Abstract

The utility model discloses a new type of nephrostomy tube, which comprises a plurality of drainage side holes on the side wall of the cavity tube, and a closed tube body without holes on the cavity tube B, and is characterized in that: the upper port of the cavity tube A and the cavity tube The lower port of B is detachably connected, the lower port of lumen A communicates with the bladder, and the upper port of lumen B passes through human skin and is fixed outside the body. After the operation, there is no indwelling large nephrostomy tube in the patient, which reduces pain and other discomfort. After the operation, the DJ tube of the nephrostomy tube can be directly removed from the skin, which is convenient for medical operations and improves the quality of life of the patient.

Description

A new type of nephrostomy tube

technical field

The utility model belongs to the field of nephrostomy, in particular to a novel nephrostomy tube.

Background technique

In order to drain the renal pelvis and improve renal function, pyelostomy is often used in modern medical care to reduce infection of the renal pelvis and renal parenchyma, but postoperative renal pelvis may be repeatedly infected due to ostomy, affecting renal function. Using conventional nephrostomy tubes, patients with PCNL after indwelling F16-F20 (16mm-20mm) nephrostomy tubes have pain and discomfort, prolonged hospital stay, and many complications. It is also possible to achieve tubeless PCNL without indwelling a nephrostomy tube, but the disadvantage is the problem of postoperative residual stones; if the residual stones cannot be found during the operation, a second renal puncture is required for PCNL, and the routine indwelling DJ tube after PCNL should be The proximal end was placed in the renal pelvis, and the distal end was in the bladder. The DJ tube was removed through cystoscopy 1 month after the operation.

In order to prevent residual obstruction of gravel, postoperative adhesion, stenosis and obstruction of ureter. Using the "percutaneous nephrolithotomy" operation, a channel is established through skin drilling to remove stones from the kidney. The DJ tube is indwelled in the kidney, and a thicker nephrostomy tube is routinely indwelled. However, if the kidney stones are not removed, the renal channel must be re-established, which will cause great damage and greatly reduce the quality of life of the patient.

Contents of the invention

The technical task of this utility model is to provide a new type of nephrostomy tube for the deficiencies of the above-mentioned prior art, to realize the "nephrostomy DJ tube", which can directly pull out the DJ tube from the skin, because the indwelling nephrostomy tube The cavity is small, and the postoperative discomfort of the patient is small. If there are residual stones, the operation can be performed again through this passage outside the skin.

A new type of nephrostomy tube, including a plurality of drainage side holes on the side wall of the lumen A (1), and a closed body without holes on the lumen B (2), characterized in that: the lumen A (1) The upper port and the lower port of the lumen B (2) are detachably connected, the lower port of the lumen A (1) communicates with the bladder, and the upper port of the lumen B (2) passes through the human skin (4) and is fixed outside the body.

Among them, the nephrostomy tube is a silicone DJ tube with a diameter of 6-7 mm, and the upper port of the lumen B (2) is 10-20 cm away from the skin.

The beneficial effect that the utility model brings has:

1. The patient had no pain or other discomfort after indwelling a thick nephrostomy tube.

2. After the operation, the DJ tube of the nephrostomy tube can be directly removed from the skin.

3. Shorten hospital stay.

4. It can improve the quality of life of patients after surgery.

Detailed ways

Embodiments of the utility model are described in detail below in conjunction with the accompanying drawings.

A new type of nephrostomy tube, including a plurality of drainage side holes on the side wall of the lumen A (1), and a closed body without holes on the lumen B (2), characterized in that: the lumen A (1) The upper port and the lower port of the lumen B (2) are detachably connected, the lower port of the lumen A (1) communicates with the bladder, and the upper port of the lumen B (2) passes through the human skin (4) and is fixed outside the body.

Among them, the nephrostomy tube is a silicone DJ tube with a diameter of 6-7 mm, and the upper port of the lumen B (2) is 10-20 cm away from the skin.

During the operation, the lumen B (2) is indwelled outside the skin through the renal surgical channel, and there should be no side holes. Lumen A (1) is a normal DJ tube with side holes, which is indwelled into the bladder through the ureter.

If there are residual stones, a zebra guide wire can be placed through the nephrostomy DJ tube again for expansion, and a simple percutaneous nephroscopic surgery is performed without re-puncture.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.

Claims (2)

A new type of nephrostomy tube, including a plurality of drainage side holes on the side wall of the lumen A (1), and a closed body without holes on the lumen B (2), characterized in that: the lumen A (1) ) and the lower port of lumen B (2) are detachably connected, the lower port of lumen A (1) communicates with the bladder, and the upper port of lumen B (2) passes through human skin and is fixed outside the body. 2. A new type of nephrostomy tube according to claim 1, and its additional technical features are: the nephrostomy tube is a silicone DJ tube with a diameter of 6-7 mm, and the upper port of the lumen B (2) is 10 meters away from the skin. -20cm.
