PURPOSE: We describe a new transurethral technique for distal ureter management and the improvement of intraoperative exposure during LESS-NU.
METHODS: A 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.
RESULTS: All procedures were completed successfully and one patient needed an additional port. The mean operative time was 196.8 ± 45.8 min and the mean estimated blood loss was 58.9 ± 32.0 ml. The days required for the surgical drain removal and the hospital stay were 4.6 ± 4.6 and 11.1 ± 6.4 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.
CONCLUSION: The 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.
