Brief Summary:
Urodynamic testing is used to help diagnose causes of urinary incontinence and voiding dysfunction The purpose of the urodynamic test is to gain insight into the patients urinary symptoms and assist in making a diagnosis Catheter insertion and manipulation during the test can be uncomfortable for the patient Lidocaine gel has not been used routinely during urodynamic testing However it is used routinely during outpatient cystoscopy and with any urethral catheterization The investigators proposed that lidocaine numbing gel could be used without compromising test findings
The study included 110 adult women The purpose was
1 Determine whether the use of topical lidocaine during urodynamic testing decreases patient discomfort during the procedure
2 Evaluate whether the use of topical lidocaine affects the urodynamic results

Detailed Description:
Topical Lidocaine For Urodynamic Testing A Double Blinded Randomized Control Trial
Hypothesis aims of study
1 Determine whether the use of topical lidocaine during urodynamic testing decreases patient discomfort during the procedure
2 Evaluate whether the use of topical lidocaine affects the urodynamic results
Study design materials and methods The hospital IRB approved the study Women with symptoms of stress urinary incontinence SUI scheduled for a urodynamic study UDS were eligible to participate Women presenting with predominant overactive bladder symptoms were excluded Participants were randomized on the day of the procedure using Random Allocation Software Version 10 All were blinded to the study arms until completion of final data analysis Participant randomization assignment was known only to an independent research nurse and the dispensing pharmacist The study consisted of transurethral administration of 5 ml lidocaine 2 gel or surgilube gel in the study and control arms respectively 10 minutes before catheter insertion Prior to testing a 24 hour bladder diary and the Pelvic Floor Distress Inventory - Short Form 20 were completed During the UDS participants were asked for sensory information including desire to void and maximal cystometric capacity MCC Urethral pressure profiles were obtained at an infused volume of 200 ml Provocative measures were performed to assess SUI Using a Likert scale pain was assessed prior to and after catheter insertion after performing the urethral pressure profile and at the completion of the study The primary outcome pain after urethral pressure profile UPP was compared between the two groups Comparisons of the bladder diary and UDS results were made between study and control arms individually and in-between groups
Statistical methods The effect of lidocaine on patient pain as reported during multiple time-points during the UDS was evaluated using repeated measures analysis via mixed effects regression with a random patient-specific intercept This approach allows the evaluation of the overall pain experience as well as baseline-adjusted comparison at individual time-points Comparisons were done using t-tests for continuous variables Chi-squared test for categorical variables Wilcoxon rank-sum test Lins Concordance Correlation Coefficient CCC and a z-test The CCC provides a generalization of Pearsons correlation coefficient that measures how well the data align with the diagonal representing equal values for the two measurements as opposed to any straight line Agreement is stronger than correlation Specifically the agreement between mean void volume and volume at strong desire as well as between maximum void volume and volume at MCC were computed separately for each study group The CCC values were compared between the study groups using a z-test Power calculations determined a total sample size of 110 participants was needed to detect significant differences between the groups with at least 94 statistical power
