How to diagnose renal cyst

summary

A colleague in the company suddenly asked for leave for several days, but I haven't seen anyone recently. Later, I learned that he was suffering from renal cyst. Now his life is a bit troublesome and he doesn't have much energy to work, so he went to the hospital for treatment. Now let's understand how to diagnose renal cyst.

How to diagnose renal cyst

First, we can know the number, size and wall of cyst. It can be differentiated from renal parenchymal mass and is the first choice. The typical B-ultrasound findings are that the lesion area is anechoic, the cyst wall is smooth, and the boundary is clear; when the cyst wall shows irregular echo or limited echo enhancement, we should be alert to malignant change; when secondary infection occurs, the cyst wall is thickened, the lesion area has fine echo, and the echo is enhanced when there is hemorrhage in the cyst. When imaging showed multiple cysts, it should be distinguished from multilocular cysts and polycystic kidney.

Second, intravenous pyelography (IVP) can show the degree of cyst compression on renal parenchyma, and can be differentiated from hydronephrosis. CT is valuable for those who can not be determined by B-ultrasound examination. The cyst with hemorrhage, infection and malignant transformation presents heterogeneity. CT value increases. When CT shows the characteristics of cyst, cyst puncture is unnecessary. As shown by urography, the disease is almost always bilateral, and the distort of diffuse calyces and pelvis has become its rule. Polycystic kidney is often accompanied by renal dysfunction and hypertension, while renal cysts are not.

Third: it is a space occupying lesion, but it is easy to occur in the deep part, resulting in more obvious calyceal curvature. Hematuria is common, but cyst is not seen. When the renal parenchymal tumor pressed on the psoas major muscle, the edge of the muscle could not be seen on the abdominal plain film, while the cyst was still visible. Evidence of metastasis (such as weight loss, fatigue, supraclavicular lymphadenopathy, chest X-ray showed metastatic nodules), polycythemia, hypercalcemia, and accelerated ESR all suggested cancer.

matters needing attention

To confirm whether it is a renal cyst, there is no way to determine if we do not go to the hospital for relevant detailed examination. We hope that patients find their own condition, do not blindly use drugs themselves, and do not delay the disease, but go to the hospital for treatment as soon as possible, so as to recover as soon as possible.
