Lee, Kim, Koh, Kim, Lee, Suh, Lee, and Lee: The Changes of Storage Symptoms after Tension-free Vaginal Tape Procedures in Stress Urinary Incontinence Patients

Abstract

Purpose

We evaluated the changes of storage symptoms after tension-free vaginal tape (TVT) procedures in stress urinary incontinence (SUI) patients, and we investigated the factors predicting the changes of storage symptoms.

Materials and Methods

From January 2000 to August 2003, 713 patients with SUI were operated on with using suburethral sling procedures (TVT). A follow-up study was conducted for over a one year period with 495 patients. We analyzed the one year outcomes of TVT surgeries and the changes of storage symptoms after TVT.

Results

The rates of cure and improvements at one year after TVT were 80.8% and 12.3%, respectively. At one month after TVT, 59 of 180 (33%) patients with urgency before TVT were improved, and 60 of 72 (83.6%) patients with urgency incontinence before TVT were improved. In 86 of 180 (47.8%) patients, the urgency is improved, and in 65 of 72 (90.1%) patients, the urgency incontinence disappeared at one year after TVT procedure. Urgency developed in 65 of the 243 (26.9%) patients who had no urgency before TVT, but after 1 year, only 28 (10.2%, 25/243) these 243 patients had urgency. 102 (31.6%) of the patients with frequency before TVT were improved after TVT. Of the 92 patients with nocturia, 22 (23.4%) patients were improved. There were no statically significant factors predicting the changes of the storage symptoms.

Conclusions

The total improvement rate (cure+improvements) of stress urinary incontinence was 93.1% at one year. We can expect the improvement of urgency (47.1%) and urgency incontinence (90.1%) after TVT procedures, but not improvement of the frequency and nocturia.
