After ureteroscopy/nephrolithotripsy, ureteroscopy, and pelvic ureteroplasty, patients are left with a stent tube, or D-J tube, in their bodies to support the ureter and drain urine, which is usually removed 1 to 3 months after surgery. Many patients experience some uncomfortable symptoms during the period with the tube, and some of them are tormented by these symptoms, making it difficult for them to walk, and the whole family has no peace, but most of them are actually temporary and tolerable. So I think it is necessary to communicate with the patients. I have grouped these symptoms into “three major monsters” to make it easier for you to remember. The first major monster, hematuria. It is the most common. Although the mucosa of the renal pelvis, ureter and bladder is thicker and thicker than the migrating epithelium, it is the place where the urine goes, and when faced with a thick and hard tube, it is still defeated by friction (in fact, the stent tube is a biosynthetic material, soft and tough, smooth and compatible with the human body). The delicate mucosa is rich in capillaries, and bleeding is inevitable. Characteristics: Patients often have hematuria after prolonged walking, bending activities or going up and down stairs, and the hematuria will be more obvious if they drink less water. Most of the hematuria is hematuria in the second half of the process or the whole process, and sometimes you can even see small red and black blood clots or small blood flakes. ※Response: Don’t be afraid! Patients with a tube can live a normal life without problems, and they can go to the supermarket or take a walk. Even a small amount of bleeding is not a problem, as long as they drink more water and lie down to rest for half an hour, they will be clear after a few times of urination. But if the bleeding is so much that lying down and resting does not relieve it, or if the blood clot is blocked in the urethra and cannot come out, then you need to see an emergency doctor in time, so that the doctor can help you use some drugs and flushing to stop the bleeding. The second biggest monster, back pain and backache. The reason: there is a curved hook on the top of the stent tube, which is made when the material is synthesized, and the purpose is to be stuck inside the kidney to prevent the stent tube from slipping. When the patient moves or even breathes, the friction and irritation between the stent tube and the mucous membrane of the renal pelvis and upper ureter cause the patient’s back pain and discomfort. Characteristics: As with all pain, the degree of back pain varies from person to person, with some being immobilized and others being unaware of it. Some are paroxysmal and some are constant. The solution is simple: drink more water, lie down and rest, and take oral painkillers only once if necessary. The third major monster, frequent urination + small stomach pain. Causes and characteristics: There is also a curly hook under the stent tube, which is designed to be stuck in the bladder to prevent the stent tube from moving up (it is not easy to take it out if it shrinks up). Because the length of the stent tube is not as diverse as the specifications, sometimes a tube that is too long can be coiled in the bladder. Some patients still have a catheter temporarily inserted after surgery. These hooks and extra tubes will stimulate the nerve-ridden bladder triangle, and the patient will frequently feel the urge to urinate, urinate urgently, go to the toilet but not urinate anything (or just urinate some blood), and the abdomen will be sore and swollen, and the discomfort will be down, to a lesser or greater extent. Countermeasures: The same, drink more water, lie down and rest for a while. The frequency of the crime can also be used half of the anti-inflammatory pain suppository in the anus, the effect is very good. These three big demons often make waves and appear out of nowhere. Sometimes they come out individually, sometimes they work together. For example, a post-operative patient with a tube took a long walk to the supermarket and came back with back pain and blood in her urine, and she was weak when she saw blood in her urine. After careful examination, the first is to stabilize the patient and family emotions, and then a large bag of fluids infusion into the hospital bed for 2 hours, nothing happened. This is a relief. If you drink a lot of water at that time, hurry to lie down to recuperate for a while, relax the nervousness, the symptoms will soon be relieved. Of course, the strongest trick to deal with these three monsters is – pull out the D-J tube! Once the stent tube is removed, all these symptoms will disappear within a few days. However, there are some symptoms that occur with the tube that should not be ignored. High fever, renal colic, and severe persistent hematuria are all symptoms that need to be reported to the emergency room in a timely manner, and depending on the situation, the doctor will give the patient appropriate treatment. There is also a relatively special case of pregnant women with tubes. Some pregnant women have a ureteral stent tube inserted in their bodies because of small stones in the ureter, or fluid in the ureter caused by uterine pressure, and so on, and then take it out after giving birth. During this period, you should be more careful to avoid pain or infection that may affect the health of the mother and child.
