What is boari flap?
Boari flap is the preferred method of repairing long- segment ureteral defects of 8–12 cm. The procedure has undergone change from classical open (transperitoneal and retroperitoneal) method to laparoscopic surgery and recently robotic surgery.
When do you use boari flap?
Boari flap is a useful option when the diseased segment of the ureter is too long, or ureteral mobility is too limited to perform a primary ureteroureterostomy. Boari flaps can be created to bridge a 10- to 15-cm ureteral defect.
What is psoas hitch?
A psoas hitch is a method of ureteric re-implantation following an injury to the ureter. The reconstruction is indicated when the distal ureter is injured or resected, and the remaining portion of ureter cannot reach the bladder for ureteral reimplantation.
What is Ureterocystostomy?
Ureteroneocystostomy (UNC) refers to reimplantation of the ureter into the bladder. In the adult population, ureteroneocystostomy is primarily used for disease or trauma involving the lower third portion of the ureter that results in obstruction or fistula.
How long does it take for ureter to heal?
Studies of ureteral healing have demonstrated that the mucosa has healed by 3 weeks and muscular continuity is established by 7 weeks. Thus, many recommend that a stent remain in place for 6-8 weeks after a repair. Stents come in various diameters (4-8F) and lengths.
What is bladder flap cesarean section?
Creation of the bladder flap is an integral step of the standard cesarean section. The bladder flap is made by superficially incising and dissecting the peritoneal lining to separate the urinary bladder from the lower uterine segment.
How is the ureter divided?
The ureter is arbitrarily divided into proximal (upper), middle (over the sacrum), and distal (lower) segments. However, according to international anatomic terminology the ureter consists of abdominal (from renal pelvis to iliac vessels), pelvic (from iliac vessels to the bladder), and intramural segments.
How do you reimplant a ureter?
Ureteral reimplantation surgery – children
- Detach the ureter from the bladder.
- Create a new tunnel between the bladder wall and muscle in a better position in the bladder.
- Place the ureter in the new tunnel.
- Stitch the ureter in place and close the bladder with stitches.
- If needed, this will be done to the other ureter.
What is Ureteropyelostomy?
[ yu-rē′tə-rō-pī′ə-lŏs′tə-mē ] n. Surgical formation of a junction of the ureter and the renal pelvis.
What is Ureteronephrectomy?

Can a stent damage your ureter?
[1] Ureteric stents are not complication free. Stent related complications are primarily mechanical; including stent migration, encrustation, stone formation and fragmentation. Stents act as foreign bodes and may cause urinary tract infection, pyonephrosis that may lead to nonfunctioning kidney.
Can ureter repair itself?
Occasionally, diversion of the urine stream with a nephrostomy or stent is the only intervention needed. Ureters without strictures heal in most patients. However, if a stricture does develop, it can be managed endoscopically with balloon dilation or endoureterotomy.
What does bladder flap mean?
Bladder flap is created through the cutting surface of the visceral peritoneum in order to isolate the bladder from the lower uterine segment. Basically, bladder flap is created for more access to the lower uterine segment in addition to reducing the risk of damage to the bladder during CS (1, 2).
What is a bladder flap hysterectomy?
The bladder flap is developed by lifting the anterior peritoneum and retracting the uterus cephalad to expose the bladder reflection and enter the vesicocervical space.(
How long does ureteral reimplantation last?
The surgery takes 2 to 3 hours. During surgery, the surgeon will: Detach the ureter from the bladder. Create a new tunnel between the bladder wall and muscle in a better position in the bladder.
What is the success rate of ureteral reimplantation surgery?
The success rate of laparoscopic or robotic ureteral reimplantation has been reported to range between 95% and 99% [15-17,40], which is comparable to that of open surgery; however, these values are based on a limited number of reports.
What is a Nephroureterectomy?
Nephroureterectomy, which is the removal of the kidney, entire ureter, and a small piece of bladder where the ureter and bladder connect, may be necessary when patients have been diagnosed with a mass or tumor within the lining of the kidney and/or ureter.
What is Nephrotomography?
Nephrotomography is a combination of rapid intravenous nephrography and body-section radiography. The procedure has been found to be of considerable value in the differentiation of renal cysts from neoplasms. The technic of the examination has been presented in a preliminary report (1).
What is Pyelolithotomy?
Pyelolithotomy is a surgical procedure used in cases involving a stone in the renal pelvis. Indications for pyelolithotomy include minimally branched staghorn stones in the renal pelvis of complex collecting systems and excessive morbid obesity.
How long can a stent stay in ureter?
Up to 3 months, and depending on if the growth will be removed, a stent can be left in place for years. However, stents must be changed on a regular basis of every 3-4 months.
How many times can a ureteral stent be replaced?
Your provider will replace the stent with a new one every three to six months. Replacing the stent reduces the likelihood of complications.
What can damage ureters?
Most injuries to the ureter occur during pelvic or abdominal operations, such as removal of the uterus (hysterectomy) or the colon (colectomy), cesarean delivery, or repair of an abdominal aortic aneurysm, or during ureteroscopy (an examination of the ureter with a rigid or flexible viewing tube).
How long does it take a ureter to heal?
What happens to your bladder in ac section?
Bladder cut during a C-section
If the obstetrician does not make their incision high enough, the cut will go through the bladder. If this mistake is not appreciated, the surgeon will proceed to cut into through the bladder and into the uterus. The baby will subsequently be delivered through the bladder.
What fills the space after a hysterectomy?
