Dilatation of a percutaneous nephrostomy track is essential for procedures such as stone or foreign-body removal and nephroscopy. In 140 patients, a technique was used of rapid dilatation to 24 French. It required only a few minutes. This procedure proved to be safe, easy to master, and the materials are readily available. Rapid track dilatation under general anesthesia, immediately followed by nephroscopy, has been a major contribution to success in renal calculus removal, resulting in considerably shortened patient and physician time.
经皮肾造瘘通道的扩张对于诸如结石或异物取出以及肾镜检查等操作至关重要。在140例患者中，采用了一种快速扩张至24F的技术。该操作仅需几分钟。事实证明，此方法安全、易于掌握，且材料易于获取。在全身麻醉下进行快速通道扩张，随后立即进行肾镜检查，这对成功取出肾结石做出了重大贡献，显著缩短了患者和医生的时间。
