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

Anatomy of the Genitourinary System II: Bladder and Urethra
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
