Polyurethanes (PUs) are expanding to newer horizons in the field of biomedical sciences, particularly due to their exceptional set of properties that deem fit for applications in the said field. On the other hand, carbohydrates find increasing attention as components of biomedical devices due to their easy availability from renewable resources. The manipulation of PUs by carbohydrate has solved the major concern of biodegradability, biocompatibility and economy. This review summarizes the recent trends in PUs embedded with carbohydrates ranging from monosaccharide to polysaccharides, including supramolecular host such as cyclodextrin etc. Diverse approaches for embedding them in PUs in various forms have been listed. In recent decade, significant research has been carried out to employ such polymers in biomedical applications such as drug delivery devices, implants, scaffolds for tissue engineering etc. This knowledge could facilitate the selection of more efficient approach for synthesis of polymeric systems based on the biological macromolecules.

聚氨酯（PU）不断扩展到生物医学领域，特别是由于它们的特殊性能使其适合于该领域的应用。另一方面，由于碳水化合物易于从可再生资源中获得，因此碳水化合物作为生物医学设备的组成越来越受到关注。碳水化合物对PU的控制解决了生物降解性，生物相容性和经济性的主要问题。这篇综述总结了从单糖到多糖（包括超分子宿主，如环糊精等）内嵌有碳水化合物的PU的最新趋势。已经列出了将它们以各种形式嵌入PU的多种方法。近十年来
