When urinary issues like flank pain or persistent blood in urine appear, patients often delay visiting a urologist. But in many cases, early diagnosis and treatment can prevent major complications. One of the most precise procedures in modern urology is Ureterorenoscopy, commonly known as URS.

If you're dealing with kidney stones, unexplained symptoms, or urinary blockages, this blog will help you understand when URS is recommended, how it works, and what recovery looks like.

What is Ureterorenoscopy (URS)?

Ureterorenoscopy is a diagnostic and therapeutic procedure used to evaluate and treat problems inside the ureter and kidney. During the procedure, a thin, tube-like device called a ureteroscope is inserted through the urethra and bladder to reach the ureter (the duct connecting the kidney to the bladder).

It’s typically performed to remove stones or assess any blockages, growths, or bleeding sources in the urinary tract. The scope used can either be rigid or flexible, depending on the location of the problem.

Unlike open surgery, URS is a non-incisional approach, making it a preferred method for both diagnosis and treatment of many urological conditions.

When is URS Recommended?

Ureterorenoscopy is not a routine test. It is recommended in specific scenarios where other non-invasive imaging or treatments aren’t sufficient. Here are the main conditions where URS becomes necessary:

1. Kidney Stones in the Ureter

One of the most common reasons for URS is the presence of ureteric stones—especially those lodged in the middle or lower ureter. When medical therapy or shock wave lithotripsy fails, URS becomes the best option to locate and break these stones using laser energy.

2. Hematuria (Blood in Urine)

If a patient experiences unexplained hematuria, URS helps visualize the ureteral lining and detect the source—whether it’s a tumor, injury, or inflammation.

3. Suspected Tumors or Abnormal Growths

URS plays a diagnostic role in identifying ureteral tumors, polyps, or suspicious lesions. Tissue biopsies can be taken during the procedure for laboratory testing.

4. Ureteral Strictures

In cases of narrowing of the ureter (known as strictures), URS can help both in diagnosis and therapeutic dilation or laser treatment to widen the passage.

5. Blocked Urine Flow

If urine flow from the kidney to the bladder is disrupted, leading to swelling or infection, URS allows the urologist to directly assess the blockage and treat it accordingly.

URS Procedure: Step-by-Step Overview

Understanding what happens during a URS procedure can ease a lot of anxiety. Here’s how the process typically unfolds:

1. Pre-Procedure Preparation

• Patients undergo imaging tests like an ultrasound or CT scan to identify stone location or abnormalities.

• You may be advised to fast for a few hours before the procedure.

• Any blood-thinning medications are paused temporarily.

2. Anesthesia

• Most URS procedures are performed under general anesthesia.

• Some cases may involve spinal anesthesia, depending on the patient’s condition.

3. Scope Insertion

• The ureteroscope is inserted through the urethra, passed into the bladder, and then into the ureter.

• If a stone is found, the urologist uses laser energy to break it into small fragments that can be removed or pass naturally.

4. Stent Placement (If Needed)

• In some cases, a temporary DJ stent is placed in the ureter to allow smooth urine flow and reduce swelling.

• It’s removed after a few days or weeks during a follow-up visit.

Benefits of Ureterorenoscopy

Compared to older techniques or invasive surgeries, URS offers several benefits:

1. No Surgical Cuts

URS is performed using natural openings in the body. This means there are no external incisions, leading to less discomfort.

2. Precision Laser Treatment

Advanced laser urology treatment allows urologists to target even small stones or tumors precisely without harming surrounding tissues.

3. Quick Recovery

Most patients can go home the same day or after one night of observation. Recovery time is generally shorter than with open procedures.

4. High Success Rate

Especially for lower ureteric stones, URS is among the most effective treatment options available, with excellent stone clearance rates.

5. Ideal for High-Risk Patients

Patients who are unfit for open or laparoscopic surgery due to age or health conditions can safely undergo URS.

Are There Any Risks Involved?

Like any medical procedure, URS has some potential risks, although they are generally minimal:

• Mild bleeding during or after the procedure.

• Urinary tract infection (UTI) – usually prevented with post-operative antibiotics.

• Discomfort from the stent, including frequent urination or burning sensation.

• Ureteral injury or perforation (very rare).

Patients are advised to monitor symptoms and contact their urologist if they experience fever, severe pain, or inability to pass urine.

Recovery After URS Surgery

The recovery after URS is usually quick and smooth with proper post-operative care.

Common Post-Procedure Symptoms:

• Mild burning while urinating

• Pink-colored urine for 1–2 days

• Stent-related urgency or discomfort

Recovery Tips:

• Drink plenty of water to flush the urinary system.

• Avoid heavy physical activity for at least 5–7 days.

• Take medications as prescribed for pain and infection prevention.

• Avoid caffeine and alcohol until cleared by your doctor.

Stent Removal:

If a stent was placed, it will be removed in a follow-up visit, usually after 1–2 weeks. This is a minor procedure that takes only a few minutes.

How to Prevent Kidney Stones After URS?

Since stones are a recurring problem, post-procedure care is crucial to avoid repeat URS procedures. Here are some practical prevention tips:

• Stay hydrated – aim for 2.5–3 liters of water daily.

• Limit salt intake to prevent calcium buildup.

• Reduce animal protein and oxalate-rich foods like spinach, nuts, and chocolates.

• Regular follow-ups with your urologist, especially if you have a history of stones.

Patients looking for URS for kidney stones in Chennai should also discuss long-term prevention strategies tailored to their stone type.

Why Early Urology Consultation Matters

Many urinary issues that are easily treatable in the early stages become more complex if neglected. Consulting a urology doctor early ensures accurate diagnosis and appropriate treatment—whether it's lifestyle advice, medication, or procedures like URS.

Ignoring signs like flank pain, burning urination, or blood in urine can lead to infection, kidney damage, or recurring stones. So it’s always better to act early and seek timely help.

Looking for URS in Chennai?

Patients from areas like Pallikaranai, Alwarpet, and Mylapore can now access advanced URS procedures guided by experienced urologists who focus on laser urology treatment and minimally invasive care.

If you’ve been advised URS or have symptoms that could point to kidney stones or urinary obstruction, it’s important to undergo a proper evaluation by a urology specialist.

Conclusion

Ureterorenoscopy is a highly effective and safe method for diagnosing and treating many urinary tract problems, particularly ureteric stones. Its minimally invasive nature, faster recovery time, and precision make it a preferred option for both patients and doctors.

If you're dealing with ongoing urinary issues, don’t ignore the signs. Early diagnosis and intervention can save you from discomfort and future complications. Book a consultation with a urologist in Chennai and explore whether URS is the right choice for you.
