It is the most common cause of hydronephrosis detected in utero and is the most common anomaly detected on prenatal ultrasounds. [1] [2] It occurs in approximately 1 in every 1500 live births, is most commonly seen in males, involves the left ureter twice as often as the right ureter. [1] [2] UPJ obstruction is transient in most cases. [2]
Treatment, depending on cause, may require prompt drainage of the bladder via catheterization, medical instrumentation, surgery (e.g., endoscopy, lithotripsy), hormonal therapy, or a combination of these modalities. [citation needed] Treatment of the obstruction at the level of the ureter: Open surgery. Less invasive treatment: laparoscopic ...
Common causes of upper tract obstruction include obstructing stones and ureteropelvic junction (UPJ) obstruction caused by intrinsic narrowing of the ureters or an overlying vessel. Obstruction occurring in the lower urinary tract can also cause this increased pressure through the reflux of urine into the kidney.
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.
Pyeloplasty is a type of surgical procedure performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate. [1]This revision of the renal pelvis treats the obstruction by excising the stenotic area of the renal pelvis or uretero-pelvic junction and creating a more capacious conduit using the tissue of the remaining ureter and renal pelvis.
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 ]
One study in The Journal of Urology found that PDE5 inhibitors reduced emergency room visits per month by 4.4-fold in patients with recurrent priapism. Of 24 patients, 22 reported improvement in ...
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]
