Abstract
Objective To investigate the efficacy of 24-h interval multiple-session ethanol sclerotherapy for the treatment of simple renal cysts. Materials and Methods The study sample included 58 patients (mean age, 65.37 ± 11.95 years). We included 76 simple renal cysts that were treated with percutaneous aspiration with a minimum of two sessions of 95% ethanol sclerotherapy in a 24-h interval between sessions. Patients were evaluated at 1, 3, and 6 months after the intervention for the efficacy of the treatment. Treatment success was defined as a complete regression of a cyst or a > 50% reduction in its volume, with no recurrence of symptoms. Results The mean preprocedural cyst size was 72.98 ± 25.14 mm, and the mean preprocedural cyst volume was 205.76 ± 244.15 mL. The mean volume of ethanol used in the first sclerotherapy session was 62.76 ± 30.71 mL. The mean fluid accumulation in the cysts at the end of the first 24-h interval was 4.66 ± 7.13 mL. The mean quantity of ethanol used in the second sclerotherapy session was 26.48 ± 22.2 mL. A third sclerotherapy session was required in only 10 (13.2%) of the cysts. The mean follow-up period was 52.84 ± 37.83 months. The rate of complete regression was 97.4% for the whole sample at the end of the follow-up. Conclusion Ethanol ablation with 24-h intervals is a safe and effective treatment option in the minimally invasive percutaneous treatment of simple renal cysts.

Abstract
Simple renal cysts are common benign lesions of the kidney with up to 4% of patients developing symptoms necessitating intervention including pain and haematuria. We conducted a systematic review of the literature to determine the efficacy and safety of aspiration-sclerotherapy of symptomatic simple renal cysts. A systematic review using Cochrane guidelines was conducted on published literature from 1990 to 2020. RCTs, cohort studies and case series meeting the inclusion criteria were reviewed and cumulative analysis of outcomes was performed. A total of 4071 patients from 57 studies underwent aspiration ± sclerotherapy for their simple renal cysts. 87.7% of patients who had aspiration with sclerotherapy demonstrated 'treatment success' with a >50% reduction in cyst size and complete resolution of symptoms. 453 minor, transient complications occurred (11.2%) whilst a major complication rate of less than 0.1% (4 patients) was reported. Pooled analysis of all available current literature demonstrates that aspiration-sclerotherapy is a safe and effective first-line therapy for symptomatic simple renal cysts. Although we are unable to compare those undergoing aspiration alone to aspiration-sclerotherapy, it is evident the use of a sclerosing agent is integral to treatment success; however, the optimum agent, volume, injection frequency, and dwelling time are yet to be defined. Cyst size should be considered when discussing treatment options; however, we conclude it reasonable for aspiration-sclerotherapy to be used in the first instance in all cases of symptomatic simple renal cysts. Furthermore, we propose definitions of treatment outcome measures in order to allow direct comparative analysis across future studies.

Abstract
INTRODUCTION Simple kidney cysts are the most common type of benign kidney tumors in adults and they are usually asymptomatic. Symptomatic cysts are treated with percutaneous aspiration with or without sclerosing agent injection, laparoscopic decortication or with open surgery in rare cases. Considering the probable complications of anesthesia in open surgery and laparoscopic methods, we tend use an innovative method by percutaneous aspiration, inserting nephrostomy catheter for 24 hours and injection of sclerosing agents, leaving the agent inside the cyst while catheter is removed immediately. Long term results of this method were evaluated using sonography. METHOD AND MATERIALS Twenty-eight patients with symptomatic kidney cysts underwent the process of inserting the percutaneous catheter and aspiration of its contents in two steps and one-time injection of 95% ethanol. After the first aspiration, patients stayed admitted for 24 hours. Then, the second aspiration was performed and the total fluid volume was measured. Patients were then followed for a mean follow-up period of 14 months. The success of the procedure was considered as no signs of relapse (consistent with reduced size of the cysts) in sonographic evaluation of long-term results. RESULTS Among all the patients, 23 (82.14%) showed positive results in sonographic evaluation after 14 months. Death occurred in one patient (3.6%) not attributable to the procedure and recurrence was seen in 5 patients (17.9%). CONCLUSION Our study showed that this method is safe, effective and minimally invasive in treating simple kidney cysts and can be a proper substitute for the other current methods.

