Transurethral Holmium: YAG Laser Prostatectomy Using a Side–Firing Fiber for Bladder Outlet Obstruction due to Benign Prostatic Enlargement: Urodynamic Evaluation of Surgical Outcome

Objectives: To prospectively assess the efficacy of transurethral holmium (Ho):YAG laser prostatectomy using a side–firing fiber in patients with bladder outlet obstruction due to benign prostatic enlargement (BPE) from the standpoint of urodynamics. Methods: 32 male patients with BPE aged 53–83 (mean 69.4) years were operated on. All patients, excluding 3 with urinary retention, were evaluated with the International Prostatic Symptom Score (IPSS), Quality of Life (QOL) score and uroflowmetry up to 12 months postoperatively, and a pressure/flow study was performed before and 3 months after the operation. Results: The total IPSS score, QOL score, average and maximum flow rates improved significantly (p
