Ureteral strictures that are mainly occurring by reappearance of a primary malignancy or extrinsic compression by a tumor are a unique subgroup of strictures that will be done with endoscopic incision. Most urologists presently advocate an endoscopic incision as the primary management for most ureteral strictures. Endoureterotomy is the procedure of choice for the initial management of benign ureteral strictures. This technique has constantly been connected with higher success rates.
PROCEDURE:
Even though not as usually reported as the endoscopic treatment of ureteropelvic junction obstruction, endoureteromy for ureteral obstruction at other sites is nonetheless an successful minimally invasive method. Most ureteral strictures other than at the ureteropelvic junction are acquire, and are very frequently iatrogenic. Endoureterotomy for distal and upper ureteral strictures less than 2 cm and not related with radiation or other ischemic injury is extremely successful and results in minimal morbidity.
-
Endoureterotomy, whether performed in retrograde or antegrade fashion, is other minimum invasive procedure of choice for the management of ureteric strictures.
-
This method is done under with ureteroscopic control and regularly combines with balloon dilatation.
-
A cut was started from the ureteral lumen out to periureteral fat in a full-thickness method and should encompass 2–3 mm of normal ureteral tissue.
-
Stricture characteristics influence the achievement rates of endoureterotomy as much as any minimally invasive method.
-
Degree of ischaemia and length of stricture are the mainly important prognostic factors for success.
-
Radiation-induced and malignant strictures usually respond badly to endoureterotomy. This is mainly due to the ischaemic nature of the lesion, as well as the segmental distribution that is frequently encountered, particularly in advanced malignancy.
