The technique of transurethral ureterolithotomy for calculi impacted in the intramural ureter is described. Follow-up date on a group of 30 patients treated by this method are presented. Vesicoureteric reflux was found to occur in almost 50% of cases. The presence of reflux was not found to cause symptoms, infection or renal destruction. Therefore transurethral ureterolithotomy is recommended for the removal of intramural ureteric stones not suitable for basket extraction.
