ABSTRACT
OBJECTIVE@#To evaluate the clinical application of indocyanine green (ICG) visualization by near infrared fluorescence laparoscopy (NIFL) in complex upper urinary tract reconstructions surgery.@*METHODS@#This was a retrospective study of 7 patients who underwent complex surgeries of ureteral reconstruction between May 2019 and October 2019. There were 6 males and 1 female with the age ranging from 24 to 57 years (median age was 47 years). There were 5 cases of right ureteral strictures, of which 3 were proximal ureteral strictures and 2 were multiple and long ureteral strictures caused by radiotherapy. There were 2 cases of left ureteral strictures, of which 1 was ureteropelvic junction stricture and 1 was proximal ureteral stricture. There were 4 cases of secondary repair operations and 3 cases of primary operations. All the patients underwent laparoscopic surgery via the abdominal approach. ICG was injected into the ureter via nephrostomy tube during the operations, and the diseased ureter was identified by NIFL. Among the patients, 2 cases underwent IUPU (Institute of Urology, Peking University) modified ileal ureter replacement, 2 cases underwent ureteroureterostomy, 2 cases underwent appendiceal onlay flap ureteroplasty, and 1 case underwent lingual mucosa onlay flap ureteroplasty.@*RESULTS@#All the operations were successfully completed without open conversion. The localization and separation of ureteral lesions were completed under NIFL. The mean operative time was 187 (135-300) min. The duration of ureteral separation was 15-27 min, and the mean time was 18 min. The estimated blood loss was 15-200 mL, the mean estimated blood loss was 50 mL. There was one patient with ileal ureter replacement who had fever after surgery and responded well to antibiotics. The mean (range) length of postoperative hospital stay was 7 (6-10) days and no postoperative complications of a high grade (Clavien-Dindo Ⅲ and Ⅳ) occurred. Up to now, the mean follow-up duration was 9 (6-11) months, and no indocyanine green toxicity occurred. All D-J stents and nephrostomy were removed successfully 2 months after the operation. Ultrasound showed no obvious hydronephrosis, and CTU (computed tomography urography) showed that the urinary tract was unobstructed and the kidney function was normal.@*CONCLUSION@#The application of ICG in the complex upper urinary tract reconstructive surgery is a safe and easy method to help surgeon to identify the ureter which may reduce the risk of iatrogenic damage and protect the ureteral blood supply.
