He has fecal incontinence so his external sphincter is damaged, which is innervated by the pudendal n. (S2-S4). The pelvic splanchnic nerves, which mediate the erection process, are also S2-S4.
thomasburtonWhy could this not be dysuria?+2019-09-17T12:02:47Z
lilyoI think that you are thinking about urinary incontinence. If we damage the pudendal nerve S2-S4, you can exhibit urinary and fecal incontinence since this nerve innervates both the urethral and the external anal sphincters. However since the pelvic splanchnic nerves also have roots that originate in S2-S4 a patient with pudendal nerve damage will also have impotence since these control the erection reflex. He wouldn't have dysuria which is painful urination. Most likely caused by a urethral infection or a blockade of the urinary tract. He would have urinary incontinence. I hope this helps. +82019-09-26T16:39:55Z
alexxxx30dysuria is painful urination...if it said urinary incontinence then you'd be right. But decreased innervation wouldn't cause pain (that would mores be associated with UTI)+2020-02-18T20:47:14Z
