Abstract

AIMS: Extracorporeal shock wave therapy (ESWT) inhibited bladder inflammation and pain in preclinical studies. We assessed ESWT for the treatment of refractory interstitial cystitis/bladder pain syndrome (IC/BPS).

METHODS: This double-blind, randomized, placebo-controlled physician-initiated study enrolled 54 patients with IC/BPS. The patients were assigned to ESWT (N = 24; 2000 shocks, frequency of 3 Hz, and maximum total energy flow density 0.25 mJ/mm

RESULTS: At 4 weeks posttreatment, both groups were associated with a statistically significant decrease in OSS and VAS pain scale. However, there were no difference in mean change between ESWT vs placebo groups. A significantly higher proportion of patients on ESWT responded as improved in the VAS ≥ 3 vs placebo (P = .035). At 12 weeks posttreatment, improvement in the VAS ≥ 3 was 57.1% vs 19.0% (ESWT vs placebo; P = .011). The finding was associated with an improvement in frequency - 1.0 ± 2.3 vs 0.7 ± 3.2 (ESWT vs placebo; P = .065). No significant adverse events were found in either group.

CONCLUSIONS: A reduction in pain was discovered in this trial assessing ESWT in patients with IC/BPS but OSS, which was the primary outcome parameter, was not improved.
