In order to provide a device of this type, by means of which the integrity/correct functioning of nerves acting on one or more pelvic organs, i.e. in particular the bladder and/or rectum, can be reliably monitored during surgery of the pelvic region of a patient without significant delay, according to the invention the sensor device (20) has at least two measuring electrodes (23) which can be applied to the pelvic organs (14; 15) and an impedance measuring device (21) which is connected or can be connected to the measuring electrodes and has a display (22) which indicates the change in impedance at the pelvic organs (14; 15) between the measuring electrodes (23). Stimulation of nerves connected to pelvic organs such as the bladder or rectum results in changes in complex electrical resistance (impedance) within the tissues of the relevant organ, which can be used as an indicator of the integrity of the nerves stimulated by the neurostimulator.)
