Preparations like shaving the private parts etc will be done on the previous day of the surgery. Pre operative DJ Stening will be done 2 weeks prior to RIRS surgery. This procedure is generally carried out under general anesthesia. On the day of the surgery the patient is expected to fast for 4-6 hours.
Post operative care
After completing the retrograde intrarenal surgery (RIRS) the patient will be brought to the recovery room where he will be under intensive care. The patient will be carrying a urine catheter for one day which is intended to reduce the pain and difficulty in urinating. After spinal anesthesia, 24 hours bed rest will be necessary.
