Outcomes Of The Holmium Laser Enucleation Of The Prostate For Patients With Prior Benign Prostatic Hyperplasia Surgery

Background: To assess the functional outcomes and morbidity in patients undergoing holmium laser enucleation of the prostate (HoLEP) with and without previous transurethral prostate surgery.Methods: Patients were stratified into two groups, 558 patients who underwent primary HoLEP (group I) and 50 patients who underwent 'secondary-HoLEP' with prior transurethral prostate surgery (group II).Results: There were no significant differences in the preoperative parameters (median age, International Prostate Symptom Score [IPSS], prostate-specific antigen [PSA], prostate volume, maximum urinary flow rate [Qmax], and postvoid residual urine volume [PVR]). No significant intraoperative differences were noted in the use of total energy, resected volume, enucleation time, resection efficiency, and mean catheterization time. There were significant improvements in Qmax, PVR, and IPSS in both groups. Complications in groups I and II included 19 (3.1%) and 1 (2.0%) bladder injuries, 25 (4.4%) and 2 (4.0%) recatheterization for transient voiding difficulty, 20 (3.5%) and 2 (4%) cases of severe hematuria requiring additional treatment, and 5 (0.8%) and 0 cases for remorcellation due to remaining adenoma. Transient incontinence was the most common complication for both groups I and II, 30 cases (5.4%) and 3 cases (6.0%) respectively. Urinary tract infection showed improvement subsequent to antibiotic treatment. During the 6 month follow-up period, urethral stricture occurred in 7 cases (1.3%) for group I and in 1 case (2.0%) for group II.Conclusion: There were no significant differences in functional outcomes and morbidity between the two groups. 'Secondary-HoLEP' seems to be effective and safe for patients with prior BPH surgery.
