Affective symptoms and quality of life in patients with voiding or storage dysfunction: Results before and after sacral neuromodulation: A prospective follow-up study

Aims: Sacral neuromodulation (SNM) is an effective treatment for patients with overactive bladder syndrome (OAB) or non-obstructive urinary retention (NOR). These lower urinary tract symptoms (LUTS) are the result of a functional urological cause but often coincide with psychological and/or psychiatric factors. It has been stated that there is an association between LUTS, depression and anxiety disorders. With this study we will investigate whether affective symptoms and quality of life (QoL) improve after successful SNM.

Methods: All patients eligible for SNM between March 2013 and March 2016, filled out the HADS (Hospital Anxiety and Depression Scale), SF-36 (Short Form-36) and either the International Consultation on Incontinence Modular Questionnaire (ICIQ) on Male/Female Lower Urinary Tract Symptoms (M/F-LUTS), or the OAB-q questionnaire, before and after the test procedure. Symptom improvement of ≥50% was considered as success. Results were analyzed by paired T-tests and the Wilcoxon signed-rank test.

Results: In total 95 patients were included. Mean age was 52.1 (SD 13.9). Fifty-six patients (59%) were implanted. Successful OAB patients reported a significant improvement in all domains of OAB-q, health change and affective symptoms. Successful NOR patients showed a significant improvement in voiding symptoms (P = 0.04) and health change (P = 0.03). However, they did not report significant improvement in affective symptoms.

Conclusion: QoL and affective symptoms can significantly improve in LUTS patients who are successfully treated with SNM. When divided per indication, a significant improvement in affective symptoms together with QoL was only reported in successful OAB patients and not in successfully treated NOR patients.
