[Elektronische Daten] [Claudia Hacad, Howard Glazer, João Zambon, Juliana Burti, Fernando Almeida] The aim of this study is to determine electromyographic pelvic floor muscles activity during the first 6months post RRP and its relationship to urinary continence. Thirty-eight men (mean age of 63.1±5.7year) with prostate cancer scheduled for open radical retropubic prostatectomy were evaluated. Exclusion criteria: pelvic radiotherapy, systemic or neurologic diseases, pre-operative International Prostate Symptoms Score (IPSS) >7 and OABq ≥8. Surface electromyography (sEMG) evaluation, IPSS, Urinary Distress Inventory, Incontinence Impact Questionnaire, and Overactive Bladder Questionnaire—short form were applied before and at 1, 3, and 6months after RRP. Six months after surgery, 18 men (47.4%) presented urinary leakage. The sEMG evaluations within the first 6months presented changes in fast contraction amplitude (p=0.006), rest amplitude after fast contraction (p=0.04), 10s sustained contraction mean amplitude (p=0.024) and final rest amplitude (p=0.011). We observed that continent and incontinent patients as a group presented electromyographic changes during the first 6months after radical prostatectomy that could be justified by the denervation/reinnervation of the external urethral sphincter. This finding is consistent with the adaptation of the pelvic floor musculature to the new urethral sphincter condition following surgery.
