Factores condicionantes de éxito o fracaso del tratamiento endoscópico en el reflujo vesicoureteral primario pediátrico:: una revisión sistemática
2021
OBJECTIVE: The objective of this paper is
identifying the factors that may condition the success or
failure of endoscopic therapy for vesicoureteral reflux in
the paediatric population.
MATERIAL AND METHODS: A bibliographic review
was performed in the Cochrane Library and PUBMED of all the studies which the principal subject was about
identifying factors involved in the success or failure of
endoscopic therapy for vesicoureteral reflux in the pae-
diatric population.
RESULTS: Of a total of 1410 studies, 14 studies and
17 factors potentially involved in the success or failure
of endoscopic therapy were fully analysed according to
the different studies reviewed.
After analyzing these studies, we identified that the most
widely accepted factors that determine the success or
failure of endoscopic therapy are the high degree of
pre-surgical reflux, the previous injection of antireflux
material, the surgical experience and the presence of
dysfunction of the lower urinary tract (UTD).
Other factors such as the amount of bulking substance
used, meatal morphology, renal damage and age at the
time of injection could be potentially involved.
The technique used and the bulking material do not
seem to be associated with the response to therapy.
Exists a great heterogeneity of the reviewed studies, both
in relation to the characteristics of the patients included,
criteria and surgical technique and evaluation of results.
CONCLUSIONS: The degree of pre-surgical reflux, the
presence of UTD, previous injections and surgical expe-
rience are the most widely accepted determining factors
in the results of endoscopic therapy according to the
different studies published in this topic.
