Ultrasound controlled kidney cyst puncture: significance for diagnosis and therapy

Renal cyst puncture under ultrasonic guidance has proved an excellent and safe method in the differential diagnosis of cystic renal masses. The use of ultrasound in the follow-up of patients with renal cyst puncture is mandatory for evaluation of complications and results. The therapeutic success of renal cyst puncture is poor and estimated at about 25%. New percutaneous techniques with resection of the cystic wall lead us to expect much better results than with open surgical management.
