Tension-free vaginal tape (TVT) is similarly effective for treating stress urinary incontinence in women with and without intrinsic sphincter deficiency, a South Korean study found.
Investigators at Yonsei University College of Medicine in Seoul studied the efficacy of TVT in both types of patients. The study population included 111 women—31 with intrinsic sphincter de-ficiency (ISD) and 80 with non-intrinsic sphincter deficiency (NISD). The two groups (mean age 60.7 and 57.2 years) did not differ significantly with respect to BMI (24.22 and 24.18 kg/m2), parity (3.55 and 3.03), menopausal status (87.1% and 70.0%), and use of hormone replacement therapy (20.69% and 21.25%).
One month after the TVT procedure, the cure rate was 87% in the ISD group and 100% in the NISD group, a significant between-group dif-ference. No significant differences were observed at three, six, and 12 months, however. At 12 months, the cure rates were 74% and 84%, respectively.
At one month post-procedure, voiding difficulty—which is the most common postoperative
complication—occurred in seven ISD patients (23%) and five patients in the NISD group (19%), according to researchers. At 12 months, the complication developed in two (6%) and four (5%) patients, respectively.