Abstract
Renal sympathetic denervation using conventional non-irrigated radiofrequency catheters has potential technical shortcomings, including limited penetration depth and incomplete circumferential nerve damage, potentially impacting therapeutic efficacy. Against this background, second generation multi-electrode, radiofrequency and ultrasound renal denervation systems have been developed to provide more consistent circumferential nerve ablation. Irrigated catheters may allow deeper penetration while minimizing arterial injury. In this context, catheter-based chemical denervation, with selective infusion of alcohol, a potent neurolytic agent, into the perivascular space, may minimize endothelial, intimal and medial injury while providing circumferential neurolysis. Animal studies demonstrate pronounced renal norepinephrine level reductions and consistent renal nerve injury after perivascular alcohol infusion using the Peregrine Catheter. Early clinical studies demonstrated significant blood pressure reductions and a reasonable safety profile. Randomized sham-controlled trials (NCT03503773, NCT02910414) are underway to examine whether the aforementioned theoretical advantages of alcohol-medicated denervation with the Peregrine System™ Kit translate into clinical benefits.

Abstract
Background: Percutaneous aspiration with sclerotherapy (PAS) and laparoscopic marsupialization (LM) are minimally invasive treatment modalities for renal cysts. We aimed to compare the efficacy and cost/effectiveness of LM and PAS for the treatment of simple symptomatic renal cysts. Methods: Data were prospectively collected from three health care institutions in which 80 patients with symptomatic simple renal cysts underwent a single session of PAS with 95% ethanol (PAS group, n = 40) or underwent LM under general anesthesia (LM group, n = 40) between March 2012 and May 2016. We compared the patient profile, duration of procedure, duration of hospital stay, radiological and symptomatic success rates, treatment costs, and incidence of complications between the two groups. Results: At the 6-month follow-up, the radiological success rate in the LM group was significantly greater than that in the PAS group (97.5% versus 60%; P < .001). The symptomatic success rate was comparable in the two groups (95% versus 90%; P = .675). The treatment failure rate did not significantly differ between the two groups (5.0% versus 17.5%, P = .154). The mean total cost in the PAS and LM groups was 1256 USD and 2343 USD, respectively (P = .001). No significant between-group difference was noted regarding the overall complication rate (P = .615). Conclusions: Both LM and PAS are effective and safe procedures for the treatment of symptomatic simple renal cysts. A single session of PAS seems to be a cost-effective method for the management of symptomatic simple renal cysts.

Abstract
Objective: The aim of this study was to evaluate the efficacy and safety of ultrasound guided percutaneous sclerotherapy of symptomatic simple renal cysts with n-butyl cyanoacrylate (NBCA) and iodized oil mixture as an outpatient single session procedure. Materials and Methods: A total of ninety two patients with 100 symptomatic simple renal cysts (larger than 5 cm) were treated by ultrasound (US)-guided percutaneous aspiration and injection of NBCA and iodized oil mixture. The patients (68 men and 24 women, mean age, 42.4 ± 10.5 years) were treated with as out-patients. The volume of the treated cysts was calculated with periodic noncontrast enhanced CT examinations 3, 6 and 9, months after the procedure. The procedure was considered successful at follow-up CT when there was total ablation or greater than 80% reduction of size with resolution of symptoms, respectively. Failure was defined as less than 80% reduction and/or persistent symptoms. Results: The sclerotherapy was technically successful in all patients. The diameter of the cysts ranged between 5.5 and 13.5 cm (mean, 8.8 ± 1.4 cm), and 1.5 and 3.8 cm (mean, 2.1 ± 0.4 cm) before and after sclerotherapy, respectively (P < 0.001). Average diameter reduction was 83.7% during the follow-up period. The mean follow- up lasted 7.1 months (3–11 months). Flank pain resolved in 86 of 92 symptomatic patients (93.48%). In six patients, the symptoms decreased slightly. The procedure was successful in 98 of 100 cysts (98%), demonstrated by follow-up CT. The only two failed cyst was larger than 10 cm in diameter and don’t required any further treatment. We did not observe any procedure related complications. Conclusion: Ultrasound guided percutaneous sclerotherapy with NBCA and iodized oil mixture for management of symptomatic simple renal cysts was found to be a real time, effective, safe, well tolerated, alternative and simple technique that can be carried out by urologists as an outpatient procedure.

