Further experience with intravesical dimethyl sulfoxide in the treatment of interstitial cystitis.

Intravesical dimethyl sylfoxide has given satisfactory symptomatic relief in 75 per cent of patients with interstitial cystitis so treated. The treatment is simple and inexpensive, and can be safely administered as an office procedure. Objective improvement in the endoscopic appearance of the disease, with improvement in bladder capacity, was noted in 80 per cent of the patients in our series. Further work with dimethyl sulfoxide is indicated in the treatment of interstitial cystitis, as well as a variety of other genitourinary disorders.
