Medical Must-See: Stone abruptly ruptures ureterocele wall

The doctors say theirs is only the second such case reported in an English-language medical journal.

The story of this patient’s asymptomatic ureteral stone went in a different direction after said stone spontaneously broke through the ureterocele wall.

According to doctors in Japan, the 67-year-old woman presented with pollakiuria and dysuria after a week of “gross haematuria”, although she denied any colicky pain.

She was previously diagnosed with an asymptomatic ureteral stone (1.0cm x 0.9cm) in the right intravesical single-system ureterocele, without hydronephrosis, after MRI and CT imaging.

Urinary analysis revealed mild microscopic haematuria without pyuria, while serum creatinine and haemoglobin levels were normal.
