Reinforcement for percutaneous nephrostomy tubes with a new technique

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Percutaneous nephrostomy (PCN) is crucial for renal collecting system decompression.
• Percutaneous nephrostomy tubes (PNTs) are prone to mechanical drag and dislodgement despite secure fixation.
• Existing fixation methods may not fully prevent PNT dislodgement.

Purpose of the Study:

• To introduce and evaluate a novel, simple method for reinforcing PNTs against dislodgement.
• To improve the stability and security of nephrostomy tubes after percutaneous procedures.

Main Methods:

• A prospective study involving 133 adult patients undergoing ultrasonography-guided PCN.
• A new fixation technique using a longitudinally sheared rubber drainage tube encasing the PNT was applied to 48 patients.
• The remaining 85 patients received conventional PNT fixation.

Main Results:

• No instances of tube dislodgement were observed in the new method group at 2 and 4 weeks post-procedure.
• Significant reduction in dislodgement rates compared to the conventional group (0 vs 7 at 2 weeks, P=0.049; 0 vs 10 at 4 weeks, P=0.014).

Conclusions:

• The novel rubber drainage tube reinforcement technique is a simple, effective, and inexpensive solution.
• This method significantly decreases the incidence of PNT dislodgement.
• The technique ensures reliable fixation of nephrostomy tubes post-surgery.
