In recent years, with the rapid development of minimally invasive urological surgery, the indications for endoluminal urological surgery have been broadened, and the degree of endoluminal urological surgery has become a measure of the level of urological surgery. Endoluminal urological surgery is an important part of minimally invasive surgery because of its low blow to patients, few complications, fast postoperative recovery and short patient hospitalization time. The Department of Urology of Run Run Shaw Hospital has been striving to develop minimally invasive surgical techniques and broaden the indications for endoluminal urological surgery. Extracorporeal shock wave lithotripsy for pelvic and calyx stones with poor results and calyx diverticulum stones with calyx neck stenosis have long been a very difficult situation for urologists to deal with. In the past, stones could only be removed by percutaneous nephrolithotomy or open surgery, or the stones could be left untreated and the patient could be followed up. Although percutaneous nephrolithotomy is a minimally invasive procedure, the surgery requires access through the kidney parenchyma to establish a channel, which is still more invasive and risky. The soft ureteroscope can be actively bent to be able to observe the upper urinary tract areas that cannot be reached by rigid ureteroscopes such as the pelvis and calyces, which is a milestone in the history of the development of endoluminal urology and is currently the ideal means to deal with the above-mentioned types of refractory kidney stones. Ureteroscopic surgery is performed through the natural lumen (urinary tract) under direct vision, which is less painful and quicker to recover, and leaves no scars on the body surface. The Department of Urology of the First Affiliated Hospital of Zhengzhou University actively explores and carries out the clinical application of ureteroscopic technology, especially for the treatment of intra-pelvic and intra-diverticular stones, which are difficult to treat, and has achieved very good results. After ultrasound examination, he was diagnosed with left lower ureteral calculus and left kidney stone. The doctor suggested him to undergo left ureteral rigidoscopy to deal with the left ureteral stone and release the urinary tract obstruction, because the co-existing kidney stone was in a high position and the ureteral rigidoscope could not reach that position and the kidney stone could not be dealt with at one time. He did not agree because although the renal colic could get better after the surgery, he was worried thinking that the kidney stone could fall down at any time and cause renal colic again. The residual kidney stone was like a time bomb weighing on his mind. He wanted to be able to take out both ureteral and kidney stones at one time. The First Affiliated Hospital of Zhengzhou University is famous for its minimally invasive urological procedures, so he came here on his behalf. After a detailed evaluation of his condition, the urology treatment team performed a soft ureteroscopic surgery to remove both the left ureteral stone and the left kidney stone at one time.
