**11. Voiding disorders**

Rajendra et al (2011) reported after a 3 year follow up, that 11 patients with TVT-O (2.6%) (11/419) were readmitted since 10 patients had voiding dysfunction, in 6 patients it was necessary to remove or cut the tape. Reich et al (2011) reported it in 108 patients in a follow up period of 102 months (range of 85-124). They did not find adverse effects of the mesh; 90% of these patients presented urgency incontinence and were dissatisfied with the surgical procedure. The same group studied 478 with TVT and voiding dysfunction, documenting it by measuring residual volume pre and post surgery; they reported micturition dysfunction in the first 2 weeks in 4 patients (0.8%), 7.1% had a residual volume of 50-100 ml at 3 months of surgery and 2.6% had a residual urine volume of over 100 ml. Therefore, a total of 93% of patients did not show bladder voiding disorders after a follow up of 12 to 74 months, which was documented through translabial ultrasound. Alvárez-Bandrés et al (2010) reported that the Miniarc group had urethral obstruction and thus the mesh had to be cut.
