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.
An intravenous pyelogram is used to look for problems relating to the urinary tract. [5] These may include blockages or narrowing, such as due to kidney stones, cancer (such as renal cell carcinoma or transitional cell carcinoma), enlarged prostate glands, and anatomical variations, [5] such as a medullary sponge kidney. [6]
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.
This is due to the transfer of referred pain signals from the lower thoracic splanchnic nerves to the lumbar splanchnic nerves as the stone passes down from the kidney or proximal ureter to the distal ureter. This pain, known as renal colic, is often described as one of the strongest pain sensations known. [15]
CVA tenderness often indicates kidney pathology, but it may result from other medical problems. [4] CVA tenderness is often present in acute pyelonephritis . [ 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 ...
The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
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.
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
