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.
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.
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.
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.
The urostomy is fashioned as previously described and connected by ureteroenteric anastomosis to the transplant ureter. Urinary tract infections are unfortunately very common because stomas are natural colonisers of bacteria; in transplant patients, antibiotic treatment, often over a long term and more frequent appliance changes are effective ...
Transurethral surgery has been the cornerstone of endourology. Most of the urinary tract can be reached via the urethra, enabling prostate surgery, surgery of tumors of the urothelium, stone surgery, and simple urethral and ureteral procedures. Recently, the addition of laparoscopy and robotics has further subdivided this branch of urology.
Obstruction of the ureter most commonly occurs at the site where the ureters are reconnected to the urinary diversion created. A small, hollow, flexible tube called a stent may be placed inside the ureter at the time of surgery to possibly help the reconnection site to heal. This reconnection site is also at risk for leaking urine within the ...
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 ...
