Benefits of RIRS

RIRS is a minimally invasive operation, the best among all kidney stone removal procedures, to treat challenging cases with ease. The best part of this technique is that there is no need of making any skin incisions and still the surgery is performed inside the kidney by moving up and through the urethra with the surgical instrument using fluoroscopy. Other advantages of RIRS are:

  • The rate of kidney stone removal is very high among the patients.
  • There is safe kidney stone removal.
  • As the surgery is minimally-invasive, the procedure is associated with minimal risk and quick recovery.
  • The surgery is not time-taking and there is minimum hospitalisation (from a few hours to a day) needed.
  • The operation does not cause any damage to renal tissues.
  •  In a single sitting, the patient can get rid of kidney stones. However, more than one treatment session would be required for removal of hard and brittle stones.
  • The surgery has minimal to no postoperative complications. Unlike PCNL surgery, the possibility of developing sepsis is not seen and having a drop in haemoglobin level is very less after the surgery. 

What is RIRS?

RIRS is a minimally invasive kidney stone removal technique for kidney stones treatment in Hyderabad. It is the method involving the passing of a fiberoptic endoscope through urethra to the kidney to view and operate the inside of the kidney. This fibre-optic tube is flexible and so can easily bend with the renal system and pass through the ureter and kidneys. The tube is moved into the part of the renal pelvis to help visualise the different kidney parts. Further, a thin, holmium laser fibre is passed through the endoscope to fragment the kidney stones into powdered form with thermal energy. This makes it easier for the kidney stones to be flushed out of the system with urine or else through saline irrigation.

Before RIRS Surgery

RIRS Surgery in Hyderabad is only recommended and performed on the patients after they undergo the following tests before their operation.

  1. Pre-surgical fitness test from the anaesthetist.
  2. A blood and urine test to ensure their stable health.
  3. An X-ray imaging test of the Kidneys, Ureter, and Urinary Bladder to check for stones and locate them.


Before the RIRS procedure, the urologist typically provides the following pre-operative instructions to assist the patient in getting ready for the RIRS surgery:

  • Avoid intake of blood thinners as it can lead to difficulty in clotting of blood during and after surgery. Inform the doctor about current intake of medications/supplements as well as medical conditions.
  • Give up on smoking.
  • Let the doctor know if having any allergies to anaesthesia. The doctor takes into account the patient's preferences for the type of anaesthesia to be used before the surgery.
  • On the day of the surgery, wear loose, comfortable garments. Avoid eating or drinking anything for 6-8 hours beforehand.

What does RIRS Surgery involve?

RIRS procedure

The RIRS procedure lasts for around 1-2 hours. This operation is carried out under spinal or general anaesthesia to ensure no discomfort during the procedure.

In this incision less surgery, the kidney stone surgeon in Hyderabad first places a stent in the urethra to prevent the collapse of walls of ureter. For some patients, a pre-operative DJ stenting may be done 2 weeks prior to the operation. This is important to dilate the ureter and make it easy for the urethroscope to get inside the kidneys and access the portion of the kidneys that produce urine.

Once the anaesthesia takes effect, the doctor inserts an endoscope- a flexible, long digital fibre optic tube, into the urethral canal to the ureter. To precisely place the endoscope, the doctor even uses X-rays and image screening to see real time pictures of the inside of the kidneys on an external screen. The insertion of the endoscope is done in a retrograde manner- in the direction of the kidneys.

After locating/detecting the stones, the doctor makes use of forceps to completely remove the stones or holmium laser to shatter the stones into smaller pieces without harming the surrounding organs. These pieces of kidney stones are collected in a stone basket which is later taken out after the doctor confirms that all kidney stones have been recovered. The surgery ends with removal of the endoscope and draining out of excess fluids from the kidney. The doctor may insert a urinary catheter into the urethra to reduce discomfort and difficulty in urinating. This remains for 8 to 24 hours after surgery.

The people who can get benefit from RIRS include:

  • Patients with small to medium sized kidney or ureteral stones up to a diameter of 2cm, non-opaque and hard stones, or multiple stones including the nephrocalcinosis- increased calcium levels in the kidneys.
