Unilateral nephrectomy

Renal cysts (cystofkidney) is a general term for cystic masses of varying sizes in the kidney that are not connected to the outside world. Common renal cysts can be divided into adult polycystic kidney disease, simple renal cysts, and acquired renal cysts. Generally more common on one side. Unilateral renal cystectomy can be used. Treatment of diseases: renal cysts Indication Surgery can be considered clinically if the cyst is more than 4 cm in diameter. 1. Open renal cyst decompression: The curative effect is reliable, but the surgical trauma is large and the patient has a long recovery time. 2, percutaneous renal cyst puncture sclerotherapy: small damage, but the recurrence rate is high, hardening agents often corrode the renal pelvis mucosa and leak urine. 3, posterior laparoscopy: compared with open surgery, less blood loss, postoperative pain, rapid recovery, postoperative hospital stay was significantly shortened. Contraindications (1) Cardiopulmonary complications are severe and can not tolerate surgery; (2) Infectious renal cysts; (3) Heavier local adhesions or history of retroperitoneal surgery; (4) Renal cysts with malignant tendency; (5) Patients Too obese. Preoperative preparation 1, check the vital organs of the body, especially pay attention to renal function tests (generally should include urine routine, blood urea nitrogen determination and phenol red test, etc.), to determine whether the Jianbian kidney can compensate for urinary function. 2, must preoperative pyelography, clear the two kidneys, and should be repeated to verify where the kidney is. Such as the newly discovered non-functional kidney of venous pyelography, although it can be caused by lesions, but it can also be caused by loss of contrast agent, or temporary renal artery spasm, should be identified. 3. Perform the necessary preoperative treatment. For example, kidney injury combined with shock, must be actively rescued; renal tuberculosis should be treated with anti-tuberculosis for a period of time before surgery (usually 2 weeks); urinary tract infection should be controlled; water and electrolyte disorders should be corrected; anemia and hypertension are also Should try to improve.
