After 2\u2009months, dysuria occurred, and ultrasonography revealed a needle\u2010shaped high\u2010intensity protruding from the prostate into the bladder. Cystoscopy examination found a seed link connector. With the possibility of natural dissolution of the seed link, careful observation was chosen. However, 16\u2009months later, hematuria occurred, and an X\u2010ray revealed a bladder stone encompassing the seed. Compared with the X\u2010ray right after seeding, the seed located near the right bladder neck had fallen. The seed was removed by transurethral bladder lithotripsy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Seeds should be carefully located within the prostate, otherwise a
