To assess the success rates of endoscopic management of upper ureteral stones using semirigid ureterorenoscopy and holmium: YAG laser lithotripters.
A total of 74 patients with an established diagnosis of upper ureteric stone and scheduled for endoscopic ureteral stone treatment were retrospectively evaluated. Failure was defined as the inability to contact or fragment the stone, migration of the stone into the renal pelvis and difficulty in visualizing the stone for the second time. Success rates and influencing factors as for stone-free state were investigated.
Mean age of our patients was 45.99±15.00 (range: 24-82) years. In 14 of 74 patients procedural failure was observed. Double J stents were implanted in 65 % of the patients and ureteral catheterization was performed on 20% of them. The total success rate was 81.1 %. Major complication rate was 1.1 percent. Factors effecting the success rate as gender, age, body mass index, grade of hydronephrosis and stone size were evaluated and only age was found to be statistically significant.
Despite some potential risks, semirigid ureterorenoscopic stone extraction and holmium: YAG laser lithotripters are still safe and effective treatment alternatives for management of upper ureteral stones.
评估使用半硬性输尿管肾镜和钬：钇铝石榴石激光碎石器进行输尿管上段结石内镜治疗的成功率。
回顾性评估了74例确诊为输尿管上段结石并计划接受内镜输尿管结石治疗的患者。失败定义为无法接触或粉碎结石、结石移入肾盂以及再次观察结石困难。研究了无结石状态的成功率及影响因素。
患者的平均年龄为45.99±15.00（范围：24 - 82）岁。74例患者中有14例观察到手术失败。65%的患者植入了双J支架，20%的患者进行了输尿管插管。总成功率为81.1%。主要并发症发生率为1.1%。评估了性别、年龄、体重指数、肾积水程度和结石大小等影响成功率的因素，发现只有年龄具有统计学意义。
尽管存在一些潜在风险，但半硬性输尿管肾镜取石术和钬：钇铝石榴石激光碎石器仍是治疗输尿管上段结石的安全有效的替代方法。
