Journal of Urology.

Matthew R. Epstein, MD, and colleagues analyzed 24-hour frequency volume charts completed by men aged 18 years or older seeking treatment for lower urinary tract symptoms at a Veterans Affairs urology clinic from 2008 to 2016. They classified patients as having nocturia owing to small bladder capacity (SBC), nocturnal polyuria (NP), mixed nocturia (SBC plus NP), or “other” (neither SBC nor NP). Among the white and black patients, 24% and 26%, respectively, had NP, 27% and 30% had SBC, and 30% and 28% had mixed nocturia. Overall, the investigators found no significant difference in the distribution of underlying nocturia etiology by race.

“Accordingly, race should not play a role in the evaluation of patients seeking treatment for nocturia,” they concluded.
