Residual Urine, UTIs Not Linked in Nursing Home Residents

Residual urine in nursing home residents is not associated with UTIs, Norwegian researchers reported in the Journal of the American Geriatrics Society (2008;56:871-874).


They measured post-void residual volume (PVR) in 150 residents of six nursing homes in Norway and for one year monitored development of UTIs. A total of 98 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, one or more UTIs developed in 51 subjects (34%). No significant difference in mean PVR was observed between residents who did and did not experience a UTI. A PVR of 100 mL or greater was not associated with an increased UTI risk.
