Ultrasound followup of renal cyst puncture

The place of ultrasound and cyst puncture in the evaluation of renal masses is reviewed. Complications of cyst puncture, although rare, do occur. A review of 16 cases of renal cyst puncture revealed only 2 minor complications: in 1 case a pericystic hemorrhage occurred and in 1 case an intracystic hemorrhage was detected. Both complications were asymptomatic and detected by ultrasound. Ultrasound has proved to be an excellent means of followup for renal cyst puncture.
