A new formula improves prostate volume estimation using abdominal ultrasound (AUS) before laser surgery for benign prostate hyperplasia (BPH). This validated method enhances surgical planning and reduces operating time, especially for larger prostates.

Area of Science:

  • Urology
  • Medical Imaging
  • Surgical Planning

Background:

  • Benign prostate hyperplasia (BPH) is a common condition requiring surgical intervention.
  • Accurate preoperative prostatic volume estimation is crucial for effective surgical planning in BPH treatment.
  • Abdominal ultrasound (AUS) is frequently used for prostatic volume assessment, but its accuracy can be limited.

Purpose of the Study:

  • To validate a novel formula for improving prostatic volume estimation using abdominal ultrasound (AUS).
  • To assess the impact of the adjusted volume estimation on preoperative planning and surgical operating time.
  • To compare the accuracy of the adjusted volume with standard AUS measurements.

Main Methods:

  • A retrospective analysis of 293 patients undergoing transurethral laser enucleation for BPH from 2019-2022.

  • Application of a validated adjustment formula (1.082 × Age + 0.523 × AUS − 53.845) to preoperative AUS volumes.
  • Comparison of adjusted volumes with actual enucleated tissue weights using the intraclass correlation coefficient (ICC) test.

    • Main Results:

    • The adjusted prostatic volume showed a high correlation with enucleated tissue weight (ICC = 0.86, p < 0.001).
    • The adjusted volume estimation was significantly more accurate than standard AUS measurements (weight-to-volume ratio 0.84 vs. 0.7, p < 0.001).
    • The formula demonstrated enhanced precision for prostates weighing over 80g and reduced median operating time by 21 minutes (24%).

    Conclusions:

    • The validated adjustment formula accurately predicts prostatic volume prior to laser enucleation.
    • Improved volume estimation significantly enhances preoperative planning, surgeon expertise matching, and patient expectation management.
    • This method offers a valuable tool for optimizing surgical outcomes in BPH treatment.
