Percutaneous extraction of intravascular foreign bodies with the help of specifically designed devices is the standard method of treatment and should be attempted in appropriate cases before any surgical approach. The majority of retrieved materials are catheter fragments localized in the superior vena cava, right side of the heart, or pulmonary artery. During diagnostic coronary angiography of...

INTRODUCTION Whereas a retrograde attempt to insert an indwelling stent is performed in lithotomy position, usually renal access is gained in a prone position. To overcome the time loss of patient repositioning, a renal puncture can be performed in a modified lithotomy position with torqued truncus and slightly elevated flank. There is a two-fold advantage of this position: transurethral and tr...

BACKGROUND Chronic total occlusions (CTOs) are associated with significant angina, impaired left ventricular function, and worse long-term outcomes. Percutaneous coronary interventions in CTO are unsuccessful in up to 50% of cases, primarily because of inability to cross the lesion with a guide wire. Collagen is the predominant component of the atherosclerotic plaque. The objective of this stud...

30 cases of obstructing proximal ureteral stones at the level of L3-L5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. Multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability...
