Long-term outcome of secondary endopyelotomy after failed primary intervention for ureteropelvic junction obstruction

Objective:  To evaluate the long‐term outcome of secondary endopyelotomy after failed primary intervention for uretero‐pelvic junction (UPJ) obstruction and to assess the effect of preoperative parameters on treatment outcome.

Paradoxical air embolism during percutaneous nephrolithotomy: a case report.

Air embolism is a rare complication of percutaneous nephrolithotomy. Patent foramen ovale, which is necessary in fetal circulation, is a potential route for emboli arising from the venous system to enter the systemic arterial circulation, resulting in paradoxical air embolism syndrome. A case of paradoxical air embolism during percutaneous nephrolithotomy is presented. To our knowledge, this is the first report of paradoxical air embolism associated with patent foramen ovale during percutaneous nephrolithotomy.
