A stone in each ureter.

This video shows a stone in each ureter. It is generally thought that only smaller stones can be impacted in the ureter but in this case, you can see a large stone of about 12.5 mm in Rt. ureter and a smaller stone of about 07.5 mm in Lt. Ureter, There is moderate to severe dilatation of the renal pelvicalyceal system on the Rt. side with moderate dilatation of the renal pelvicalyceal system on Lt. side. Once the stone gets caught in the ureter, it may partially or completely block the flow of urine. This blockage causes pain that is usually felt in the middle of the back or side and may radiate toward the groin. If a stone that is blocking urine flow is left untreated it can cause damage to the kidney or ureter. Left untreated, kidney stones can block the ureters or make them narrower. This increases the risk of infection, or urine may build up and put added strain on the kidneys. Approximately 60% of kidney stones that are 4–6 mm will pass on their own in about 45 days. Around 20% of kidney stones that are larger than 6 mm will pass on their own in about 12 months. However, when stones are this large, it is best to seek immediate surgical removal. Ureteral obstruction is a blockage in one or both of the tubes (ureters) that carry urine from your kidneys to your bladder. Ureteral obstruction can be curable. However, if it's not treated, symptoms can quickly move from mild — pain, fever, and infection — to severe — loss of kidney function, and sepsis. Relationship of Sexual Intercourse with ureteral stone in distal one-third of the ureter. Sexual Intercourse May Clear Distal Ureteral Stones. Having sex 3-4 times a week was associated with a significantly greater stone passage rate than tamsulosin or standard medical therapy. Sexual intercourse may be an effective way to clear distal ureteral stones, researchers have concluded. A ureteral obstruction that causes severe pain might require an immediate procedure to remove urine from your body and temporarily relieve the problems caused by a blockage. A ureteral stent, a hollow tube inserted inside the ureter to keep it open. Signs and symptoms of kidney and ureteral stones may include: Pain in the back and side, often just below the ribs. Pain that changes, from the kidney to the level of blockage into the ureter. Pain with urination. Nausea and/or vomiting. Frequency of micturition Urine that is cloudy or has a strong, foul smell. Blood in the urine. Most small stones in patients with relatively mild hydronephrosis can be treated with observation and acetaminophen. More serious cases with intractable pain may require drainage with a stent or percutaneous nephrostomy. Medium to large stones eventually begins to move from the kidney to the ureter, where they get stuck. The main symptom is severe pain on either side of the back. This pain results from the body's attempt to move the stone out of the ureter and into the bladder. Hydronephrosis is defined as distention of the renal calyces and pelvis with urine as a result of obstruction of the outflow of urine distal to the renal pelvis. Hydroureter is defined as a dilation of the ureter. If it's left untreated for too long, this pressure can cause your kidneys to lose function permanently. Mild symptoms of hydronephrosis include urinating more frequently and an increased urge to urinate. Other potentially severe symptoms you may experience are incomplete voiding or bladder emptying. Treatment for hydronephrosis depends on the underlying cause. Left untreated, severe hydronephrosis can lead to permanent kidney damage. Rarely, it can cause kidney failure. But hydronephrosis typically affects only one kidney and the other kidney can do the work for both. Hydronephrosis is a true emergency in patients with only one kidney and should the person believe that the lone kidney is at risk, urgent medical care should be accessed. Hydronephrosis caused by pregnancy usually goes away without treatment once the pregnancy comes to an end. If hydronephrosis is diagnosed before birth and is not severe, it usually gets better on its own without the need for treatment. About 4 out of every 5 cases will resolve on their own before or within a few months of birth and will cause no long-term problems for mother or baby. The remaining cases may require treatment with antibiotics to prevent kidney infections, and in some cases, surgery may be needed. The size of the stone is a major factor in whether it can pass naturally. Stones smaller than 4 millimeters (mm) pass on their own 80 percent of the time. They take an average of 31 days to pass. Stones that are 4–6 mm are more likely to require some sort of treatment, but around 60 percent pass naturally. Most small stones in patients with relatively mild hydronephrosis can be treated with observation and acetaminophen. More serious cases with intractable pain may require drainage with a stent or percutaneous nephrostomy.
