Is DJ Stent Necessary After RIRS?

Retrograde Intrarenal Surgery (RIRS) is one of the most sophisticated, minimally invasive techniques developed for kidney stone treatment. By using a flexible endoscope passed through the natural urinary tract, urologists can break down stones using high-precision lasers without making a single surgical cut.

However, the most common question patients ask after undergoing RIRS is: "Do I really need a DJ (Double J) stent?"

Patients are often concerned about potential discomfort, side effects, and the overall purpose of placing a temporary tube inside the urinary tract. In this blog, we evaluate the role of a DJ stent after RIRS in detail, including why it is used, its benefits, potential side effects, and whether it is always necessary.

Understanding RIRS and the DJ Stent

RIRS is an advanced endoscopic approach for managing kidney stones. During the procedure, the patient is placed under anesthesia, and a thin, flexible scope is guided through the urethra and bladder directly into the kidney. A holmium or thulium laser is then used to pulverize the stones into microscopic dust or small fragments.

What is a DJ Stent? A Double J (DJ) stent is a thin, flexible tube with coiled ends (resembling a "J") on both sides—one resting in the kidney and the other in the bladder. Its primary function is to keep the ureter open, ensuring unobstructed urine flow from the kidney to the bladder while internal tissues heal.

Why Is a DJ Stent Placed After RIRS?

While not mandatory for every single patient, a DJ stent is frequently placed after RIRS for several crucial medical reasons:

• Prevents Ureteral Swelling and Blockage: Passing endoscopic instruments and laser energy through the narrow ureter can cause temporary swelling or irritation. A DJ stent keeps the passage clear, preventing severe pain and urinary backup.
• Aids in Flushing Stone Dust: Although RIRS breaks stones into fine particles, small fragments may remain. The stent expands the ureter, allowing these fragments to pass smoothly without causing obstructions or renal colic.
• Reduces Post-Operative Pain: By guaranteeing continuous urine drainage, the stent prevents fluid pressure from building up in the kidney, minimizing post-surgical flank pain and spasms.
• Promotes Healing and Prevents Scarring: Surgical manipulation can sometimes lead to localized tissue trauma. The stent acts as a scaffold, helping the ureter heal without developing narrow scar tissue (strictures).
• Protects Kidney Function: Ensuring uninterrupted urine flow prevents hydronephrosis (kidney swelling due to trapped urine), protecting long-term renal health.

When Is a DJ Stent NOT Needed After RIRS?

Advancements in ultra-thin flexible scopes and specialized techniques—such as FANS RIRS (Suction RIRS)—have made "stentless" RIRS increasingly common. Your urologist may choose not to place a stent if:

• The stone was small, uncomplicated, and easily removed.
• There was zero swelling or trauma to the ureter during the procedure.
• All stone fragments were completely cleared or suctioned out during surgery.
• The patient has excellent baseline kidney function and low risk of post-operative complications.

Common Side Effects of a DJ Stent

While DJ stents play a vital protective role, they can cause temporary side effects as the body adjusts to the foreign object:

• Increased Urinary Frequency: The lower coil resting in the bladder can irritate the bladder lining, causing a frequent or sudden urge to urinate.
• Mild Burning Sensation: You may experience light stinging or discomfort while urinating (dysuria).
• Flank or Abdominal Discomfort: Mild aching in the side or back, particularly when urinating or changing positions, is common and easily managed with medication.
• Mild Hematuria: Seeing a light pinkish tint in your urine (blood in urine) is normal for a few days, especially after physical movement.

How Long Does a DJ Stent Stay in Place After RIRS?

The duration of stent placement depends on the complexity of your surgery and individual healing rate:

Duration

Clinical Scenario

Short-Term (5–7 Days)

Standard procedure with minimal swelling and complete stone clearance.

Moderate-Term (2–3 Weeks)

Mild ureteral swelling or small residual dust fragments remaining.

Long-Term (4–6 Weeks)

Complex cases involving large stone burdens, severe swelling, or pre-existing ureteral strictures.

Note: Stent removal is a quick, minimally invasive outpatient procedure performed using a flexible cystoscope under local anesthesia.

Tips for Managing Stent Discomfort During Recovery

If you require a DJ stent after RIRS, following these simple steps can help minimize discomfort:

1. Stay Well-Hydrated: Drink plenty of water throughout the day to keep urine diluted, reduce bladder irritation, and flush out residual dust.
2. Avoid Strenuous Activity: Refrain from heavy lifting, vigorous exercise, or intense physical exertion, as excessive movement can cause the stent to rub against the bladder wall.
3. Take Prescribed Medications: Utilize anti-spasmodics, alpha-blockers, or mild pain relievers as directed by your urologist to relieve bladder spasms.
4. Attend Scheduled Follow-Ups: Ensure you do not miss your scheduled stent removal appointment to avoid complications associated with overdue stents.

Frequently Asked Questions (FAQs)

Is DJ stent removal painful?

No. Stent removal is a quick, 5-to-10-minute outpatient procedure. A local anesthetic gel is applied to the urethra to numb the area, so patients usually feel only a slight tugging sensation as the tube is gently withdrawn.

Can I go back to work with a DJ stent?

Yes, most patients return to routine desk work within 2 to 3 days after RIRS. However, if your job involves heavy lifting or constant physical exertion, you may need to take it easy until the stent is removed.

What happens if a DJ stent is left inside for too long?

Leaving a stent in place past its intended date can lead to severe encrustation (stone mineral build-up around the stent), persistent urinary infections, ureteral damage, and chronic pain. Always adhere to your doctor's scheduled removal date.

Why does my back hurt when I urinate with a DJ stent?

When you urinate, the bladder contracts. Pressure can temporarily travel upward through the hollow stent into the kidney, causing a mild, transient ache in your side or back. Drinking plenty of fluids and taking anti-spasmodic medications helps alleviate this symptom.
