Renal agenesis epidemiology and demographics

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Shakiba Hassanzadeh, MD [2]

Overview

The general incidence of unilateral renal agenesis (URA) has been reported to be approximately 1 in 2031 individuals. Males are more commonly affected by unilateral renal agenesis (URA) than females. The incidence of bilateral renal agenesis (BRA) is approximately 1 in every 3000 pregnancies. The mortality rate of bilateral renal agenesis (BRA) without prenatal therapy is 100 %.

Epidemiology and Demographics

Incidence

The general incidence of unilateral renal agenesis (URA) has been reported to be approximately 1 in 2031 individuals, however, the incidence of URA based on prenatal studies alone has been reported to be 1 in 8091.^[1]
The incidence of bilateral renal agenesis (BRA) is approximately 1 in every 3000 pregnancies.^[2]^[3]

Prevalence

A report showed that the overall prevalence of unilateral renal agenesis (URA) was 4 per 10,000 in all births which included terminations of pregnancy (TOP) and intrauterine deaths (IUD).^[4]

Mortality rate

The mortality rate of bilateral renal agenesis (BRA) without prenatal therapy is 100%.^[5]

Gender

Males are more commonly affected by unilateral renal agenesis (URA) than females. It has been reported that 63% of the patients with URA are male.^[1]
