Transurethral Resection Alone Vs Resection Combined With Therapeutic Hydrodistention as Treatment for Ulcerative Interstitial Cystitis: Initial Experience With Propensity Score Matching Studies.

OBJECTIVE

To compare the therapeutic efficacy of transurethral resection (TUR) alone with that of TUR combined with therapeutic hydrodistention in patients with ulcerative interstitial cystitis (IC).

METHODS

The study subjects were 44 female patients newly diagnosed with IC who underwent TUR to treat ulcerative IC and who were available for follow-up, without recurrence of disease for 12 months. We retrospectively studied both patients who underwent TUR alone (group I) and those who underwent TUR combined with therapeutic hydrodistention (group II). Improvements in pain and voiding symptoms were retrospectively evaluated using a 10-point visual analog scale for pain and a 3-day micturition chart.

RESULTS

Group I included 22 patients and group II included 22 patients of mean ages 58.45 ± 11.01 and 56.27 ± 11.86 years, respectively. Use of a 10-point visual analog scale showed that pain decreased after the procedures in both groups, but the improvement did not differ between groups. The maximum functional bladder capacities of patients in group I were 161.36, 192.47, and 204.12 mL, respectively, before, at 6 months, and at 12 months after the operation; the maximum functional bladder capacities of patients in group II were 175.45, 263.14, and 291.17 mL, respectively. The voiding frequencies of group I were 12.59, 10.67, and 9.89 times daily, respectively, before, at 6 months, and at 12 months after the operation; the voiding frequencies of group II were 12.95, 9.5, and 8.29 times daily, respectively.

CONCLUSION

TUR combined with therapeutic hydrodistention increased bladder capacity and improved voiding symptoms more so than did TUR alone for ulcerative IC.
