Retrograde Intrarenal Surgery 
RIRS or Retrograde Intrarenal Surgery is a procedure that uses a fiberoptic endoscope for 
viewing the inside the kidney for removing stones. The recovery of RIRS is much faster 
than an open surgery. During the surgery, the stone is viewed with a scope and a laser probe 
is used to crush or evaporate the stones.
                                Overview
RIRS, also known as retrograde intrarenal surgery, is a procedure used for removing stones 
from the kidney. The procedure uses a viewing tube (called fiberoptic endoscope) through 
the urethra into the bladder inside the ureter and then into the kidney. A laser probe or 
ultrasound probe is used to crush or manipulate the stone in the kidney.
The benefits of RIRS are many and include faster recovery, quicker solution to kidney stone 
problem and minimization of prolonged pain after the surgery. Specialists who perform the 
surgery are also called urologists.
During the procedure, the stones are observed through the endoscope before removing them. 
This is an outpatient procedure suitable for patients suffering from narrowing of the kidney 
outlet, kidney stones and kidney tumours.
RIRS has many advantages owing to its 
minimally invasive technique that helps to treat:
Tumours in the kidney
Kidney stones in children
Failed attempts at treatment
Bleeding in the kidneys
Strictures in the kidney
Better clearance of kidney stones
No damage to renal tissues
Minimal bleeding
Large kidney stones that cannot be removed by lithotripsy
Compared to a traditional open surgery, RIRS uses a very advanced technique for 
the extraction of stones, be it larger than 20 mm or several small calculi. Before 
RIRS procedure, there are specific preparations to be taken.
UROLOGY TREATMENT
Before the treatment
Several X-rays and imaging tests are done to help your doctor 
determine the position of the stone/stones. Your general health 
condition is evaluated to ascertain how your body will respond to 
anaesthesia.
A thorough physical examination is done for an elaborate check 
up of your health conditions like heartbeat, pulse rate, conditions 
of the kidney and heart and other related tests. It helps your 
urology doctor to understand if you are fit to undergo the RIRS 
surgery.
Two weeks before RIRS surgery, doctors perform a pre-
operative DJ stenting.
You are required to do fasting 4-6 hours before the surgery.
How it is performed
After you are given general anaesthesia, surgeons insert an endoscope through 
the urinary tract inside the bladder. The endoscope is further placed through the 
urethra into the parts of the kidney where the urine collects.
The scope is moved upwards through the urinary tract system and inside the 
intra-renal or within the kidney. There aren’t any incisions required in the 
procedure.
Uteroscope is used to enter it through the bladder, but before the procedure the 
scope is dilated by placing a Dj stenting in the kidney a couple of weeks before 
the surgery.
The uterescope inserted helps to extract kidney stones (maximum of 1.5cm in 
size) easily. The stones are easily identified by the scope when passing it into 
the kidney through the bladder. The stones are then blasted by using laser rays 
or plucked by a Urology basket.
After RIRS procedure, double Dj stent is put inside for smooth drainage 
from the ureter and the kidney.
Since no cuts are done, there is no need requirement to close them either.
Recovery
After the RIRS procedure, the patient is taken to the recovery 
room where a urine catheter is placed in the urethra to help in 
drainage and minimize pain. The patient is instructed to rest 24 
hours after receiving spinal anaesthesia and drink 2.5 litres of 
water to help keep infections away.
Patients are usually discharged the day after the surgery if they 
recover quickly. The urologist, however, wants to check the 
patient after a week of the procedure. Listening to the doctor’s 
advices related to post-care surgery helps in quicker recovery of 
RIRS procedure. There is minimal bleeding involved, faster 
recovery and quicker extraction of stone without any problem.
