What is the rate of reproductive tract anomalies in patients with unilateral renal agenesis?
20% of males (ipsilateral absence of seminal vesicle, epididymis or vas deferences). 70% of females (uterine or vaginal atresia; unicornuate uterus being most common).
What other anomalies are associated with renal agenesis?
Congenital heart disease (30%) and MSK anomalies (15%). Renal agenesis is present in 30% of VATER syndrome cases.
What are some long-term complications of renal agenesis?
Patients are at increased risk of renal dysfunction (normally mild), proteinuria (~10%) and hypertension (~30%).
Solitary enlarged left kidney. There is a focal wedge-shaped area of cortical hypoattenuation in the left interpolar region. Surrounding fat stranding and enlarged left para-aortic lymph nodes. There is a tiny right renal bud seen but a right ureter is present. Hepatic flexure fills the renal bed. No other genitourinary tract anomaly identified.
