Abstract:
Objective To evaluated the clinical outcomes of intravesical instillation resiniferatoxin(RTX) for the treatment of patients with idiopathic overactive bladder(IOAB).Methods 26 cases with IOAB were randomly divided into test(A,14 cases) and control(B,12 cases) groups.The patients in group A were treated by intravesical instillation with 40ml of 0.5% idocain retained within the bladder for 3 minutes at first and with 100ml of 100nmol/L RTX retained within the bladder for 30 minutes late.The patients in group B were treated by the same method,however,the furacilin solution(placebo) at a dilution 1∶5000 was used instead of 100nmol/L RTX.The efficacy(daily voiding frequency,urgent uresis,FDV,MCBC,Qmax) of the 2 groups were evaluated before,1 month and 3 months after treatment.Results The pre-treatment comparion with prost-treatmen at 1 month and 3 months of A group was significant(P0.05).14 patients(54%) had slightly stimulating symptom in the urethra or bladder,and were otherwise generally well tolerated.Conclusion Single administration of RTX is safe and effective in patients with IOAB.
