  • first clinical evaluation of a new single use flexible cystoscope dedicated to Double J Stent removal isiris a european prospective multicenter study
    World Journal of Urology, 2017
    Co-Authors: Steeve Doizi, Guido M. Kamphuis, Jl Palmero, Guido Giusti, Jake Patterson, Silvia Proietti, M Straub, Jean J M C H De La Rosette, Olivier Traxer
    Abstract:

    We evaluated a new single-use digital flexible cystoscope with an integrated grasper designed for Double-J Stent removal, Isiris™, addressing success rate, image quality, deflection, maneuverability and grasper functionality. In September 2015, a prospective cohort study was conducted in six tertiary European reference centers. All consecutive patients included underwent Double-J Stent removal and were 18 years or older. Success rate was defined by complete Stent removal. Image quality, deflection, maneuverability and grasper functionality were rated with a Likert scale. A total of 83 procedures were performed. 82% of procedures were performed in the endoscopy room, while the others were in the operating room since a consecutive endourological intervention was planned. The median duration of Stent implantation was 28 days [14; 60]. In five patients, Stent removal was not possible. Four patients had an incrusted Double-J Stent, and in one patient, the Stent migrated into the ureter. After unsuccessful attempts of Stent removal with conventional flexible cystoscope and grasper, the five patients had to be scheduled for an ureterorenoscopy procedure to remove the Stent. In the other 78 patients, all Double-J Stents were removed successfully. Image quality, deflection, maneuverability and grasper functionality were rated as “very good” in 72.3, 78.3, 72.3 and 73.5%, respectively. This multicenter clinical evaluation of Isiris™ displayed good image quality, active deflection, maneuverability and grasper functionality. Further evaluation of Stent removal outcomes, cost analysis and microbiology will help to delineate the possible place of Isiris™ in the current practice.

  • the new grasper integrated single use flexible cystoscope for Double J Stent removal evaluation of image quality flow and flexibility
    World Journal of Urology, 2017
    Co-Authors: Silvia Proietti, Michele Talso, Esteban Emiliani, Mohammed Baghdadi, A Orosa, P Servian, A Barreiro, Olivier Traxer
    Abstract:

    A new single use digital flexible cystoscope (FC) Isiris α from Coloplast® with an incorporated grasper has been developed to perform Double J Stent removal. There is a lack of data regarding the comparison of image quality, flexibility and flow between classic cystoscopes and the new Isiris α. Five different FC were used to compare the image quality, the field of view, the loss of flow and the deflection loss. Two standardized grids, three stones of different composition and a ruler’s image were filmed in four standardized different scenarios. These videos were shown to thirty subJects that had to evaluate them. Water outflow was measured in ml/sec in all devices with and without the grasper inside, instruments tip deflection was measured using a software. In the subJective analysis of the image quality Isiris α was the second FC best scored. At 3 cm of distance, the field view of Isiris α was the narrowest. Comparing the water flow in the different FCs, we observed a water flow decrease in all cystoscopes when the grasper was loaded in the working channel. Isiris α deflection and flow increase when the grasper is activated. In terms of quality of vision and water flow, the FC Isiris α is comparable to the other digital FC tested. Field of view is narrower. The results displayed a valid alternative to the standard procedure for DJ removal.

  • migration of a Double J Stent into the inferior vena cava a case report
    Medicine, 2019
    Co-Authors: Changyi Jiang, Jian Chen, Yong Chen, Deqiang Chen, Prashant Mishra
    Abstract:

    INTRODUCTION Intravascular migration of a Double J Stent into the inferior vena cava is an uncommon complication. The management of such complication is less reported in the literature. This study aimed to reveal the diagnosis and treatment process of migration of a Double J Stent into the inferior vena cava. PATIENT CONCERNS A 53-year-old male patients was transferred to our hospital because of migration of a Double J Stent into the inferior vena cava after left-side pyelolithotomy. DIAGNOSIS In accordance with manifestations on computed tomography urography, the patient was diagnosed with migration of a Double J Stent into the inferior vena cava. INTERVENTIONS Percutaneous nephroscope under C-arm guidance was performed to remove the migrated Stent. After the operation, the patient was treated with continued anticoagulants and antibiotics. OUTCOMES The migrated Stent was removed successfully without any complications, and a new Double J Stent was placed and its location was confirmed under C-arm. The patient was discharged in good condition and the follow-up was uneventful. CONCLUSION Intravascular migration of a Double J Stent into the inferior vena cava is an uncommon complication. Radiologic imaging after placement of ureteral Stent is critical for prevention of this complication. Percutaneous nephroscope under C-arm guidance is a safe and effective approach to remove the migrated DJS in the IVC.
