Abstract
Objective

To assess the efficacy and safety of photovaporization of the prostate with Greenlight HPS laser as major outpatient surgery.

Materials and methods

A prospective study was conducted of a cohort of 50 patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia who underwent photovaporization with Greenlight HPS laser (120W) as major outpatient surgery from May 2008 to February 2009.

Inclusion criteria were moderate to severe obstructive lower urinary tract symptoms (IPSS of 10 or more and flowmetry with Qmax of 10ml/sec or less due to benign prostatic hyperplasia with prostate volume less than 80ml.

Preoperative assessment included IPSS; flowmetry; physical examination; ultrasound examination of the kidney, bladder, and prostate (retropubic and transrectal); and measurement of postvoid residue and PSA levels. Surgical data were assessed (vaporization time, operating time, joules, complications during and after surgery). Patients were followed up 1 and 3 months after surgery (PSA, flow rate, IPSS questionnaire).

Results

No patient admission or readmission was required, and bladder catheter was successfully removed from all patients within 24 hours of surgery. Mean patient age was 66.75 years. Mean prostate volume was 44.5ml (SD +/−21). Twenty patients (40%) had prior catheterization. Qmax and postvoid values significantly improved. Major complications at follow-up included voiding syndrome-urgency in 6 patients (12%) and mild transient hematuria in 3 patients (6%).

Conclusions

Photovaporization of the prostate with Greenlight HPS laser may be safely and successfully performed as a major outpatient surgical procedure, which undoubtedly represents a change in care, for surgical treatment of patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia.

Resumen
Objetivo

valorar la eficacia y seguridad de realización del procedimiento fotovaporización láser Greenlight HPS en régimen de cirugía mayor ambulatoria.

Material y métodos

estudio prospectivo de una cohorte de 50 pacientes con sintomatología de tracto urinario inferior secundaria a hiperplasia benigna de próstata, a los que se realizó fotovaporización láser Greenlight HPS (120W) en régimen de cirugía mayor ambulatoria entre mayo de 2008 y febrero de 2009.

Los criterios de inclusión eran moderada o severa sintomatología obstructiva de tracto urinario inferior (IPSS ≥ 10 y flujometría con Qmáx ≤ 10ml/seg) por hiperplasia benigna de próstata con volumen de próstata menor de 80cc.

Evaluación preoperatoria con IPSS, flujometría, exploración física, ecografía renal vesicoprostática (retropúbica y transrectal) con medición de residuo postmiccional y antígeno prostático específico (PSA). Se valoraron los datos operatorios (tiempo de vaporización, tiempo de cirugía, julios, complicaciones intra- y postquirúrgicas). Se efectuó revisión postquirúrgica al mes y a los tres meses (PSA, flujo, cuestionario IPSS).

Resultados

no se requirió ingreso ni reingreso en ningún paciente, retirándose con éxito la sonda vesical en todos los sujetos antes de las 24 horas postquirúrgica. La edad media de nuestros pacientes fue de 66,75 años con un volumen prostático medio de 44,5cc (desviación estándar: ±21). Veinte pacientes (40%) presentaban sondaje previo. Se apreció una mejoría significativa de valores Qmáx y RPM. Las principales complicaciones en el seguimiento fueron: síndrome miccional-urgencia en el 12% (6 pacientes) y hematuria leve transitoria en el 6% (tres pacientes).

Conclusiones

el procedimiento de fotovaporización láser Greenlight HPS puede realizarse de manera segura y satisfactoria en régimen de cirugía mayor ambulatoria, lo que sin duda representa un cambio asistencial en el tratamiento quirúrgico de los pacientes con sintomatología de tracto urinario inferior secundaria a hiperplasia benigna de próstata.
