Abstract Objective: To present our experience in relation to the safety and efficacy of the 180W Greenlight XPS laser for photoselective vaporization of the prostate. Materials and methods: A retrospective, observational, analytic, and descriptive study was conducted within the time frame of July 2014 to November 2017, evaluating technical aspects and preoperative and postoperative variables at 1, 3, and 6 months. Results: Fifty-five patients were included in the study. Their mean age was 69 years. A total of 49.1% presented with comorbidities, 14.5% with heart disease, and 20% with an ASA III. The preoperative parameters were: IPSS 14.5 points (5-35), Qmax 7.19 ml/sec (1.5-12), prostate volume 74 cc (29.2-130), PSA 5.7 ng/ml, and Foley catheter placement (54%). Laser use, time with catheter, previous infections, and previous biopsy were described, as were intraoperative complications (10.8%), postoperative complications (27.3%), Clavien-Dindo (C-D) I (80.2%), C-D II (6.6%), and C-D IIIa (13.2%). Postoperative control at 6 months was: Qmax 17.2 ml/sec (10.2-34.4) (p=0.01) and IPSS 4.2 points (0-19) (p=0.02). Surgical reintervention was performed in 3.6% of the patients, hospital stay was 1.5 days, and the mortality rate was 0%. Conclusions: Photoselective vaporization of the prostate with the GreenLight laser is a safe surgical technique with good results in high-risk surgical patient populations. Complications are similar to those when utilizing the gold standard, but patients taking anticoagulants and antiaggregants can be operated on with the technique and hospital stay is short. Studies with long-term follow-up are needed.
Resumen Objetivo: Presentar experiencia en seguridad y eficacia con el láser GreenLight XPS de 180w para fotovaporización selectiva de la próstata (FVP). Materiales y Métodos: Se realizó un estudio retrospectivo, observacional, analítico y descriptivo (de julio de 2014 a noviembre de 2017). Se evaluaron aspectos técnicos, así como variables pre y posquirúrgicas al primer mes, tercero y sexto. Resultados: 55 pacientes, media de 69 años, 49.1% con comorbilidades, 14.5% cardiopatías, asaiii 20%. Parámetros prequirúrgicos: ipss 14.5(5-35)pts, Qmax 7.19(1.5-12)ml/seg, volumen prostático 74(29.2-130)cc, ape de 5.7ng/ml, 54% portadores de sonda foley. Se describen parámetros de uso de láser, tiempo de sonda, infecciones previas y biopsia previa, complicaciones transoperatorias 10.8% y postoperatorias 27.3%, Clavien-Dindo (CV) I en 80.2%, cvii 6.6% y cviiia 13.2%. Controles postquirúrgicos 6 meses: Qmax 17.2(10.2-34.4)ml/seg (p=0.01) e ipss 4.2(0-19)pts (p=0.02). Reintervención quirúrgica 3.6%, 1.5 días de estancia intrahospitalaria y una mortalidad de 0%. Conclusiones: La cirugía fvp con GreenLight es una técnica quirúrgica segura, con buenos resultados en poblaciones de pacientes con alto riesgo quirúrgico, las complicaciones no son mayores que el estándar de oro, pero los pacientes con anticoagulantes y antiagregantes pueden ser operados con esta técnica, con poco tiempo de hospitalización. Se requiere seguimientos a largo plazo.
