Safety and effectiveness of high-power thulium laser enucleation of the prostate in patients with glands larger than 80?mL.

ABSTRACT: BACKGROUND:The efficacy of thulium laser prostate enucleation (ThuLEP) for large prostates is unclear. This study aimed to explore the expanded utility of 150-200-W ThuLEP by studying patients with a large prostate (>?80?mL). METHODS:We retrospectively reviewed records of 125 patients with large prostate glands (>?80?mL) who underwent ThuLEP performed by a single surgeon from June 2012 to June 2016. The ThuLEP data from our previous pilot study were used as the control. Operative variables, patient profiles, preoperative and postoperative urine flow rates, prostate volume, and the international prostate symptom score (IPSS) were recorded and analyzed using Student's t-test, the z-test, and logistic regression analysis. RESULTS:Of 366 patients who underwent ThuLEP, 125 (34.15%) were enrolled. The ages and estimated prostate volumes were compared with those of the control. Overall, 39.2% underwent Foley placement and 4% received an anticoagulant agent preoperatively. Maximum urinary flow rates before and 3 and 12?months postoperatively were 9.93, 23.20, and 19.00?mL/s, respectively, which were generally equal to those of the control groups (P =?0.68, 0.18, 0.98, respectively). Preoperative and postoperative IPSSs were 27.09 and 7.35, respectively. The postoperative prostate-specific antigen was reduced by 85.59% in comparison to the preoperative level. The estimated prostate size was reduced by 74.17% postoperatively. The modified Clavien-Dindo classification system was used to identify the overall rate of complications, which was approximately 22.4%. The mortality rate was 0.8%. CONCLUSIONS:High-power ThuLEP is safe and effective for patients with large prostate glands (>?80?mL). Prostate enucleation using a high-power thulium laser is feasible for patients who exhibit contraindications for surgery.

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.
