The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral.Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic.
A number of important medical conditions are caused by stones: [citation needed] Nephrolithiasis (kidney stones) Can cause hydronephrosis (swollen kidneys) and kidney failure; Can predispose to pyelonephritis (kidney infections) Can progress to urolithiasis; Urolithiasis (urinary bladder stones) Can progress to bladder outlet obstruction
A kidney stone can move from the kidney and become lodged inside the ureter, which can block the flow of urine, as well as cause a sharp cramp in the back, side, or lower abdomen. [9] Pain often comes in waves lasting up to two hours, then subsides, called renal colic. [10] The affected kidney could then develop hydronephrosis, should a part of ...
Lithiasis (stone formation) in the kidneys is called nephrolithiasis (/ ˌ n ɛ f r oʊ l ɪ ˈ θ aɪ ə s ɪ s /), from nephro-, meaning kidney, + -lith, meaning stone, and -iasis, meaning disorder. A distinction between nephrolithiasis and urolithiasis can be made because not all urinary stones (uroliths) form in the kidney; they can also ...
The renal pelvis is the location of several kinds of kidney cancer and is affected by infection in pyelonephritis. [citation needed] A large "staghorn" kidney stone may block all or part of the renal pelvis. The size of the renal pelvis plays a major role in the grading of hydronephrosis.
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 .
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
Kidney stones are becoming more common with time, and their incidence is believed to increase recently due to unhealthy diet habits. The passage of kidney stones into ureters might lead to their impaction and the development of local inflammatory process around the stone in addition to the obstruction of the ipsilateral kidney and build up of pressure manifested as hydronephrosis.
