**10. Late complications**

### **10.1 De novo urgency**

Abouassaly et al (2004) reported de novo urgency in 36 patients (15%), Lleberia-Juanós et al (2011) determined the incidence of de novo urgency with VT (in 243 patients) and with TVT-O (123 patients) evaluating them at 1, 6, 12 and 36 months after surgery. De novo urgency occurs in 13.4% of patients at 6 months, in 19.3 at 12 months and in 22.1% at 36 months. De novo urgency was more frequent in the TVT group than in the TVT-O group at 12 months (22.2% vs. 11.2%, P=0.025) and at 24 months (24.8% vs. 12.3%, P=0.033). Lee et al (2010) after 6 years of observation reported that de novo urgency was present in 28% (30/107) and de novo overactive bladder with incontinence was present in 27.1% (29/107) of patients. Sun and Tsai (2011) reported a frequency of de novo urgency of 2.7% with MONARC (2/73). Sabadell et al (2011) reported that 23 patients failed to TOT and a TVT was placed in a second surgery; de novo urgency occurs in 5 cases (21.7%) and it is treated with oral anticholinergics with a good clinical response.
