Análisis coste efectividad a 2 años del tratamiento quirúrgico de la hiperplasia benigna de próstata mediante vaporización fotoselectiva de la próstata con GreenLight-PhotoVaporization 120 W versus resección transuretral de la próstata / Cost-effectiveness analysis at 2 years of surgical treatment of benign prostatic hyperplasia by photoselective vaporization of the prostate with GreenLight-Photo vaporization 120 W versus transurethral resection of the prostate

Introducción: El gold standard del tratamiento quirúrgico de la sintomatología del tracto urinario inferior asociado a la hiperplasia benigna de próstata ha sido la resección transuretral de la próstata; GreenLight-PhotoVaporization ha demostrado ser una alternativa quirúrgica tan efectiva como aquella. Objetivo: Analizar la eficiencia comparada, en un horizonte temporal de 2 años, de GreenLight-PhotoVaporization 120 W respecto de la resección transuretral de la próstata en el tratamiento quirúrgico de la hiperplasia benigna de próstata desde la perspectiva del sistema de salud de España. Métodos: Se realizó un análisis de coste utilidad a partir de los resultados obtenidos retrospectivamente en 98 pacientes intervenidos secuencialmente mediante resección transuretral de la próstata (n: 50) y GreenLight-PhotoVaporization 120 W (n: 48). Se utilizó un modelo de Markov para estimar el coste (Euros, 2012) y los resultados (años de vida ajustados a calidad) tras un seguimiento de 2 años. Resultados: El coste total asociado al tratamiento con GreenLight-PhotoVaporization 120 W fue inferior (3.377 Euros; IC 95%: 3.228; 3.537) al de la resección transuretral de la próstata (3.770 Euros; IC 95%: 3.579; 3.945). El determinante del coste se presenta en la fase quirúrgica (diferencia: -450 Euros; IC 95%: -625; -158) debido a que GreenLight-PhotoVaporization 120 W no precisaba ingresar al paciente tras la cirugía. Conclusiones: El tratamiento quirúrgico de los pacientes con HBP mediante GreenLight-PhotoVaporization 120 W muestra mayor eficiencia respecto de la resección transuretral de la próstata al observarse una efectividad similar y un coste inferior (-393 Euros; IC 95%: -625; -158)

Introduction: Transurethral resection of the prostate is the gold standard of surgical treatment of lower urinary tract symptoms associated to benign prostate hyperplasia. The new Green Light Photovaporization has been shown to be an alternative that is as effective for this condition as the transurethral resection of the prostate. Objectives: To compare the efficiency of Green Light Photovaporization 120 W versus transurethral resection of the prostate in the treatment of benign prostate hyperplasia (BPH) in a 2-year time horizon from the perspective of the Spanish health service perspective. Methods: A cost utility analysis was performed retrospectively with the data from 98 patients treated sequentially with transurethral resection of the prostate (n: 50) and Green Light Photovaporization 120 W (n: 48). A Markov model was designed to estimate the cost (2012 Euro) and results (quality adjusted life years) in a 2-year time horizon. Results: The total cost associated to Green Light Photovaporization 120 W treatment was less (3,377 Euros; 95% CI: 3,228; 3,537) than that of the transurethral resection of the prostate (3,770 Euros; 95% CI: 3,579; 3,945). The determining factor of the cost was the surgical phase (difference: −450 Euros; 95% CI: −625; −158) because admission to hospital after surgery was not necessary with the GreenLight-PhotoVaporization. Conclusions: Surgical treatment of BPH patients with GreenLight-PhotoVaporization 120 W is more efficient than transurethral resection of the prostate in the surgical treatment of benign prostate hyperplasia as it has similar effectiveness and lower cost (-393 Euro; 95% CI: -625; -158)
