There are two main methods of surgical treatment for prostate enlargement, the first is open surgery, which requires an incision about 300px long in the lower abdomen, and to cut open the bladder and then remove the enlarged prostate tissue, which is very traumatic and bleeds a lot, and almost every patient needs a blood transfusion, and patients are in great pain after surgery due to bladder irritation symptoms, and most take 2 weeks to be discharged. The second is transurethral resection of the prostate (TURP), a procedure that removes the enlarged prostate tissue through the urethra by means of a special electroscope, without the need for an incision in the stomach. The procedure is very difficult because of the small field of view and inconvenience, and also there is often post-operative bleeding, which even requires a second operation to stop the bleeding. However, with the continuous updating of equipment and the emergence of imaging surveillance systems, the images are captured through the camera on the electrosurgery scope and displayed on the monitor with several times magnification, greatly improving the clarity of the images, and the speed, efficacy and safety of the surgery have also progressed by leaps and bounds, and TURP has rapidly replaced traditional open surgery. At present, patients usually do not need blood transfusion and can eat normally the next day, and can be discharged within one week after surgery, and the hospital stay and recovery time are also greatly shortened, and many elderly and frail patients are also able to perform the procedure. At present, our department has several sets of electrosurgery scopes equipped with imported high brightness xenon light source and high definition camera equipment, together with more than 30 years of experience in performing this surgery and a group of high level surgeons, a large number of patients with high risk prostate enlargement have been thoroughly treated by TURP and obtained satisfactory results. TURP surgery can be said to be one of the earliest minimally invasive surgeries in urology to benefit the majority of patients. With the advancement of technology, lumpectomy technology has been rapidly applied in various fields of urology, such as laparoscopy, retroperitoneoscopy, percutaneous nephroscopy, ureteroscopy, fiber cystoscopy, fiber ureteroscopy, laser lithotripsy, pneumatic ballistic lithotripsy and a series of minimally invasive surgeries have gradually replaced the traditional open surgery, and in 2014, our department In 2014, more than 80% of surgeries were performed through minimally invasive methods, including laparoscopic or extraperitoneal laparoscopic radical nephrectomy, renal unit preservation surgery, pyeloplasty, radical prostatectomy, radical cystectomy, pelvic lymph node dissection, inguinal lymph node dissection and other difficult surgeries; various minimally invasive stone removal procedures, such as extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy for stone extraction, ureteral The Department of Surgery has a wide range of minimally invasive stone removal procedures, such as extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy, ureteral lithotripsy, fiberoptic ureteroscopy, etc.
