[Urinary incontinence after radical prostatectomy. Neurophysiological and urodynamic diagnosis]. L’incontinenza urinaria dopo prostatectomia radicale. Diagnosi urodinamica e neurofisiologica. OBJECTIVES: Urinary incontinence after radical prostatectomy presents different clinical features. We propose to clarify the etiology and the therapeutic approaches. METHODS: 51 patients with urinary incontinence after radical prostatectomy underwent urodynamics, perineal EMG, perineal EMG frequency analysis and study of computerized sensory pudendal somatosensory evoked potentials. RESULTS: 18 patients (35%) were suffering from urinary incontinence secondary to overactive bladder, 14 patients (28%) had both an overactive bladder and a sphincter failure associated with Wallerian degenerative axonal neuropathy or segmental demyelination, 3 patients (6%) showed no significant urodynamics alterations but had signs of an incompetent sphincter neurapraxia, while 16 patients (31%) had urinary incontinence secondary to a degenerative neuropathy. CONCLUSIONS: Urinary incontinence after radical prostatectomy shows an etiologic diversification and therefore requires different therapeutic approaches
