Rupture of a Calyceal Diverticulum Secondary to Ureteroscopy: A Rare Complication

Abstract EN

We present a case of a 45-year-old female who experienced rupture of a right calyceal diverticulum caused by ureteroscopy.

Fifteen hours after the operation, she had severe right flank pain and a high fever (38.9°C).

Computed tomography revealed perinephric extravasation of urine and bleeding inside the diverticulum.

We diagnosed rupture of a calyceal diverticulum; therefore, we continued antibiotic administration and pain relief medication.

She became afebrile on postoperative day 4 and was discharged from the hospital on postoperative day 7.

Owing to renal cortex thinning in the diverticula, ureteroscopy is associated with a risk of rupture of calyceal diverticula.
