Partial resection of renal pelvis and ureteropelvic junction

This procedure was first performed in 1949 by Anderson and Hynes for pyeloplasty of the inferior vena cava and ureter. By 1962, hydronephrosis and long-term efficacy for other causes were reported. Due to the complete removal of the diseased tissue, the ureter and the renal fistula are re-synchronized, and the effect is satisfactory and widely used. Treatment of diseases: renal pelvic tumors Indication Where the renal pelvis and ureteral junction are severely stenotic, the neuromuscular tissue of this part is poorly developed, and the renal pelvis is dilated. The ureteral stricture can be used for the elderly, and the renal pelvis and ureteropelvic junction resection can be used. Surgical procedure 1. The anterior and posterior wall of the renal pelvis is completely freed, and the ureteropelvic junction and the upper ureter are clearly exposed. If the renal pelvis is too large and too swollen, first use the puncture needle to pump the renal pelvis, and then peel off after the collapse, it is easier. 2 to 3 cm away from the renal hilum, the renal pelvis ring was completely cut off, and all the stenotic and dysplastic pelvic ureteral junctions were removed, and the adjacent ureteral stricture was included, and the cut end of the normal ureter was longitudinally cuffed. 2. The upper incision of the renal pelvis was closed with a 4-0 absorbable line in two layers, and the elliptical window left was anastomosed with the enlarged sleeve end of the proximal end of the ureter. 3. Place a double "J" stent tube, make a renal stoma, and anastomize the anterior wall of the ureter.
