Long-term functional outcomes of artificial urinary sphincter (AMS 800™) implantation in women aged over 75 years and suffering from stress urinary incontinence caused by intrinsic sphincter deficiency

PURPOSE

To assess the outcomes after artificial urinary sphincter (AUS) implantation in older women aged over 75 years.

METHODS

A monocentric retrospective study included all non-neurological women aged over 75 years suffering from stress urinary incontinence (SUI) due to intrinsic sphincter deficiency and undergoing an AUS placement between 1991 and 2015. Early postoperative complications were reported according to Clavien-Dindo classification. Continence, defined as no pad use, was assessed at the end of follow-up. Explantation, revision and deactivation rates of the AUS were reported. A Kaplan-Meier survival curve was generated to evaluate the survival rate of the device without revision or explantation.

RESULTS

Among 393 AUS implantations, a total of 45 patients, median age 77 years (IQR 75-79), were included. Twenty-six early postoperative complications occurred in 18 patients (40%) patients. All were minor Clavien grades (I-II) except one (grade IVa). Median follow-up was 36 months (IQR 16-96). Overall, 32 women (71.1%) still had their AUS in place at the end of the follow-up, without revision or explantation. The AUS was definitively removed in four (8.9%). The AUS required revisions in nine (20%) women. The 5- and 10-year survival rates of the device without revision or explantation were 78 and 50%, respectively. Three patients (6.7%) had their AUS deactivated. At last follow-up, in an intention-to-treat analysis, the continence rate was 68.9%.

CONCLUSION

In women aged over 75-years-old, suffering from SUI, the AUS provides satisfactory functional results comparable to the general population.

[Assessment of severity of neurogenic bowel dysfunction in chronic patients with a simple 1-item questionnaire (PGI-S)]

INTRODUCTION

Bowel symptoms (constipation and incontinence) are frequent in patients with a neurologic disease, but rarely assessed in rehabilitation centres.

AIM

To study the prevalence of neurogenic bowel dysfunction (NBD) in those patients, and to assess its severity with the Patient Global Impression of Severity (PGI-S).

MATERIAL

Prospective study by questionnaires, with the Neurogenic Bowel Dysfunction Score (0-47) and the PGI-S, a 1-item questionnaire (absent, mild, moderate, severe) for the severity of the bowel symptoms, and the Bristol Stool Chart for stool consistency. All patients presenting a chronic (>2months) neurological disease were included.

RESULTS

Inclusion of 169 patients, 97 with spinal cord injury, 42 with multiple sclerosis and 30 with hemiplegia. In each population, prevalence of constipation was 67 %, 45 % and 17 %, of pelvic floor dyssynergia 82 %, 45 % and 27 %, and leakages (gas or stools) de 74 %, 48 % and 43 %, respectively. Moderate to severe bowel symptoms were seen in 61 % of spinal cord injury, 43 % of multiple sclerosis and 23 % of hemiplegic patients, with NBD scores of 11.9±6.5, 5.7±4.9 and 3.7±4.2, respectively (P<0.01). There was a significant relation between PGI-S and NBD score (P<0.01). Significant lower NBD scores were associated with normal stool consistency (Bristol type 3 or 4) (P<0.01). In case of severe bowel symptoms, the use of transanal irrigation was hampered by patients' motivation and acceptation, and their autonomy.

CONCLUSION

PGI-S and Bristol Stool Chart are reliable tools to assess the presence of bowel symptoms in clinical practice.
