Summary

Prostate weight, not operating time, is the primary driver of blood loss during transurethral prostatectomy. Surgeons should consider prostate size to better manage bleeding during this common surgical procedure.

Area of Science:

  • Urology
  • Surgical Oncology
  • Medical Engineering

Background:

  • Transurethral prostatectomy is a common procedure for benign prostatic hyperplasia.
  • Minimizing blood loss during surgery is crucial for patient outcomes.
  • Factors influencing blood loss require further investigation.

Purpose of the Study:

  • To investigate the correlation between prostate weight, operating time, and blood loss during transurethral prostatectomy.
  • To determine the primary predictor of intraoperative bleeding.

Main Methods:

  • Retrospective analysis of 417 transurethral prostatectomy cases.
  • Recording of operating time, prostate weight, blood loss, and bleeding rate (ml/min).
  • Statistical analysis including correlation and multiple regression.

Main Results:

  • Significant positive correlation found between prostate weight and blood loss (r = .589).
  • Significant positive correlation found between operating time and blood loss (r = .551).
  • Prostate weight was a stronger predictor of blood loss than operating time.

Conclusions:

  • Prostate weight is the most significant factor influencing blood loss during transurethral prostatectomy.
  • Operating time may represent an iatrogenic factor contributing to bleeding.
  • Preoperative assessment of prostate size can aid in anticipating and managing surgical bleeding.
