    "abstract": "We describe a new transurethral technique for distal ureter management and the improvement of intraoperative exposure during LESS-NU.\nA total of 20 transurethral assisted LESS-NU were performed between May 2018 and December 2020 in our institution. The access route for the operation was via a single-port, with four channels placed through a transumbilical incision. After the lower ureter was separated from the bladder wall, a 1470 laser working channel was placed through the urethra to precisely cut the ureteral orifice. Following this, a self-made urethra auxiliary port was inserted through the bladder cuff opening to facilitate a resection of the ureter and kidney. The peri-operative and postoperative data were then retrospectively collected and analysed.\nAll procedures were completed successfully and one patient needed an additional port. The mean operative time was 196.8\u00a0\u00b1\u00a045.8\u00a0min and the mean estimated blood loss was 58.9\u00a0\u00b1\u00a032.0\u00a0ml. The days required for the surgical drain removal and the hospital stay were 4.6\u00a0\u00b1\u00a04.6 and 11.1\u00a0\u00b1\u00a06.4 days, respectively. One patient developed a fever following surgery but there were no major complications. During the average follow-up period, which lasted 25.5 months, one patient developed spinal cord metastasis and died 8 months after surgery. No obvious abnormalities were found in any of the other patients.\nThe tansurethral approach of the distal ureter for LESS-NU is deemed safe and efficient. The technique used offers accurate control of the distal ureter and good exposure of LESS.",
