Abstract

Objective: To develop a quantitative hematuria scale that assigns specific blood concentration percentages to commonly used descriptors such as "clear," "mild," "moderate," and "severe," in order to standardize hematuria severity assessments during Continuous Bladder Irrigation (CBI) and reduce reliance on subjective visual evaluations.

Methods: Samples of bovine blood with concentrations ranging from 0% to 100% were created, photographed, and distributed to a cohort of urologists and healthcare workers in a survey. Respondents were asked to categorize these samples as clear, mild, moderate, or severe. Fleiss' kappa analysis was performed to evaluate inter-rater agreement.

Results: Data from 39 respondents were analyzed, and consensus categories for each blood concentration were determined using mode and weighted averages. Overall agreement among respondents was moderate (Kappa=0.53, p < 0.0001). The categories "clear" and "severe" demonstrated substantial agreement (Kappa=0.63), while "moderate" and "mild" showed moderate and fair agreement, respectively.

Conclusions: This study presents a promising foundation to a novel quantitative scale for hematuria assessment, reducing reliance on subjective visual judgments. The scale would enable clearer and more consistent communication of hematuria severity, which is crucial as urological technologies advance toward quantitative measurements.

期刊介绍： Urology is a monthly, peer–reviewed journal primarily for urologists, residents, interns, nephrologists, and other specialists interested in urology The mission of Urology®, the "Gold Journal," is to provide practical, timely, and relevant clinical and basic science information to physicians and researchers practicing the art of urology worldwide. Urology® publishes original articles relating to adult and pediatric clinical urology as well as to clinical and basic science research. Topics in Urology® include pediatrics, surgical oncology, radiology, pathology, erectile dysfunction, infertility, incontinence, transplantation, endourology, andrology, female urology, reconstructive surgery, and medical oncology, as well as relevant basic science issues. Special features include rapid communication of important timely issues, surgeon''s workshops, interesting case reports, surgical techniques, clinical and basic science review articles, guest editorials, letters to the editor, book reviews, and historical articles in urology.
