Aim: To evaluate the efficacy of a new sclerotization technique with pure ethanol in the treatment of symptomatic renal cysts. Patients and Methods: Fourteen patients having renal cysts with a meant diameter of 10 (range 5–15) cm were treated. Our technique includes: ultrasound-guided percutaneous puncture with an 18-gauge needle, positioning of a 5-Fr catheter, complete cyst fluid aspiration, injection of pure alcohol equal to 15% of the initial cyst volume, and alcohol aspiration after 90 min. The procedure was repeated eight times within 5 days. The patients were followed up by ultrasound and/or CT scan for 1 year. Results: All patients became symptom free. Follow-up showed a progressive reduction of the cyst diameter in all cases. Three cysts only (in 2 patients; cyst diameter <2 cm) persisted after 12 months. No significant complications were observed. Conclusions: In our experience, injections of pure ethanol in renal cysts, repeated after some days, were effective in eliminating recurrences and related symptoms. The procedure was not associated with significant complications. Our findings suggest that it be considered the first-choice procedure in the treatment of renal cysts, due to the good results and the low cost of ethanol.

“…To overcome the drawbacks associated with the use of alcohol as a sclerosing agent, various other sclerosing agents have been employed for the complete single-session ablation of renal cysts, but no satisfactory long-term results have yet been documented (12-16). There have been several encouraging reports on the use of low-energy electron-emitting radionuclides in the local radiation treatment of small tumors and in radionuclide synovectomy (17-25).…”

ObjectiveTo evaluate the usefulness of a beta-emitting radionuclide (holmium-166-chitosan complex) as a sclerosing agent for the treatment of renal cysts.Materials and MethodsUsing 10-30 mCi of holmium-166-chitosan complex, 20 renal cysts in 17 patients (14 male and 3 female patients, ranging in age from 47 to 82 years) were treated by percutaneous sclerotherapy under ultrasonographic guidance. The volume of the cysts before and after the sclerotherapy and the percentage change in volume were calculated in order to evaluate the response to therapy, which was classified as either complete regression (invisible), nearly complete regression (< 15 volume% of initial volume), partial regression (15-50 volume%) or no regression (> 50 volume%).ResultsThe follow-up period ranged from 6 to 36 months (mean 28 months). Eighteen cysts (90%) regressed completely (n=11, 55%) or near-completely (n=7, 35%). Partial regression was obtained in one patient (5%) and there was no regression in one patient (5%). No significant complications were encountered.ConclusionThe holmium-166-chitosan complex seems to be useful as a new painless sclerosing agent for the treatment of renal cysts with no significant complications.

“…Many agents have reportedly been used for this purpose, including glucose, phenol, ethanol, iophendylate, morrhuate sodium, lipidol, povidone-iodine, tetracycline, n -butyl cyanoacrylate, laureth 9 (also called polidocanol), and bismuth phosphate [7,8]. Although short-term success was high, the limitations of this technique included a high cyst recurrence rate (54%) and the risk of collecting system strictures as a result of scarring caused by the sclerosing agent, making this technique ill advised for cysts located in the peripelvic region [9].…”

PurposeTo assess the efficacy of percutaneous unroofing in the treatment of simple renal cysts instead of laparoscopic decortication and open surgeries.Materials and MethodsFrom November 2009 to October 2010 at our department, 11 patients with 12 simple cyst units were managed by percutaneous unroofing. All cysts were evaluated with ultrasonography and abdominal computed tomography. If there were no contraindications, cyst wall resection was performed. A standard transurethral resectoscope was used to resect the cyst wall, and the parenchymal portion of the cyst was subsequently cauterized. The drain was left in place for 2 days.ResultsAt the 5-month follow-up, patients were asked about their symptoms and ultrasonography was performed. From 12 cyst units, 8 were completely resolved, 3 were reduced to less than 50%, and 1 was persistent to near its original size. Success was defined as a more than 50% reduction in cyst volume.ConclusionsSimple renal cysts can be safely managed by percutaneous unroofing with a success rate of more than 90%. This technique can offer several advantages over open surgery, such as decreased length of hospital stay, improved convalescence, and reduced risk of complications. Percutaneous resection also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.
