Herein we report on the results of 171 out of 214 patients with renal cysts. In 127 cases diameter of cyst being less than < 6 cm, was monitored repeating renal ultrasound every 6 months: 78 patients underwent pecutaneous cyst echoguided puncture, while 9 patients were treated as follows: 4 by open surgery, 3 by laparoscopy and 2 by percutaneous treatment in general anaesthesia. Cysts are classified in 4 types and therapy is different according to Bosniak's classification. When the cyst is less than 6 cm in diameter and symptomatology is absent, we follow the patients up with yearly ultrasound. In our experience cyst sclerotization is carried out by injecting either ethanol or Trombovar or 50\% glucose in water alone or associated with 2\% Aethoxysclerol. The best results are obtained from the use of ethanol (30\% of the volume of cyst). However some relapses are encountered after this kind of procedure. In these cases it is helpful to examine the cystic wall because of the presence of intracystic septa. Percutaneous treatment by means nephroscopy permits to visualize the cystic wall but it is not able to perform a biopsy of its wall. Laparoscopic treatment is performed by inserting 5 trocars with the patient under general anaesthesia. This technique is able to localize and biopsy the cystic wall without causing side-effects or complications. Open surgery was performed only in 4 patients affected with hidatid cyst. At present echoguided cyst puncture permits to approach the renal not complicated cysts, while laparoscopy constitutes a safe treatment in the case of benign recurrent and complicated cysts.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Herein we report on the results of 171 out of 214 patients with renal cysts. In 127 cases diameter of cyst being less than < 6 cm, was monitored repeating renal ultrasound every 6 months: 78 patients underwent pecutaneous cyst echoguided puncture, while 9 patients were treated as follows: 4 by open surgery, 3 by laparoscopy and 2 by percutaneous treatment in general anaesthesia. Cysts are classified in 4 types and therapy is different according to Bosniak's classification. When the cyst is less than 6 cm in diameter and symptomatology is absent, we follow the patients up with yearly ultrasound. In our experience cyst sclerotization is carried out by injecting either ethanol or Trombovar or 50\% glucose in water alone or associated with 2\% Aethoxysclerol. The best results are obtained from the use of ethanol (30\% of the volume of cyst). However some relapses are encountered after this kind of procedure. In these cases it is helpful to examine the cystic wall because of the presence of intracystic septa. Percutaneous treatment by means nephroscopy permits to visualize the cystic wall but it is not able to perform a biopsy of its wall. Laparoscopic treatment is performed by inserting 5 trocars with the patient under general anaesthesia. This technique is able to localize and biopsy the cystic wall without causing side-effects or complications. Open surgery was performed only in 4 patients affected with hidatid cyst. At present echoguided cyst puncture permits to approach the renal not complicated cysts, while laparoscopy constitutes a safe treatment in the case of benign recurrent and complicated cysts.(ABSTRACT TRUNCATED AT 250 WORDS)Pubblicazioni consigliate
