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.
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, 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 ...
Chronic upper urinary tract obstruction is treated by the insertion of a ureteric stent or a pyeloplasty. [13] Lower urinary tract obstruction (such as that caused by bladder outflow obstruction secondary to benign prostatic hyperplasia) is usually treated by insertion of a urinary catheter or a suprapubic catheter. Surgery is not required in ...
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. and. Brickers bladder (also called Ileal conduit) problems.
In addition to his work on urinary catheters, Foley also described a novel technique for treating strictures of the pelvi-ureteric junction which is known as the Foley Operation or the Foley Y-plasty pyeloplasty. [5] He also invented a hydraulic operating table [6] and a rotatable resectoscope, [7] and described the first artificial urethral ...
It is commonly used to diagnose upper tract obstruction, hydronephrosis, and ureteropelvic junction obstruction. In this, radiocontrast dye is injected into the renal pelvis and X-rays are taken. It provides detailed anatomy of the upper collecting system.
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 ]
