ABSTRACT
Objetive In this study, we aimed to determine the factors predicting the duration and successof semirigid ureteroscopy performed for the treatment ofureteral stones in different localizations.Materials and

methods:

Medical records of thepatients whom underwent semirigid ureteroscopy forurolithiasis in our centre between January 2015 and December 2019 were retrospectively reviewed. The studygroup composed of 170 patients and divided into threesubgroups; of which 54 in proximal ureter (31.8%), 51in the mid (30 %) and 65 (38.2%) in the distal ureter.Predictive factors of semirigid ureteroscopy duration andsuccess were determined by performance of correlationanalysis and multivariate analysis. R

results:

Overall stone-free rate was calculated as78.8%. Success rates for proximal, mid and distalureteral stones were 72.2% (39/54 patients), 74.5%(38/51 patients) and 87.7% (57/65 patients), respectively. Complications were present in 19 patients(11.2%). Multivariate analysis indicated that stone diameter and stone burden independently affected thestone-free rate. Statistically significant negative correlation was determined between success of the procedureand stone diameter, stone burden, impaction and moreproximal stone localization. While there was a statistically significant positive correlation between duration ofprocedure and stone burden, diameter, impaction, history of ipsilateral ureteroscopy and more proximal stonelocalization, there was negative correlation betweenduration of procedure and stone-free status.

Conclusion:

We conclude that stone diameter,stone burden, impaction and more proximal stone localization are common factors affecting both durationand success of semirigid ureteroscopy. In addition, stonesize and stone burden were determined as independentmarkers of stone-free status.(AU)
RESUMEN

Objetivo:

En este estudio determinamoslos factores predictores de la duración y el éxito de laureteroscopia semirígida realizada como tratamiento delas litiasis ureterales en diferentes localizaciones.Materiales y

métodos:

Revisamos retrospectivamente las historias clínicas de los pacientes que han sido sometidos a una ureteroscopia semirígida por litiasis ennuestro centro entre enero 2015 y diciembre 2019. Elgrupo de estudio está formado por 170 pacientes y dividido en 3 subgrupos 54 con litiasis en uréter proximal(31,8%) 51 en medio (30%) y 65 (38,2%) en el uréterdistal. Los factores predictores de duración y éxito de laureteroscopia semirígida fueron determinados con análisis de correlación y multivariante.

RESULTADOS:

La tasa global libre de litiasis fue de78,8%. La tasa de éxito en uréter proximal, medio y distal fue de 72,2% (39/54 pacientes), 74,5% (38/51pacientes) y 87,7% (57/65 pacientes), respectivamente. Las complicaciones estuvieron presentes en 19 pacientes (11,2%). El análisis multivariante indicó que eldiámetro de la litiasis y el volumen afectaron de formaindependiente la tasa libre de litiasis. Una significaciónestadística negativa fue determinada entre el éxito delprocedimiento y el diámetro de la litiasis, volumen, impactación y localización proximal. Una significación estadística positiva entre la duración del procedimiento yel volumen de la litiasis, diámetro, impactación, previasureteroscopias y localización proximal. Se observó unacorrelación negativa entre la duración del procedimiento y el estado libre de litiasis.

CONCLUSIÓN:

Concluimos que el diámetro de la litiasis, volumen, impactación y localización proximal sonlos factores que afectan a la duración y el éxito de laureteroscopia semirígida. Además, el tamaño de la litiasis y el volumen fueron predictores independientes de latasa libre de litiasis.(AU)
