What Are Pudendal Nerve Latency Testing Results?
In the treatment of fecal incontinence, pudendal nerve latency testing is ineffective.
This test is commonly used to determine whether a patient has urinary incontinence because of pudendal nerve terminal motor latency (PNTML). It has been questioned in the past whether it can help guide fecal incontinence therapy. The study's goal was to see if there was any connection between anorectal dysfunction and PNTML testing.
Patients who visited a pelvic floor problem clinic between 2007 and 2015 were included in this study's retrospective examination of data. The Wilcoxon-Mann-Whitney test was used to examine the correlation between PNTML (normal versus delayed) and anorectal manometry, fecal incontinence severity, and fecal incontinence-related quality of life.
A total of 245 individuals received PNTML testing, with 91.1% of them being female (median age 62.2 years). In 234 individuals, the PNTML was found to be normal in 87% of the cases. Only the median maximal anal squeezing pressure (P =0.04) was significantly linked with delayed PNTML in 268 individuals who underwent anorectal manometry. There was no correlation between delayed PNTML and decreased median fecal incontinence severity or quality of life scores (N = 99).
As a result of these findings, PNTML was only linked with median maximum anal squeeze pressure, and was not connected with patient-reported severity of fecal incontinence symptoms, changes to quality of life attributed to fecal incontinence, or the median mean resting anal pressure. For fecal incontinence, PNTML testing may not be meaningful and should be reconsidered in ordinary practice.
