Optimizing Telemedicine Technologic Infrastructure with Animal Models: A Case in Telecystoscopy

Area of Science:

• Urology
• Telemedicine
• Medical Technology

Background:

• Telemedicine, particularly telecystoscopy, enables remote bladder examinations by advanced practice providers guided by off-site urologists.
• Rapid technological advancements necessitate frequent adaptation of telemedicine procedures and equipment.
• Previous work established the technological infrastructure for optimal video quality in telecystoscopy.

Purpose of the Study:

• To evaluate the diagnostic capabilities of different cystoscope and coder/decoder (codec) combinations.
• To compare the performance of Storz and Wolf cystoscopes with SX20 and DX70 codecs in a telemedicine setting.
• To determine the impact of newer versus older codec technology on diagnostic accuracy in telecystoscopy.

Main Methods:

• Flexible cystoscopy was performed on ex vivo porcine bladders using Storz and Wolf cystoscopes with SX20 and DX70 codecs.
• Eight distinct video recordings were created by varying cystoscope, codec, and internet transmission speed.
• Expert urologists reviewed deidentified videos via electronic survey, assessing video quality and diagnostic ability using logistic regression analysis.

Main Results:

• Sixteen urologists reviewed eight transmitted cystoscopy videos.
• The original combination of the Storz cystoscope and SX20 codec demonstrated the highest diagnostic capacity.
• This finding indicates that newer codec technology (DX70) did not outperform the older SX20 in this specific application.

Conclusions:

• Routine validation of telemedicine technical infrastructure is crucial to assess component impact on quality.
• Newer technology does not automatically guarantee improved performance in telemedicine procedures.
• Ex vivo animal models serve as valuable tools for testing and validating new components for telemedicine applications, especially if older components become obsolete.
