Pain not related.: Assuming that this condition was treated and you now have normal kidney function, it is very unlikely that the knee pain has any connection to this past condition.The differential diagnosis is quite large for bilateral knee pain and tenderness. If there is no history of injury, you most likely have some sort of arthritis. A consultation family physician or rheumatologist is definitely in order. ...Read more
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
PUV serious problem: Posterior urethral valves cause severe urinary tract obstruction. They are located at level of external urethral sphincter, distal to bladder neck & prevent urine from passing. Can cause severe kidney damage before birth, as evidence by kidney swelling (hydronephrosis). Bladder & bladder neck can be greatly thickened & first part of urethra, before valves is widely open. Treated by resection. ...Read more

Monitor/Do nothing: With any medical diagnosis, 'doing nothing' is aka monitoring for a defined time and recheck to see if progression occurred. The risk benefit analysis is in favor of monitoring until serious complication is emminent. With a leaking heart valve, dilated heart chamber, decreased exercise tolerance, are watched with echo. Each case is different, so stay in touch with your cardiac team. Be well. ...Read more

Heart valve problems: The heart also has four valves: the tricuspid, pulmonary, mitral, and aortic valves. These valves open and close, acting like doors in the heart, making sure that blood flows correctly from the atria into the ventricles, and then from the ventricles to the rest of the body. Valves can become too leaky, allowing blood to flow backwards, or too narrowed, preventing blood from leaving a chamber. ...Read more
Depends on problem: Sometimes a valve that doesn't open properly can be helped by opening with a balloon procedure. Sometimes a prosthesis can be passed into the heart via a catheter. Other problems can be fixed by surgically trimming or tightening the valve. In many cases, the best available treatment is to remove the valve and replace it with an artificial valve made from metal, plastic, fabric, or animal tissue. ...Read more
4: 4 cardiac valves. 2 atrioventricular and 2 ventriculoarterial. 2 on the right heart 2 on the left heart. Each ventricle has an atrioventricular and a ventriculoarterial valve.They are one way valves. Flow is venae cavae to right atrium, RA to right ventricle via right av valve or tricuspid, rv to pulmonaryartery via pulmonic valve-lungs-left atrium-mitral valve-left ventricle-aortic valve- aorta. ...Read more
The canal through which urine exits the bladder, discharging the urine externally. In men, it is about 20-cm long with a membranous, prostatic, bulbar, and pendulous segments ending at the glans penis; it gives passage to the spermatic fluid as well as urine.
