Purpose: Percutaneous aspiration with sclerotherapy is widely used as a treatment for simple symptomatic renal cysts because percutaneous aspiration with sclerotherapy is minimally invasive and cost-effective. Sclerotherapy is usually performed in combination with aspiration due to the high recurrence rate, 30-70%, for the simple aspiration. We conducted an analysis of percutaneous aspiration with repeated sclerotherapy, and we report the results of sclerotherapy after percutaneous aspiration of simple renal cysts and we also review the results of the other previous studies. Materials and Methods: Between January 2001 and April 2004, the results of percutaneous aspiration with repeated sclerotherapy in 39 cases of simple renal cysts were evaluated. We evaluated the operation time, the hospital stay, the success rate, the complication rate and the follow-up period. All patients were available for follow-up over a period of 3 months by conducting ultrasound exams and computed tomography (CT) scans. Results: Complete collapse, partial collapse and recurrence of the renal cysts occurred in 24/39 (61.5%), 13/39 (33.3%), and 2/39 (5.1%) cases, respectively. The mean operative time was 50.3 minutes and the mean hospital stay was 4.5 days. The cost of two sessions of sclerotherapy was about 240,000 won and that of three sessions of sclerotherapy was about 300,000 won. The size of the cyst was not related to the rate of collapse. Any complication related to percutaneous aspiration with repeated sclerotherapy were not noted. Conclusions: With regard for the success rate and cost-effectiveness, percutaneous aspiration with repeated sclerotherapy is considered a primary treatment for simple symptomatic renal cysts.

Objective To investigate the technique and clinical efficacy of percutaneous treatment of hepatic cyst by apiration and sclerotherapy.Methods Data of 28cases with hepatic cyst by percutaneous aspiration and sclerotherapy in our hospital were collected and analysed.Results Thirty six hepatic cysts in 28 patients underwent ultrasonography (20 cases) /CT(8 cases) guided percutaneous puncture and aspiration.All the cases received corresponding ethanol sclerotherapy according to the different quality of the cysts and were followed up.Compared with those presclerotherapy,the cysts reduced by less than 1/3 in 2 cysts,by 1/3-2/3 in 19 cysts,by more than 2/3 in 15 cysts and disappeared in 5 cysts after sclerotherapy.The treatment was effective in all the cases.After 6 months to 13 years followup,no fatal complications or recrudescent cases were found.Conclusion Percutaneous treatment of hepatic cyst by aspiration or drainage followed by ultrasonography /CTguided injection of alcohol is safe and effective.

Objective To evaluate the clinical value of percutaneous transcatheter sclerotherapy in oophoritic cysts. Methods Seventy six oophoritic cysts incluoling 48 simple and 28 chocolate cysts of 64 patients were treated with percutaneous transcatheter sclerotherapy under CT guidance.4F multisideholes pigtail catheter was introduced into cyst using absolute alcohol as sclerosing agents. Results The successful rate of percutaneous oophoritc cyst puncture was 100% in all 64 patients.Among them 58 were cured((90.6%)),6 improved significantly((9.4%)).The total effective rate reached 100% with no serious complications. Conclusions Catheterization sclerotherapy for oophoritic cyst is a simple,complete,safe and effective method.

Percutaneous sclerotherapy of varicocele was considered in 21 patients with left sided varicocele, 16 of whom had recurrences after left spermatic vein ligation in the past. Percutaneous sclerotherapy was possible in 17 patients (80.9%). There were no serious complications with venography or sclerotherapy, and the recurrence rate was 17.6%. Percutaneous sclerotherapy is therefore a simple, safe and effective treatment of testicular vein insufficiency.

Objective To evaluate the clinical efficacy of sclerotherapy of percutaneous catheter drainage for simple renal cysts.Methods Fifty-nine cases of renal cysts with percutaneous catheter drainage sclerotherapy were compared with 59 cases of percutaneous sclerotherapy.The differences of the cure rate and overall efficiency were analyzed.Results The cure rate of catheter drainage sclerosis group was significantly higher than that of pure sclerosis group(93.2% vs 61.0%,P 0.01);the total effective rate of catheter drainage sclerosis group was also significantly higher than that of pure sclerosis group(100% vs 79.7%,P 0.01).Conclusion The efficacy of the percutaneous catheter drainage sclerotherapy for simple renal cysts are significantly better than simple percutaneous sclerotherapy,and it is worthy of clinical application.

AIM: To investigate the efficiency of percutaneous treatment of hepatic cystic disease by aspiration or drainage followed by CT-guided injection of alcohol and to study the pathologic basis.METHODS: Eighty hepatic cysts in 57 patients underwent CT-guided percutaneous puncture and aspiration.All the cases received corresponding ethanol sclerotherapy according to the different quality of the cysts and were followed up.RESULTS: Compared with those pre-sclerotherapy,the cysts reduced by less than 1/3 in 6 cases,by 1/3-2/3 in 24 cases and disappeared in 27 cases after sclerotherapy.The treatment was effective in all the cases.After 6 months to 4 years follow-up,no fatal complications or recrudescent cases were found.CONCLUSION: Percutaneous treatment of hepatic cystic disease by aspiration or drainage followed by CT-guided injection of alcohol is safe and effective.

Objective To compare the image guided effect between CT and Ultrasound for percutaneous catheter drainage and sclerotherapy in the treatment of hepatic cysts.Methods 26 patients with hepatic cysts underwent percutaneous catheter drainage and sclerotherapy by CT guided.87 cases underwent percutaneous catheter drainage and sclerotherapy by Ultrasound guided.Results 53 cysts underwent percutaneous puncture with 132 times by CT guided,and 5 cysts underwent sclerotherapy were failed(10.1％).231 cysts underwent percutaneous puncture with 267 times by Ultrasound guided,and 5 cysts underwent sclerotherapy were failed(2.1％).The failed rate of the two groups had statistifically significant difference(x2 =39.6875,P ＜ 0.05).Conclusion In the image guided technique for percutaneous catheter drainage and sclerotherapy in the treatment of hepatic cysts,Ultrasound had more advantages,high accuracy,real time visual,high success rate,less damage,economy and convenience than CT.

The Authors describe their experience regarding 80 cases of selective phlebography of the spermatic vein in men with varicocele. Percutaneous transvenous retrograde sclerotherapy of the internal spermatic vein was performed in 78 patients (type 1 and type 3 according to Coolsaet). Follow-up colour-doppler 1 month after sclerotherapy revealed a persistent varicocele in only 3% of cases. The Authors present the advantages of percutaneous sclerotherapy.

The indications, techniques, complications and results of percutaneous sclerotherapy or embolization of gonadal veins for varicocele are discussed. Of our 93 patients, sclerotherapy of varicocele was technically possible in 81 cases. Sclerotherapy or embolization can be effected by different materials, such as: Histoacryl and Lipidiol mixed 1:2 to 1:4 and Aethoxysklerol, applied by a coaxial catheter system or end-opened F 6-catheter. Today the percutaneous transluminal sclerotherapy of gonadal veins is the treatment of choice for varicocele.
