Ureterovesical junction (UVJ) obstruction, causing Hydronephrosis and Hydroureter.

This video shows Ureterovesical junction (UVJ) obstruction, causing Hydronephrosis and Hydroureter. A ureteral stricture is a narrowing of the ureter that causes an obstruction in the flow of urine. This narrowing causes an obstruction in the flow of urine. It can also be caused by kidney stones, upper urinary tract inflammation, or a tumor. Ureterovesical junction (UVJ) obstruction refers to a blockage to this area. The obstruction impedes the flow of urine down to the bladder, causing the urine to back up into and dilate the ureters and kidney (megaureter and hydronephrosis). Ureterovesical junction (UVJ) obstruction refers to a blockage to this area. The obstruction impedes the flow of urine down to the bladder, causing the urine to back up into and dilate the ureters and kidney (megaureter and hydronephrosis). Because BPH is so common in older men, obstruction is more common among men. Other common causes of obstruction include strictures (narrowing caused by scar tissue) of the ureter or urethra that develop after radiation therapy, surgery, or procedures done on the urinary tract. A ureterovesical junction (UVJ) obstruction is a blockage to the area where the ureter meets the bladder. Ureterovesical junction obstruction (UVJO) is the result of an anatomic or functional abnormality in the distal segment of the ureter. What is the ureterovesical junction (UVJ) obstruction? The ureterovesical junction is located where the ureter (the tube that drains urine from the kidney) meets the bladder. Ureterovesical junction (UVJ) obstruction refers to a blockage to this area. Stones that block the ureter or any of the kidney's drainage tubes may cause symptoms that include: Severe, intermittent (comes and goes) pain in the upper flank (in the back, under the lower ribs) that can radiate (spread) to the lower abdomen, and; Nausea and vomiting. Treatment for urethral stricture may include surgical implantation of a stent to open the narrowed section of the ureter or minimally invasive robotic surgery to reconstruct the urinary tract. The goal is to fix the stricture permanently and avoid the long-term use of stents, whenever possible. 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, sepsis, and death. Ureteral obstruction is fairly common. Because it's treatable, severe complications are rare. Ureteral obstruction might have no signs or symptoms. Signs and symptoms depend on the site of obstruction, whether it's partial or complete, how quickly it develops, and whether it is unilateral or bilateral. Signs and symptoms might include:- Pain Changes in the amount of urine produced Difficulty in urinating Blood in the urine Repeated urinary tract infections High blood pressure (hypertension) Causes Duplication of the ureter. An abnormality where the ureter connects to the bladder or the kidney. Ureterocele. Retroperitoneal fibrosis. Other possible causes Ureteral stones Severe constipation, which is mostly seen in children but also occurs in adults Cancerous and noncancerous tumors Internal tissue growth, such as endometriosis in females Long-standing swelling of the ureter wall, usually due to diseases such as tuberculosis or a parasite infection called schistosomiasis.
