A Novel Modified Two-Lobe Holmium Prostate Enucleation Technique: Demirtaş-Erciyes Enucleation Prostatectomy

Abstract

Objective Endoscopic enucleation of the prostate has evolved and became popular for the surgical treatment of benign prostatic hyperplasia (BPH) during the last decade. Different surgical techniques have been described so far. We hereby described a new modified two-lobe technique for urologists who are inexperienced in endoscopic enucleation. We aimed here to present the data on a learning curve of this stepwise technique named Demirtaş-Erciyes Enucleation Prostatectomy (DEEP): reverse S-J incision technique and its postoperative outcomes. Material and methods The study included 102 patients who underwent holmium laser enucleation of the prostate (HoLEP) with the DEEP technique between October 2020 and December 2021. Demographic, preoperative, and postoperative variables were recorded. The operation was performed with a 150 W holmium laser system (Quanta System, Varese, Italy) with cutting and coagulation settings of 2J × 50 Hz with virtual basket mode and 2J × 12 Hz in bubble blast mode, respectively. Bladder irrigation was done for one day, and then, on the next day, the urethral catheter was removed. Postoperatively, uroflowmetry studies, continence status, and ejaculation status were recorded during follow-up. The data of all patients were divided into two groups (first 51 and final 51 patients). All variables were analyzed between two groups. Results The mean age of the patients was 68.48±8.74 years. The median Charlson Comorbidity Index (CCI) score was 3. The median International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) values ​​were 26 (10-35) and 10 (0-25), respectively. Of the patients, 60.8% had Foley catheters due to urinary retention. The median anesthesia time, laser time, enucleation time, morcellation time, and enucleated tissue amount were 102.5 minutes, 17 minutes, 25 minutes, 20 minutes, and 50 g, respectively. Enucleation was performed in two stages in five patients due to bigger prostate volume or incomplete morcellation. The median catheter removal time was 48 hours. In six patients, the postoperative catheterization time was prolonged due to hematuria. The median increase in Qmax was 19.35 mL/second. The overall complication rate was 5.9%, which were all Clavien grade II. Enucleation time, laser time, and anesthesia time were significantly lower in the last 51 patients. Conclusion DEEP enucleation technique seems to provide effective and safe postoperative results for beginners in prostate enucleation.
