The ole of Choice-Lck Catheter and Trocar Technique in Percutaneous Ablation of Symptomatic Renal Cysts

Abstract

Background:The most common benign lesions of the kidney are simple cysts. They are acquired lesions and mostly affect the elderly population.Objectives:To describe the usage of choice-lock catheter and trocar technique in percutaneous renal cyst treatment and determining long-term outcomes.Patients and Methods:This retrospective study was carried out between February 2000 and July 2011. Eighty-eight cysts all of which were Bosniak type-1 cysts were selected in 75 patients. The treatment indications were flank pain, hydronephrosis and hypertension. The choice-lock catheter was used for 84 cysts with the trocar technique. Ninety-five percent ethanol was used as the sclerosing agent. Maximum volume of the injected ethanol was 175 ml. The mean follow-up time after the treatment procedure was 23 months. Sixty-four cysts were located in the cortical and 24 cysts were located at the parapelvic region.Results:Fifty-seven cysts had complete regression, while 31 cysts regressed partially. After the procedure, pain was relieved in 44 (82%) patients and the pain alleviated in four (8%). Normotension was obtained in five (62.5%) of the eight hypertensive patients and no hydronephrosis was detected in nine patients. There were no relationship between the localization and the regression rate. No major complications occurred.Conclusions:Percutaneous ethanol sclerotheraphy in simple cysts is a safe, cost-effective and minimally invasive method. We consider that this technique may be an alternative solution in the percutaneous cyst treatment.

Pediatric percutaneous urologic procedures in interventional radiology

“…Kist duvarındaki epitelyum aktif sıvı üretiminden sorumludur ve rekürrensi önlemek amaçlı kist duvarı yok edilmelidir (12,14) . Etanol, asetik asit, tetrasiklin, minosiklin, betadin, %50 glukoz solüsyonu ve OK-432 kullanılan sklerozan maddelere örnektir (12)(13)(14)(15)(16) . Asetik asit en etkili ajanlardan biridir, ancak alkol daha güvenilir olup, daha yaygın kullanılmaktadır.…”

“…İşleme bağlı komplikasyonlar düşük düzeydedir; yan ağrısı, kist içine kanama en sık görülen komplikasyonlar olup kontrol altına alınabilirler (11,14,16) .…”

Comparative analysis of surgical treatment outcomes in children with solitary renal cysts

“…Несмотря на минимальную инвазивность пункционных методов, рецидивирование кисты возникает в 80-90% случаев [17]. Помимо пункции в полость кисты вводят склерозирующие растворы, в последующем их дренируют с поэтапной санацией [18,19,20]. Однако и при использовании склерозирующих растворов частота рецидивов кист остаётся высокой и, по данным одних авторов, она варьирует от 12,5 до 33% [21,22,23], а по данным других авторов частота осложнений после пункции и склерозирования кист почек достигает 40-60% [24,25].…”