Abstract
AIM In this study, we compared and valued efficacy and safety of percutaneous echoguided sclerotherapy (PES) using 3% polidocanol with that using 99% ethanol in the treatment of patients with simple renal cysts. MATERIALS AND METHODS PES was performed for 65 simple renal cysts. Under ultrasonographic guidance the cyst was punctured using an 18 gauge needle. Sclerotherapy was performed with ethanol in 55% (36/65) of cases and with polidocanol in the remaining 45% (29/65). Patients were followed up with an ultrasound examination at 4 months, 8 months, and then at yearly intervals. A reduction of 50% or greater in cyst diameter was considered successful. RESULTS The median followup period for the ethanol and polidocanol groups was 24.6 and 22.8 months, respectively. The successful outcome ratio of the polidocanol group was significantly higher (90% vs. 61%, respectively) than the one of the ethanol group (P = 0.003). The partial regression of the ethanol and polidocanol groups were 6% versus 7%, respectively. The failure ratio of the polidocanol group was significantly lower (3% vs. 33%, respectively) than that of the ethanol group (P = 0.004). Neither infectious complications nor hyperthermia occurred in all treated cases. However, these methods are not completely free from symptoms. All these symptoms disappeared few hours after the procedure. CONCLUSIONS Polidocanol is a safe and effective sclerosing agent for renal cysts, with superior clinical results than ethanol. Therefore, polidocanol can be an alternative to ethanol in sclerotherapy of renal cysts.

Abstract
OBJECTIVES To compare the efficacy and safety of ethanolamine oleate (EO) as a sclerosing agent, vs. absolute ethanol (AE), in the treatment of symptomatic simple renal cysts. PATIENTS AND METHODS Between November 2009 and October 2012, 46 patients were prospectively randomised into two groups. All patients presented with a simple renal cyst underwent ultrasonographic aspiration and injection of a sclerosing agent. In group 1, 25 patients had the cyst injected with EO, and in group 2, 21 were treated with AE. One injection was used in cysts of <200 mL and two injections were used in larger cysts. Complete and partial success were defined as complete cyst ablation or a >50% reduction in cyst volume with symptomatic relief, respectively. Patients were followed up using semi-annual ultrasonography and computed tomography for 2 years. RESULTS Sclerotherapy was technically successful in all patients. There was no significant difference in cyst volume between the groups. After ≈2 years of follow-up there was complete symptomatic relief in both groups, and the overall radiological success rate was 100% of both groups, at 79% complete and 21% partial in group 1, and 83% complete and 17% partial in group 2. The frequency of transient complications in the form of microscopic haematuria was 7% and 13%, and of low-grade fever in 4% and 10% in groups 1 and 2, respectively. CONCLUSION EO can replace AE as a sclerosing agent for symptomatic simple renal cysts, as it has comparable efficacy with higher safety and tolerance.

