[Is ureteral dilatation necessary in ureterorenoscopy?].
A retrospective analysis of 136 patients, who were submitted rigid ureteroscopy for stone removal, was performed. Patients were divided into two groups. First group consisted of 63 patients with routine balloon dilation of intramural part of ureter before ureteroscopy. 73 patients of the second group were submitted ureteroscopy without previous ureter dilation. The total success rate was achieved in the first and second group of the patients in 90.5% and 91.8%. The success rate achieved in removing of the stone of upper, middle and lower part of the ureter was in the first group 81.8%, 88.9% and 94.1% and in the second group 78.6%, 95%, 94.9%, respectively. None of the patients have demonstrated vesico-renal reflux. With respect to our similar success rate in both of the groups they don't consider routine dilation of ureter as necessary before ureteroscopy.
