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 of the obstruction at the level of the ureter: Open surgery. Less invasive treatment: laparoscopic correction. Minimal invasive treatment: Overtoom procedure: [4] dilatation with cutting balloon catheter followed by introduction of the pyeloplasty balloon catheter. [5]
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.
Kidney obstruction – commonly causes ureteropelvic junction obstruction (UPJ) [1] which is a blockage at the area where the ureter connects to the renal pelvis. This can lead to urinary stasis which can promote infection and stone formation. [4]
Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention . Complete obstruction of the urinary tract requires prompt treatment for renal preservation. [ 1 ]
Since lupus can impact different parts of the body, symptoms may vary. The disease is most common in women aged 15 to 44, Stockdale noted. Americans were curious about how much water they should ...
The ureteric balloon catheter is intended to cure two major types of diseases: Ureteropelvic junction obstruction (also called UPJ obstruction or Pelvic-ureteric junction obstruction PUJO) [1] caused by intrinsic wall factors as fibrosis and / or hypertrophic wall problems.
These animals possess an adult kidney derived from the metanephros. [24] The duct that connects the kidney to excrete urine in these animals is the ureter. [24] In placental mammals, it connects to the urinary bladder, whence urine leaves via the urethra. [25] In monotremes, urine flows from the ureters into the cloaca. [26]
