Abstract
— The aim of this work has been to check the frequency and to assess which manoeuvres are necessary in treating the steinstrasse after ESWL. 1779 patients (1360 with renal and 419 with ureteral stones) underwent in-situ ESWL. 68 patients developed a steinstrasse in the immediate 24 hours following treatment. In 85% of the cases (58/68) there was dilation of the urinary tract. In 39 patients the steinstrasse was spontaneously eliminated within 10 days, while in the remaning 29 an auxiliary manoeuvre was necessary. These manoeuvres required further admittance to hospital or prolungation of stay, but created no statistically significant differences in the stone free rate 2 months after treatment (96 and 97% respectively, p< 0.001). Our experience would indicate that the incidence of steinstrasse after ESWL in situ is quite low (3.8%) and the necessity for auxiliary manoeuvres is extremely rare (1.6%).
