Cryoablation of lung malignancies recurring close to surgical clips following surgery: Report of three cases.

Background: Minimally ablative therapies are now available for the treatment of lung malignancies. However, selection of the appropriate technique is not always easy and requires accurate preoperative planning.

Aims: To describe the treatment of lung tumors with cryoablation.

Bilateral transrenal ureteral occlusion by means of n-butyl cyanoacrylate and AMPLATZER vascular plug.

AMPLATZER vascular plug is a widely used embolic agent. In the present paper, we present a case of an 86-year-old female patient who underwent bilateral ureteral occlusion by means of AMPLATZER vascular plug II coupled to n-butyl cyanoacrylate (NBCA) because of recurring pyelonephritis following cystectomy with subsequent bilateral ureterosigmoidostomy (sec. Mainz type II).

Retrograde fluoroscopy-guided trans-urethral exchange of ureteral stents: Comparison of direct grasping vs. modified snare.

Background: Several different techniques including guide-wire lasso, simple snare, modified snare (MS) and direct grasping (DG), are available for retrograde ureteral stent retrieval and exchange. Choice among them is not always easy and depends on many different factors, including the local level of expertise.

Objective: To compare the MS and DG during retrograde exchange of double-J ureteral stent under fluoroscopic guidance.
