In the outpatient clinic, we often encounter patients with this question: Doctor, I never have pain, how can I have kidney stones? This question is almost all kidney stone patients, patients have a simple habit of thinking, that is, pain is sick, no pain should not have physical problems. However, the doctor’s answer may make you lose your eyesight: the disease is more terrible without pain! Toothache, do not want to die; appendicitis pain, you can also immediately seek medical attention; then what about the tumor? What about tumors? What about tumors, or uremia, or kidney stones? These diseases often do not have pain in the early stages, but when you find pain, most of them are already advanced, there is no possibility of cure. So question one, no pain does not mean no disease, pain does not mean serious disease. Then question two came, why kidney stones do not hurt it, many patients who have had urinary tract stones are painful to death ah? This, the old Chinese medicine ancestors have long been summarized, pain is not pass. Western medicine is the same reason. Painful urinary stones, often small diameter, easy to fall out of the kidneys, in the ureteral area causing obstruction, this obstruction is temporary, but also most of the incomplete, and will cause spasms in the ureter, the urine produced by the kidneys can not be discharged, the ureter is not smooth, so it produces pain. Kidney stones that are not painful are due to the fact that the site of stone production is in the lower calyces of the kidneys. Or although it is in the upper calyx of the kidney, it is surrounded by surrounding tissues, or due to bacterial action, it is adhered to the mucous membrane of the kidney. So that the kidney stone will not move or fall out, and gradually grow slowly until it affects the whole kidney. However, as the kidney stone grows without causing obstruction, the urinary tract is open for urination, so it does not cause pain. Painful urinary tract stones, indicating that the location of the stone is moving, mostly down the ureter in the downward discharge, so often after severe colic, to the hospital, but instead of the stones themselves out, no more. This is what causes many patients to misunderstand the doctor, thinking that the doctor misdiagnosed, or the doctor did not seriously find out the cause of the patient’s colic. The doctor is really wrong, the disease is developing, this time, that time, you are in a hospital in the pain of death, nausea, vomiting, but to another hospital is said to be fine, how can this be convincing? Stones can fall out on their own, so sometimes you’ve really wronged your doctor. Since, the pain of the stone is an indication that the stone is moving, and it is even possible that the stone will be discharged by itself, so you don’t have to be anxious, and you don’t have to scold the doctor for not knowing the patient’s pain, but you should be happy with the pain, because it is possible that the stone will be discharged by itself, and you will have saved a sum of money or a possible surgery.
