Resumen
MALDONADO-ALCARAZ, Efraín et al. Factores predictores del estado libre de cálculos en la primera ureteroscopia flexible con litotricia láser. Gac. Méd. Méx [online]. 2019, vol.155, n.2, pp.162-167. Epub 01-Jul-2021. ISSN 2696-1288. https://doi.org/10.24875/gmm.19004569.
Introduction:
Flexible ureteroscopy and laser fragmentation (FURSL) is a minimally invasive modality for surgical treatment of renal stones. Inadequate selection of patients for this treatment generates a cost-effectiveness unbalance.
Objective:
To know the stone-free rate predictors in a single surgical time in patients undergoing FURSL.
Method:
Retrospective cohort of patients undergoing FURSL. Global and gender-categorized univariate and multivariate (logistic regression) analyses were performed to identify stone-free predictors at first FURSL.
Results:
Stone-free rate at first FURSL was 73.62%. Predictors in males were patient age and stone size, density and multiplicity; in females, body mass index and multiplicity of stones.
Conclusions:
Stone-free rate predictors at first FURSL are different in males and females. Women with overweight and obesity probably have easy-to-fragment and easy-to-extract stones associated with uric acid.
