CFTR Variants and Renal Abnormalities in Males With Congenital Unilateral Absence of the Vas Deferens (CUAVD): A Systematic Review and Meta-analysis of Observational Studies

Abstract

(Abstracted from Genet Med 2019;21(4):826–836.) Congenital absence of the vas deferens (CAVD) is a urological disease classified into 3 subtypes: congenital bilateral absence of the vas deferens (CBAVD), congenital unilateral absence of the vas deferens (CUAVD), and congenital bilateral partial aplasia of the vas deferens. The most common subtype is CBAVD (prevalence of 1%–2%), but CUAVD (prevalence of 0.5%–1.0%) also may be discovered during evaluations for infertility or surgical procedures involving male genitalia.
