What is Anderson-Hynes pyeloplasty?

Anderson-Hynes pyeloplasty is a surgical procedure designed to correct ureteropelvic junction (UPJ) obstruction, a condition where urine flow from the kidney to the ureter is blocked. The technique involves removing the obstructed segment of the renal pelvis and reconstructing the ureter to create a wider passage for urine drainage. This procedure can be performed via open surgery or minimally invasive techniques, such as laparoscopy or robotic-assisted surgery. It is typically indicated in patients experiencing symptoms such as pain, recurrent urinary tract infections, or kidney damage due to the obstruction.
