**7.1 Immediate post-surgical complications**

#### **7.1.1 Hematomas**

Abouassaly et al (2004) reported a pelvic hematoma in 4 (1.9%) patients with TVT (4/421), Andonian et al (2005) reported a single case of an infected pelvic hematoma in the SPARC group and none in the TVT group. Pushky et al (2011) found that the formation of a hematoma is more frequent with TVT than with TVT-O (9.1% vs. 1.5%; p=0.001). Flock et al (2011) reported successful treatment of hematomas with retziusscopy in patients with TVT, of 685 patients, only 28 (4.1%) had a symptomatic hematoma in the Retzius space and in only 10 cases (1.5%) the volume exceeded 250 ml (range of 250-1000ml), the first case was resolved through laparotomy but the other cases were resolved successfully with a drainage through a retziusopy; this is a minimally invasive procedure. Latthe et al (2010) in a systematic review of 12 papers observed that the formation of hematomas is lower with the TOT procedure compared with the TVT with an OR of 0.06 (IC 95% 0.01-0.30). When Alvárez-Bandrés et al (2010) compared TVT –secur and Miniarc; they reported one case of hematoma of the obturator fossa (0.64%) in the Miniarc group, which resolved spontaneously.
