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]
[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 ...
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral.Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic.
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).
The "healthspan-lifespan 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.
The Quality of Well-Being Scale (QWB) is a general health quality of life questionnaire which measures overall status and well-being over the previous three days in four areas: physical activities, social activities, mobility, and symptom/problem complexes. [1] It consists of 71 items and takes 20 minutes to complete. [2]
HuffPost published this information about hospice inspections as a resource for consumers making decisions about end-of-life care. The indicators do not necessarily reflect quality of care. The Washington Post in October published a database of other quality indicators. Both tools include information that in many states is difficult to access ...
Ultrasound imaging can give information on the shape of the bladder, post-void residual volume, and evidence of kidney damage such as kidney size, thickness or ureteral dilation. [9] Trabeculated bladder on ultrasound indicates high risk of developing urinary tract abnormalities such as hydronephrosis and stones. [10]
