“…[19] In a randomized, controlled study, Finazzi-Agro et al [17] reported that PTNS significantly increased voided volume than sham treatment (150-186 mL in the PTNS treatment group vs. 146-150 mL in the sham group, p<0.001). In a urodynamic study, Klingler et al [21] reported that PTNS increased the mean total bladder capacity from 197 mL at baseline (range 35-349 mL) to 252 mL (range 78-384 mL, p<0.01) after 12 weeks of therapy. When PTNS was compared with tolterodine extended release in the OrBIT study, both therapies demonstrated statistically significant improvements in incontinence episodes, voids per day, and nocturia.…”
