AMS AdVance and AdVance XP Male Sling Systems for the Treatment of Stress Urinary Incontinence Following Prostatectomy: Evaluation of Safety, Efficacy, and Quality of Life Through Retrospective Chart Review and Prospective Follow-up

American Medical Systems80 enrolled

Overview

A single-center retrospective chart review of AdVance and AdVance XP subject data, combined with prospective follow-up of the same subjects to confirm continence, adverse event, and quality of life status. This study includes patients previously implanted with an AdVance or AdVance XP male sling.

Treatment with a urethral sling system, an AMS Sphincter 800®, or any implanted device for the treatment of urinary incontinence (not including bulking agents) prior to sling placement 4. TURP procedure prior to sling placement 5. Urge predominant incontinence prior to sling placement 6. Past or current neurological disorder (e.g. neurogenic bladder, multiple sclerosis, Parkinson's disease) 7. History of connective tissue or autoimmune conditions 8.

Outcomes

Primary Outcomes

Percentage of Subjects With a ≥50% Reduction in Pads Per Day Use

Evaluate the proportion of subjects with a ≥50% reduction in pads per day use

Time frame: 3 Months Post Procedure

Percentage of Subjects Cured, Improved, or Failed Based on Reported Pad Per Day Use

Evaluate the proportion of subjects cured (0 pads per day or 1 dry prophylactic pad), improved (not cured and ≥50% reduction in pad use), or failed (not cured and not improved) at the three month and final prospective follow-up visit

Time frame: 3 months Post Procedure

Percentage of Subjects in Each Pre-defined Range of Pads Per Day Use

Evaluate the proportion of subjects using the following categories of pads per day at the three month and final prospective follow-up visit: 0 pads per day or 1 dry prophylactic pad; 1 pad per day; 2 pads per day; 3 pads per day; 4 pads per day; 5 or more pads per day (5, 6, 7, 8 etc. pads per day);

Time frame: Baseline

Evaluate the 24-hour Pad Weight at the Final Prospective Follow-up Visit

Percentage of subjects at a given weight for their 24-hour pad weight test at the final prospective follow-up visit.

Time frame: Prospective follow-up to 36 Months Post Procedure

Change in Quality of Life Scores as Compared to Baseline for I-QOL, ICIQ-SF, and Summary of Values for the PGI-I. Measured From Baseline to Prospective Follow.

The Incontinence Quality of Life Questionnaire (I-QOL) is a 22 questionnaire that evaluates a subject's quality of life with respect to urinary problems/incontinence. A lower score correlates with more severe incontinence, and an increase from baseline indicates an improvement in quality of life. The score scale is 0 - 100. The International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) is a 4 question tool that quantifies the impact on quality of life from incontinence. A decrease from baseline to follow-up indicates an improvement in quality of life. The score scale is 1-21. The Patient Global Impression of Improvement (PGI-I) questionnaire is a single question instrument that assess a subject's perception of the disease impact on their quality of life. Completed at the last visit, a lower score indicates a better perception from the patient. Scale from 1 to 7.

Time frame: Baseline to Prospective Follow Up (up to 36 months)

Number of Adverse Events Reported Between Arms

Evaluate the occurrence of all AdVance /AdVance XP AEs, as well as those reported as serious, intra-operative, device or procedure related adverse events

Time frame: Prospective follow-up to 36 Months Post Procedure

Percentage of Subjects With a ≥50% Reduction in Pads Per Day Use

Evaluate the proportion of subjects with a ≥50% reduction in pads per day use

Time frame: Prospective follow-up to 36 Months Post Procedure

Percentage of Subjects Cured, Improved, or Failed Based on Reported Pad Per Day Use
