How long can pyonephrosis live?

summary

Pyonephrosis is a serious suppurative infection of the kidney. The renal parenchyma is extensively destroyed, and a large number of necrotic tissues form a huge pyonephrosis cavity with the kidney. It can be caused by the development of pyogenic infection of renal cortex, or by urinary root obstruction and infection in the development of kidney stones, pyelonephritis, renal tuberculosis, hydronephrosis and other diseases. The pathology showed that the renal tissue was seriously damaged and the kidney was filled with a lot of pus. The clinical manifestations may include the symptoms of systemic infection and poisoning, such as fever and weakness in the acute phase, low fever, emaciation, anemia in the chronic phase, and pain in the renal area, percussion pain in the renal area, enlargement of the kidney, increased white blood cells and left shift of the nucleus in the blood test. The characteristic manifestation is purulent urine, which can be found by naked eye and microscope. Let me share with you how long the pyonephrosis can live?.

How long can pyonephrosis live?

First, how long the pyonephrosis can live is related to the patient's condition. Based on the pathological changes of renal carbuncle, the renal tissue is extensively destroyed, and the kidney is filled with pus, forming a huge pus cavity. Ultrasound showed that it should be a fluid filled cystic structure, surrounded by renal capsule, forming a nearly circular outline, forming a clear boundary with the surrounding area, while the cystic area was anechoic and liquid dark area. The dark area may be different according to the degree of lesion, that is, due to the different degree of liquefaction, a small amount of incompletely damaged tissue can be seen in some areas, or the purulent material is completely liquefied, There are different forms of moderate echo. The quality of sound transmission in the pus cavity is also affected by the state of purulent substances.

Second, after pyonectomy, there is the possibility of incision infection, because the surgical incision is very easy to be contaminated, but the incision full-thickness infection is often due to improper operation during the operation. When the diseased kidney is free, the highly swollen pyonephrosis will rupture, resulting in pus contamination of the entire surgical wound. Although antibiotic saline is used to repeatedly wash the surgical wound during the operation, and drainage tube is placed for drainage, It is difficult to avoid full-thickness wound infection by actively strengthening anti infection treatment and keeping drainage tube unobstructed after operation. Moreover, it is not easy to find early postoperative wound infection, which is from deep infection to shallow infection. In addition, the elderly patients have strong tolerance and no complaints. By the time of discovery, the whole incision has been purulent infection, which leads to the need to separate the whole incision drainage and gradually remove all sutures, Long term dressing change can promote the growth and healing of the incision, which not only makes the patients suffer physically, but also increases the medical costs of the patients.

Third: recall the course of the operation. In the operation, the pus in the swollen pyonephrosis was aspirated and decompressed first, so as to avoid the chance of breaking the pyonephrosis when separating the pyonephrosis and causing the pus to contaminate the whole surgical wound. After the operation, the same treatment was taken, and the incision of the patients was completely healed without infection. Therefore, the author believes that the purulent fluid must be prevented from contaminating the whole surgical wound during pyonectomy, otherwise it will lead to full-thickness infection of incision after operation.

matters needing attention

1. The contour and shape of the affected kidney disappeared. 2. The renal area is filled with a large cystic structure, in which there is no renal structure. 3. The cysts are isolated structures and have nothing to do with the surrounding organs. 4. Cystic diseases of liver, gallbladder, spleen, pancreas and their adjacent organs and tissues should be excluded.