Abstract
PURPOSE To evaluate the efficacy and safety of single-session OK-432 sclerotherapy for the treatment of renal cysts. MATERIALS AND METHODS From October 2005 to November 2006, 48 patients (61 simple renal cysts) were included in the study. Indications were determined as flank discomfort (n = 37) or patient reassurance due to increasing size (n = 11). The simple renal cysts were aspirated under ultrasonography (US), at which point OK-432 was injected into the cyst. Follow-up was performed with US or computed tomography scan every 3 months until 1 year. Complete regression of the renal cyst or more than 70% reduction in size with no symptoms indicated a successful treatment. RESULTS Among 61 renal cysts of 48 patients, the overall success rate was 98.4%. Complete regression occurred in 46 cysts (75.4%), and more than 90% reduction in size occurred in 6 cysts (9.8%). A size reduction of 80% to 90% and 70% to 80% occurred in five (8.2%) and three cysts (4.9%), respectively. A size reduction less than 70% occurred in only one cyst (1.6%). The success of cyst regression was correlated with cyst volume. Clinical symptoms resolved in 100% of patients with symptomatic cysts, and there was no enlargement of the aspirated cysts at the 1-year follow-up. After the procedure, there were only some minor complications, such as mild fever, flank pain, and leukocytosis, which subsided with the conservative treatment. CONCLUSIONS Percutaneous OK-432 sclerotherapy is simple, safe, and effective, and it can be an alternative first-line therapy for simple renal cysts.

Abstract
OBJETIVO: Demonstrar a eficácia e os resultados práticos da alcoolização percutânea de pacientes com cistos renais simples sintomáticos. MATERIAIS E MÉTODOS: Foram revistos os resultados obtidos em dez pacientes com cistos renais simples sintomáticos (oito homens e duas mulheres), com idade entre 28 e 72 anos (média de 55 anos), submetidos a pelo menos duas alcoolizações percutâneas. A indicação do procedimento foi dor no flanco refratária nos dez pacientes, sete deles com algum grau de hidronefrose pela localização parapiélica do cisto. O volume aspirado variou entre 20 e 1.300 ml (média de 200 ml). O tempo médio de seguimento após o procedimento foi de sete meses. O procedimento foi dirigido por ultrassonografia em dois casos e por tomografia computadorizada em oito. O tempo de internação variou entre 24 e 72 horas. Foi considerado sucesso completo do tratamento o desaparecimento do cisto, e parcial a redução maior que 50%. RESULTADOS: Durante o seguimento houve redução completa do cisto em sete pacientes e redução parcial em três. Em nenhum caso foram registradas complicações e os pacientes toleraram bem o procedimento. CONCLUSÃO: A alcoolização percutânea de cistos renais sintomáticos é um procedimento seguro, efetivo e pouco invasivo e com resultados semelhantes aos obtidos por outros autores.

Abstract
The aim of this study was to evaluate the results of percutaneous drainage with single-session alcohol sclerotherapy in the treatment of symptomatic simple renal cysts. Thirty patients (16 men and 14 women, average age 54,7+/-11,3 years) with simple renal cysts were treated by ultrasound guided percutaneous aspiration and single-session alcohol sclerotherapy. Patient demographics, clinical characteristics, treatment outcome and complications were analyzed. Average reduction of cyst volume was 91,2%. Complete and partial resolution occurred in 10 (33%) and 14 (47%) cysts, respectively. Six cases were defined as failure with reduction of cyst volume <80%. Flank pain improved in all patients, regardless of complete or partial resolution. Minor complications occurred in 8 patients. The hospital stay was one day for all patients. Treatment of simple renal cysts is indicated when the cysts are sufficiently large and cause complaints or when associated with complications. Percutaneous treatment with alcohol sclerotherapy of benign renal cysts can be performed safely and effectively.

Symptomatic simple renal cyst: comparison of continuous negative-pressure catheter drainage and single-session alcohol sclerotherapy. AJR Am J Roentgenol 2008; 190:1193-7.

