  • post voiding residual urine

OBJECTIVES: To determine whether postvoid urine is a risk factor for the development of lower urinary tract infections (UTIs) in nursing home residents.

DESIGN: Prospective surveillance with a follow-up period of 1 year.

SETTING: Six Norwegian nursing homes.

PARTICIPANTS: One hundred fifty nursing home residents.

METHODS: Postvoid residual (PVR) urine volumes were measured using a portable ultrasound. UTIs were registered prospectively for 1 year.

RESULTS: Ninety-eight residents (65.3%) had a PVR less than 100 mL, and 52 (34.7%) had a PVR of 100 mL or greater. During the follow-up period, 51 residents (34.0%) developed one or more UTIs. The prevalence of UTI in women was higher than in men (40.4% vs 19.6%; P=.02). There was no significant difference in mean PVR between residents who did and did not develop a UTI (79 vs 97 mL, P=.26). PVR of 100 mL or greater was not associated with greater risk of developing a UTI (P=.59).

CONCLUSION: High PVR is common in nursing home residents. No association between PVR and UTI was found.
