Abstract

Abstract:

Objective

To assess the efficacy and safety of ultra-mini PCNL (UMP) in semisupine-lithotomy position.

Methods

During April 2016 to December 2017, UMP for 96 renal stone cases with patients positioned in 45° semisupine-lithotomy position were implemented. The patients were of 60 male and 36 female, aged 25-66 years. The mean stone size was (22±7, 15-41) mm. During operation, a retrograde 9.5/11.5 F ureter access sheath or a 7 F ureteral catheter was firstly placed. The type-B sonography was used for stone locationing and 200 μm holmium laser was used for lithotripsy.

Results

All 96 cases were successfully completed. The mean operative time was (76±33) min. Mean hemoglobin drop was (16±11) g/L. Fever 38.5-38.9℃ occurred in 4 cases. No other complications occurred. The post-operative hospital stay was (3.9±1.3) days. The stone-free rate of 1 month was 91.7% (44/48).

Conclusion

Implementation of UMP in 45° semisupine combined lithotomy position is feasible and safe. The procedure is less invasive and has faster recovery period.
