Ureteropelvic junction obstruction (UPJ obstruction) is an obstruction at the level of the ureter and renal pelvis. It is the most common cause of hydronephrosis detected in utero and is the most common anomaly detected on prenatal ultrasounds.
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]
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]
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 ]
Several conditions can result in urinary obstruction. In both adults and children, masses, such as abscesses and tumors, can compress the ureter. In children, hydronephrosis can be caused by ureteropelvic junction obstruction, ectopic inserted ureter, primary megaureter and posterior urethral valve (Figure 13).
In adults and children age 2 and older, use it only on the neck and chest to ease coughing during a cold, per the Mayo Clinic. Vicks VapoRub is made of ingredients such as camphor, eucalyptus oil ...
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.
