Lumenscope technology Mirrors, whether in daily life or in all walks of life, people have seen, used and heard of countless, and in the medical field is also inseparable from the diagnosis and treatment tools, microscopes bring the human perspective to different levels of the microscopic world, allowing cellular, subcellular and molecular structures to be presented in front of the eyes. Endoscopes are made for different purposes by using optical principles and combining them with the natural cavities of the human body – called lumpectopes. The process of treating a disease on a color screen using a lumpectomy, with the help of special instruments, and through video technology is called lumpectomy. The hallmark of modern urology is a lumpectomy rate of more than 70%. According to the age of application of different lumpectomies, the following is a brief introduction from far to near for the benefit of readers: Cystoscopy: is the origin of medical endoscopy, cystoscopy technique is the basic skill of urologists, but also the basis of urological lumpectomy. Directly peer into the bladder cavity, with the help of accessories for surgical operations, foreign body removal, lithotripsy and lithotripsy, lesion biopsy and upper urinary tract examination, urethral dissection meeting. Prostate electrosurgery: This technology has been introduced in China since the late 70s and is another technique that reflects the basic skills of the urologist after cystoscopy. In conjunction with cutting tools, transurethral electrodesiccation of the prostate is performed. There is no question that this technique is the gold standard for the treatment of prostatic hyperplasia, especially in high-risk, elderly patients who are more minimally invasive, safe and efficient. The skillful techniques such as transurethral bladder tumor resection and urethral stricture dissection done with the use of electrosurgery have been mastered by most urologists. Laparoscopy: It was introduced to China in the 1990s to treat the adrenal gland, kidney, ureter, bladder, prostate, cryptorchid, varicocele and retroperitoneal lymph nodes with the help of operating parts through the abdominal cavity, retroperitoneal space or through the extraperitoneal retropubic route – called urological laparoscopy technique. The abdominal cavity and retroperitoneal space are different from the general cavity organs, which are not connected to the outside world, so it is necessary to create a channel for the lumpectomy and operation instruments to pass through during surgery. Ureteroscopy: The ureteroscope is implanted into the ureter via the urethra and bladder to treat upper urinary tract lesions under direct vision with accessories – called ureteroscopic techniques; including characterization of abnormal images that are not clear on urography, examination of naked eye hematuria, intracavitary treatment of upper urinary tract strictures and tumors, foreign body removal, ureteral intubation, etc., and cooperation with holmium laser to complete ureteral stone Lithotripsy and stone extraction. Percutaneous nephrolithoscopy: Under ultrasound guidance, the nephrolithoscope is inserted into the renal pelvis and calyces after skin puncture through the lumbar back, and its accessories are used to treat intrarenal lesions under direct vision – called percutaneous nephrolithoscopy technology. It is mainly used to treat upper urinary tract stones and also to deal with abnormalities of renal structures: diverticula of the calyces, funicular stenosis, congenital and postoperative stenosis or atresia of the ureteral junction, hydronephrosis, drainage of pus accumulation, removal of pelvic tumors, repair of postoperative leakage in the upper urinary tract, etc. Currently, cystoscopic techniques, although traditional and ancient, still have a great deal to work with. Electrocystoscopic techniques have been affirmed by a large body of evidence-based medicine and are no longer a hot topic for me in urological academic societies. Laparoscopy as a minimally invasive surgical technique and direction of development is emerging, with various subspecialties competing to carry out, and Chinese urology is unique in pioneering retroperitoneoscopic techniques, with prostate cancer and bladder cancer radical treatment being the top laparoscopic techniques yet to be popularized. Ureteroscopy and percutaneous nephrolithoscopy are mainly used for the treatment of upper urinary tract stones, and together with extracorporeal shock wave lithotripsy, they have become a modern treatment for stones, revolutionizing the treatment of traditional open surgery. Especially for complex kidney and upper ureteral stones, surgical residual stones and deerstalker stones, percutaneous nephrolithoscopy is the cutting-edge technology representing the standard of urological expertise at present, and it is also the key discussion content of large and small academic meetings. Robotic surgery has just started, and only 2~3 hospitals in China have introduced it.
