Ureteropelvic junction (UPJ) obstruction is when part of the kidney is blocked. Most often it is blocked at the renal pelvis. The kidneys are bean-shaped organs on both sides of the spine in the posterior wall of the abdominal cavity.The most important task of the kidneys is to cleanse the blood and expel the harmful substances from the body with urine.The urine produced in the kidney is transported to the urinary bladder with tubular structures called ureter.
Ureteropelvic junction (UPJ) obstruction is the obstruction of the ureter where the ureter enters the kidney.Obstruction may be congenital or may be gained later.Generally, it stems from the pressure of the vessel located in that area.This prevents the urine produced in the kidneys from passing into the urethra and passing into the bladder.As a result, the fluid pressure inside the kidney increases and after a while, renal function deterioration occurs.
The treatment of UPJ obstruction is surgery. Surgery is performed by open, laparoscopic or robotic methods.Robotic UPJobstruction surgery is performed with robotic arms which are sentinto 3-4 small incisions made to the abdominal wall. The surgeon sits in a place called the console and performs the operation using the arms of the robot.The robot arms have the ability to make maneuvers which cannot be done by human hands and to enter easily into narrow areas.Because of the small operation incision, recovery after surgery and return to normal daily life is faster.The pain felt in the postoperative period is less.
