What symptom does darling pelvis separate

summary

First of all, I'd like to explain to you that the "separation" in "B-ultrasound shows the separation of the renal pelvis 5mm" is the expansion of the renal pelvis. The separation of renal pelvis in normal adults is within 10 mm, but it is very uncertain for fetus. Generally, the separation of the renal pelvis in the fetus is normal within 4mm. If the separation of the renal pelvis is 5mm as shown by the B-ultrasound of the patient, it is generally detected during pregnancy. Pyelosis can often be caused by stones, tumors, blood clots or inflammatory strictures. In addition, some congenital diseases such as ureteral webs, ureteroceles and urethral valves can also be caused. Therefore, we should not be careless about the phenomenon of renal pelvis separation, we should make further observation.

What symptom does darling pelvis separate

First, ultrasound is very sensitive for the display of pyelosis in hydronephrosis, which can detect the pyelosis more than 0.5cm, and measure the thickness of renal parenchyma at the same time, so as to understand the atrophy of renal parenchyma caused by hydronephrosis. Ultrasound can find the lesions of hydronephrosis caused by tumor, stone, ureteral cyst and prostatic hyperplasia of urinary system, but for congenital ureteral stricture, inflammatory adhesions and other diseases, other imaging examinations should be combined to make diagnosis.

Second: urography can well show the renal pelvis, and for the masses in the renal pelvis area, the enhanced scan can clearly show the filling defect caused by the tumor, and can also find the local lymph nodes and other parts of the metastatic lesions. But urography is relatively expensive, so if there is no obvious clinical symptoms, we can consider it as normal physiological pyelosis.

Third: magnetic resonance imaging (MPI) is an auxiliary examination method for masses in renal pelvis separation, which is only suitable for those who are allergic to iodine contrast medium. Do urography must be done before iodine allergy test, and the best fasting examination, empty bowel gas, otherwise the examination will cause error. Special attention should be paid to the benign and malignant masses of renal pelvis separation in order to prevent renal pelvis cancer.

matters needing attention

This paper introduces several common methods of separating the renal pelvis. Or ultrasound is the best for patients, ultrasound for the diagnosis of hydronephrosis does not need to use contrast agent, no X-ray radiation, for non functional kidney can also be very good display. In addition, the scope of separation of renal pelvis should preferably include its thick diameter, long diameter and wide diameter.
