Pyelonephritis affects about 1 to 2 per 1,000 women each year and just under 0.5 per 1,000 males. [ 5 ] [ 7 ] Young adult females are most often affected, followed by the very young and old. [ 2 ] With treatment, outcomes are generally good in young adults.
Among children, urinary tract infections are most common in uncircumcised males less than three months of age, followed by females less than one year. [28] Estimates of frequency among children, however, vary widely. In a group of children with a fever, ranging in age between birth and two years, 2–20% were diagnosed with a UTI. [28]
It is sometimes used as a test for the diagnosis of acute pyelonephritis. [4] However, the sensitivity of DMSA scan for acute pyelonephritis may be as low as 46%. [5] Procedure: Patient is injected with 2-5 mCi of Technetium-99m DMSA intravenously and static imaging is done using Gamma camera after 2-3 hours.
All males with recurrent UTIs (urinary tract infections) or abnormality on ultrasound if first UTI. Females < 3 years of age with their first UTI. Females < 5 years of age with febrile UTIs; Older females with pyelonephritis or recurrent UTIs; Suspected obstruction (e.g. bilateral hydronephrosis) Suspected bladder trauma or rupture
This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia). [8] [10] Signs and symptoms that are consistent with nephritic syndrome include: Hematuria (red blood cells in the urine) [11]
Nephrotic syndrome can affect any age, although it is mainly found in adults with a ratio of adults to children of 26 to 1. [ 62 ] The syndrome presents in different ways in the two groups: the most frequent glomerulopathy in children is minimal change disease (66% of cases), followed by focal segmental glomerulosclerosis (8%) and ...
[2] [3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (4 + 1 ⁄ 2 inches) in length. [4] [5] They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.
Adults generally have a specific gravity in the range of 1.010 to 1.030. Increases in specific gravity (hypersthenuria, i.e. increased concentration of solutes in the urine) may be associated with dehydration, diarrhea, emesis, excessive sweating, urinary tract/bladder infection, glucosuria, renal artery stenosis, hepatorenal syndrome, decreased blood flow to the kidney (especially as a result ...
