Abstract

We present a case of spontaneous retrograde migration of ureterovesical junction stone to the kidney. A 26-year-old Bahraini male, diagnosed with left lower ureteric stone 7 months before this presentation. On his recent presentation, the stone has migrated down but not passed, confirmed on imaging. Operative removal was planned. X-ray kidney ureter bladder (KUB) in the morning of surgery did not reveal stone in the ureter, but the same shadow was seen in the kidney. An urgent computerized tomography-KUB was done, and this confirms the stone has migrated to the kidney. Surgery was canceled, and the stone was dealt with extracorporeal shockwave lithotripsy and was fragmented in the first session. This retrograde migration of lower ureteric stone to the kidney is not reported in the English literature in human before.
