However, treatment success is negatively affected by stone impaction or associated urinary obstruction. In order to assess the impact of obstruction on the outcome of in situ ESL, we reviewed the results in 503 patients treated in this way. The presence and severity of urinary obstruction was defined prior to ESL, being classified as no or mild obstruction (Group I) and… CONTINUE READING
