Master Zhang, who lives in Huangpu District, Shanghai, is in his sixties. Although he is now retired, he is busy with his grandchildren and attending senior citizens’ college, so he is living a very full life. However, recently he fell ill, repeatedly high fever, as well as back pain, anti-inflammatory drugs or no improvement, very uncomfortable. He rushed to Shanghai Ninth People’s Hospital for a checkup and was seen by Jiang Yueqing, a specialist in the treatment of hydronephrosis and kidney stones. Director Jiang told Master Zhang that his kidney was blocked by a stone, and there was a lot of water in the kidney, and now there was an infection, turning it into a “stinky beach”! Master Zhang remembered that before he retired, he had gone to the hospital to see a doctor because of kidney stones, and after examination, he found that the size of the stones was very small, so he was treated by means of medication to remove the stones. Later, because he was busy at work and did not have any discomfort, he did not follow the doctor’s orders to review, the results developed to such a serious degree today. Because of the seriousness of Master Zhang’s condition, after careful examination, Director Jiang believed that Master Zhang needed immediate drainage so that the flow of urine could be restored as soon as possible, supplemented by a combination of effective antibiotics and plenty of water to effectively control the urinary tract infection. During the surgery, Director Jiang found that Master Zhang’s urine had turned white like pus and was also very sticky. The good thing is that after the corresponding comprehensive treatment, Master Zhang was finally cured and discharged from the hospital. Master Zhang is a very typical patient with urinary stones combined with severe infection. Urinary stones are a common and frequent disease, but since the size and location of stones are different for each patient, the choice of treatment may not be the same. For stones that are smaller in size and have a greater chance of being expelled from the body on their own, drug de-stoning treatment can be tried. However, in addition to drinking the right amount of water and taking lithotripsy medication, you should also pay close attention to each urination to see if there is a foreign body. Since stones that can be discharged on their own are usually very small and may not be clearly distinguished by the naked eye, it is especially important to review them after the drug treatment. Doctors can confirm whether the stones are discharged from the body and whether they are still a threat to the patient’s health through urine routine, ultrasound, CT and other tests. However, some patients, like Master Zhang, feel nothing uncomfortable after taking lithotripsy medication for a period of time, or they don’t review it for various reasons. This is very dangerous because if the stones are not expelled from the body, they may continue to block the urine outlet in the body, causing hydronephrosis, damaging kidney function, or even causing pus in the kidneys like Master Zhang, which can lead to urogenic sepsis and infectious shock in serious cases, endangering the patient’s life. In addition, because of the high recurrence of urinary stones, for people who have a history of urinary stones, it is generally recommended to have at least one to two ultrasound examinations every year to eliminate small stones in the bud and prevent the occurrence of hydronephrosis, and never let one of the most important organs in our body, the kidney, become a “stinky beach”.
