Precision management of the ureteral tunnel via the Dual-Bridge technique during laparoscopic radical hysterectomy
This retrospective study demonstrates that the novel Dual-Bridge technique significantly improves surgical efficiency and reduces intraoperative blood loss during laparoscopic radical hysterectomy for cervical cancer by simplifying ureteral tunnel dissection, while maintaining safety comparable to conventional methods.

Imagine the human body as a bustling, high-tech city. In this city, the ureter is a vital, delicate water pipe that carries waste from the kidneys down to the bladder. Now, imagine a construction crew needs to demolish a specific building (the uterus) in the middle of this city. The problem? The water pipe runs right through a narrow, crowded alleyway next to the building, tangled up with a complex web of power lines (blood vessels) and thick, sticky tape (connective tissue). If the crew pulls the pipe too hard or cuts the wrong line, the whole city's plumbing could flood or burst. This is the daily challenge for surgeons performing a radical hysterectomy, a major surgery to remove the uterus to treat early-stage cervical cancer. For decades, surgeons have tried to navigate this "tunnel" carefully, but it's a tricky job that often leads to bleeding or accidental damage to the pipe. The big question in the medical world is: Can we find a smarter, safer way to clear this path without hurting the delicate structures around it?
This is exactly what a team of researchers from the Chongqing Health Center for Women and Children set out to solve. They tested a new, clever method they call the "Dual-Bridge" technique. Think of the old way of doing this surgery like trying to pull a tangled necklace out of a tight box by yanking on the clump of metal—it's messy, risky, and often breaks something. The new "Dual-Bridge" method is more like building two temporary, sturdy footbridges over the tricky parts of the alleyway. Instead of yanking the water pipe (the ureter) out of the way, the surgeons use two specific, natural gaps in the tissue to create a safe, clear path. The first bridge is built by finding a tiny, bloodless gap between the main artery and the pipe, allowing them to lift the artery safely. The second bridge connects to a space near the bladder, letting them cut the remaining tissue without ever having to stretch or pull the pipe.
In their study, the researchers looked back at the records of 197 women who had this surgery between May 2023 and May 2025. They split the group into two: 93 women who had the traditional "yank-and-cut" method, and 104 women who got the new "Dual-Bridge" approach. The results were quite promising. The surgeons using the Dual-Bridge technique finished the whole operation much faster, taking an average of 189.35 minutes compared to 221.22 minutes for the traditional group. They also spent less time specifically wrestling with the tricky artery and ligament area, cutting that part down to 41.73 minutes versus 50.90 minutes. Perhaps most importantly, the new method resulted in less blood loss, with the Dual-Bridge group losing an average of 107.12 mL compared to 129.35 mL in the conventional group.
Crucially, the paper suggests that this speed and efficiency didn't come at the cost of safety. The researchers found no significant difference in complications between the two groups; in fact, there were no ureteral injuries reported in the Dual-Bridge group, while there were two in the traditional group. The authors conclude that by using these natural "bridges" or gaps in the anatomy, surgeons can navigate the ureteral tunnel more precisely, minimizing blood loss and speeding up the surgery without increasing the risk of injury. While the study is a single-center look back at past cases and doesn't yet prove long-term survival rates, it strongly suggests that this ureter-centric approach is a safe and efficient upgrade for this delicate surgery.
