Removal of a Retained Percutaneous Nephrostomy Balloon Catheter Using a Trocar Needle: A Case Report.

While non-deflating Foley catheters are a well-known complication, non-deflating nephrostomy balloon catheters have rarely been reported. We report the case of a 76-year-old man with a non-deflating nephrostomy balloon catheter. To treat this condition, a 19-gauge trocar needle included in an 8.5-F drainage catheter was inserted through the urinary lumen of the catheter to puncture the balloon. The balloon was then deflated, and the nephrostomy catheter was exchanged. Balloon puncture using a trocar needle may be a suitable technique for removing non-deflating nephrostomy balloon catheters.
