Objective: To prospectively evaluated the utility of urodynamic evaluations (UDS) ordered in a tertiary referral center as part of a quality improvement project. Methods: Patients with UDS ordered by 3 subspecialty physicians were included. Physicians were surveyed when ordering UDS and at the post-UDS clinic visit to assess indications for UDS, pre- and post-UDS diagnosis, treatment plan, confidence level, and perceived helpfulness of UDS. UDS trained nurses conducting studies were surveyed on patient reported reproducibility of their symptoms and perceived difficulty of UDS. Results: From April 2017 to October 2017, 127 UDS were included of which 102 met study criteria. UDS were done for neurogenic (23%) and non-neurogenic lower urinary tract symptoms (76%). The majority were conducted for incontinence evaluation (79%), or after prior lower urinary tract surgery (33%). UDS nurses reported 90% of UDS fully or partially reproduced patient symptoms. Nurses found 18% of UDS difficult due to catheter malfunctions, physical limitations, and communication abilities. Post-UDS, providers found 97% of UDS interpretable. UDS resulted in a change in treatment plan in 78% of patients. On a Likert scale, mean pre-UDS confidence level was 2.9 ± 0.8 (range 0-5). This increased to 4.1 ± 0.6 post-UDS with 76% of evaluations having a change of at least 1 point. Conclusion: UDS in a tertiary referral center result in change in patient treatment plans over three-fourths of the time with high rates of interpretability.
