title: [Percutaneous kidney cyst sclerosing].
abstract: METHODS
  In the period between January 1986 and July 1990, 28 patients with renal cysts varying in size between 3 and 12 cm were treated with percutaneous sclerotherapy. Results, complications and further course were recorded and submitted to retrospective analysis.
  
  
  METHODS
  After ultrasound--controlled puncture of the cyst under local anesthesia, contrast medium is initially instilled in order to check the position of the needle and to exclude a tumor or calyceal cyst. After emptying the cyst, 96% ethanol was instilled and, after a delay of 1 to 2 minutes, completely aspirated again.
  
  
  RESULTS
  No complications were observed; in only one of the 27 patients followed up did a recurrence occur. In all other cases, an average regression of the cyst of 98% of the initial volume was achieved.
  
  
  CONCLUSIONS
  Percutaneous sclerosing of renal cysts is an unproblematical, low-invasive, non-stressful technique that is indicated as the treatment of choice in the case of renal cysts associated with clinical symptomatology.
