Resumen

Se presentan los resultados y complicaciones obtenidos en 360 procedimientos de ureterorrenoscopia transuretral (U.R.S.) por litiasis ureteral, realizados en nuestro Servicio desde enero de 1990 hasta agosto de 2000 en 354 pacientes: 55% mujeres y 45% varones. Se ha utilizado un ureterorrenoscopio rígido Storz 10.5 Ch. y ha sido necesario emplear litotricia intracorpórea en un 17,31% de los casos. En todos los procedimientos la indicación fue el tratamiento de litiasis ureterales con predominio de localización en el uréter pelviano (70,33%), obteniendo un porcentaje de éxito global del 93,05% descendiendo de forma significativa a nivel del uréter lumbar. Las complicaciones serias sólo representaron un 3,05% precisando cirugía correctora endoscópica en tres casos de estenosis ureteral. En nuestra experiencia, la U.R.S. es la técnica de elección en el tratamiento de la litiasis ureteral a nivel pelviano y sacroiliaco donde los porcentajes de éxito alcanzados son de 98,88% y 95,83% respectivamente.

Abstract

Presentation of results and complications obtained in 360 procedures of transuretral ureterorenoscopy (URS) in ureteral lithiasis performed in our unit from january 1990 to august 2000 in 354 patients: 55% female and 45% male.

A rigid ureteroscopy Storz 10.5 Ch. was used and intracorporeal lithotripsy was necessary in 17.31% of cases. URS indications were always treatment of ureteral lithiasis, pelvic ureter localization in most cases (70.33%) beeing 93.05% the percentage of overall success and with a significant decrease when the calculus was located in the upper third of the ureter.

Serious complications were only 3.05% of cases and endoscopic surgery was necessary in three cases of ureteral stenosis. In our experience, URS is our technique of choice for treatment of lower and medium third of the ureter where the percentage of success we have obtained were 98.99% and 95.83% respectively.
