Abstract
IntroductionDetrusor underactivity (DU) is currently a topic that receives major attention within functional urology. Urologists are often confronted with men who present with voiding dysfunction without bladder outlet obstruction (BOO) or after desobstructive or neuromodulation treatment. Their impaired bladder emptying is suspected to be related to failure of detrusor contractile function. Earlier research indicated that patients with non-obstructive urinary retention (NOR), for example, detrusor underactivity (DU), have a lower success rate after sacral neuromodulation (SNM) compared to patients treated with SNM for storage dysfunction. However, predicting factors for treatment success in the NOR group have not yet been defined.
Methods and EvidenceThe aim of this study was to assess whether the use of the new BOO-contractility (Maastricht-Hannover) nomogram can identify and predict SNM non-responders. Our results in 18 men showed that only 20% of patients below the 10th percentile, but 86% of men between the 10 and 25th percentiles of the nomogram can be treated successfully with SNM. All successfully treated patients voided without needing self- catheterisation.
ConclusionsThis pilot study showed for the first time that SNM treatment response in male patients with impaired bladder emptying can be predicted with the BOO-contractility (Maastricht-Hannover) nomogram. Men below the 10th percentile are likely to be treatment non-responders, whereas the majority of men above the 10th percentile are responders. Neurourol. Urodynam. 36:808-810, 2017.
