A case of transvaginal lithotripsy for a giant vaginal calculus

INTRODUCTION: Primary vaginal calculi are relatively rare, compared with secondary calculi. Primary calculi are often a result of urogenital sinus abnormalities, neurogenic bladder, or chronic incontinence. CASE PRESENTATION: Forty‐seven years old female with cerebral palsy since infancy had longstanding urinary incontinence. She visited her doctor for a fever and was referred to us with a urinary tract infection. Imaging revealed a large vaginal calculus. It was not possible to remove the calculus vaginally without crushing it, so we performed rigid cystoscopy with lithotripsy, using a pneumatic lithotripsy device. The calculus was completely removed without complications. CONCLUSION: We were able to remove a large primary vaginal calculus using ultrasonic and pneumatic lithotripsy through a rigid cystoscope. Minimally invasive surgery is a good option for patients with large vaginal calculi.
