How small can we go? Percutaneous nephrolithotomy using 6F nephroureteral catheter

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrolithiasis Management

Background:

• Percutaneous nephrolithotomy (PCNL) is a key procedure for kidney stone removal.
• Optimizing postoperative recovery and patient comfort after PCNL is crucial.

Purpose of the Study:

• To evaluate the efficacy of a 6F antegrade nephroureteral catheter (NUC) in the PCNL pathway.
• To assess the impact of the 6F NUC on postoperative recovery metrics.

Main Methods:

• Retrospective review of 99 consecutive PCNL patients (1998-2000).
• Placement of a 6F NUC post-procedure, with removal based on postoperative nephrostogram findings.
• Analysis of postoperative parameters: length of stay, narcotic use, complications, and stent removal time.

Main Results:

• The 6F NUC was associated with an average length of stay of 2.5 days and 1.7 days of narcotic use.
• 82% of NUCs were removed by postoperative day 2.
• Complications included extravasation (11%) and residual stones (9%); prolonged stay correlated with narcotic use, stent duration, and procedure time.

Conclusions:

• The 6F NUC appears to minimize postoperative narcotic requirements and accelerate recovery and discharge.
• Its small size makes it a promising option for PCNL, warranting further investigation in prospective studies.
