E-Posters-Increasing Age Predicts Increasing Residual Urine Volume

Pdf Summary

A study conducted at Loyola University Chicago Stritch School of Medicine aimed to determine reference values for post-void residual volume (PVR) in patients referred to a tertiary urogynecology center. The study also aimed to identify patient characteristics associated with an elevated PVR, independent of age. The researchers performed a retrospective chart review on new patients presenting to the urogynecology clinic at Loyola University Hospital between June 2016 and December 2016. They collected data on demographics, pelvic floor symptoms, physical exams, and medical history related to urinary retention. Statistical tests were used to analyze associations between PVR and patient characteristics. A multivariable logistic regression model was used to calculate odds ratios for patient characteristics associated with PVR in the top age-specific decile.<br /><br />The study included 361 women, and the mean PVR was 40.69mL. The results showed that as age increased, PVR also increased significantly. Higher prolapse stage was associated with higher PVR. The study found that women with prolapse stage 2-4 had a 3.46 times higher odds of having a PVR above the 90th percentile for their age compared to women with prolapse stage 0-1. The odds were also higher for women with a history of stroke, narcotic use, and urinary urgency/frequency.<br /><br />The study provides reference values for PVR in patients referred to a urogynecology center. It suggests that PVR increases with age and identifies specific patient characteristics associated with elevated PVR. The findings can help guide management and treatment decisions for patients with urinary incontinence and other pelvic floor symptoms. However, the study also notes that no strong data currently exists to support different management or treatment based on PVR, highlighting the need for further research in this area.
