Abstract:
Objective To review the method of proximal ureteral external pruning in laparoscopic dissociated ureteral stricture in our hospital and to analyze the feasibility and safety of this method. Methods A total of 10 patients underwent transabdominal laparoscopic ureteral stricture surgery in our hospital from March 2012 to October 2018, all of whom were treated by external pruning after proximal ureter was pulled out along the puncture device. Results Under this method, 30 cases were successfully completed surgery, successfully intercepted lesions. Their ureters were keep in good condition, with no open surgery.The average operation time was (107.9 ± 13.5) min, the average blood loss was (48.7 ± 3.8) mL and the average length of hospital stay was (7.8 ± 1.3) d, with no anastomotic fistula and no anastomotic stricturet for about 0.5 to 3 years of followup.Referring kidney seeper, moderate water was in 2 cases, mild water in 6 cases and 2 cases disappeared.7 cases of renal scintigraphy were improved, 7 cases of ureteral contrast were enhanced and 3 cases were improved. Conclusion In operations of different patients with ureteral stricture or pyeloplasty, the proximal ureteral clip as in the laparoscopy is difficult to accurately determine the lesion location, length and etc. Therefore,they can be cut in vitro. After pruning satisfactory, they were continuously accepted operation, which can reduce the difficulty of cavity operation and accurately detect the pathological changes. It could provide a safe and
