 NEPHROPTOSIS

Nephroptosis is a condition where the kidney drops more than 5cm towards the pelvis when moving from a lying down to upright position. Although the kidney moves into an abnormal position when the individual is upright, the kidney moves back to its original anatomical site when the individual lays flat. 

 

This condition mainly effects young slim women with the male to female ratio of 3:100. The right kidney is more commonly affected in 70% of individuals, with only 10% affecting the left kidney and 20% affecting both sides causing bilateral nephroptosis. The majority of cases are asymptomatic, however in a small percentage of individuals they can suffer from nephrotic symptoms which can be severe.

As symptomatic nephroptosis is an extremely rare condition, sufferers often struggle for several years to receive a diagnosis and have to visit a large number of specialists. Sufferers can also have difficulty finding a healthcare professional who knows about the condition and the surgical treatment of nephroptosis (nephropexy).

 

CAUSE OF NEPHROPTOSIS

The cause of nephroptosis is not fully understood, however with the majority of women being slim with a relatively low body mass index (BMI), theories of detachment relate to the lack of perirenal fat and fascia which usually keep the kidney positioned within the retroperitoneal space. A common factor which has been observed in patients with nephroptosis can be if the individual has experienced a sudden weight loss over a short period of time.
