Bilateral very large calcium oxalate stones in the seminal vesicles: case report and literature review

A 29-year-old man with hypospadias and bilateral undescended testicles presented with recurrent attacks of lower urinary tract infections and painful ejaculation. He was diagnosed to have very large bilateral seminal vesicle stones. The pelvis X-ray showed two radio-densities located in the pelvis with symmetrical appearance while Ultrasound showed them as echogenic structures with posterior acoustic shadowing. In magnetic resonance imaging (MRI) of the pelvis they appeared hypointense in both T1-weighted and T2-weighted images while pelvic computed tomography scan (CT scan) showed bilateral huge stones in the seminal vesicles. The stones were extracted by open surgery through the bladder after transurethral excision of the ejaculatory ducts. Here, we report the first case of bilateral, large, heart-shaped, calcium oxalate monohydrate of seminal vesicle caliculi with brief literature review.
