Despite improvements in instrumentation and technology in flexible ureteroscopy, the issue of procedural and off-procedural damage remains a problem. The aim of our study was to highlight our initial experience in flexible ureteroscopy using polyscope, a new advancement in the era of flexible ureterorenoscopy.
In this study, we used an 8F modular flexible, steerable polyscope for diagnostic purposes and Dormia basket removal for small renal stones. Three outer disposable catheters were used with proper sterilization in 22 cases.
The polyscope was used in six cases of undiagnosed hematuria, and biopsy was taken from pelvic growth in one patient, which turned out to be transitional-cell carcinoma. Polyscope was used for removal of residual stones or small stones (< 1 cm) using Dormia basket in 16 cases (from August 2008 to July 2009). The mean stone size was 7.5 mm. The vision achieved was excellent in all the cases.
Minimally invasive techniques are preferred for treatment of renal stones. The problem of lower caliceal stone access has been solved with the primary and secondary deflection of modern flexible ureteroscopes. The modular design of polyscope makes it a more cost-effective option. Relatively cheap and disposable multilumen catheters preclude the need for sterilization of optic cable, thus decreasing the chances of handling-related damages. The chance of instrument-related infection is minimal. Besides, it can be used as a semirigid ureteroscope should the need arises.
尽管软性输尿管镜技术和器械不断进步，但术中和术后损伤的问题仍然存在。本研究旨在强调我们在软性输尿管镜检查中使用 polyscope 的初步经验，这是软性输尿管镜检查时代的一项新进展。
在这项研究中，我们使用 8F 可弯曲、可操控的 polyscope 进行诊断，并使用 Dormia 篮取出小肾结石。在 22 例患者中，我们使用了 3 个一次性外层导管，并进行了适当的消毒。
polyscope 用于 6 例不明原因血尿的诊断，1 例患者从骨盆生长处取活检，结果为移行细胞癌。polyscope 用于 16 例残留结石或<1cm 小结石的取出（2008 年 8 月至 2009 年 7 月）。平均结石大小为 7.5mm。所有病例的视野均良好。
微创技术是治疗肾结石的首选方法。现代软性输尿管镜的初级和次级弯曲解决了下盏结石的进入问题。polyscope 的模块化设计使其成为一种更具成本效益的选择。相对便宜的一次性多腔导管免除了对光导电缆消毒的需要，从而降低了操作相关损伤的可能性。器械相关感染的几率很小。此外，在需要时，它也可以作为半刚性输尿管镜使用。
