Description
Yixuan Huang and colleagues present a graft source for rebuilding a narrowed ureter: the bladder's own lining. A 36-year-old woman arrived with a worsening blocked left kidney after endoscopic attempts failed, and imaging showed a stricture about five centimeters long in her mid-ureter. Because she was scheduled for dental implants, the cheek-mucosa graft was unattractive, so the team chose bladder mucosa, tissue at home in urine.
The robot-assisted operation ran in four steps: opening the strictured segment lengthwise, harvesting and thinning the graft, and sparing its inner layer. It ended with placing a stent with a ventral onlay join, and wrapping the repair in fat. Dye imaging confirmed the graft's blood supply. Surgery took 146 minutes with 10 milliliters of blood loss, and the hospital stay was five days. Six months on, the patient felt well, with stable kidney function and a draining kidney on scans.
