RATIONALE In patients with bilateral ureteral obstruction, the serum creatinine levels are often elevated, sometimes causing postrenal acute kidney injury (AKI). In contrast, those with unilateral ureteral obstruction present normal serum creatinine levels, as long as their contralateral kidneys are preserved intact. However, the unilateral obstruction of the ureter could affect the renal funct...
The objective of the present study was to evaluate the effects of a selective beta(3)-adrenoceptor agonist, (R, R)-5-[2-[[2-(3-chlorophenyl)-2-hydroxyethyl]-amino]propyl]-1, 3-benzodioxole-2,2-dicarboxylate (CL 316243), on the acutely obstructed ureter in anesthetized dogs. After a complete ureteral obstruction produced by the inflation of a balloon catheter placed within the left lower ureter,...
This case report describes a distal ureteral atresia along with ureteropelvic junction obstruction which occurred in a 19-month-old female child. It is easily to be misdiagnosed as mere ureteropelvic junction obstruction and omitted the combined diagnosis of distal ureteral atresia. Dismembered pyeloplasty was done in local hospital after admission, however with the result of recurrent fever wh...
Ureteral stent placement is usual after renal transplantation to avoid ureteral obstruction and facilitate reconstruction. However, stent is prone to infection, encrustation, migration, fragmentation, obstruction, and even obstructive nephropathy with a long-indwelling time. Forgotten ureteric stent in renal transplant recipients is scarcely reported. Here, we present a case of long-forgotten i...
Surgical treatment of primary obstructive megaureter is generally recommended when ureteral dilatation is likely to contribute to symptoms such as pyelonephritis or calculi. The authors' objective for this study was to present the surgical results performing ureteral reimplantation, combined with modified Lich-Gregoir antireflux procedure (using anchoring stitch) over a 10 year period. The aver...
A patient with acute ureteral obstruction caused by buckshot is reported. Its occurrence is rare, and its management is similar to that of ureteral calculus.
BACKGROUND/AIM Renal oxidative stress occurs in ureteral obstructions. The purpose of this study was to investigate the effect of the antioxidant and antiischemic agent trimetazidine (TMZ) on oxidative stress following ureteral obstruction. MATERIALS AND METHODS Ten groups were established. Sham groups were checked as controls after 1 and 3 weeks. The other 8 groups had partial or complete ur...
A case is reported of ureteral obstruction due to retained corpus luteum. The patient had previously undergone a hysterectomy and salpingo-ovariectomy with incomplete removal of ovarian tissue on both sides. The ureteral obstruction was treated by the excision of the mass and the reimplantation of the obstructed ureter into the bladder hitched to psoas muscle.
PURPOSE We review our experience using a new and easily removable ureteral catheter in patients who underwent complicated ureteral reimplantation. Our goal was to shorten hospital stay and lower anxiety during catheter removal without fear of postoperative ureteral obstruction. MATERIALS AND METHODS Between April 2009 and September 2010, nine patients who underwent our new method of catheter ...
The goal of the present study was to evaluate the role of endoglin, a transforming growth factor-beta1 (TGF-beta1) accessory receptor, in the pathogenesis of renal fibrosis. This was achieved by testing a model of tubulo-interstitial fibrosis induced by unilateral ureteral obstruction in endoglin heterozygous (Eng(+/-)) mice. Northern and Western blot analysis revealed that endoglin expression ...
