Area of Science:

  • Urology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Urodynamic examination is crucial for diagnosing lower urinary tract dysfunction.
  • Quality control is essential to standardize urodynamic procedures and ensure clinical reliability.

Purpose of the Study:

  • To develop and evaluate a deep learning (DL) algorithm for recognizing typical urodynamic signals.
  • To assist physicians in performing high-quality urodynamic examinations.

Main Methods:

  • A DL model (Yolov5l) was trained and validated using 1,960 urodynamic images from 300 neurogenic bladder patients.
  • The model's performance was tested on an independent cohort of 695 images from 100 neurogenic bladder patients.

Main Results:

  • The Yolov5l model achieved strong performance with an F1 score of 0.81 and mean average precision of 0.83.
  • The study was a retrospective single-center analysis, and model generalizability requires further verification.

Conclusions:

  • Deep learning algorithms show potential for real-time identification of urodynamic signals.
  • These algorithms can enhance the interpretation and quality of urodynamic examinations, ultimately benefiting patient care.
