What causes Calyceal diverticulum?
Potentially acquired causes of calyceal diverticula can be broadly classified as obstructive, neuromuscular, traumatic, or fibrotic. Obstruction has been proposed as a factor secondary to stone formation28 or infection either within the calyx or from a localized cortical abscess draining into a calyx.
Is Calyceal diverticulum painful?
Calyceal diverticula are usually asymptomatic; however, they can become problematic at times. These diverticula are known to be associated with flank pain, hematuria, recurrent urinary tract infections (UTIs), and calculus formation.
What is Calyceal stone?
Calyceal calculi. The renal calyces are the most common location for asymptomatic urinary calculi, which are often incidentally discovered on an imaging study performed for another indication. Calyceal stones may also be diagnosed during evaluation of flank pain, microscopic hematuria, and urinary tract infection.
What do the calyces do?
The large end of the pelvis has roughly cuplike extensions, called calyces, within the kidney—these are cavities in which urine collects before it flows on into the urinary bladder.
How is Calyceal diverticulum treated?
Caliceal diverticula represent a therapeutic challenge for the endourologist. Treatment options for symptomatic, stone-bearing, caliceal diverticula include shockwave lithotripsy (SWL), ureteroscopy, percutaneous nephrostolithotomy/ablation, and laparoscopic unroofing.

[1] The typical appearance includes uniform wall thickening, thickened and irregular calcifications, and thickened and irregular or multiple septa (>1 mm) without an intracystic nodular lesion.
Do Calyceal stones cause pain?
These observations suggest that small caliceal stones can cause pain. The results of treatment are such that it is justifiable to treat a small caliceal stone in patient suffering from flank pain of no other known cause.
How is Calyceal stone treated?
The upper calyceal stone represents about 15% of calyceal stones [2], shock wave lithotripsy (SWL) is considered the first line of treatment of such stones when their size is less than 2 cm, and percutaneous nephrolithotomy (PCNL) is indicated when their size is 2 cm or more or after failure of SWL [3].
What causes pelvocaliectasis of the kidney?
Common causes of pelvicaliectasis include an ileal loop diversion, prune belly syndrome, multicystic dysplastic kidney, and polycystic kidney disease.

What is calyceal Diverticulectomy?
Calyceal diverticulum. Dr Daniel J Bell ◉ and Dr Mohammed Al Khader.O.Thabet ◉ et al. Calyceal diverticula, also known as pyelocalyceal diverticula are congenital outpouchings from the renal calyx or pelvis into the renal cortex. These diverticula are lined with transitional cell epithelium.
What are the renal calyces?
Renal calyces are parts of the kidney that collect urine before it passes further into the urinary tract. The calyces are part of the renal pelvis, a convex system of sinuses that connect the innermost part of the kidney to the ureters and, from there, to the bladder. There are two types of renal calyx: the minor calyx and the major calyx.
