- Ureteral avulsion is a rare but well known complication of ureteroscopy, almost always related to the use of an ureteroscope too large to be readily accommodated by the ureter or, in most cases, by an attempt to pull an inadequately fragmented or impacted stone down from the proximal or mid ureter.

- Although an infrequent event in the endoscopic management of ureteral calculi (0.2-1%) (7,8), with only few cases reported in the literature, ureteral avulsion is a potential serious complication that should always be taken into account when performing such procedures.

- Renal pelvis. The renal pelvis or pyelum is the funnel-like dilated proximal part of the ureter in the kidney. In humans, the renal pelvis is the point of convergence of two or three major calyces. Each renal papilla is surrounded by a branch of the renal pelvis called a calyx.

Background Vesicoureteral reflux (VUR) is characterized by the retrograde flow of urine from the bladder to the kidneys. VUR may be associated with urinary tract infection (UTI), hydronephrosis, and abnormal kidney development (renal dysplasia). The relation of these conditions to VUR is discussed in this article. Unrecognized VUR with concomitant UTI may lead to long-term effects on renal function and overall patient health.

- Overview. The ureters are paired muscular ducts with narrow lumina that carry urine from the kidneys to the bladder. An understanding of the anatomic relations of the ureters is critical to the practice of urology, as well as to the disciplines of gynecologic, vascular, and general surgery.he ureter then continues anteriorly on the psoas major muscle, crossing under the gonadal vein at the level of the inferior pole of the kidney. The ureters course medial to the sacroiliac joint and then curve laterally in the pelvis. The colon and its mesentery are associated anterior to the ureters.

- Ureters. The ureters are a pair of tubes that carry urine from the kidneys to the urinary bladder. The ureters are about 10 to 12 inches long and run on the left and right sides of the body parallel to the vertebral column.

Ureteropelvic Junction (UPJ) Obstruction What is Ureteropelvic Junction (UPJ) Obstruction? One of the main jobs of the kidney is to filter the blood, and deliver the waste products (urine) to the bladder. The urine leaves the kidney, enters the renal pelvis, and then passes into the ureter through a funnel called the ureteropelvic junction (UPJ). In some children there is a partial blockage at the UPJ. The blockage may be severe (high grade), minimal (low grade) or intermittent.

Ileal conduit surgery An ileal conduit is a small urine reservoir that is surgically created from a small segment of bowel. Both techniques are forms of reconstructive surgery to replace the bladder or bypass obstructions or disease in the bladder so that urine can pass out of the body.leal conduit surgery consists of open abdominal surgery that proceeds in the following three stages: 1  Isolating the ileum, which is the last section of small bowel. 2  The segment used is about 5.9–7.8 in (15–20 cm) in length. 3  The segment is then anastomosized, or grafted, to the ureters with absorbable sutures.

What is ectopic ureter? Ectopic Ureter. Ureters are the two funnel-shaped tubes that carry urine from the kidneys to the bladder. A ureter that does not connect properly to the bladder and drains somewhere outside of the bladder is called an ectopic ureter.

Ureter Ureter. The ureter is a tube that carries urine from the kidney to the urinary bladder. There are two ureters, one attached to each kidney. The upper half of the ureter is located in the abdomen and the lower half is located in the pelvic area.The ureter is about 10 to 12 inches long in the average adult.The tube has thick walls composed of a fibrous, a muscular, and a mucus coat, which are able to contract.

Crossed fused renal ectopia (CFRE) is a markedly rare congenital malformation of the urinary system where one of the kidneys crosses the midline to become located on the opposite side of its ureter entrance to the bladder and the parenchymas of the two kidneys fuse.ntroduction.

Ureter At the entrance to the bladder, the ureters are surrounded by valves known as ureterovesical valves, which prevent the backflow of urine. In females, the ureters pass through the mesometrium and under the uterine arteries on the way to the urinary bladder.

UreteroPelvic Junction (UPJ) Stenosis What is Ureteropelvic Junction Stenosis (UPJ Stenosis)? It is one of the most common benign diseases causing renal pelvis dilatation. It mosttly occurs in children and is mainly congenital (from birth). Ureteropelvic junction (UPJ) is the point where the ureter meets the renal pelvis. Renal pelvis is like a 'sink' collecting urine produced by the kidney, while UPJ is the 'sink-trap' (siphon) through which the urine has to pass so that it will end to the bladder through the ureter.

- The ureter can be injured during any anterior vaginal wall surgery that extends to the bladder neck (such as vaginal hysterectomy, bladder neck suspension surgery, anterior repair of the vaginal wall, repair of an enterocele [hernia] and neovagina construction).

- The diagnosis of obstructed megaureter is established radiographically based on definition of a dilated distal ureteral segment that inserts into a normal ureteral meatus. Findings on endoscopy reveal that these ureteral tunnels are not obstructed to retrograde passage of a ureteral catheter or probe.

- Renal hilus: The renal hilus is an indentation near to the centre of the concave area of the kidney. This is the area of the kidney through which the ureter leaves the kidney and the other structures including blood vessels (illustrated), lymphatic vessels, and nerves enter/leave the kidney.

Vesicoureteral Reflux Vesicoureteral reflux is the abnormal flow of urine from the bladder to the upper urinary tract. The urinary tract is the body’s drainage system for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra.

What are the Ureters? Ureters are tube-shaped organs that deliver urine from the kidneys to the bladder. Because the linings of the ureters and the bladder are continuous, it is possible for infection to start in the bladder and ascend into the tubes.Increasing one's intake of water may help promote the passing of kidney stones through the ureters. Kidney stones can block a ureter.hese 10 animal facts will amaze you. The ureters are tube shaped organs whose main function is to deliver urine from the kidneys downward to the urinary bladder. They have a funnel shaped area at the top where they connect to the kidneys called the renal pelvis. These tubes are approximately 9.8 inches (25 cm) long.

- The ureter is the tube that connects each kidney to the bladder. The kidneys clean the blood and filter waste from it. This process produces a liquid waste, urine.Urine flows … from the kidneys through the ureters to the bladder. The urine is stored in the bladder until a person urinates.During urination, the urine leaves the body by passing from the bladder through another tube, the urethra, which is open at one end. in humans, ureters are two pairs of long muscular tubes (about 25-30cm) that carry urine from kidneys to urinarry bladders.n example of this is a duplicate ureter, where there is an extra ureter running from a kidney to t … he bladder. Uterocele is a narrowing of the ureter which could cause urine to back up into the kidneys and damage the kidney. This is usually caused by a small tumor or hernia.

Ureteroceles A ureterocele is most commonly diagnosed by ultrasound. An ultrasound is very good at detecting dilation (hydronephrosis) of the kidney and ureter that can be seen with ureteroceles as well as detecting the ureterocele itself in the bladder. Other tests are often performed when a ureterocele is diagnosed.

- Ureters are the two funnel-shaped tubes that carry urine from the kidneys to the bladder. A ureter that does not connect properly to the bladder and drains somewhere outside of the bladder is called an ectopic ureter.In boys the ectopic ureter usually drains into the urethra closer to the prostate. Hydronephrosis: When the ectopic ureter connects outside the bladder, the insertion is usually narrow, creating a level of obstruction. 2  The urine that is draining from the kidneys backs up and causes the kidney and ureter to dilate (hydronephrosis).

Ureteral Injury During Gynecologic Surgery If the injury to the ureter is minor, easily reversible, and noticed immediately, the ureter may heal completely and without consequence. Inadvertent ligation of the ureter is an example of such an injury. If this injury is noticed in a timely fashion, the suture can be cut off the ureter without significant injury.
