Abstract
Introduction and objectives: To evaluate the possible effects of two different renal puncture techniques (ultrasound-assisted [US-assisted], fluoroscopic-guided [FG]) on the intraoperative hemorrhage risk during percutaneous nephrolithotomy (PCNL). Material and methods: A total of 130 patients with Guy stone scores of 1-2 were prospectively allocated to US-assisted and FG puncture groups by simple randomization. Patients with intraoperative pelvicalyceal rupture and the ones requiring multiple accesses were excluded from the study. Apart from the puncture steps, all other steps of the PCNL procedure were performed with similar techniques by a single surgeon. Patient characteristics, operative data, and postoperative outcomes were compared. Results: A total of 10 patients were excluded from the study due to intraoperative complications after puncture. Patient demographics and stone characteristics were similar between the two groups (P > .05). Mean hemoglobin drop was meaningfully greater in the FG group (1.7 g/dL) when compared with US-assisted group (1.3 g/dL) (P < .01). The mean duration of radiation exposure was significantly higher for the FG (P < .001). Total operative time, number of attempts for a successful puncture, length of hospital stay, and stone free rates were similar between the groups (P > .05). In addition, the remaining complications classified according to the modified Clavien-Dindo grading system were similar between groups (P > .05). Conclusion: US-assisted puncture provides significantly decreased level of hemoglobin drop and radiation exposure time when compared with FG. © 2021 AEU
