“…To our knowledge, although AUM-related morbidity has been mentioned in several studies [6], preprocedural patient perceptions or post-procedural experiences have not previously been addressed. Anxiety or a high level of concern can affect a patient's attitude towards AUM.…”

“…There were no complications in the small case number, and although statistical analysis therefore cannot be forwarded, the nature of the method is very unlikely to produce any significant compromise of the patients' health. An investigation on the morbidity of ambulatory urodynamics showed a 1.1% chance of developing a positive urinary culture [2].…”

IntroductionThe use of urodynamics in spinal operations is an established method in neurosurgery, in particular for the denervation of spastic reflex bladders [6,13,14] or for the implantation of bladder stimulators to support bladder contraction in paraplegics [4,5,6,13]. Despite these applications, the use of urodynamics in IOM is not practised routinely and only few publications on this subject are found [5,12,15]. Routine use of somatosensory evoked potentials (SEP) or continuous EMG recordings are a standard in most neurosurgical units [3,8,10,11]. Our intention was to evaluate the use of urodynamics in spinal cord surgery and to determine indications, possible applications and limitations of this method. Monitoring of bladder function focuses mainly on the preservation of continence and voiding. The control of urinary continence by continuous EMG recording of the external anal sphincter is a well-established method in neurosurgery [1,7,9]. According to James et al. [7] muscle action potentials of the external anal sphincter reflects the function of the external urethral sphincter as both are innervated by the pudendal nerve from the S2-S4 segments.Monitoring of voiding ability is less straightforward than EMG recording due to bladder function being controlled Abstract Intraoperative monitoring (IOM) of bladder function in spinal cord surgery is a challenging task due to vegetative influences, multilevel innervation and numerous supraspinal modulating factors. Despite routine use of urodynamics in neurosurgery for implantation of bladder stimulators or denervation of nerve fibres in spastic reflex bladders, application of IOM in patients with spinal cord tumours or tetheredcord syndrome is not widespread. Combining urodynamics with sphincter electromyography (EMG) in IOM enables identification of bladder efferents responsible for contraction and continence. We monitored four patients with ependymoma of the Cauda equina, one patient with tethered-cord syndrome and two patients with cervical intramedullary tumours. In all patients undergoing operations of the Cauda equina, identification of bladder efferents responsible for detrusor contraction was possible. There was good correlation between preoperative bladder dysfunction, preoperative urodynamics and intraoperative pressure increase by bladder contraction or latency between stimulation and contraction. This method proved unsuitable for intramedullary tumours where no contraction of the bladder could be observed while stimulating the spinal cord. Intraoperative monitoring of urodynamics is an effective tool for identifying bladder efferents in the Cauda equina. Intraoperative conclusions on bladder dysfunction through registration of pressure increase and latency are possible.

“…BWT was measured by TV ultrasound (>5 MHz probe), in three places: (1) perpendicular to the luminal surface of the bladder at the thickest part of the trigone, (2) at the dome of the bladder, and (30 at the anterior wall of the bladder, and the mean measurement was recorded . All measurements were taken post‐micturition and after ensuring that the patient had a residual of less than 50 mL.…”
