Endopielotomía retrógrada con láser / Retrograde laser endopyelotomy

La Estenosis de la Unión Pieloureteral (EUPU) es la anomalía congénita más frecuente del tracto urinario superior. Hasta hace unos años, el tratamiento de primera elección era la pieloplastia abierta, pero el desarrollo de la cirugía endoscópica y la mejora técnica en la instrumentación de la misma, permite su tratamiento de forma minimamente invasiva, ofreciendo las ventajas de un menor tiempo operatorio, una menor morbilidad, disminución de analgesia en el postoperatorio, estancia hospitalaria más corta y un menor periodo de convalecencia. La Endopielotomía Retrógada representa la evolución natural del tratamiento quirúrgico mínimamente invasivo de la EUPU al eliminar la necesidad de un trayecto percutáneo renal y sus posibles complicaciones. Puede ser realizada de tres formas: con ureteroscopio semirrígido e incisión con electrocauterio, corte frío o láser; con ureteroscopio flexible e incisión con electrocauterio o láser; y bajo control de escopia con el catéter balón de corte AcuciseTM. En la actualidad, el desarrollo de ureterorrenoscopios de menor calibre (semirrígidos y flexibles) y el uso de fuentes de energía más seguras y eficaces, como el láser de holmium-YAG, han mejorado los resultados de esta técnica. Se presenta la técnica de realización y una revisión de la literatura (AU)

Ureteropyelic junction obstruction (UPJO) is the most frequent congenital anomaly of the upper urinary tract. Until some years ago, the treatment of first choice was open pyeloplasty, but the development of endoscopic surgery and the clinical improvement on instruments, enables the treatment in a minimally invasive fashion, offering the advantages of shorter operative time, less morbidity, reduction of post operative analgesic requirements, shorter hospital stay, and shorter convalescence period. Retrograde endopyelotomy represents the natural evolution of the minimally invasive surgical treatment of the UPJO by eliminating the need of a percutaneous renal tract and its possible complications. It may be performed in three ways: semirigid ureteroscope and electrocautery, cold knife or laser incision; flexible ureteroscope and electrocautery or laser incision; and under x-ray control with the AcuciseTM cutting balloon catheter. Currently, the development of smaller ureterorenoscopes (semirigid and flexible) and the use of safer and more effective energy sources, such as holmium:YAG laser, have improved the results of this technique. We present the technique step-by-step and a bibliographic review (AU)
