Abstract:

OBJECTIVE: To investigate the clinical research and progress in experimental research of ureteral scaffold materials according to the summarization of related literatures in recent years.
METHODS: Taking “ureteral scaffold, curative effect, complication, biodegradation” in Chinese as search terms, Wanfang database (http://www.wanfangdata.com.cn) was retrieved by the first author. Totally 135 literatures about the clinical research and progress in experimental research of ureteral scaffold materials were selected. Published earlier, duplicate and similar researches were excluded, 20 documents were included.
RESULTS: In the practice of urology surgery, ureteral stent is commonly used equipment, which can be used to urinary calculus, reconstruction of urinary passage and urinary tract trauma. The main function of ureteral stent is to expand obstruction or narrow ureter, urine is drained into bladder. When kidney or ureter fistula was reduced, the healing of ureteral anastomotic was promoted. Ureteral scaffold material is non-biodegradation material; symptoms of bladder or shifting of stent, complications of vesicoureteral reflux, and stents surface calculi will be occurred in patients during the implantation of stent. The research about biodegradable nature of polymer biodegradability ureteral scaffold materials in vivo and in vitro is still at the stage of basic research.
CONCLUSION: Endoprosthesis of ureteral plays an important role in urinary surgery, but it is necessary to learn and pay attention to the prevention of complication of endoprosthesis, in order to obtain better curative effect. At present, scholars from various countries are trying to develop more appropriate ureteral scaffold materials.
