Introduction We aimed to investigate irrigation and drainage characteristics of commercially available urethral catheters and determined which catheter offers the best flow characteristics. Material and methods Twelve different commercially available urethral catheters from three companies (Bard™, Rusch™ and Dover™) were investigated to compare their irrigation and drainage properties. Irriga...

OBJECTIVE The thromboembolic events during neuroendovascular therapy (NET) are the major complications of concern that can be occasionally fatal. The thrombotic occlusion of the guide catheter for NET is thought to be the risk of the thromboembolic events. We have developed an idea for inventing the monitoring system of the continuous irrigation through the guide catheter. We herein present a u...

INTRODUCTION The management of purulent flexor tenosynovitis of the hand consists of surgical debridement followed by antibiotic treatment. Usually, the debridement is carried out by irrigating the tendon sheath in a proximal to distal direction facilitated by two small incisions. It is unclear whether intraoperative irrigation by itself is adequate for healing or if it should be combined with ...

Background: Dry radiofrequency (RF) ablation is an established form of surgical treatment of atrial fibrillation and many groups have reported good clinical results . One limiting factor of this type of ablation is that transmural lesions are not consistently obtained . Several reports on percutaneous ablation have shown that catheter irrigation leads to larger volume lesions than nonirrigated ...

A perirectal abscess is a relatively common disease entity that occurs as a postsurgical complication or as a result of various medical conditions. Endoscopic ultrasound (EUS)-guided drainage was recently described as a promising alternative treatment. Previous reports have recommended placement of a drainage catheter through the anus for irrigation, which is inconvenient to the patient and car...

Radiofrequency catheter ablation (RFCA) is a routine treatment for cardiac arrhythmias. During RFCA, the electrode-tissue interface temperature should be kept below 80 °C to avoid thrombus formation. Open-irrigated electrodes facilitate power delivery while keeping low temperatures around the catheter. No computational model of an open-irrigated electrode in endocardial RFCA accounting for both...

Background Use of irrigation catheters increases the power supply energy to create transmural injury [Jais P., Shah D.C., Haissaguerre M. et al., 2000]. However, these data are based on the catheter procedures and concomitant monopolar endocardial ablation [Deneke T., Khargi K. et al., 2007]. The benefits of using irrigation during bipolar concomitant ablation has no reflection in the literature.

We herein report a case of a renal pelvic tumor that developed in the residual left renal pelvis after right nephroureterectomy, left ureterectomy and total cystectomy in a patient with multiple urothelial tumors. The tumor was endoscopically ablated through a nephrostomy tract, and mitomycin C irrigation was carried out. We designed a novel constant-pressure irrigation system for effective and...

BACKGROUND One of the safety concerns when performing electrophysiological (EP) procedures under magnetic resonance (MR) guidance is the risk of passive tissue heating due to the EP catheter being exposed to the radiofrequency (RF) field of the RF transmitting body coil. Ablation procedures that use catheters with irrigated tips are well established therapeutic options for the treatment of card...

Unrecognized severe pseudomembranous colitis may become life threatening. A typical Clostridium difficile infection is associated with involvement of the colon; however, small bowel disease has also been described. Here, we present a case of a 48-year-old man with Clostridium difficile colitis of an isolated segment in the descending colon treated by a novel catheter intraluminal antibiotic irr...
