Experiencia con la “técnica de Xiao” para reinervación de la vejiga, en pacientes con mielomeningocele y vejiga neurogénica, 8 años de seguimiento, en adultos

Premio Senior. XV Jornadas Argentinas de Neurocirugía de AANC

Abstract

Objective: To restore bladder function in patients with neurogenic bladder through the reinnervation through restauration of somatic-visceral reflex. Record neurosurgical, urological and orthopedic complications. To evaluate technical-surgical difficulties and the results of 5 cases performed in Argentina.
Introduction: Neurogenic bladder is a complication secondary to neurological damage in patients with myelomeningocele (MMC). To achieve emptying of the bladder, intermittent catheterization must be performed. The “Xiao technique” is based on allowing the generation of a visceral somatic-reflex arc by means of an anastomosis between a donor efferent root and the motor root S2-S3 that allows bladder emptying without catheterization.
Material and methods: Through a retrospective descriptive study, the results obtained after performing the “Xiao technique” in 5 patients with MMC and neurogenic bladder were analyzed. The patients were operated at the Rehabilitation Institute (IREP). They were evaluated with a multidisciplinary team, both pre and post-surgery. The team was formed by neurosurgeons, neurologists, urologists, clinicians and kinesiologists.
Results: The patients who presented the best results were the youngest and those who did not present structural damage of the bladder at the time of surgery, which match the results shared by the other centers where this technique was performed.
Conclusions: “Xiao's technique” can be considered an option for the treatment of neurogenic bladder. Although our series is too small to make conclusions, the overall results of all the series show encouraging results.
