Ureteral nephroplasty, also known as nephroureteral junction arthroplasty, is used primarily to address the phenomenon of ectopic vessels in the junction of the patient's renal pelvis with the ureter. The operation mode adopts Y-V forming operation of the connecting part of the renal pelvis and the ureter to separate the connecting part of the renal pelvis and the ureter, and the operation mode should be noted that the external surface of the connecting part is normal and still has narrow in practice, and physiological saline can be injected into the renal pelvis to observe whether the connecting part can be emptied. When the renal pelvis is unable to empty, the upper ureter segment below the ureteral junction should be longitudinally incised, and probed upward with a probe to encounter a blockage at the ureteral junction. The incision is lengthened upward and the Y-shape cuts through the renal pelvis revealing and resecting the fibromuscular ring of the ureteral junction of the renal pelvis. The posterior wall muscle layer of the renal pelvis and ureter was intermittently sutured with 4-0 chromium-made intestinal lines. New small mushroom catheters and plastic tubes were introduced through the renal parenchymal incision into the renal pelvis and ureter, respectively, to make a pyogenic fistula. Finally, the tip of the triangle valve is pulled to the ureter for suturing to form a V shape, and the incision is sutured according to layers after the cigarette is placed at the renal pelvis for drainage.
