We report a successful surgical intervention to repair bilateral ureteral strictures in a child with juvenile dermatomyositis (JDM) and ureteral calcinosis. This is the fourth reported case in medical literature. A 9-year-old-girl with severe JDM, a rare connective tissue disease characterized by skin and muscles vasculitis, was under immunosuppressive therapy. In the course of the disease, she...

Ureteral activity during the intravesical infusion was examined by urometry and electro-ureterograpby in 12 normal persons and a patient with vesico-ureteral reflux. The urometrograms and eloctro-uroterograms in normal persons indicated that when the bladder was distended with physiologic saline solution,the ureteral peristalsis responded so as to overcome the increased intravosical pressure. I...

Ureteral jets are the result of a forceful ejection of urine from the vesicoureteral junction into the urinary bladder. By using color Doppler ultrasonography (US), we aimed to identify distinct ureteral jets in dogs, provide insight into ureteral obstruction, and facilitate study of urodynamics and vesicoureteric sphincter function via pulsed Doppler US. Color Doppler US was applied to detect ...

The relationship between renal arterial pressure and renin release was examined in anesthetized dogs during complete or partial ureteral constriction. During complete ureteral occlusion ureteral pressure rose to 95+/-4 mm Hg and renin release increased from 1.7+/-0.7 to 22.3+/-3.1 mug/min; renal blood flow (RBF) was not significantly changed. Renin release was not further increased during subse...

A 23-year-old female had bilateral ureteral stents placed due to bilateral renal stones and hydronephrosis. The bilateral ureteral stents were changed every 3 months. A kidney ureter bladder (KUB) film showed left encrustation along the ureteral stent thus necessitating removal; however, the ureteral stent could not be removed cystoscopically. The ureteral stent was, therefore, extracted using ...

background the most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. hence, routine use of ureteral stents to prevent such complications seems logical; however, the optimal time to remove the ureteral stent is still controversial. objectives the purpose of this study was to compare the benefits and complications ...

BACKGROUND Ureteral herniations are a rare occurrence, generally found incidentally on cross sectional imaging or during surgical intervention for unrelated processes. Several locations of ureteral herniations can occur including the inguinal, femoral, sciatic, obturator, and thoracic regions. While few reports of ureteral hernias are reported in the literature overall, the vast majority of tho...

ureteral obstruction is relatively common after renal transplantation. a rare cause is the inguinal herniation of the transplant ureter. we report a case of late allograft renal transplant failure due to ureteral herniation as well as ureterovesical junction stenosis.

BACKGROUND Circumcaval ureters (CU) are a rare embryological malformation resulting in ventral displacement of the caudal vena cava, which crosses the ureter, potentially causing a ureteral stricture. OBJECTIVES To evaluate cats with obstructed CU(s) and report the presenting signs, diagnostics, treatment(s), and outcomes. Cats with obstructed CU(s) were compared to ureterally obstructed cats...

OBJECTIVES Ureteral stenosis is a common complication after a kidney transplant. Treatment for ureteral stenosis ranges from interventional procedures to open surgery. The aim of this study is to present classification for ureteral stenosis and recommend the targeted strategy for effective treatment. MATERIALS AND METHODS Twelve cases of ureteral stenosis were diagnosed among 193 kidney trans...
