Beschreibung
Zusammenfassung:	A biodegradable double-J stent (1) and a method of manufacturing a biodegradable double-J stent (1) are provided. The stent (1) comprises a main tube (11), a first retaining tube (12), and a second retaining tube (13), each fabricated from a biodegradable material. The first and second retaining tubes (12,13) are curl-shaped and are connected to two ends of the main tube (11), respectively. The method of manufacturing a biodegradable double-J stent (1) comprises the steps of: (a) providing a tube made of a biodegradable material; and (b) bending two ends of the tube to render the two ends curl-shaped and keeping a middle segment between the two ends straight. The two curl-shaped ends define a first retaining tube (12) and a second retaining tube (13), respectively, and the middle segment defines a main tube (11). The biodegradable double-J stent (1) precludes a ureteral obstruction which might otherwise occur with conventional double-J stents not removed in a timely manner.
