Abstract:
Objective To seek the predictive value of pudendal nerve function that need preventive anti-incontinence surgery at the same time following pelvic prolapse surgery in severe pelvic organ prolapse (POP) patients. Methods Seventy women completed this study from January 2014 to June 2015 in Fuzhou General Hospital of Nanjing Military Command, dividing into four groups: POP with or without coexisting occult stress urinary incontinence (OSUI) in preoperation, women with persistent stress urinary incontinence (SUI) in postoperation, women without SUI in postoperation. The pudendal nerve function in preoperation was measured by using Solar Urodynamic Neuro Module, including pudendal nerve terminal motor latency (PNTML), and amplitude. Results There were statistical significance on bilateral PNTML between POP coexisting OSUI group and only severe POP group [(2.62±0.23) versus (2.40±0.26) ms in right of PNTML, (2.55 ± 0.21) versus (2.37 ± 0.30) ms in left of PNTML; all P<0.05], but no statistical significance on bilateral amplitude (P>0.05). Compared de novo SUI group with POP group in postoperation, de novo SUI group′s right of PNTML was significantly increased [(2.74 ± 0.16) versus (2.47 ± 0.26) ms; P<0.05]; and the right of PNTML was extending 2.5 standard deviation at least compared with the health′s [(2.10±0.20) ms]. Conclusions The PNTML of pudendal nerve of POP coexisting OSUI is severe than only severe POP, the velocity of nerve conduction is slowing, and PNTML extension has a predictive value for postoperative urinary incontinence. When the right of PNTML of preoperative POP increased by at least 2.5 standard deviations than health′s, the risk of SUI postoperative strongly increased, and a anti-incontinence surgery at the same time following pelvic prolapse surgery should be adviced.
