Brief Summary

The purpose of this study is to investigate the effect of Lidocaine solution versus placebo (isotonic Sodium Chloride NaCl) disposed inside the urinary bladder as intravesical anesthesia prior to onabotulinum toxin A injections in the treatment of urgency urinary incontinence.

Detailed Description

The aim of the study is to investigate if bladder installed Lidocaine solution have an effect on reported pain during BTX-A injections compared to placebo.

The study participants will be recruited from the existing patient populations enrolled in the BTX-A program of the tertiary Urogynaecological Clinic of Herlev University Hospital.

The participants are randomized to:

1. Active drug: Lidocaine Hydrochloride and Sodium hydrogen carbonate

2. Placebo: Sodium Chloride

The study includes 5 study visits:

Visit 1:

* First treatment day

* Randomization

* Registration of pre-treatment pain relief medications: paracetamol, ibuprofen, or other medications. If pre-treatment pain relief is taken before first treatment, same pain relief should be taken before second treatment day (visit 4) in order to reduce bias

* Registration of antibiotic treatment: current antibiotic treatment or long-term prophylactic antibiotic for prevention of recurrent UTI The participant receives the active treatment or placebo, double-blinded

* The participant is asked to grade the intensity of pain according to VAS score immediately after, and when participant has been dressed after the BTX-A injections

Visit 2 (by telephone):

* Phone consultation 1 week after treatment:

* The participant's experience on the procedure on a 5-point ordinal scale: "1- very unsatisfied", "2- unsatisfied", "3- neither unsatisfied or satisfied", "4- satisfied", "5-very satisfied"

Side effects:

* Questions on symptoms of UTI: dysuria, cloudy urine, pollakiuria, nocturia

* Hematuria

* Inability to empty the bladder

* Other symptoms

(Visit 3:)

* The participant contacts the Clinic for next treatment approximately 6-12 months later

* Sponsor or investigator from the Urogynecological Clinic reach out for the participant asking on symptoms of UUI if the participant has not contacted the clinic within 12 months

Visit 4:

* Second treatment day

* The participant receives the opposite treatment, still double-blinded

* Registration of pre-treatment pain relief medications: paracetamol, ibuprofen, or other medications

* Registration of antibiotic treatment: current antibiotic treatment or long-term prophylactic antibiotic for prevention of recurrent UTI

* The participant is asked to grade the intensity of pain according to VAS score immediately after, and when participant has been dressed after the BTX-A injections

Visit 5(by telephone):

* Phone consultation 1 week after treatment:

* The participant's experience on the procedure on a 5-point scale: "1- very unsatisfied", "2- unsatisfied", "3- neither unsatisfied or satisfied", "4- satisfied", "5-very satisfied"

Side effects:

* Questions on symptoms of UTI: dysuria, cloudy urine, pollakiuria nocturia,

* Hematuria

* Inability to empty the bladder

* Other symptoms

Alkalinized Lidocaine, then PlaceboAlkalinized LidocaineParticipants will have Lidocaine Hydrochloride 20 mg/ml, 20 ml and Sodium hydrogen carbonate 1 mmol/ml, 10 ml (ie a total of 30 ml) installed in the bladder for 15 minutes prior to the BTXA-injection procedure. When signing up for the next BTXA-injection with a wash out period of minimum three months, participants will have the matching placebo containing Sodium Chloride 9 g/L, 20 ml and Sodium Chloride 9 g/L, 10 ml, a total of 30 ml installed in the bladder for 15 minutes prior to the BTXA-injection procedure.

Primary Outcome Measures
NameTimeMethod
100 mm Visual Analogue Scale (VAS) scoreThe participant is handed the VAS in paper form and asked to grade the intensity of pain according to the VAS by making a handwritten mark on the VAS immediately after the BTX-A injections

The participant is contacted after each treatment and asked about any inability to empty the bladder

Urinary tract infection (UTI)Phone consultation one week after each treatment

The participant is contacted after each treatment and asked about symptoms of UTI: Dysuria, cloudy urine, pollakiuria, nocturia

HematuriaPhone consultation one week after each treatment

The participant is contacted after each treatment and asked about blood in the urine

5-point rating scalePhone consultation one week after each treatment
