How to check for hydronephrosis

Hydronephrosis is a disease that causes increased pressure in the kidneys and dilation of the renal pelvis and calyces due to obstruction of urine discharge. Early diagnosis and testing are crucial to preventing kidney damage. This article will combine the hot medical topics on the Internet in the past 10 days, introduce the detection methods of hydronephrosis in detail, and provide structured data for reference.

1. Common symptoms of hydronephrosis

Symptoms of hydronephrosis may vary depending on the severity of the condition, but common manifestations include:

• lower back or abdominal pain
• Frequent urination, urgency, or difficulty urinating
• Hematuria
• Fever (when combined with infection)
• Nausea and vomiting (when severe)

2. Examination methods for hydronephrosis

The following are commonly used clinical methods to detect hydronephrosis:

3. How to choose the inspection method?

The doctor will choose the appropriate examination method based on the patient's specific situation:

• Suspected mild hydronephrosis: Ultrasound examination is preferred.
• Unknown or complicated cases: It is recommended that CT or MRI be further clarified.
• Pregnant women or children: Ultrasound or MRI is preferred to avoid radiation.
• Combined with abnormal renal function: Requires combined blood and urine tests.

4. Recent hot topics: AI-assisted diagnosis of hydronephrosis

In the past 10 days, one of the hot topics in the medical field has been the application of artificial intelligence (AI) in medical imaging. Research shows that AI algorithms can improve the early diagnosis rate of hydronephrosis and reduce missed diagnoses by analyzing ultrasound or CT images. For example, after a tertiary hospital piloted an AI-assisted system, the detection rate of hydronephrosis increased by 15%.

5. Prevention and precautions

• Get regular physical exams, especially if you have a history of urinary tract disease.
• Drink more water to reduce the risk of stone formation.
• Seek medical attention promptly when symptoms such as low back pain or hematuria occur.

Through scientific examination methods, hydronephrosis can be detected early and intervened. If you have relevant symptoms, it is recommended to go to the hospital for professional evaluation as soon as possible.
