Abstract：It has been three decades since the application of ureteral stent in urological clinics. Due to the
non-degradability and biocompatibility of the making materials, there exist some defects and problems
in its clinical application, which also drives people to devote more efforts in exploring biodegradable
ureteral stent. Currently, there are some insecurity factors in the application of biodegradable stents,
such as randomness of degradation, long degrading time and too big degrading productions, etc. This
article mainly focused on the research progress of biodegradable stent from the aspects of degradable
biomaterials and making processes.
