Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (renal calculus) develops in the urinary tract. [2] Renal calculi typically form in the kidney and leave the body in the urine stream. [2] A small calculus may pass without causing symptoms. [2]
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.

Blood in urine usually clears up after 48 to 72 hours. Bleeding longer than this period may signifies more serious bleeding complication. About 2–4% of percutaneous nephrostomy cases require blood transfusion. [9] Arteriovenous fistula is a rare complication.

[3] [4] [1] He used a small hook to keep the stone in one position, and then a blunt instrument to ...
[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. Normally, the anteroposterior diameter of the renal pelvis is less than 4 mm in fetuses up to 32 weeks of gestational age and 7 mm afterwards. [2]
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.
