A controlled pressure pump was used to dilate the ureteral orifice hydraulically with irrigant flow through the ureteroscope in 50 ureters in 48 patients. The method was successful in all but 1 patient, who had a dense, fibrotic intramural segment that required extensive ureteral meatotomy before the instrument could be inserted. All subsequent procedures (stone removal, relief of obstruction or diagnostic evaluation) were successful, and there were no cases of sepsis or signs of excessive intraureteral or intrapelvic pressure. Hydraulic dilation drastically reduced the time required for ureteroscopy and probably reduced the frequency of complications. Details of the technique and the precautions are provided.
使用可控压力泵通过输尿管镜以冲洗液液压扩张输尿管口，共对48例患者的50条输尿管进行了操作。除1例患者外，该方法均取得成功，该例患者存在致密的纤维化壁内段，在器械插入前需要进行广泛的输尿管口切开术。所有后续操作（结石清除、梗阻解除或诊断评估）均成功，且无脓毒症病例，也未出现输尿管内或肾盂内压力过高的迹象。液压扩张大大缩短了输尿管镜检查所需时间，可能还降低了并发症的发生率。文中提供了该技术的详细信息及注意事项。
