A total of 130 patients with symptomatic lower third ureteral calculi underwent 136 treatments by 43 accredited urologists. These treatments were performed at a fixed lithotripsy site and 16 mobile sites using the Medstone lithotriptor from December 1990 through January 1992. The average stone size was 8.16 x 5.14 mm. A total of 126 patients underwent a single treatment and 4 underwent multiple treatment sessions. Of the 126 patients undergoing monotherapy 10 (8%) were lost to followup, while 101 of the remaining 116 evaluable patients (87%) were stone-free with a single treatment. The 15 patients in this subgroup who were considered failures and the 4 patients who underwent multiple treatments had overall larger stone sizes. The preoperative stent placement rate was only 32%. The treatments were well tolerated by the patients. Our report confirms a high efficacy rate with the second generation bathless lithotriptor for management of lower third ureteral calculi. The importance of a stable and qualified technical team cannot be overemphasized.
1990年12月至1992年1月期间，43名经认可的泌尿外科医生对总共130例有症状的输尿管下段结石患者进行了136次治疗。这些治疗在一个固定的碎石地点和16个移动地点使用Medstone碎石机进行。结石平均大小为8.16×5.14毫米。共有126例患者接受了单次治疗，4例接受了多次治疗。在接受单一疗法的126例患者中，10例（8%）失访，其余116例可评估患者中的101例（87%）单次治疗后结石清除。该亚组中被视为治疗失败的15例患者和接受多次治疗的4例患者结石总体更大。术前支架置入率仅为32%。患者对治疗耐受性良好。我们的报告证实，第二代无水浴碎石机治疗输尿管下段结石疗效高。稳定且合格的技术团队的重要性再怎么强调也不为过。
