Simultaneous bilateral percutaneous nephrolithotomy / 中华泌尿外科杂志

ABSTRACT

Objective To discuss the safety and efficacy of simultaneous bilateral percutaneous nephrolithotomy (SBPCNL) for bilateral renal or upper ureteral calculi. Methods Forty-eight cases (26 males, 22 females, 24-57 years )who underwent SBPCNL with pneumatic and ultrasonic power for bilateral renal or upper ureteral calculi were retrospectively reviewed. Clinical data including opera-tion time, blood loss, transfusion rates, length of hospital stay, stone free rate and complications were analyzed. Results The percutaneous renal access was successfully established under ultrasonic guid-ance in all patients. The average operation time was(105±18) rain(range 80-190 min). The average drop in hemoglobin was 21 g/L (range 5-54 g/L), with 5 patients requiring blood transfusion. In 43 patients, a single stage was performed on both sides, while 5 required the second stage PCNL on one side. A single tract was adopted on both sides in 44 patients, while 4 cases of the patients required two tracts on one side. No one required two tracts on both sides or more than one stage on both sides. The stone-clearance rate was 87.5 %. The average hospital stay was 6.5 d. There was no severe complica-tion occurred. Conclusion SBPCNL might be safe and effective for bilateral renal or upper ureteral calculi for selected patients.
