RIRS, or Retrograde Intrarenal Surgery, is an advanced minimally invasive procedure used to treat kidney stones located inside the kidney. Kidney stones can cause severe pain, urinary obstruction, and infections if not treated properly. RIRS allows doctors to access the kidney through the natural urinary passage without making any external incision. For advanced stone management and expert care, many patients seek RIRS treatment in Mumbai under the guidance of Dr. Shashank Sharma, a highly experienced Consultant Urologist specializing in modern endoscopic and laser-based kidney stone treatments.
RIRS (Retrograde Intrarenal Surgery) is a modern endoscopic procedure used to treat stones located within the kidney. The procedure involves using a flexible instrument called a flexible ureteroscope that is passed through the urethra, bladder, and ureter to reach the kidney.
Once the stone is identified, a laser fiber is used to break the stone into tiny fragments. These fragments either pass naturally through urine or are removed using small instruments.
RIRS is widely used for small to medium-sized kidney stones and is especially beneficial for patients who want a treatment option that does not involve cuts or incisions.
RIRS is recommended when kidney stones cause symptoms or when they cannot pass naturally.
Small to Medium Kidney Stones:
RIRS is ideal for stones usually smaller than 2 cm located inside the kidney.
Persistent Pain:
Kidney stones can cause severe flank pain that requires medical treatment.
Failure of Medication:
If stones do not pass with medicines and hydration, RIRS may be advised.
Multiple Kidney Stones:
Patients with multiple stones inside the kidney may benefit from this procedure.
Difficult Stone Location:
Stones located in areas of the kidney that are difficult to reach with other methods can be treated using RIRS.
Recurrent Urinary Infections:
Kidney stones may lead to repeated infections in the urinary tract.
Timely RIRS treatment helps prevent complications and improves overall kidney health.
No External Incisions:
The procedure is performed through the natural urinary passage, avoiding cuts or scars.
Effective Stone Removal:
Laser technology ensures accurate fragmentation of stones.
Preserves Kidney Function:
Removing stones early helps prevent kidney damage.
Reduced Pain and Discomfort:
The minimally invasive approach reduces post-procedure pain.
Lower Risk of Complications:
Modern technology ensures safer treatment outcomes.
Quick Recovery:
Patients usually recover faster compared to traditional surgical procedures.
The approach to RIRS treatment in Mumbai depends on the size, number, and location of the kidney stones. Dr. Shashank Sharma performs RIRS using advanced flexible ureteroscopes and laser technology for precise stone removal.
Before the procedure, a detailed assessment is conducted to evaluate the stone and kidney condition. Diagnostic tests may include:
CT scan to determine the exact size and location of the stone
Ultrasound of the kidneys and urinary tract
X-ray imaging if required
Blood tests to assess kidney function
Urine tests to detect infection
RIRS is usually performed under general or spinal anesthesia to ensure patient comfort.
A flexible ureteroscope is inserted through the urethra and bladder to reach the kidney.
The doctor identifies the stone using a camera attached to the ureteroscope.
A laser fiber is used to break the stone into tiny fragments.
Some fragments may be removed using special instruments, while others pass naturally through urine.
In certain cases, a temporary ureteral stent may be placed to ensure proper urine flow during healing.
The procedure generally takes 45 to 90 minutes, depending on the size and number of stones.
RIRS is a minimally invasive procedure, so recovery is usually quick and comfortable.
Most patients are discharged within 24 hours after the procedure. Mild symptoms such as burning during urination, slight blood in urine, or mild discomfort may occur for a few days.
Patients are usually advised to:
Drink plenty of water to flush out stone fragments
Take prescribed medications to prevent infection
Avoid strenuous physical activities for a few days
Attend follow-up visits to monitor recovery
If a ureteral stent is placed, it is usually removed after 1–2 weeks.
RIRS offers several advantages for treating kidney stones.
Minimally Invasive Procedure:
No surgical cuts or incisions are required.
High Precision Laser Technology:
Laser fragmentation ensures accurate stone treatment.
Short Hospital Stay:
Most patients can go home the same day or within 24 hours.
Faster Recovery:
Patients can resume normal activities within a few days.
Safe and Effective Treatment:
RIRS has a high success rate for small to medium-sized kidney stones.
Minimal Scarring:
Since there are no incisions, there are no visible scars.
Experienced Urologist:
Dr. Shashank Sharma has more than 12 years of experience in advanced urological surgeries and kidney stone treatment.
Expertise in Laser Stone Surgery:
Highly skilled in RIRS, URSL, PCNL, and laser lithotripsy procedures.
Advanced Medical Technology:
Uses modern flexible ureteroscopes and laser systems for precise treatment.
Patient-Centered Care:
Provides customized treatment plans based on each patient’s condition.
Minimally Invasive Approach:
Focuses on treatments that ensure minimal discomfort and faster recovery.
Comprehensive Follow-up Care:
Ensures long-term kidney health and prevention of stone recurrence.
Yes, RIRS is considered a safe and minimally invasive procedure for treating kidney stones with a high success rate.
The procedure usually takes 45 to 90 minutes, depending on the number and size of the stones.
Most patients are discharged within 24 hours, although some may go home the same day.
In some cases, a temporary ureteral stent may be placed to help urine flow and aid healing.
Yes, kidney stones can recur. Drinking enough water, maintaining a healthy diet, and regular medical check-ups can help reduce the risk.
