Abstract
Oral pentosan polysulfate is the only FDA-approved drug for interstitial cystitis. Several studies have
been conducted that show PPS will reduce IC symptoms. Sacral neuromodulation is a newer therapy for IC that has been FDAapproved
in incontinent patients. Both therapies have studies documenting a reduction in IC symptoms, but no studies have
compared these therapies to see which is more effective. Methods: An evidence-based systematic literature review was
conducted using Pubmed, Medline, and Proquest nursing journals. Inclusion criteria were a peer-reviewed article, publish date of
1990 or later, level 1 or 2 evidence, were diagnosed with IC, and were only treated with either oral PPS or sacral
neuromodulation during the study. Exclusion criteria were multiple therapies for IC or a non-IC diagnosis. Results: Three PPS
studies fit all inclusion criteria. With successful treatment being defined as a 50% overall improvement in symptoms, studies had
a success rate of 26-32%. Four studies fit the criteria for sacral neuormodulation. In these studies 40-94% of the patients had a
50% improvement in one or more IC symptom. Conclusions: PPS and sacral neuromodulation have both been shown to reduce
IC symptoms. Sacral neuromodualtion has been shown to have a higher rate of symptom relief in IC patients. Based on level 2
evidence, a Grade B recommendation can be made for sacral neuromodulation. This evidence was limited by sacral
neuromodulation studies having only level 2 evidence, while PPS has level 1 evidence studies. More studies are needed for each
of these therapies.
