Renal Radiology Treatment and Follow-up

Nephrology focuses on diagnosing and treating kidney diseases. The kidneys filter waste, balance fluids, regulate blood pressure, and manage acute and chronic conditions.

Renal Radiology Treatment includes image-guided procedures and follow-up imaging used to support the diagnosis and management of kidney and urinary system conditions. Renal radiology is not a disease itself. It is a medical field that helps evaluate and, in selected cases, treat kidney problems using imaging methods such as ultrasound, CT, MRI, Doppler ultrasound and fluoroscopy.

At Liv Hospital, renal radiology treatment and follow-up are planned with nephrology, urology and radiology teams working together. The goal is to choose the safest imaging-guided approach, monitor treatment response and support a clear care plan for each patient.

How Renal Radiology Supports Treatment

Renal radiology can help guide minimally invasive procedures without the need for open surgery in selected patients. Imaging allows the medical team to see the target area more clearly and reach it with greater precision.

Image-guided care may be used for:

• Renal artery narrowing
• Kidney bleeding
• Selected kidney tumors or masses
• Blocked urine drainage
• Kidney biopsy guidance
• Follow-up after treatment
• Transplant kidney monitoring
• Stone-related obstruction

The exact procedure depends on the diagnosis, kidney function, symptoms, general health and treatment goals.

Renal Angioplasty and Stenting

Renal angioplasty and stenting may be considered when a narrowed renal artery affects kidney blood flow or contributes to difficult-to-control blood pressure in selected patients. During the procedure, a thin catheter is guided into the narrowed blood vessel using imaging. A small balloon may be inflated to widen the narrowed area, and a stent may be placed to help keep the vessel open.

This treatment is not suitable for every patient with renal artery narrowing. The decision depends on blood pressure pattern, kidney function, imaging results, overall vascular health and specialist evaluation.

Embolization for Bleeding or Selected Kidney Masses

Embolization is an image-guided procedure used to block blood flow to a specific vessel. In kidney care, it may be considered for certain bleeding problems, trauma-related bleeding, biopsy-related bleeding or selected kidney masses such as angiomyolipoma.

During embolization, a catheter is guided to the target vessel. Small materials such as coils, particles or other embolic agents may be used to reduce or stop blood flow in that area. The aim is to control bleeding or reduce blood supply to the selected abnormal tissue while protecting as much healthy kidney tissue as possible.

Ablation for Selected Kidney Masses

Ablation may be used in selected small kidney tumors or kidney masses, especially when surgery is not the preferred option. This procedure uses imaging guidance to place a needle-like probe into the target area.

Different ablation methods may use heat or cold energy to treat abnormal tissue. The most suitable method depends on tumor size, location, patient age, general health, kidney function and specialist decision.

Ablation requires careful follow-up because imaging is needed after treatment to check the treated area and monitor for recurrence or incomplete response.

Drainage Procedures and Nephrostomy

A nephrostomy is an image-guided drainage procedure used when urine cannot drain properly from the kidney to the bladder. This may happen because of a stone, tumor, narrowing, infection-related obstruction or another blockage.

During the procedure, a thin tube is placed through the skin into the kidney’s collecting system to drain urine. The urine usually flows into an external drainage bag. This can help relieve pressure, support infection control and protect kidney function while the underlying cause is treated.

The tube may be temporary or may need to stay longer depending on the reason for the blockage.

Image-Guided Kidney Biopsy

Renal radiology also supports kidney biopsy by helping guide the needle to the correct area. Ultrasound or CT guidance can help improve precision and reduce avoidable risk during the procedure.

A kidney biopsy may be needed when blood tests, urine tests and imaging do not fully explain kidney disease. The tissue sample can help diagnose conditions such as glomerulonephritis, autoimmune kidney disease, unexplained protein leakage or transplant-related concerns.

After biopsy, patients are monitored for bleeding, pain, blood pressure changes and urine color changes.

Post-Procedure Recovery

Recovery depends on the type of renal radiology procedure. Some patients may go home the same day, while others may need hospital observation. After catheter-based procedures, patients may need to rest and avoid heavy activity for a short period to reduce bleeding risk at the puncture site.

Post-procedure care may include:

• Vital sign monitoring
• Pain and comfort assessment
• Puncture site control
• Urine output tracking
• Blood tests when needed
• Infection sign monitoring
• Hydration guidance when appropriate
• Activity restrictions based on the procedure

Patients should follow the care team’s instructions about wound care, medication use, physical activity and follow-up appointments.

Follow-up Imaging

Follow-up imaging is an important part of renal radiology care. It helps doctors understand whether the treatment worked as expected and whether further care is needed.

Follow-up may include:

• Doppler ultrasound after stenting
• CT or MRI after tumor ablation
• Ultrasound after nephrostomy placement
• Imaging for kidney stone passage or obstruction
• Transplant kidney monitoring
• Repeat imaging for cysts or masses
• Biopsy-related follow-up when needed

The timing of follow-up imaging depends on the condition, procedure type and patient safety.

Safety and Contrast Planning

Some renal radiology procedures may require contrast material or fluoroscopy. Before contrast-enhanced imaging or catheter-based treatment, doctors may check kidney function, allergy history, medications and hydration status.

Patients with reduced kidney function, diabetes, dehydration or previous contrast reaction may need special planning. In some cases, the care team may choose ultrasound, non-contrast imaging or alternative techniques to improve safety.

When to Contact the Care Team After Treatment

Patients should contact the medical team if they notice symptoms that may suggest bleeding, infection, obstruction or procedure-related concerns.

Warning signs may include:

• Fever or chills
• Increasing pain
• Redness or discharge at the puncture site
• Bleeding that does not stop
• Dizziness or fainting
• Shortness of breath
• Reduced urine output
• Blood in urine that worsens
• Nephrostomy tube blockage or leakage
• Severe flank pain

Early communication helps the team respond before complications become more difficult to manage.

Why Choose Liv Hospital?

Liv Hospital offers a comprehensive approach to Renal Radiology Treatment with advanced imaging support, interventional radiology experience and coordinated care between nephrology, urology and radiology teams. Since kidney problems may involve stones, obstruction, tumors, bleeding, vascular disease or transplant-related concerns, multidisciplinary evaluation is important.

With patient-centered care, Liv Hospital helps patients understand their imaging results, treatment options and follow-up plan clearly.
