Convergent Validity of Stamey's Incontinence Scoring System in Assessing Post-Prostatectomy Urinary Incontinence

Area of Science:

• Urology
• Medical Assessment Tools
• Post-Surgical Recovery

Background:

• Post-prostatectomy incontinence is a common complication affecting quality of life.
• Accurate and efficient assessment tools are crucial for monitoring recovery and guiding treatment.
• Stamey's Incontinence Scoring System offers a simplified approach to evaluating incontinence severity.

Purpose of the Study:

• To evaluate the convergent validity of Stamey's Incontinence Scoring System.
• To compare its performance against daily pad use in assessing post-prostatectomy incontinence.
• To determine its reliability at various time points after radical prostatectomy.

Main Methods:

• Retrospective analysis of 295 patients post-radical prostatectomy.
• Collected data on Stamey's Grade, ICI-Q-SF, and daily pad use at 1.5, 3, 6, and 12 months.
• Utilized Spearman's rank correlation and Quadratic weighted Kappa for statistical analysis.

Main Results:

• Stamey's system demonstrated strong positive correlations with ICI-Q-SF (P<0.001).
• Significantly higher agreement with ICI-Q-SF compared to daily pad use (P<0.001).
• Early severity grade correlated with subsequent patient recovery trends.

Conclusions:

• Stamey's grade exhibits superior consistency and a simpler structure than existing tools.
• It offers a more efficient method for follow-up of patients after radical prostatectomy.
• The system aids in reducing clinical workload and improving patient management.
