The study documented the successful use of a fluorescent ureteral catheter to improve visualization of the ureters during laparoscopic surgery, increasing surgical safety. Real-time confirmation of ureter positions was achieved, and no complications were found during the follow-up period.
Ureteral injury can occur during total laparoscopic hysterectomy. This report documents our experience in using the near infrared ray catheter (NIRC), a newly developed fluorescent ureteral catheter made of material that contains a fluorescent dye to improve visualization of the ureters. We have used the device in 3 patients between 40 and 50 years of age (mean, 46.3 +/- 4.5 years) undergoing total laparoscopic hysterectomy and bilateral salpingectomy for uterine myomas. The time of catheter insertion ranged from 4 minutes and 9 seconds to 10 minutes and 57 seconds. A number of intraoperative procedures were performed near the ureters, namely, identification and ligation of the uterine arteries, dissection of the cardinal ligament, incision of the vaginal canal, and suturing of the vaginal stump. The abovementioned fluorescent ureteral catheter appears green on a monitor when illuminated by near-infrared light, and this facilitated real-time confirmation of the ureter positions, increasing surgical safety. The patients were followed up for 6 months postoperatively, and no urinary tract infection or injury was found. Prophylactic use of the fluorescent ureteral catheter may improve visualization of the ureters in patients considered to be at high risk of ureteral injury, such as those expected to exhibit ureteral deviation due to severe adhesions or an enlarged uterus and when the surgeon has little experience in laparoscopic surgery.
