[Percutaneous management of perinatal spontaneous rupture of a calyceal diverticulum].
We report a case of spontaneous rupture of a calyceal diverticulum in a perinatal woman who was treated with percutaneous procedure. A 28-year-old woman, who delivered a full-term healthy male infant 13 days prior to hospitalization, was admitted complaining of left progressive severe flank pain. Kidney-urethra-bladder X-ray showed a space-occupying lesion in the lower pole of the left kidney. Drip intravenous pyelography revealed the left renal pelvis and calyx to be pushed up. Renal computed tomographic scan demonstrated a cystic lesion in the lower pole of the left kidney with a perirenal hematoma. After percutaneous puncture followed by indwelling of 8 Fr. balloon catheter within the cystic lesion for drainage, the patient recovered dramatically. Retrograde and antegrade pyelography showed the cystic lesion communicating with an adjacent calyx in the lower pole of the left kidney. The physiological relationship to pregnancy is discussed as a possible etiological factor in the unique occurrence of this rare rupture, and the literature is reviewed.
