Taking the STING Out of Ureteral Obstruction
نویسندگان
چکیده
Vesicoureteral reflux (VUR) is diagnosed in ∼1% of children. The main goal of treatment is preservation of renal function by preventing recurrent urinary tract infection (UTI) refractory to antibiotic therapy. Surgical treatment options include endoscopic injection or ureteral reimplantation. Subureteral Teflon (polytetrafluoroethylene) injection (STING) is an endoscopic treatment option no longer in common practice. Use of Teflon is no longer advised because of a number of documented complications secondary to local and distant migration of injected material. We present a case of delayed ureteral obstruction secondary to the STING procedure occurring 21 years after initial surgery and managed using a novel endoscopic method.

Modification of the sting procedure for vesicoureteral reflux: ureteral repositioning and injection.
OBJECTIVE Over the past 20 years endoscopic treatment (ET) of vesicoureteral reflux (VUR) has changed the algorithm of reflux management. We describe a modification of the standard subureteral injection (STING) that has contributed to the increased success rate of this procedure. METHODS Between January 2006 and December 2006 192 children, 5 months to 10 years old (mean age 2.8 years) underwe...
متن کاملRenin-angiotensin system and unilateral ureteral obstruction
Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...

Submucosal injection of Teflon for treatment of vesicoureteral reflux (the sting of O'Donnell) was used in 43 patients (66 ureters-21 bilateral cases). 14 patients were on dialysis and reflux was diagnosed at medical evaluation during pretransplantation work-up; correction of reflux was indicated as a preparation for renal transplantation. In another group of 24 patients with normal renal funct...
متن کاملCombination Therapy with Losartan and α-Tocopherol in Acute Ureteral Obstruction-Induced Renal Excretory Dysfunction and Acidification Defect
Background: Previous study by the authors showed that a-tocopherol prevents oxidative stress but would not improve depressed excretory variables in post-obstructed kidney (POK) after release of 24-h unilateral ureteral obstruction (UUO). This study is a supplementary investigation on the effects of a-tocopherol combined with an antagonist of angiotensin-II type-1 (AT1) receptor on renal dysfunc...

flow. Losartan is angiotensin II receptor I (AT1) antagonist and is used for treatment of congestive heart failure and hypertension. It is widely recognized that Losartan has organ protective nature and most effective for organ damage progressing. The aim of this study was to evaluate the effect of Losartan on apoptosis in renal tissue after unilateral ureteral obstruction in rat. Materials and...
