Based on the results of a controlled trial with a 2-year follow-up (n = 50), Meschia and colleagues (2004) stated that TVT can be recommended for patients with prolapse and occult SUI. In a comparison study (n = 61), deTayrac and co-workers (2004) concluded that transobturator suburethral tape appears to be equally efficient as TVT for surgical treatment of SUI in women, with no reduction of bladder outlet obstruction at 1-year follow-up.
