Conversion of Holmium Laser Enucleation of Prostate to Open Prostatectomy

Adequate Mentorship Program for Holmium Laser Enucleation of the Prostate (HoLEP) Leads to Satisfactory Short-Term Outcomes in the Early Learning Curve of Young Urologists: First-Year Outcomes of a Newly Established Mentorship Training in Mexico

Introduction Benign prostatic hyperplasia (BPH) is one of the most common causes of lower urinary tract symptoms in men. Holmium Laser Enucleation of the Prostate (HoLEP) has been recommended by international guidelines as an alternative to transurethral resection of the prostate (TURP). HoLEP's learning curve and the lack of adequate mentorship remains an obstacle for the worldwide adoption of this technique. Objective To report the first-year learning curve of a newly established mentorship program in young urologists without any previous HoLEP experience. Methods We report a cohort of patients with BPH, with prostate size ≥70 grams, treated with HoLEP, analyzed for perioperative data and complications, and short-term postoperative complications and functional outcomes, at three and six months after surgery. Results A total of 47 patients were managed with HoLEP. Mean total operative time was 149.8 ± 42.9 minutes. We experienced five (10.6%) intraoperative complications, including one intravesical resection of the prostate with bipolar energy, three conversions to TURP and one conversion to open prostatectomy. We experienced four postoperative complications, all of them Clavien-Dindo ≤2. Median International Prostate Symptom Score (IPSS) decrease at six months was -17 points from baseline. Mean post-void residual volume and prostate-specific antigen significantly decreased by the third postoperative month. Multiple linear regression showed that prostate size is directly related to increased surgical time during the early learning curve. Discussion Our experience adequately reflects the importance of HoLEP mentorship in young urologists seeking training in this technique. Both surgeons had perioperative and postoperative outcomes deemed satisfactory based on previously published learning curves. Conclusions HoLEP is a technically difficult procedure, however, adequate mentorship leads to satisfying short-term outcomes since the early stages of the learning curve in young urologists with no previous training on this technique.

Early apical release versus En-bloc no touch technique for holmium laser enucleation of the prostate: a high-volume single-surgeon cohort study

PURPOSE

To determine whether the early apical release (EAR) technique for holmium laser enucleation of the prostate (HOLEP) is associated with improved perioperative outcomes compared to the En-bloc no touch (EBNT) technique.

METHODS

Consecutive men treated with HOLEP by a single surgeon from August 2018 to March 2021 were identified. Beginning in June 2021 all procedures were performed using the EAR technique, and these were compared to the preceding cases done with the EBNT technique. Intraoperative outcomes included operative time, need for open conversion, enucleation efficiency (tissue removed per minute of OR time), and enucleation ratio (tissue removed relative to preoperative gland size on imaging). Postoperative outcomes included catheter reinsertion, blood transfusion, and complications classified by the Clavien-Dindo scale.

RESULTS

We identified 801 men, including 571 (71%) treated with EBNT and 230 (29%) with EAR. Median preoperative characteristics were similar between groups. The EAR approach was associated with significantly longer mean operating room time, 100.5 min versus 91.9 min, p = 0.003. However, EAR patients had a much lower rate of conversion to open cystotomy (0.43% versus 3.0%). There were no significant differences in rate of catheter reinsertion or perioperative complications between groups (p > 0.05).

CONCLUSION

EAR technique by an experienced HoLEP surgeon resulted in longer operative times, potentially reflecting an initial learning curve, but essentially eliminated the need for open cystotomy. Perioperative results including catheter reinsertion rate and bleeding complications were similar between the two cohorts. These data support continued use of the EAR technique for HOLEP to minimize risk of open conversion.
