A traditional open renal ureter resection and bladder cuff-like resection mostly involve upper and lower incisions, which require changing positions and disinfecting the surgical towels twice. The operation time is long, and the amount of trauma is large. Laparoscopic renal ureter and bladder sleeve resection have been gradually adopted by urologists since minimally invasive surgery techniques have been widely used in urology8. The methods for laparoscopic nephroureterectomy and radical resection ...

Radical nephroureterectomy is a standard procedure for treating upper tract urothelial carcinoma (UTUC)1. Traditional open surgery requires two large incisions in the lower abdomen, which is associated with a large amount of trauma and many complications2. With the rapid development of minimally invasive techniques in urology, laparoscopic surgery has been gradually applied in many research studies. Laparoscopic surgery is identical to open surgery in treating the tumors, so the traditional surgical methods have gradually been replaced by laparoscopic surgery3.
In laparoscopic surgery, treatment of the terminal ureter has been an area of focus and a known difficulty of the surgery. At present, different choices exist for treating the ureteral end in laparoscopic nephroureterectomy. However, reductions in the difficulty of the surgery and the amount of trauma has not been possible4,5.
After years of exploration, our center has improved and adopted a new method for the treatment of the terminal ureter: precutting the medial umbilical fold not only increases the operating space but also reduces the difficulty of the surgery and minimizes extra trauma to the patient.

technical modification of the terminal ureter during total transperitoneal laparoscopic nephroureterectomy for upper urinary tract urothelial carcinoma

Upper tract urothelial carcinoma (UTUC) accounts for 5%&ndash;10% of all urothelial tumors. Radical nephroureterectomy is the standard treatment procedure. At present, different choices still exist for treating the ureteral end during laparoscopic ureteral bladder sleeve resection. Our center has adopted a new method for treating the ureteral end. This new method can increase the operating space and reduce the difficulty of the surgery compared with current methods.

In total, 87 patients underwent surgery without difficulties, and there were no open surgeries. The average age of the patients was 67.25 &#177; 9.90 years. Within this group, there were 47 cases of renal pelvic cancer, 10 cases of pelvic cancer with ureteral cancer, and 30 cases of ureteral cancer (10 cases of upper ureteral cancer, 9 cases of middle ureteral cancer, and 11 cases of lower ureteral cancer). In total, 49 cancers were on the left side and 38 cancers were on the right side. The average tumor diameter was 3....
