Summary

Holmium laser enucleation of the prostate outcomes are similar for bilobar and trilobar prostates. Trilobar prostates show a greater decrease in postvoid residual urine volume after the procedure.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Surgical Outcomes

Background:

  • Holmium laser enucleation of the prostate (HoLEP) is a common treatment for benign prostatic hyperplasia.
  • Prostate morphology may influence surgical outcomes.
  • Understanding the impact of prostate shape is crucial for optimizing HoLEP procedures.

Purpose of the Study:

  • To investigate the effect of prostate morphology (bilobar vs. trilobar) on postoperative outcomes following HoLEP.
  • To evaluate the influence of surgical technique on outcomes in patients with trilobar prostates.

Main Methods:

  • Retrospective review of prospectively collected data from 304 patients undergoing HoLEP.
  • Classification of prostate morphology into "bilobar" or "trilobar" based on cystoscopic appearance.

  • Collection and analysis of baseline characteristics, complications, and postoperative outcomes.

    • Main Results:

    • No significant differences in most postoperative outcomes (AUA symptom score, flow rate, complication rate) between bilobar and trilobar groups.
    • Trilobar prostates demonstrated a significantly greater reduction in postvoid residual (PVR) urine volume.
    • Operative times were slightly longer in the trilobar group but not significant on multivariate analysis.

    Conclusions:

    • Trilobar prostate morphology is associated with a more substantial decrease in PVR urine volume after HoLEP.
    • Overall postoperative outcomes are comparable between bilobar and trilobar morphologies.
    • A 2-lobe surgical technique can be safely employed for trilobar prostates when feasible.
