Unilateral Renal Agenesis Coexisting with Bilateral Cryptorchidism in an Adult Nigerian: Case Report

A case of unilateral renal agenesis discovered incidentally during an abdominal ultrasound scan to locate undescended testes in a 38 year old man is presented. There are very few reports about cryptorchidism in unilateral renal agenesis. In the general population cryptorchidism is seen in 4% of boys at birth decreasing to 1.8% at 1month of age and 0.8% at 9 months of age. This case is reported to highlight the association of thetwo conditions and to emphasize the importance of early diagnosis in order to institute treatment early to salvage the testis and preserve the solitary kidney from damage.Niger Med J.
