Ureterovesicular junction obstruction (UVJ obstruction) is an obstruction at the level of the ureter and bladder. It accounts for 20% of cases of hydronephrosis detected in utero. It is also most commonly seen in males and involved both sides of the urinary tract in approximately 25% of cases. [1]
Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones.The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract.
Hydronephrosis describes hydrostatic dilation of the renal pelvis and calyces as a result of obstruction to urine flow downstream. Alternatively, hydroureter describes the dilation of the ureter, and hydronephroureter describes the dilation of the entire upper urinary tract (both the renal pelvicalyceal system and the ureter).
Treatment of the obstruction at the level of the ureter: Open surgery. Less invasive treatment: laparoscopic correction. Minimal invasive treatment: Overtoom procedure: [4] dilatation with cutting balloon catheter followed by introduction of the pyeloplasty balloon catheter. [5]
Kidney stones are becoming more common with time, and their incidence is believed to increase recently due to unhealthy diet habits. The passage of kidney stones into ureters might lead to their impaction and the development of local inflammatory process around the stone in addition to the obstruction of the ipsilateral kidney and build up of pressure manifested as hydronephrosis.
Preureteric vena cava or retrocaval ureter is an uncommon congenital anomaly where the right ureter runs behind and medial to the inferior vena cava (IVC) due to dysgenesis of the IVC. This abnormality has been diagnosed using computed tomography urography (CTU), nuclear scintigraphy , ultrasound , intravenous urography , and magnetic resonance ...
