ICD-9-CM Volume 3 is a system of procedural codes used by health insurers to classify medical procedures for billing purposes. It is a subset of the International Statistical Classification of Diseases and Related Health Problems (ICD) 9-CM.
Metanephric adenoma (MA) is a rare, benign tumour of the kidney, that can have a microscopic appearance similar to a nephroblastoma (Wilms tumours), [1] or a papillary renal cell carcinoma. It should not be confused with the pathologically unrelated, yet similar sounding, mesonephric adenoma .
The system of tissue induction between the ureteric bud and the metanephric blastema is a reciprocal control system. GDNF, glial cell-derived neurotrophic factor , is produced by the metanephric blastema and is essential in binding to the RET receptor on the ureteric bud, [ 1 ] which bifurcates and coalesces as a result to form the renal pelvis ...
Metanephric dysplastic hematoma of the sacral region (MDHSR) has been described by Cozzutto and Lazzaroni-Fossati in 1980, [1] by Posalaki et al. in 1981 [2] and by Cozzutto et al. in 1982. [3] Three additional cases were seen by Finegold.
The mesonephric duct, also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct, is a paired organ that develops in the early stages of embryonic development in humans and other mammals. It is an important structure that plays a critical role in the formation of male reproductive organs.
[17] [6] [18] Differences in kidney structure are the result of adaptations during evolution to variations in body mass and habitats (in particular, aridity) between species. [ 19 ] [ 20 ] [ 12 ] The cortex and medulla of the kidney contain nephrons , [ 21 ] each of which consists of a glomerulus and a complex tubular system. [ 22 ]
The ureteric bud, also known as the metanephric diverticulum, [1]: 50 is a protrusion from the mesonephric duct during the development of the urinary and reproductive organs. [ 2 ] [ 3 ] It later develops into a conduit for urine drainage from the kidneys, which, in contrast, originate from the metanephric blastema .
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
