There was no tumor recurrence and metastasis during the follow up with 4 to 10 months. ICG marking and near-infrared fluorescence imaging technology has now emerged as a safe, feasible and useful tool that may facilitate laparoscopic partial nephrectomy. ICG marking and near-infrared fluorescence imaging technology has now emerged as a safe, feasible and useful tool that may facilitate laparoscopic partial nephrectomy. To evaluate the clinical application of indocyanine green (ICG) visualization by near infrared fluorescence laparoscopy (NIFL) in complex upper urinary tract reconstructions surgery. 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 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. 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 ma
