OBJECTIVE To present our experience with the application of human amniotic membrane for the reconstruction of extensive ureteral wall defects. METHODS Between 2003 and 2006, 11 patients underwent reconstructive surgery of the ureter. A human amniotic membrane allograft was used to supplement ureteral wall defects. Indications for the procedure included ureteral strictures of a 5.5 cm average ...

OBJECTIVE Urinary tract obstruction is one of the most prevalent diseases in urology. The handling of it includes conservative (analgesia and fluid therapy) and invasive (urinary diversion) measures. Ureteral stent is the method currently employed for urinary tract diversion. Complications of urinary tract stents maintenance have already been studied and are well known. We report a case of ur...

Iliac vein-ureteral fistula is a rare cause of hematuria. The diagnosis of an iliac vein-ureteral fistula can be elusive even with the use of multiple methods. With regards to the treatment, there appears to be a shift in management from primarily open surgical to primarily angiographic management. We present a unique case of an external iliac vein - transplant ureteral fistula. A 48 year-old f...

MORITA, T., SuzuKI, T., KoNDO, S. and TSUCHIDA, S. Effects of Noradrena line and Acetylcholine on Ureteral Peristalsis. Tohoku J. exp. Med., 1983, 141 (4), 489-490 Experiments in vitro were performed to compare effects of noradrenaline and acetylcholine on the pyeloureter, both of which activate ureteral peristalsis. Noradrenaline elevated the baseline renal pressure to accelerate the ureteral ...

Renin secretion was studied in acute experiments in dogs during occlusion of the ureter alone (experiment 1), ureteral occlusion with a superimposed intrarenal infusion of papaverine (experiment 2), or ureteral occlusion with a superimposed intravenous ethacrynic acid injection (experiment 3) and following release of the ureteral occlusion (all three experiments). In all three experiments, uret...

Ureteral urothelial carcinoma (UC) is a rare malignant tumor. The most common clinical manifestations of ureteral UC are hematuria, increased urinary frequency, dysuria and pain. The diagnosis of ureteral UC is made via radiography, endoscopy and pathology. Although osteoblastic destruction is usually observed in metastasis of prostate cancer, UC can also be a reason for osteoblastic metastasis...

The surgical treatment of vesicoureteral relfux can range from injection therapy to open ureteral reimplantation. Minimally invasive applications for treatment of vesicoureteral relfux include laparoscopic extravesical and intravesical ureteral reimplantation. We present our extended experience of the technique for intravesical cross-trigonal ureteral reimplantation for vesicoureteral relux.

conclusions precise evaluation of patients with one renal abnormality could lead to detection of other associated anomalies. application of minimally invasive procedures such as ureteroscopic incision is highly recommended in ureterocele treatment. case presentation a middle-aged male was known to have horseshoe kidney, bilateral ureteroceles and a stone, 1 cm in diameter, in his right ureter. ...

The objective of the present study was to evaluate the effects of a selective b3-adrenoceptor agonist, (R,R)-5-[2-[[2-(3-chlorophenyl)-2-hydroxyethyl]-amino]propyl]-1,3-benzodioxole-2,2dicarboxylate (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, the int...
