Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones.The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract.
These include partial or total duplication of the ureter (a duplex ureter), or the formation of a second irregularly placed ureter; [13] or where the junction with the bladder is malformed or a ureterocoele develops (usually in that location). [14] If the ureters have been resited as a result of surgery, for example, due to a kidney transplant ...
Ureterovesicular junction obstruction (UVJ obstruction) is an obstruction at the level of the ureter and bladder. It accounts for 20% of cases of hydronephrosis detected in utero. It is also most commonly seen in males and involved both sides of the urinary tract in approximately 25% of cases. [1]

[5] [4] [6] [7] CVA tenderness may be present in patients who have a kidney stone, [8] [7] a stone in the ureter, [8] a ureteropelvic junction obstruction, [8] a kidney abscess, [8] a urinary tract infection, [9] and vesicoureteral reflux. [10] CVA tenderness is also present in patients who have retrocecal appendicitis and retroperitoneal ...
Bladder location and associated structures in the male. In males, the prostate gland lies outside the opening for the urethra. The middle lobe of the prostate causes an elevation in the mucous membrane behind the internal urethral orifice called the uvula of urinary bladder. The uvula can enlarge when the prostate becomes enlarged.
The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary bladder , the rest of the large intestine (the lower portion), and the internal reproductive organs .
Common causes of upper tract obstruction include obstructing stones and ureteropelvic junction (UPJ) obstruction caused by intrinsic narrowing of the ureters or an overlying vessel. Obstruction occurring in the lower urinary tract can also cause this increased pressure through the reflux of urine into the kidney.
