The aim of this study was to investigate changes in pudendal nerve terminal motor latency (PNTML) time in women with genuine stress incontinence (GSI) and with or without prolapse, in conjunction with measurement of maximal urethral closure pressure (MUCP). Eighty-five patients participated in the study and they were allocated to one of four groups, including the control group. A statistically significant difference was found in the PNTML time between patients with GSI and patients of the control group. The conduction time in patients with prolapse but no GSI did not show a statistically significant difference compared to the patients of the control group. The MUCP was reduced in patients with GSI, but no cutoff value of MUCP, which is pathognomonic of GSI, could be identified. We conclude that GSI is associated with a prolongation of PNTML time and a reduction in MUCP.
