calyceal ureteral anastomosis

Obstruction of the fistula of the intrarenal renal pelvis, because the stenosis is embedded in the surrounding renal parenchyma, there is no dilated renal pelvis outside the renal pelvis, only a segment of the ureter that has compression or stenosis, can not perform any kind of pyeloplasty Or Davis technology. Renal ureteropelvic anastomosis is a surgical procedure that has been used in the past. Treatment of diseases: hydronephrosis Indication Renal ureteropelvic anastomosis is suitable for: Intrarenal hydronephrosis is often caused by long-segmental stenosis below the bilateral fistula connection, or in the same type of lesion in isolated kidney. After obstruction, the high pressure of the collecting system directly affects the renal parenchyma and the renal capsule, and there is no room for the expansion of the extrarenal renal pelvis, so the renal function damage is progressive, and once diagnosed, it should be treated surgically. Some cases have failed to undergo a formal surgery other than the renal hilum, and there are more serious adhesions and fibrosis in the renal hilum area. The timing of the operation can neither wait nor perform other types of forming operations. Intrarenal hydronephrosis often complicated with renal pelvis and renal pelvis stones, and some coexisting mixed infections, the delay of surgery will increase the damage to renal function. The renal parenchyma of the lower group of the renal pelvis, which is compressed and thinned, is an ideal part of the anastomosis of the renal pelvis and the normal ureter after partial resection. Contraindications When the kidney is acutely infected, it is only necessary to first perform renal pelvis decompression drainage. After the infection is controlled, the ureteropelvic anastomosis can be performed. Otherwise, the infection can spread and the anastomotic leakage can easily lead to surgical failure. Surgical procedure 1. Expose the kidneys and free half of the kidneys below the renal hilum, including the renal hilum and the inferior pole, until the normal area of the upper ureter. Remove adhesions and connective tissue from the area. The renal capsule is removed from the kidney, and the thinnest piece of kidney tissue is excised in the subrenal renal pelvis at the partial nephrectomy to expose the infrarenal hernia. The renal parenchyma wound was sutured with silk suture to stop bleeding. The ureter was removed from the renal stenosis to the stenosis of the normal segment and fibrotic, and the incision of the renal pelvis was closed. 2. The upper ureteral incision is longitudinally cut into two lobes between the two positioning sutures to expand the anastomotic diameter, and the proximal incision of the ureter and the proximal valvular ureter adhere to the renal parenchyma. Match. After the posterior wall anastomosis is completed, the ureteral stent tube and the renal stoma tube are inserted, and then the anterior wall is sutured intermittently by the external suture method. The rubber band is drained in the operating area. The incision was sutured layer by layer.
