Single pigtail transplanted kidney support drainage catheter for kidney transplantation from child donors

Abstract

The invention relates to a single pigtail transplanted kidney support drainage catheter for kidney transplantation from child donors. The drainage catheter comprises a straight catheter part, a pigtail pipe part and a screw interface, wherein the screw interface can be combined with a urine drainage bag, a length of the straight catheter part is 40 cm-45 cm, is provided with tick marks, and is divided into three parts with different inner diameters, the first part is connected with the pigtail pipe part, an inner diameter of the first part is the same as an inner diameter of the pigtail pipe part, and is 2.0 mm-3.0 mm, an inner diameter of the second part is 8 mm, and an inner diameter of the third part is gradually increased to the inner diameter of the second part. The pigtail pipe partis made of a flexible material, comprises two helical curls, and is in a helical curl shape in the natural state, and the helical curl turns into a linear shape when a linear guide wire is inserted. The invention provides the support drainage catheter which is fixed firmly, is convenient for in-vitro monitoring, is convenient to remove, and is suitable for kidney transplantation from child donors.

Description

technical field

[0001] The invention relates to a medical auxiliary device, in particular to a single pig tail transplant kidney stent drainage catheter for children donated kidney transplant. Background technique

[0002] Kidney transplantation is the most effective means of treating chronic renal insufficiency uremia. The main steps of the surgical operation include the anastomosis of the donor renal artery and vein with the recipient's iliac vessels, and the anastomosis of the donor kidney ureter with the recipient's bladder. Urinary leakage and hydronephrosis caused by ureteral stenosis due to surgical technique of anastomosis of donor ureter and recipient ureter or donor ureter ischemia are serious complications after kidney transplantation. Practice has proved that indwelling stents during kidney transplantation can provide effective support after kidney transplantation and effectively drain urine from the transplanted kidney, thereby reducing such complications.

Embodiment Construction

[0017] 1. In clinical kidney transplantation, it is found that there is a significant difference in size between the children’s donor kidney and the adult’s donor kidney, so determine the diameter of the drainage catheter for the transplanted kidney stent used for the children’s donor kidney. Taking 130 cases of donated kidneys in our transplant center from January 2016 to October 2018 as the research object, they were divided into two groups according to the age of the donors, the donor group was ≥18 years old, and the recipient group was <6 years old. Kidney donor group for children. After the donor kidney was removed and trimmed, before transplantation, the long and transverse diameters of the donor kidney and the inner diameter of the ureter were measured and recorded. Among the 130 donated kidneys, there were 100 cases in the adult donated kidney group and 30 cases in the children donated kidney group. The measured values ​​of the two groups were recorded as mean ± standa...
