Digital Mapping of the Urinary Bladder: Potential for Standardized Cystoscopy Reports

Area of Science:

• Urology
• Medical Imaging
• Digital Health

Background:

• Cystoscopy is a crucial diagnostic procedure for evaluating the urinary bladder.
• Standardized reporting of cystoscopy findings can be challenging, potentially leading to interobserver variability.

Purpose of the Study:

• To develop and evaluate a novel digital reporting tool for urinary bladder cystoscopy using panoramic imaging.
• The goal is to standardize cystoscopy documentation and improve the visualization of bladder anatomy and pathology.

Main Methods:

• Development of image processing and stitching software (Endorama) to generate panoramic images from cystoscopy data.
• Refinement of algorithms using 30 cystoscopy sequences.
• Application of the software to record panoramic images from 12 patients undergoing transurethral resection of bladder tumors.

Main Results:

• The Endorama software successfully generated high-quality panoramic images in 10 out of 12 cases.
• Images had a resolution of 4096×2048 pixels and a median digital memory of 3.9 MB.
• The panoramic images effectively illustrated 22 relevant findings, including 7 papillary tumors, and showed the endoscope's pathway.

Conclusions:

• High-quality digital panoramic maps of the urinary bladder can be created from videocystoscopy data.
• This tool demonstrates potential for improving the standardization of cystoscopy reports.
• The developed panoramic imaging approach may help reduce interobserver variability in cystoscopy assessments.
