“…Although conventional ureteral catheters have been used to locate the ureter, their effectiveness is limited. This is because conventional catheters may be difficult to visualize in cases with surrounding tissue adhesion, and the ureter cannot be recognized without touching the catheter‐inserted ureter 5 . Recently, a near‐infrared ray catheter (NIRC™) fluorescent ureteral catheter (NIRFUC; Nippon Covidien, Ltd, Tokyo, Japan) has been developed, enabling visualization of the ureter under near‐infrared irradiation 5,6 .…”

IntroductionThere have been reports of surgery for residual ureteral tumors, most of them involved open surgeries. Herein, we report a case of retroperitoneal scopic left ureteral resection and partial cystectomy, performed by placing a fluorescent ureteral catheter in the residual ureter.Case presentationA 79‐year‐old man was admitted to our hospital with a chief complaint of gross hematuria. He had undergone transperitoneal left radical nephrectomy due to angiomyolipoma 20 years ago. Computed tomography and Magnetic resonance imaging revealed a solid tumor in the left residual ureter. Retroperitoneal scopic residual ureterectomy has been performed. During the operation, a fluorescent ureteral catheter proved to be very helpful in detecting the ureter.ConclusionA fluorescent ureteral catheter is considered to be a useful tool in laparoscopic surgery, especially in cases where identification of the ureter is expected to be difficult, such as the residual ureter in this case.

Laparoscopic extended colectomy is a standard procedure for hepatic flexure tumours. Complete mesocolic excision improves specimen quality and lymph node yield [1-3]. In the case of cT4b colon cancer, the laparoscopic procedure may be challenging due to the involvement of other visceral organs and also cost consuming due to the use of multiple endo-staplers.Video S1 demonstrates a step by step approach to laparoscopic extended colectomy with complete mesocolic excision for a hepatic flexure tumour involving the jejunum with emphasis on radicality of the surgery and cost reduction.
