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]
Treatment, depending on cause, may require prompt drainage of the bladder via catheterization, medical instrumentation, surgery (e.g., endoscopy, lithotripsy), hormonal therapy, or a combination of these modalities.
Hydronephrosis due to a kidney stone at the ureteral vesicular junction seen on CT scan. Prenatal diagnosis is possible, [9] and in fact, most cases in pediatric patients are incidentally detected by routine screening ultrasounds obtained during pregnancy. [10]
That gap was largest in the U.S., as Americans live in poor health for an average of 12.4 years, compared to 10.9 years in 2000. ... "While medical advancements have extended life expectancy, ...
[1] [2] Urine normally travels in one direction (forward, or anterograde) from the kidneys to the bladder via the ureters, with a one-way valve at the vesicoureteral (ureteral-bladder) junction preventing backflow. The valve is formed by oblique tunneling of the distal ureter through the wall of the bladder, creating a short length of ureter (1 ...
Life expectancy may be plateauing. Don’t expect your grandkids to live to 200 years old. A study published on Monday suggests we may be reaching our limit in terms of life expectancy and that ...
Figure 18. Renal stone located at the pyeloureteric junction with accompanying hydronephrosis. [1] With US, larger stones (>5–7 mm) within the kidney, i.e., in the calyces, the pelvis and the pyeloureteric junction, can be differentiated, especially in the cases with accompanying hydronephrosis (Figure 18 and Figure 19).
