Why USG Guided Intervention – Nephrostomy is Needed

A USG guided intervention – nephrostomy is required in patients where urinary obstruction causes swelling or infection of the kidney. This obstruction often results from kidney stones, ureteric tumors, pelvic mass, or post-surgical complications. Without timely drainage, the backflow of urine can damage kidney tissues and lead to renal failure.

By using USG-guided nephrostomy, radiologists can avoid major open surgery. The ultrasound guidance helps in locating the exact obstruction point, minimizing complications such as bleeding or damage to nearby structures. The procedure also provides a bridge for further treatments, such as stone removal, stent placement, or reconstructive urological surgery.

Typical indications for ultrasound-guided nephrostomy include:

1. Acute urinary obstruction

2. Infected hydronephrosis

3. Post-transplant kidney obstruction

4. Diagnostic access to kidney collecting system

Benefits of USG Guided Nephrostomy

USG guided intervention – nephrostomy provides several important benefits, making it the preferred choice for urologists and radiologists.

1. Minimally invasive: No large incision is required, allowing faster recovery.

2. Real-time precision: With ultrasound guidance, the catheter is positioned precisely in the renal pelvis.

3. Reduced risk: The use of USG imaging eliminates radiation exposure and ensures lower complication rates.

4. Immediate symptom relief: Patients experience rapid reduction in discomfort and hydronephrosis pressure.

5. Short hospital stay: Most patients can resume normal activity within a few days.

This technique is particularly beneficial for patients who are critically ill or not fit for open surgery. The use of USG guided percutaneous nephrostomy has revolutionized urinary drainage management, improving outcomes and preserving kidney function.

How the Procedure is Performed

The USG guided intervention – nephrostomy is performed under local anesthesia in a sterile USG suite. The patient lies prone or slightly oblique on the examination table, depending on the kidney’s position. The radiologist uses a high-frequency ultrasound probe to visualize renal calyces and select a suitable entry site.

After cleaning and numbing the area, a fine needle is guided into the renal pelvis using real-time ultrasound guidance. Once the position is verified, a guidewire is inserted, and the tract is dilated to introduce the nephrostomy catheter. The tube is then secured and connected to a drainage bag. The entire procedure usually takes 30–45 minutes.

Post-procedure care includes monitoring urine output, checking for any leakage, and performing follow-up ultrasound scan to ensure proper tube position. Patients are advised to maintain hygiene around the insertion site and report any discomfort or blockage.

Typical parameters evaluated before performing the procedure include:

1. Kidney size and cortical thickness

2. Site of obstruction and hydronephrosis degree

3. Hemoglobin and coagulation profile

4. Ultrasonographic findings of renal pelvis distension

Key Points and Aftercare

1. USG guided intervention – nephrostomy is safe, effective, and offers immediate relief from urinary blockages.

2. Regular catheter maintenance and aseptic dressing prevent infection.

3. Follow-up imaging helps confirm successful drainage and kidney recovery.

4. The nephrostomy tube can later be used for further interventions such as antegrade ureteric stenting.

Patients who undergo ultrasound-guided percutaneous nephrostomy often report improved quality of life, reduced pain, and better kidney preservation outcomes.
