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.
Expected average success rate: The success rate for this procedure is between 70% and 85%, scrotal or penile island flap urethroplasty is considered the least attractive of repair options for urethral defects, it is, however, the standard procedure used in the repair of strictures greater than 4 cm in length. As with the buccal mucosal onlay ...
Risks during surgery include heart problems, pulmonary (lung) complications, development of blood clots , blocking of arteries , and injury to adjacent structures, such as bowel or vascular entities. Inadequate ureteral length may also be encountered, leading to ureteral kinking and subsequent obstruction.
Non-endoscopic open surgical procedures such as colon surgery where the operation field is very close to the adjacent retroperitoneal ureter is a well-known procedure where ureters can be injured, especially when surgical plans are distorted in conditions such as tethered colon cancer or advanced inflammatory bowel disease.
If the ureters have been resited as a result of surgery, for example due to a kidney transplant or due to past surgery for vesicoureteric reflux, that site may also become narrowed. [15] [1] A narrowed ureter may lead to ureteric enlargement and cause swelling of the kidneys (hydronephrosis). [13]
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.
Ureteral stent Ureteral stent (detail) 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 ...
A ureterovaginal fistula is a result of trauma, infection, pelvic surgery, radiation treatment and therapy, malignancy, or inflammatory bowel disease. Symptoms can be troubling for women especially since some clinicians delay treatment until inflammation is reduced and stronger tissue has formed. [2]
