CAMARGO, Celeste R. de et al. Uremic neuropathy: an overview of the current literature. Rev. Assoc. Med. Bras. [online]. 2019, vol.65, n.2, pp.281-286. ISSN 0104-4230.


Peripheral neuropathy is a disorder that affects the cell body, axon or myelin of motor or peripheral sensory neurons and occurs in 60-100% of patients who are submitted to dialysis due to chronic kidney disease. Uremic neuropathy is attributed to the accumulation of organic waste, evident in patients with reduced glomerular filtration rate.


This review aims to make clinical characteristics of uremic neuropathy evident enabling early diagnosis and treatment.


This is a literature review of articles published on PubMed over the last 10 years using “Uremic Neuropathy” as “Title/Abstract”.


A total of nine articles that met the inclusion criteria were included. UN is a distal symmetric sensorimotor polyneuropathy that occurs due to the accumulation of uremic toxins associated with an oxidative stress-related free radical activity. Hyperkalemia is thought to play an important role in its pathophysiology. Diagnosis depends on nerve conduction studies, and treatment includes dialysis or renal transplant.


Clinical presentations of UN are broad and non-specific; nonetheless, it is important to detect early changes in order to avoid its progression. The earlier UN is diagnosed and treated, the more successful are the clinical outcomes.

Keywords : Neural conduction; Dialysis; Kidney Transplantation; Peripheral Nervous System Diseases; Uremia/complications.
