Current radical surgery against localized prostate cancer (PCa), such as open (Memmelaar, 1949; Reiner & Walsh, 1979; Walsh & Donker, 1982), laparoscopic (Schuessler et al., 1997; Abbou et al., 2000; Guillonneau et al., 2003) or robot-assisted prostatectomy (Binder & Kramer, 2001; Menon et al., 2002; Menon et al., 2004), has a possible risk to injure supporting structures that surround and support the prostate as well as the external sphincter and the neurovascular bundle. As a result, postoperative stress urinary incontinence develops and continues in about 10 % of patients (Stanford et al., 2000; Lepor et al., 2004; Namiki et al., 2009; Menon et al., 2007)
