Decompression of renal cyst

Treatment of diseases: renal cysts Indication Renal cyst decompression is suitable for: 1. Simple renal cyst, which is compressed by the renal parenchyma and affects kidney function. 2. Isolated multi-atrial renal cyst. 3. Cyst around the renal pelvis, pseudocyst around the kidney with infection, resulting in urinary tract obstruction. 4. Large cysts of polycystic kidney disease oppress the renal parenchyma, causing urinary tract obstruction. Contraindications There are no absolute contraindications. However, patients with benign cysts who have severe bleeding tendency may be relatively contraindicated. Radical cysts should be treated with cancerous renal cysts. Preoperative preparation 1. Preoperative pyelography confirmed the cyst site and its anatomical relationship. 2. When the kidney capsule is combined with cancer, it is necessary to prepare for partial nephrectomy or radical nephrectomy. 3. Use antibiotics when combining infections. Surgical procedure Incision Use the 11th intercostal or lumbar oblique incision. 2. Reveal the cyst The muscles of each layer were cut in turn, and after the perirenal fascia was cut, the kidneys were separated by a finger into the perirenal fat sac. The cysts were determined according to the position of the cyst determined by preoperative renal angiography, and cysts were revealed. 3. Cut the top wall The fluid in the capsule is first aspirated, and then the cystic wall of the cyst is removed along the plane of the renal parenchyma. Carefully check the cyst cavity for abnormality, that is, fill the residual cyst wall with anhydrous ethanol cotton ball, remove it for 5-10 minutes, and fill it with pedicled perirenal fat tissue. 4. Stitching the edge of the cyst After excising the exposed wall, the bottom of the cyst is completely opened, and the edge of the capsule wall and the renal parenchyma are continuously sutured with a 3-0 absorbable line to make it heal with the surrounding tissue to achieve complete hemostasis and prevent local accumulation. liquid. 5. Suture incision After the operation, the kidney was placed in situ, and the rubber tube was drained around the kidney. If it is a simple cyst, it can also be drained. The waist incision is sutured in layers. complication 1. Intrakinal infection: mostly due to low body resistance, improper treatment during surgery, caused by perirenal blood and effusion. 2. Incision infection: The incision causes blood accumulation due to incomplete hemostasis, or infection due to surgical field contamination. 3. Peritoneal injury: less common, once it occurs, it should be repaired in time.
