Purpose: To investigate the clinical efficacy and safety of ultrasound-guided percutaneous nephrolithotomy(PCNL) assisted by a puncture frame.
Materials and Methods: Clinical data of 106 patients with kidney stones who underwent ultrasound-guided percutaneous nephrolithotomy from October 2016 to December 2017 in our hospital were analyzed retrospectively. The channels were established by the assistance of the puncture frame.
Results: The average puncture time was (35±18)s, the puncture was performed for (1.3±0.9) times on average. The puncture was successfully performed at one time in 73 cases. The operation time was (67.3±39.2)min, and the intraoperative blood loss was (48±22) ml. The stones were located on the left in 50 cases, and on the right in 56 cases, The channels were established through the upper, middle and lower calyces of the kidney in 78, 20, and 8 cases, respectively. The puncture sites were located on the upper and lower 12th rib in 81 v.s 25 cases. Intraoperative and postoperative blood transfusion was given in 4 cases, pleural injuries occurred in 2 patients, and hydropneumothorax occurred in one case and closed thoracic drainage was performed. The stone free rate after a single surgery was 87.7% (93/106).
Conclusion: Establishing a percutaneous nephroscope channel under ultrasound-guided assisted by the puncture frame is an efficacious and safe approach.
