The diagnosis method of polycystic kidney disease is like this

As we all know, polycystic kidney disease is extremely harmful to human health. Therefore, it is particularly important to understand the symptoms and diagnosis methods of polycystic kidney disease and receive timely treatment. How is polycystic kidney disease diagnosed? In fact, there are three methods for diagnosing polycystic kidney disease: B-ultrasound, CT and magnetic resonance imaging.

1. Clinical manifestations of polycystic kidney disease include enlarged kidneys on both sides, abnormal urine, and high blood pressure, which should be suspected. A family history is more likely to indicate the disease. B-mode ultrasound, CT, and magnetic resonance imaging can reveal characteristic bilateral renal cysts, and the diagnosis can be established. In the early stage of this disease, the number of renal cysts is small and may be unilateral. If the number of renal cysts increases or extrarenal cysts appear during follow-up examinations within a few years,

The diagnosis of ADPKD can also be confirmed. In recent years, the use of DNA probes such as 3′HVR, PGP and 24-1 and gene linkage analysis has become extremely reliable for diagnosing cyst genes and can detect heterozygous family members and asymptomatic patients. The diagnosis of this disease can only be confirmed after excluding other related diseases.

2. CT scan helps rule out kidney tumors. MRI examination can better help to differentiate other cystic diseases and congenital hydronephrosis. The location, distribution, number, size, whether the cysts are connected to the renal pelvis and calyces, and the presence or absence of complications such as hypertension or recurrent urinary tract infections can help differentiate renal cystic disease.

3. In patients with mild symptoms, this disease is often misdiagnosed as simple renal cysts, solitary multilocular cysts and other multiple simple cysts. Family history and co-existing liver cysts can help with differential diagnosis.

Patients with hematuria must be differentiated from other diseases that cause hematuria, such as neoplasms and kidney stones. Attention should be paid to polycystic kidney disease complicated by stones or cyst canceration. Coagulation screening (PT, APTT and platelets) should be performed to rule out bleeding diseases. For patients with a family history of subarachnoid hemorrhage, cerebral vascular MRI can be performed.
