Correlation of lidocaine induced changes in bladder capacity , compliance and number of uninhibited contractions with improvement on oral oxybutynin was 70.6 % , 64.3 % and 66.7 % , respectively .
The effects of intravesical lidocaine on bladder dynamics of children with myelomeningocele. Other studies have suggested that intravesical lidocaine may temporarily improve bladder dynamics but details of these effects and their application to children have not been examined. We evaluated the effects of intravesical lidocaine on bladder urodynamics of children with myelomeningocele and tried to correlate these effects with subsequent clinical response to oral oxybutynin. ### Materials And Methods Charts of children with myelomeningocele who had undergone urodynamic examinations from 1992 to 1998 were reviewed retrospectively. In children with uninhibited contractions or poor compliance 150 to 300 mg. lidocaine were instilled for 8 minutes and cystometry was repeated. Changes in bladder capacity and compliance, number of uninhibited contractions and bladder volume at which pressure of 40 cm. H2O was reached were recorded before and after the lidocaine instillation. Clinical response to subsequent treatment with oral oxybutynin was assessed from chart review. ### results A total of 48 urodynamic studies in 22 girls and 20 boys with a mean age plus or minus standard deviation of 8.3 +/- 5.7 years and myelomeningocele were evaluable. After instillation of lidocaine, urodynamics showed increased bladder capacity in 70.8% of studies (34 of 48), with an average increase in volume of 66% (p <0.05). No change or decreased bladder capacity occurred in 29.2% of studies. Bladder compliance improved in 61.7% of the studies (29 of 47, p <0.05) and worsened in 38.3%. Bladder volume at which the pressure of 40 cm. H2O was reached increased in 77.8% of studies (14 of 18, p <0.05). After lidocaine the number of uninhibited contractions decreased by 3.2 in 56.8% of studies (21 of 37, p <0.05). Correlation of lidocaine induced changes in bladder capacity , compliance and number of uninhibited contractions with improvement on oral oxybutynin was 70.6 % , 64.3 % and 66.7 % , respectively . ### conclusions Intravesical lidocaine can improve bladder capacity and compliance and decrease the number of uninhibited contractions in many children with neurogenic bladder caused by myelomeningocele. These observations suggest that intravesical lidocaine has effects on the neurogenic bladder that improve bladder dynamics. Although intravesical lidocaine testing may not reliably predict clinical response to oral oxybutynin at the prescribed dosages, a possible therapeutic role for intravesical lidocaine or similar agents should be explored further.
