Aims: No one has assessed urodynamic studies (UDS) to determine those steps that elicit the greatest anxiety, distress, and pain in children. We sought to systematically evaluate a child's UDS experience to mollify these reactions.
Methods: Prospective study involving children aged ≥5 undergoing UDS over a 6-month period (from 10 December 2018 to 22 May 2019). Upon arrival, patients completed a visual analog scale for anxiety (VAS-A, 0-10) about the upcoming procedure. A research assistant assessed the patient's behavior during each major step of UDS using a validated brief behavioral distress scale. Nursing staff also obtained patients' pain ratings (0-10) for these key elements. Immediately after UDS, each child completed a posttest VAS-A along with a survey about the UDS experience.
Results: A total of 76 UDS were observed; almost half included sphincter needle electromyography (EMG). Mean patient VAS-A scores were 2.3 before UDS, compared to 0.8 afterward (P < .001). The highest proportion of distressful behaviors were observed during EMG needle (31%) and urethral catheter (29%) insertion, in agreement with the highest mean pain scores of 3.2 and 2.7, respectively. Fifty-four percent of children reported not being completely aware of what was going to happen before the procedure and 50% of those patients exhibited at least one interfering or potentially interfering behavior. Similarly, 60% of children with no prior history of UDS exhibited at least one interfering or potentially interfering behavior.
Conclusions: EMG needle and urethral catheter placement, initial urodynamic testing and not knowing what to expect were associated with greater pain and distress during pediatric UDS.
