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.

CASE A female infant, born by cesarean delivery (dilation dystocia), was referred to our service at age of 24 hours with a history of “imperforate anus”. Physical examination revealed duplicity of the vulvar introit (urine output by the right orifice and feces by the left). She was submitted to the following imaging exams: (1) echodopplercardiogram – interatrial and interventricular communicati...

duplications of gastrointestinal tract are congenital anomalies found in about 0.2% of all children. these include the rare gastric duplication. we present such a cyst in a 14 years old girl with gastric outlet obstruction. she was found to have a noncommunicating antral duplication cyst .the cyst was managed by cystectomy and marsupialization. microscopically the duplication cyst contained a m...

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...