Abstract
OBJECTIVE The purpose of this study was to evaluate whether continuous percutaneous catheter drainage with negative pressure yields better results than single-session alcohol sclerotherapy in the management of symptomatic simple renal cysts. SUBJECTS AND METHODS Eighty-five patients with 92 simple renal cysts were randomly assigned to two groups in a prospective controlled trial. One group was treated with sonographically guided continuous catheter drainage with negative pressure and the other group with single-session alcohol sclerotherapy. Patient demographics, clinical characteristics, treatment outcome, and complications were analyzed. RESULTS The initial volume of the cysts did not differ significantly between the groups, but the final volume was significantly smaller in the continuous drainage group (p = 0.026). During the 24-month follow-up period, 37 (40%) of the cysts disappeared completely: 24 (52%) of the 46 cysts in the drainage group and 13 (28%) of the 46 cysts in the sclerotherapy group (p = 0.033). In the sclerotherapy group, the probability of disappearance of the cysts was highly dependent on cyst size, being less for giant cysts (p = 0.01). Cyst size was not a significant factor in probability of disappearance in the drainage group (p = 0.15). The probability of disappearance of giant cysts (volume > 500 mL) differed significantly between the groups (p = 0.009), but there was no difference in probability of disappearance of moderately large cysts (p = 0.16). Three of 14 patients with giant cysts in the drainage group and 10 of 13 such patients in the sclerotherapy group had recurrences that necessitated additional treatment (p = 0.007). They were successfully treated with continuous catheter drainage. CONCLUSION Continuous catheter drainage with negative pressure is more efficient than single-session alcohol sclerotherapy in the management of giant cysts. For moderately large cysts, the two methods have similar results.

Abstract
OBJECTIVE We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. MATERIALS AND METHODS A prospective series of 74 consecutive patients (average age: 57.6 +/- 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. RESULTS The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. CONCLUSION Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.

Abstract
OBJECTIVES Symptomatic simple renal cysts can be treated by combination of percutaneous aspiration and sclerotherapy. A number of sclerosing agents including glucose, phenol, iophendylate, polidocanol, minocycline and pantopaque have been used in the past to prevent reformation of cyst. In this study, tetracycline HCL solution is evaluated as a sclerosant for treatment of simple renal cysts. METHODS Our study treated 76 cysts in 70 patients with symptomatic renal cysts. Aspiration and sclerotherapy was performed on 56 cysts, and 20 cysts aspirated without sclerotherapy as a control group. Treatment was performed under local anesthesia and punctured under ultrasound guidances with an 18-gauge needle. Tetracycline HCL (20%) was injected into the cystic cavity according to cyst diameter. All patients were followed up with an ultrasound examination at 3 months, 6 months, and then at yearly intervals. The reduction rate was estimated by a comparison of the volume of the cyst before and after treatment. A cyst reduction of 50% or greater in diamater was considered as a successful treatment. RESULTS The average follow-up period was 9.8 months in the sclerotherapy group and 9.9 months in the control group. The success rate was 85.7% in the sclerotherapy group. There was a significant difference in the reduction rate of tetracycline HCL sclerotherapy group and control group. No major complications were encountered.

Abstract
PURPOSE The aim of this study was to demonstrate OK- 432 sclerotherapy efficacy for treatment of simple renal cysts. MATERIALS AND METHODS Twenty patients with 25 symptomatic or large simple cysts were treated by ultrasonography (US)-guided percutaneous aspiration and injection of OK-432 (8 men and 12 women, mean age 63.6 years, SD 9.5). Six patients presented with flank pain, 14 presented with renal mass; renal cyst location was right, left, or bilateral sided in 9, 8, and 8 kidneys, respectively. Patients were evaluated by clinical assessment, US, or CT scan 3 months following the procedure. Complete and partial success was defined as symptom resolution with either total cyst ablation or greater than 70% reduction, respectively. Failure was defined as 30% of cyst size recurrence and/or persistent symptoms. RESULTS Average reduction was 93.0%. Complete and partial resolution occurred in 11 (44.0%) and 13 (52.0%) cysts, respectively. One case was defined as failure, with a 64.2% size reduction from 10.9cm to 3.9cm (volume reduction rate 95.4%). Renal pain improved in all patients, regardless of complete or partial resolution. Minor complications occurred in 3 patients, 2 developed leukocytosis and 1 had mild fever (< 38.5 degrees C) following aspiration and sclerotherapy. Successful treatment was achieved with conservative measures and NSAID therapy. CONCLUSION Percutaneous treatment of simple renal cysts with OK-432 sclerotherapy was found to be a safe, effective and minimally invasive procedure.
