Ms. Zhang, who is in her early fifties this year, has been suffering from right-sided lumbar soreness and swelling for nearly ten years, and has not paid attention to it because she did not feel serious. Recently, she felt obvious right lumbar pain and went to the hospital for ultrasound and CT results, and the original right kidney cyst had increased in size, with a diameter of 5.0cm×6.8cm, and the local kidney parenchyma was obviously compressed and thinned. Later, she was referred to our hospital for treatment, and the doctor chose a minimally invasive surgical method for her, that is, a nephrocystectomy was performed under laparoscopy, and the top of the right kidney cyst was removed through three small holes of about 1.0cm in size, and the fluid was released, and the block recovered and was discharged after the operation, and the right lumbar pain and discomfort disappeared. Renal cysts are usually benign diseases, which can occur singly or multiply, or even simultaneously in both kidneys, and often cause kidney damage by accumulating renal parenchyma, as well as individual tumors, so when they increase to a certain extent, they need to be actively treated to terminate or slow down further damage to renal parenchyma. Previously, renal cysts could be treated by percutaneous puncture or open surgery, the former having a high recurrence rate and the latter being too invasive. In contrast, laparoscopic renal cyst debulking treatment has the characteristics of small trauma, fast recovery and low recurrence rate, and can also be performed simultaneously with laparoscopic treatment of both kidney cysts, which has the superiority that open surgery has no match. At present, laparoscopic surgery has been widely carried out in the fields of urology, general surgery and gynecology. For most diseases in urology, such as adrenal tumor, renal cyst, renal tumor, ureteral stone, pelvic ureteral junction stenosis, bladder tumor, prostate cancer, etc., laparoscopic route can be adopted for surgical treatment, which can achieve the purpose of treatment and greatly reduce the surgical trauma, enabling patients to recover faster and shorten the hospitalization time. Therefore, many open surgeries will gradually be replaced by laparoscopic surgeries, which will surely bring more benefits to patients.
