A novel technique for thulium laser enucleation of the prostate: anterior releasing with ThuLEP (ARTh technique)

Abstract

Thulium laser enucleation of the prostate (ThuLEP) is a highly effective approach to the treatment of benign prostatic hyperplasia. We present here a description of the ARTh Technique and the benefits it offers in terms of improved visualization, short operation times, and easy recognition of the dissection plane, describing specifically the anterior release (AR) technique using ThuLEP(Th). Included in this retrospective study were 32 consecutive patients operated on between January 2022-November 2022. Parameters were measured before and after the procedure: the International Prostate Symptom Score(IPSS), maximum flow rate(Qmax), post-void residual urine(PVR) prostate-specific antigen(PSA), prostate volume, operation-time, morcellation-time, catheterization-time and presence of transient urinary incontinence, and compared. The median age of patients undergoing enucleation of the prostate using the ARTh technique was 64 years (range: 44-83). The median prostate volume of the patients was 83.5 ml(50-128 ml), preoperative-IPSS was 24.8(15-33), postoperative-IPSS was 7(5-11), preoperative-Qmax was 8.1 ml/Sects. (5-11.5 ml/sec), postoperative-Qmax was 26.9 ml/Sect. (20.8-34 ml/sec), preoperative-PVR was 145 ml(75-258 ml), postoperative-PVR was 36.2 ml(0-66 ml), total operation time was 51.4 min(28-82 min), enucleation time was 36.9 min(19-51 min) and morcellation time was 15.3 min(8-27 min). The ARTh technique is a safe procedure that allows the surgeon to easily recognize and adhere to the defined dissection plane, thus decreasing operation times, significantly reducing the rate of postoperative transient urinary incontinence (TUI).
