Summary
A retained suture from a nephrostomy tube can lead to kidney stone formation. This case highlights the importance of complete suture removal after percutaneous nephrostomy procedures to prevent complications.
Area of Science:
- Urology
- Interventional Radiology
- Nephrology
Background:
- Percutaneous nephrostomy (PCN) is a common urological procedure with expanding indications.
- Modern PCN catheters feature self-retaining loops secured by sutures to prevent dislodgement.
- Accidental dislodgement is a concern, leading to advancements in catheter design.
Observation:
- A case is presented involving a patient who underwent a percutaneous nephrostomy procedure.
- The nephrostomy tube utilized a self-retaining loop design secured by a locking suture.
- The locking suture was not completely removed post-procedure.
Findings:
- The retained suture fragment served as a nidus for calcification within the renal pelvis.
- This calcification represents a potential complication of incomplete suture removal.
- The case underscores a rare but significant issue in PCN management.
Implications:
- Complete removal of all components of the nephrostomy catheter system, including securing sutures, is crucial.
- Awareness of this complication may prompt enhanced vigilance during post-PCN care.
- This finding emphasizes the need for meticulous technique in interventional nephrostomy procedures.
