Current surgical techniques of enucleation in holmium laser enucleation of the prostate.

ABSTRACT: Holmium laser enucleation of the prostate (HoLEP) has been accepted as the most efficient method of transurethral surgery for benign prostatic hyperplasia. The originally developed three-lobe technique has popularized this surgery; this method is based on three longitudinal incisions, by which the median lobe is removed, and subsequently, both lateral lobes are enucleated. To maintain a consistent surgical plane and to minimize sphincteric damage, the traditional three-lobe technique is continuously being refined and evolving. A few modifications of the original technique have been developed, and several en bloc enucleation methods have been introduced. However, more clinical evidence is required to show the superiority of newer techniques over the original three-lobe technique in terms of efficacy and long-term side effects. To date, none of the newer techniques have been accepted as a standard technique for HoLEP.

Project description:ObjectiveTo demonstrate how bladder ultrasound can be useful in completing morcellation during difficult Holmium Laser Enucleation of the Prostate (HoLEP). As HoLEP has emerged as a standard of care for the treatment of benign prostatic hyperplasia, multiple studies have reported the potentially catastrophic complication of bladder injury during morcellation. This video aims to assist any urologist performing HoLEP by providing step-by-step instruction for using ultrasound to complete morcellation safely.MethodsEnucleation is performed using a 26-French continuous flow scope, off-set laser bridge with a laser stabilization catheter, and a 550 µm holmium laser fiber. Once the median and lateral lobes have been enucleated, the outer sheath is removed and the nephroscope is inserted to facilitate morcellation. Under dual inflow irrigation, the Piranha morcellator (Richard Wolf, Knittlingen, Germany) is introduced and set to the manufacturer's recommended settings of 1500 rpm. A 3.5-MHz convex abdominal ultrasound transducer (Hitachi Prosound Alpha 7; Hitachi Aloka Medical America, Wallingford, CT) under B-mode is used to visualize the bladder, predominantly in the sagittal orientation. Morcellation proceeds under simultaneous ultrasound and direct cystoscopic guidance.ResultsThe distended bladder is visualized concurrently with the ultrasound and via the nephroscope as the Piranha engages the adenoma and begins morcellation. Once the adenoma is engaged, the operator then drops their hands to place the morcellator in the center of the bladder. Ultrasound provides real-time feedback as to the location of the morcellator in relation to the adenoma and bladder.ConclusionThis video highlights the use of intraoperative bladder ultrasound as a visual aid to assist during the morcellation portion of HoLEP. This proof of concept demonstrates that ultrasound can be an additional tool to utilize during difficult cases when cystoscopic visualization during morcellation is limited.
