Retrograde Intrarenal Surgery or RIRS is the surgical procedure which is performed inside the kidney using the viewing tube called fiberoptic endoscope. Surgeons implement RIRS to manage the kidney stones and remove them safely. The endoscope used in the procedure helps the surgeon to see the stones and measure its size and shape and later it is crushed or blasted using the ultrasound probe or laser probe or it can be removed later using pair of small forceps manually. RIRS provide quicker solutions to patients with kidney stones and recovery is also faster compared to other kidney stone surgeries and it also eliminates prolonged pain post-surgery.
Retrograde Intrarenal Surgery is the outpatient procedure and prescribed to patients suffering from kidney stones. This is the minimally invasive procedure and it is also prescribed to patients to treat different problems including:
Before the surgical procedure, a variety of examinations are conducted to check the actual location of the stone in the kidney. Moreover, the response of the patients to anesthesia and other health complications will be evaluated by the doctors prior to surgery. Pre-operative Dj stenting is also performed at least 2 weeks prior to the Retrograde Intrarenal Surgery. The surgery is performed under general anesthesia and patients can expect to fast for at least 6-7 hours prior to the surgery.
The Retrograde Intrarenal Surgery is performed under general anesthesia as mentioned and the surgery involves passing the endoscope through the urethra in the bladder and other parts of the kidney where the urine is collected. The scope will be move upwards gradually to reach the end of the urinary tract system and within intra-renal or kidney. Now the surgeon would remove the kidney stone using the ureteroscope, especially if the size of the kidney stone is less than 1.5cm.
As the surgeon passes the endoscope through the bladder to reach the kidney, the stones are recognized and crushed using laser beams. After the ureteroscope reaches the kidney, it is first dilated by placing the Dj stent in the affected region of the kidney at least two weeks prior to the surgery. This helps in healing faster and they can resume to their activities right from the 3rd or 4th day of the surgery.
After the procedure is successfully completed, the patients would be transferred to the recovery room where they will be monitored by the hospital staff. Urine catheter would be fixed to the urethra of the patients for one day to minimize the pain and the complications during urination. Patients are suggested to take complete rest for at least 34 hours post surgery and drink plenty of water so that they can pass out at least 3 liters of urine per day. This is helpful for keeping the kidney functioning and keep the infection at bay. If the patient is active and can heal faster, they can resume to their work soon and they will be discharged from the hospital after five days of observation and thereafter they need to take care of their health at home with assistance from family members.
Remember, if the diameter of the kidney stone is above 20mm then RIRS is not a suitable option for you to remove the kidney stone. You need to look for other options after discussing with your doctors.
