Rigid transurethral ureteroscopy was used in the treatment of 31 patients with 32 ureteral calculi. The stones could be visualized in 90% of cases. The aim of treatment was immediate extraction under visual control for smaller calculi and retrograde advancement into the renal pelvis with subsequent extracorporeal shock wave lithotripsy for larger calculi. The aim of treatment was reached in 92% (11/12) of stones in the lower third of the ureter, in 67% (4/6) in the middle third and in 64% (9/14) in the upper third of the ureter leaving 12 calculi extracted and 12 pushed up into the renal pelvis. Electrohydraulic lithotripsy in the ureter was used in 3 cases before extraction. Ureterolithotomy had to be carried out in 3 patients only (9%) following the endoscopic procedure.
采用硬性经尿道输尿管镜治疗31例患者的32枚输尿管结石。90%的病例中结石可被观察到。治疗目的是对于较小结石在直视下立即取出，对于较大结石逆行推进至肾盂，随后进行体外冲击波碎石术。输尿管下1/3段结石的治疗目标达成率为92%（11/12），中1/3段为67%（4/6），上1/3段为64%（9/14），12枚结石被取出，12枚被推至肾盂。3例在取出前采用了输尿管内电液压碎石术。仅3例（9%）患者在内镜手术后需要进行输尿管切开取石术。
