Resiniferatoxin was not associated with sustained differences in the review outcomes reported but pain during instillation and withdrawal from treatment was significantly more common .
Groups treated with BCG tended to report less pain and fewer general symptoms .
Although adverse events were commonly reported , these were no more common after BCG than after placebo instillation .
The few data about Pentosanpolysulphate tended to favour the actively treated , but with wide confidence intervals ; there was little information about adverse events .
Oxybutinin instillation was associated with increased bladder capacity , reduced frequency , improved quality of life scores and fewer drop-outs .
Alkalinisation of urine pH did not make any clear difference , but with potentially wide confidence intervals .
BCG and oxybutin are reasonably well-tolerated and evidence is most promising for these .
Resiniferatoxin showed no evidence of effect for most outcomes and caused pain , which reduced treatment compliance .
There is little evidence for the other treatments included in this review .
BACKGROUND Painful Bladder Syndrome/Interstitial Cystitis ( PBS/IC ) occurs predominantly in women .
It is a poorly-understood condition with symptoms of bladder pain , urinary frequency , urgency and nocturia .
Treatments for PBS/IC include dietary/lifestyle interventions , oral medication , intravesical instillations and , in some cases , surgery .
Success rates are generally modest and there is little consensus as to the best form of treatment for this condition .
OBJECTIVES To assess the effectiveness of intravesical treatment for PBS/IC .
A controlled study of dimethyl sulfoxide in interstitial cystitis.
To evaluate the effectiveness of dimethyl sulfoxide in the treatment of patients with biopsies suggestive of interstitial cystitis , 33 patients underwent a controlled crossover trial . Patients were allocated r and omly to receive 50 per cent dimethyl sulfoxide or placebo ( saline ) . The medication was administered intravesically every 2 weeks for 2 sessions of 4 treatments each . Response was assessed urodynamically and symptomatically . Thirty women and 3 men ( mean age 48 years and mean duration of symptoms 5.5 years ) were entered into the study . No significant side effects to dimethyl sulfoxide were noted . When assessed subjectively , 53 per cent of dimethyl sulfoxide treated patients were markedly improved compared to 18 per cent of the placebo treated patients . Of the dimethyl sulfoxide group 93 per cent had objective improvement versus 35 per cent of the placebo group . Thus , dimethyl sulfoxide proved to be superior to placebo in the objective and subjective improvement of patients with interstitial cystitis
