Abstract

INTRODUCTION AND OBJECTIVES An elevated post void residual (PVR) is traditionally thought to be associated with an increased risk of urinary tract infections (UTI) and may be considered an indication for clinical intervention. We sought to describe the associations between measured PVR and self-reported symptoms and UTI in patients seeking treatment for lower urinary tract symptoms (LUTS). METHODS Data were obtained from the LURN Observational Cohort Study. PVR and self-reported history of UTIs were collected at the baseline clinic visit. Women were asked if they had ever had more than two UTIs while men were asked if they had ever had any UTIs. Lower urinary tract symptoms (LUTS) were collected using the AUA-SI and the LUTS Tool. Comparisons by sex were made using Wilcoxon two-sample and chi-square tests. RESULTS 48% of women reported more than 2 UTIs and 22% of men reported having had a UTI (Table). Median measured PVR was not different by UTI status for males or females (median PVR [ml] for UTI vs. no UTI: 29.5 vs. 27 for males and 26 vs. 25.5 for females). There was no difference in elevated PVR (>200ml) by UTI in either sex (11.1% vs. 7.7% in males and 2.7% vs. 2.1% in females). Self-reported symptoms of incomplete emptying were slightly higher in females who had more than 2 UTIs compared to those that did not (median LUTS Tool score 2 [sometimes] vs. 1 [rarely], p=0.004; median AUA score 2 [< half the time] vs. 1 [<1 time in 5], p=0.006), but these scores did not differ between men with any previous UTIs compared to men no previous UTIs. CONCLUSIONS The PVR in care-seeking people is not associated with the self-reported incidence of recurrent UTI, despite some association with retention symptoms in females. Our results suggest that an elevated PVR may not be associated with recurrent urinary tract infections.
