The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
Intravenous pyelogram (IVP): A special diagnostic test that follows the time course of excretion of a contrast dye through the kidneys, ureters, and bladder after it is injected into a vein. Retrograde pyelogram (RPG): X-ray study of the kidney, focusing on the urine-collecting region of the kidney and ureters. Antegrade nephrostogram.
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.
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [1]
Ureteroureterostomies are often performed because of injured or scarred ureters, especially when the ureter in question is damaged in its upper third section. [2] Generally if the patient has distal uretral strictures (narrowing of the ureter), [3] a ureteroureterostomy is not recommended and a ureter reimplantation would be favorable.
Another consequence of this procedure is an increased risk of kidney infections due to bacteria from faeces travelling back up the ureters (reflux). Patients are commonly put on oral prophylactic antibiotics to combat infections in the ureteral tract and kidneys, but this can lead to tolerance of the antibiotic.
Urostomy is most commonly performed after cystectomy, such as may be necessary in, for example, bladder cancer.Other indications include severe kidney disease, accidental damage or injury to the urinary tract, surgical complications because of non-related pelvic or abdominal surgery, congenital defects that cause urine to back up into the kidneys, or urinary incontinence.
A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
