With the development of science and technology, the treatment of urinary calculi surgery ushered in a major reform, from the traditional open surgery gradually replaced by endoscopic minimally invasive surgery. Flexible ureteroscopy in the treatment of renal calculi is through the natural urethra into the kidney laser lithotripsy.

下面小编整理了一些纤维输尿管软镜的优势：

Here are some advantages of flexible ureteroscope

1、适应症广，术后恢复 快 手术过程中对生理组织损伤小，能有效减少术后并发症的发生。术后平均住院时间为5-7天，患者能在短期内恢复健康。

1. It can effectively reduce the incidence of postoperative complications. The average postoperative hospital stay was 5-7 days, and the patients could recover in a short time.

2、手术无创，保护肾脏无损伤 纤维软性肾镜经人体泌尿系统自然通道进入输尿管及肾脏，配合的取石/碎石设备取出泌尿系结石，保护肾脏的同时不会在患者体表留下任何创口。

2. The operation is non-invasive, and the kidney is protected from damage. The flexible nephroscope enters the ureter and kidney through the natural passage of human urinary system, and the advanced lithotripsy / lithotripsy equipment is used to remove the urinary calculi, so as to protect the kidney without leaving any wound on the patient's body surface.
             

3、定位准确，碎石率更高 手术在清晰视野引导及结石准确定位下，配合双导管、钬激光等碎石设备将其击碎后使其排出体外，结石取净率更高。

3. Under the guidance of clear vision and accurate positioning of the stone, combined with double catheters, holmium laser and other advanced lithotripsy equipment, the stone can be crushed out of the body, and the stone removal rate is higher.

4、软镜，手术视野广阔 术中使用的纤维软性肾镜镜体纤细柔软，镜头可转动弯曲180度，逆行进入肾盂各小盏，快速、准确地找到结石，手术视野广阔清晰。

4. The advanced flexible nephroscope has a wide operative field of vision. The flexible nephroscope used in the operation is thin and soft. The lens can be rotated and bent 180 degrees to retrograde into the small calices of the renal pelvis to quickly and accurately find the stones. The operative field of vision is broad and clear.

5、导引鞘，人体腔道伤害小 遵循人体工学设计的输尿管导引鞘拥有亲水涂层，能降低表面摩擦，使手术插入更容易。其前端呈平滑长锥形，可一步扩张到位，减少创伤。

5. The ureteral sheath designed according to ergonomics has hydrophilic coating, which can reduce the surface friction and make the operation easier. Its front end is a smooth long cone, which can be expanded in one step to reduce trauma.
