A few days ago, Zhang inadvertently learned that he had polycystic kidney during a physical examination, but did not take the disease too seriously, he felt that the polycystic kidney does not feel anything and does not affect life, so he put off seeing the doctor again and again. The treatment of disease is like a battlefield, know yourself and your enemy, a hundred battles will not be lost. In fact, only by clearly understanding the condition and treatment can we “win” in the treatment. So, how should patients “manage” their polycystic kidney well? What is polycystic kidney? Polycystic kidney patients have obvious family history, with congenital heredity, many people will be found after the onset of the disease in their family members, and even the offspring children also suffer from this disease. It is very rare that the disease is not inherited from parents and is caused by genetic mutation. Polycystic kidney is a cyst in the kidney parenchyma, which looks like a pile of ripe grapes from the outside of the kidney. After the onset of the disease, many thin-walled spherical cysts can be seen in the kidney, usually ranging from a few millimeters to a few centimeters in diameter and containing bright yellow fluid, which becomes bloody when it encounters infection or trauma. With age the cysts also gradually increase in size and contribute to the gradual enlargement of the kidney, damaging the renal parenchyma, leading to renal insufficiency in severe cases and eventually forming uremia. In treatment, most of them are more severe patients. Their common feature is to focus their attention on the disease, concentrating on how they can be cured, what drugs are most suitable, whether their condition will worsen, what to do in the future and a series of worries. In fact, such worries are not necessary. Patients who are emotionally ill and psychologically overburdened, while neglecting diet and mental regulation, will have a negative impact on disease control. Therefore, patients should first recognize the disease and eliminate such unnecessary worries! Patients must be checked at least twice a year Patients with polycystic kidney must carry out regular checks on the development of cysts in the kidney, at least twice a year, with the main items being urine routine, kidney ultrasound and kidney function measurement. Conducting regular checkups can not only keep track of the condition, but also prevent patients from having bad emotions that are not conducive to improving their condition and working at ease. At the same time, it is important to detect and treat other diseases that can easily cause kidney damage, such as hypertension disease, diabetes, urinary tract infection and stones. If patients with large cysts have not yet taken any treatment, they should pay more attention to increase the number of checkups and refrain from strenuous exercise to prevent cyst rupture. Prevention of kidney function damage is crucial For patients with polycystic kidney, whether, when and how to treat it is a problem that bothers patients. There is no effective way to completely cure the disease, but one should know what level of cysts should be treated by intervention. In general, clinically, we take surgical treatment for cysts over 5 cm or multiple cysts that may further develop and affect kidney function. Currently, laparoscopic cyst decompression has become the “gold standard” for the surgical treatment of renal cysts. This procedure not only achieves the same results as open surgery, but also has less damage and faster recovery. Surgery cannot change the already formed kidney damage, but can only control the further development of kidney damage. For patients with polycystic kidney, it is recommended to frequently review the lesions of bilateral kidneys, test kidney function, and treat new further enlarged cysts if they occur. In addition, patients with polycystic kidney should pay attention to the damage of the kidney by diet and medication.
