2023年12月1日 · Syngeneic collagen tubes were used for the reconstruction of the rat ureter. The presence of urine flow may promote the regeneration of urothelium. Covering a cardiomyocyte sheets improved patency of Biotube. Novel strategy of ureteral reconstruction was presented.

In our in vivo rat model of ureteral obstruction, silodosin reduces ureteral pressure with less systemic side effects than tamsulosin and prazosin. Silodosin exhibits better inhibitory efficacy on EFS-induced contraction of human and rat isolated ureters than tamsulosin and prazosin.

A technical innovation of a novel ureter implantation technique on rat kidney allograft transplantation is described. The left kidney graft is transplanted heterotopically into the left infrarenal position, using vascular conduits from donor abdominal aorta and inferior vena cava in continuity to re …

2020年2月13日 · Sprague–Dawley rats were randomly divided into Group I: sham operation, Group II: autologous ureteral anastomosis, and Group III: isogenic kidney transplantation with ureteral anastomosis. For the anastomosis, a polyimide stent with a previously placed 11-0 silk was inserted into the ureter. The stent and ureter were fixed with 11-0 silk sutures.

20 小时之前 · The rat sub-total nephrectomy (SNx) is a functional model of general chronic kidney disease (CKD) where the main pathological driver is glomerular hypertension representative of several subtypes ...

In the first intervention group (fifty rats named K1), the proximal ureter, upper to the sacral brim, was ligated using the Monocryl suture 3−0 to produce a complete obstruction in the ureteral lumen. In group two (fifty rats named K2), the ureter was ligated in the middle part (at the level of the sacrum) in the same fashion.

2023年10月13日 · Introduction: Ureteral injuries require surgical intervention as they lead to loss of renal function. The current reconstructive techniques for long ureteral defects are problematic. Consequently, this study aimed to reconstruct the ureter in a rat model using subcutaneously prepared autologous collagen tubes (Biotubes).

2013年2月4日 · In our in vivo rat model of ureteral obstruction, silodosin reduces ureteral pressure with less systemic side effects than tamsulosin and prazosin. Silodosin exhibits better inhibitory efficacy on EFS-induced contraction of human and rat …

2014年1月21日 · Smooth muscle cell (SMC) orientation in intact rat ureter is predominantly longitudinal. Panel A shows the orientation distribution (3D plot) and the cell density (2D graph) as function of depth, averaged over 36 rat ureter segments. Normalized depth 0 corresponds to the adventitial side of the muscle layer and 1 to the proprial side.

2020年2月1日 · To investigate the utility of diffusion kurtosis imaging (DKI) MRI for evaluation of renal fibrosis in rats with unilateral ureteral obstruction (UUO). Twenty-five rats had UUO, and ten rats were subjected to sham operation as control. DKI was performed on a 3.0 T MRI scanner on days 1, 3, 5, and 7 after ligation.
