Membranous glomerulonephritis, the most common cause for nephrotic syndrome in adults, peaks in people ages 40–60 years old and it is twice as likely to occur in men than in women. Since nephrotic syndrome is the most common cause of RVT, people over 40 years old and men are most at risk to develop a renal vein thrombosis. [3]
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.
Atherosclerosis: Overview. This article was reviewed by Craig Primack, MD, FACP, FAAP, FOMA. Atherosclerosis happens when a fatty substance called plaque builds up inside your arteries.
An unusual manifestation of NCS includes varicocele formation and varicose veins in the lower limbs. [9] Another clinical study has shown that nutcracker syndrome is a frequent finding in varicocele-affected patients and possibly, nutcracker syndrome should be routinely excluded as a possible cause of varicocele and pelvic congestion.

Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
In terms of cause, almost any condition that involves ischemia can lead to renal papillary necrosis. A mnemonic for the causes of renal papillary necrosis is POSTCARDS: pyelonephritis, obstruction of the urogenital tract, sickle cell disease, tuberculosis, cirrhosis of the liver, analgesia/alcohol use disorder, renal vein thrombosis, diabetes mellitus, and systemic vasculitis.

Therefore, weight-loss success is defined as someone losing at least half that weight and keeping it off for at least 5 years. “The long-term success with diet and exercise alone is about 2–5% ...
Sources of obstruction that can arise from other various causes include kidney stones, blood clots or retroperitoneal fibrosis. [5] A 2019 review found three cases of hydronephrosis with renal colic were caused by malpositioned menstrual cups pressing on a ureter. When the cups were removed, the symptoms disappeared. [6]
