Nephrostomy catheters are prone to kinking or damage because the thin, flexible silicone tube is too vulnerable against mechanical stress even when the proximal end is carefully fixed. We developed a simple method to reinforce the outside part of a thin catheter protruding from the skin.
We treated 7 children with nephrostomy catheters or ureteral stents with a diameter of 8F or smaller. After insertion a large plastic tube was wrapped around the small catheter, and fixed to the skin and to the peripheral collection system with adhesive tape.
Handling of the catheters improved and there was less need for re-fixation.
Thin nephrostomy catheters can be effectively protected by wrapping them into a larger, outer tube after insertion.
肾造瘘导管容易发生扭结或损坏，因为即使近端固定仔细，细的柔性硅胶管也极易受到机械应力的影响。我们开发了一种简单的方法来加固从皮肤突出的细导管的外部。
我们治疗了7名使用直径为8F或更小的肾造瘘导管或输尿管支架的儿童。插入后，将一根大塑料管缠绕在小导管周围，并用胶带固定在皮肤上和外周收集系统上。
导管的操作得到改善，重新固定的需求减少。
细肾造瘘导管插入后可通过将其包裹在更大的外管中来有效保护。
