Nephrostomy tubes occasionally are resistant to extraction. During the last 7 years 3 such patients with entrapped Malecot nephrostomy tubes have been treated successfully at our university. The entrapped nephrostomy tubes were removed by endoscopically incising an anchoring tissue bridge that had grown over a flange. A small endoscope was easily advanced through the lumen of the entrapped catheter to allow for adequate visualization and electrocautery of the anchoring tissue bridge. With this method an entrapped Malecot nephrostomy tube may be removed intact without significant injury to the renal parenchyma. Malecot nephrostomy tubes should be used with caution for long-term drainage of small intrarenal pelves.
肾造瘘管有时难以拔除。在过去7年中，我校成功治疗了3例带有嵌顿的马勒科特肾造瘘管的患者。通过在内窥镜下切开在凸缘上生长的锚定组织桥来取出嵌顿的肾造瘘管。一个小型内窥镜很容易通过嵌顿导管的管腔推进，以便对锚定组织桥进行充分的可视化和电灼。用这种方法，可以完整地取出嵌顿的马勒科特肾造瘘管，而不会对肾实质造成明显损伤。对于小肾盏的长期引流，应谨慎使用马勒科特肾造瘘管。
