Abstract:
Objective To discuss the techniques and efficacy of Ho:YAG laser incision by using uteroscopy for ureterostenosis.Methods From July 2004 to April 2007,52 patients with ureterostenosis received ureteral incision by using Ho:YAG laser under a endoscope.Two double pigtail stents(F5 or F6) were placed in the ureters after the operation and left indwelling for 8 to 12 weeks.Ultrasonography and excretion urography were performed 3 to 6 months after extubation.Results Follow-up was available for 3 to 24 months(mean,17 months) in 46 patients,of which 40(87%) were cured after the treatment.In the cured patients,hydronephrosis,ureteral dilation,and ureterostenosis were improved,and the pain in the kidney region was relieved;none of them showed signs of infection.In the other 6 patients,4 were improved after the treatment(no deterioration of the symptoms of hydronephrosis,ureteral dilation,and pain in the kidney region,and no infection);and 2 failed(the symptoms of hydronephrosis and ureteral dilation deteriorated,and pain in the kidney region and infection were developed).Conclusion Endoscopic ureteral excision using holmium laser combined with indwelling of two double pigtail stents is effective and safe for ureterostenosis.
