How many types of pyeloplasty are there?
There are different types of pyeloplasty depending on the surgical technique and patterns of incision used. These include the Y-V, Inverted ‘U,’ and Dismembered types of pyeloplasty. The dismembered type of pyeloplasty (called as Anderson-Hynes pyeloplasty) is the most common type of pyeloplasty.
What is Anderson-Hynes pyeloplasty?
Background: The Anderson-Hynes pyeloplasty (AHP) is a surgical technique used in the management of pelvi-ureteric junction obstruction. This operation has been performed for over six decades and has etched its name in the annals of urology.
How is a stent removed after pyeloplasty?
The stent is removed in the operating room a few weeks after surgery. This is a same day surgery procedure. Another tube, called a drain, may be inserted in the area around the kidney and ureter to drain extra fluid that can collect during and after surgery. Once the drainage stops the drain is removed at the bedside.
What is the ureteropelvic junction?
Ureteropelvic junction (UPJ) obstruction is a blockage in the area that connects the renal pelvis (part of the kidney) to one of the tubes (ureters) that move urine to the bladder. It generally occurs when a baby is still growing in the womb.
What is hydronephrosis with ureteropelvic junction obstruction?
In UPJ obstruction, the kidney makes urine faster than it can be drained through the renal pelvis into the ureter. This causes urine to pool in the kidney, which leads to kidney swelling (hydronephrosis). Often, only 1 kidney is affected. The enlarged kidney is easily seen on ultrasound.
Does stent removal require anesthesia?
Since no intravenous line is inserted and there is no anesthesia, you do not have to be accompanied by anyone else and you can eat normally before and after the procedure. For those patients who prefer having the stent removed under IV sedation, arrangements must be made for post-operative patient transportation.
