Since the start of laparoscopic surgery in November last year, more than 100 laparoscopic surgeries have been completed, and 17 surgical procedures have been successfully carried out, involving the treatment of 15 diseases in urology. Recently, three more difficult laparoscopic surgeries have been completed: laparoscopic pyeloplasty, renal hypoplasia fixation and complex renal cyst decortication. The successful completion of these three surgeries marks the transition of our laparoscopic technology level from destructive surgery and simple reconstructive surgery in the early stage to complex and difficult reconstructive surgery in the middle stage. Laparoscopic pyeloplasty Patient Xiao Liu, 16 years old, was found to have fluid in the left kidney due to abdominal pain and was diagnosed with stenosis of the left pelvic ureteral junction after further examination. However, laparoscopic pyeloplasty is a more difficult reconstructive surgery and must be performed by doctors with certain experience in laparoscopic surgery. After thorough preoperative preparation, the chief surgeon performed the surgery on the patient, which took 3 hours and was successfully completed. Laparoscopic renal prolapse fixation Renal prolapse is a disease in which the kidney drops more than one vertebra in standing position, causing symptoms such as back pain, hematuria and palpitations, etc. In severe cases, it is impossible to get out of bed and affects normal life and study. The patient, Ms. Li, had visited many large hospitals in Beijing for renal prolapse, and all of them suggested surgery. When she checked online that the urology department of the hospital had carried out laparoscopic surgery, she was immediately referred to our hospital, and the urology department made a detailed treatment plan for her, using the patch method of laparoscopic kidney fixation, and the patient was almost painless after the operation and was discharged from the hospital three days later. Laparoscopic surgery for complex renal cyst Lao Wang is a patient with left renal cyst who came to the Department of Urology to consult whether laparoscopic minimally invasive surgery is feasible. When the abdominal clothes were undone, it was found that the patient had five surgical scars on the abdomen and both sides of the waist, the longest one being about 30CM. After careful study of Wang’s condition, the doctor in charge skillfully designed a surgical perforation plan to avoid the scar of previous surgeries and safely completed the renal cyst debulking. Laparoscopic surgery is gradually accepted by more and more patients because of its minimally invasive, painless and fast recovery. With the continuous improvement of laparoscopic technology and the expansion of treatment scope, traditional open surgery will eventually be replaced by this minimally invasive technology.
