Abstract:
Objective To study therapeutic effects of ureteroscopic treatment for ureteral stones after failed extracorporeal shock wave lithotripsy (ESWL). Methods A total of 23 patients with ureteral stones received ureteroscopic treatment after the ESWL had failed. By using pneumatic lithotripter and self-made needle-shaped electrotome, stones were fragmented and removed, and polyps were resected. Results Two patients with stones fragmented but surrounded by granuloma tissue received a polyp resection and stone extraction.Pneumatic ballistic lithotripsy and stone removal was conducted in 16 patients with stones partly fragmented.In 4 patients with stones adherent to the ureteral wall and polyps,the polyps were removed by using self-made needle-shaped electrotome and the stones were fragmented and extracted.And in 1 patient with stones embedded beneath the ureteral mucous membrane, which was difficult to be expelled,the mucous membrane covering the stones was opened by using the needle-shaped electrotome and the stones were fragmeathed and extracted.The procedure duration was 30~55 min(mean,42 min).Re-examination 6 months postoperatively found no residual stones. Conclusions After the ESWL had failed, patients with ureteral stones can be treated ureteroscopically by using pneumatic lithotripsy and self-made needle-shaped electrotome.
