We conducted an open, non-randomized experimental study as a first step to find out whether cooling of the feet may cause symptomatic lower urinary tract infection (UTI) in cystitis-prone women. Twenty-nine healthy women, aged 19–68 (mean 42.5) years, who had had three or more symptomatic episodes of UTI during the previous 12 months were included. They registered symptoms and carried out a strip urinalysis at each urination during a control period of 72 hours. Their lower legs and feet were then immersed in increasingly cold water for 30 minutes. Another 72-hour period of registration followed. Six subjects developed acute distal urinary symptoms at a mean of 55 (95% confidence interval 50 to 61) hours after the cooling, compared with none in the control period. Five of the six had bacteriologically verified lower UTI (P = 0.03 v. the control period). Cooling of the feet seems to provoke symptomatic lower UTI in cystitis-prone women. |
