**8. Voiding disorders**

Abouassaly et al (2004) reported urinary retention (>24 hours later) in 47 patients (19.7%). Of the 47 patients, retention was present in only 32 less than 48 hours later, which were managed with clean intermittent catheterization, the remaining 15 patients also had clean intermittent catheterization for several days and only one patient had catheterization for 22 days. In order to resolve retention in 7 patients, the mesh had to be released and in 3 patients the mesh had to be cut. Kristensen et al (2010) reported difficulty in voiding in 56% and 16.6% had urinary retention, 34.3% of the patients had catheterization and 8% needed continuous catheterization. They conclude that patients who had voiding dysfunction prior to surgery have an OR of 1.80 to present urinary retention post surgically. Lee et al (2010) reported that 10 patients with TVT surgery, (7.1%) had urinary retention after surgery; patients were treated with clean intermittent catheterization less than 1 week, 10 patients (7.1%) needed continuous catheterization and in 2 patients the TVT mesh had to be cut. George et al (2010) reported voiding difficulty with a follow up of 2 years; in the TVT group 9.3% it lasted less than one week and in 2.6% it lasted more than one week. In the TOT group, the voiding dysfunction was 4.1% less than 1 week and 1.4% more than 1 week. Bladder perforation has a higher incidence in the TVT group. Revicky et al (2011) reported urinary retention in 9% (31/342). Sun and Tsai (2011) reported a voiding dysfunction frequency of 6.8% with MONARC (5/73). Latthe et al (2010) in a systematic review of voiding disorder it is slightly lower in the TOT group than in the TVT-O group, but it wasn't statistically significant; for TOT the OR was 0.61 (IC 95% 0.35-1.07) and for TVT-O the OR was 0.81 (IC 95% 0.48-1.31
