Comparative Study of Percutaneous Tic Technique Vs Standard Percutaneous Nephrolithotomy

Area of Science:

• Urology
• Nephrology
• Surgical Techniques

Background:

• Percutaneous nephrolithotomy (PCNL) is a common procedure for kidney stone removal.
• The PERC-tic technique offers an alternative approach to standard PCNL.

Purpose of the Study:

• To compare the efficacy and outcomes of the PERC-tic technique versus standard PCNL.
• To evaluate stone-free rates, need for secondary procedures, and hospital readmissions at 90 days.

Main Methods:

• Retrospective cohort study of 126 PCNL cases (63 PERC-tic, 63 standard).
• Comparison of 90-day stone-free rates, secondary procedure rates, and 90-day hospital readmissions using regression models.

Main Results:

• No statistical difference in 90-day stone-free rates between PERC-tic and standard PCNL (P=.08).
• PERC-tic PCNL showed a 6-fold higher likelihood of requiring secondary procedures for residual stones (71% vs 30%, P<.0001).
• No significant difference in 90-day hospital readmission rates between the groups (P=.47).

Conclusions:

• The PERC-tic technique yields similar 90-day stone-free rates to standard PCNL.
• Higher rates of secondary procedures are associated with the PERC-tic technique.
• Findings may inform patient counseling for complex stone disease management.
