Abstract

The invention discloses a stent tube for ureter end-to-side anastomosis. The stent tube comprises a single J tube, wherein a transition joint is arranged at one end of the single J tube; an inlet is formed in the upper end of the transition joint; two symmetrically-arranged outward-protruding outlets communicated with the inlet are formed in the lower end of the transition joint; the lower end of the transition joint is positioned between the two outlets, and a mounting groove is formed between the two outlets; an elastic sheet is embedded in the mounting groove; the upper end of the elastic sheet is matched with the mounting groove; two independent positioning elastic sheets extend into the lower end of the elastic sheet; two hoses are respectively connected to the two outlets; inserted grooves are formed in the opposite sides of the two hoses; and the two positioning elastic sheets are respectively matched with the corresponding inserted grooves. When the two positioning elastic sheets are both positioned at a first station, the two positioning elastic sheets are parallel to each other, and when the two positioning elastic sheets are positioned at a second station, the two positioning elastic sheets are respectively bent outwards.

Description

technical field [0001] The invention relates to a stent tube, in particular to a stent tube used in end-to-side ureteral anastomosis. Background technique [0002] Duplicate kidney is a common congenital malformation of the urinary system in children. Its incidence is reported in the literature to be about 0.8%. Duplicate kidney deformity has various forms and renal function changes greatly. Therefore, children with duplicate kidney should formulate individualized treatment plans. He is also a pediatric urologist. Faced with one of the more difficult congenital deformities. Renal duplication is varying degrees of renal dysplasia and dilatation of the ureter of the pelvis, most commonly occurring in the upper half of the kidney. In the past, doctors used to resect the upper half of the kidney and its collecting system for such children. Recently, there have been reports of end-to-side ureteral anastomosis in the treatment of upper hydronephrosis with ureteral dilatation and...
