title: Transurethral holmium-YAG laser lithotripsy for large symptomatic prostatic calculi: initial experience.
abstract: Symptomatic prostatic calculi are a rare clinical entity with wide range of management options, however, there is no agreement about the preferred method for treating these symptomatic calculi. In this study we describe our experience of transurethral management of symptomatic prostatic calculi using holmium-YAG laser lithotripsy. Patients with large, symptomatic prostatic stones managed by transurethral lithotripsy using holmium-YAG laser over 3-year duration were included in this retrospective study. Patients were evaluated for any underlying pathological condition and calculus load was determined by preoperative X-ray KUB film/CT scan. Urethrocystoscopy was performed using 30° cystoscope in lithotomy position under spinal anesthesia, followed by transurethral lithotripsy of prostatic calculi using a 550 μm laser fiber. Stone fragments were disintegrated using 100 W laser generators (VersaPulse PowerSuite 100 W, LUMENIS Surgical, CA). Larger stone fragments were retreived using Ellik's evacuator while smaller fragments got flushed under continuous irrigation. Five patients (median age 42 years) with large symptomatic prostatic calculi were operated using the described technique. Three patients had idiopathic stones while rest two had bulbar urethral stricture and neurogenic bladder, respectively. Median operative time was 62 min. All the patients were stone free at the end of procedure. Median duration of catheterization was 2 days. Significant improvement was observed in symptoms score and peak urinary flow and none of the patient had any complication. Transurethral management using holmium-YAG laser lithotripsy is a safe and highly effective, minimally invasive technique for managing symptomatic prostatic calculi of all sizes with no associated morbidity.
