“…Ultrasound-guided PCNL without uoroscopy has advantages and disadvantages. Advantages are avoidance of X-ray exposure especially in children 17,20 or pregnant women, no need for lead shielding, possible avoidance of intraabdominal organs in the access path, and possible avoidance of renal vessels using Doppler ultrasound. Nevertheless, it has some disadvantages.…”

Objective to evaluate the non-inferiority of ultrasound puncture followed by non-guided tract dilatation compared to the standard fluoroscopy-guided PCNL. Materials and Methods 40 patients with non-opaque kidney stones eligible for PCNL were randomly divided into two groups. The standard fluoroscopy-guided PCNL using the Amplatz dilator was performed in the XRAY group. In the SONO group, needle puncture was done ultrasound-guided followed by non-guided dilatation using Amplatz dilator based on the tract length. In cases of short-advancement, we used bi-prong forceps under direct endoscopic vision to dilate the parenchyma. The primary outcome was successful access. Results In 90% of cases in the XRAY and 95% in the SONO group access dilatation process was performed uneventfully at the first attempt (p = 0.5). In 45% of cases in the SONO group, bi-prong forceps was used as salvage for short-advancement. In one case in the XRAY group over-advancement occurred. The stone-free rate on CT-scan one month after surgery was 75% for the XRAY group and 85% for the SONO group. (p = 0.4). There were no significant differences in operation time, hospitalization duration, transfusion, or complication rates between the two groups. Conclusion Non-guided tract dilatation after the ultrasound-guided renal puncture in PCNL followed by bi-prong forceps tract dilatation as salvage in case of short-advancement, is not inferior to the standard fluoroscopy-guided PCNL for non-opaque renal stones while eliminating radiation hazard and the risk of over-advancement.

“…Most PCNL procedures are performed under fluoroscopic guidance. However, a previous study demonstrated that ultrasound-guided PCNL reduces cost and radiation exposure and even has the same effect in some special cases, such as pediatric patients with calculi 23 and patients with a retrorenal colon. 24 Only ultrasound has been used in all three dilation procedures in our urology operating room.…”

Objective To evaluate the efficacy and safety of a novel endoscopic dilation (END) method during percutaneous nephrolithotomy under ultrasonographic guidance. Methods We retrospectively reviewed the clinical records of 138 patients who underwent percutaneous nephrolithotomy from June 2020 to December 2021. The patients were divided into three groups based on the method of nephrostomy tract creation: those who underwent fascial Amplatz serial fascial dilation (AMD) (n = 45), one-shot dilation (OSD) (n = 45), and END (n = 48). For END, a 20-Fr dilator with sheath was accessed over the first guidewire. A second guidewire was inserted into the collecting system via the endoscope. The nephroscope was then accessed to enlarge the renal puncture point using both guidewires. Demographic variables and important intraoperative and postoperative findings were compared among the three groups. Results The preoperative characteristics were similar among the three groups. The END group had a significantly shorter access time than both the AMD and OSD groups and significantly less severe hemoglobin loss than the OSD group. There were no significant differences in the other important perioperative findings. Conclusion Use of this novel END method with two guidewires may be associated with less blood loss and a reduced access time.

“…However, as success rates have increased and particular experience has been gained in adults, the technique has also begun to be performed in children as monotherapy, or in combination with other approaches in patients with large stone burdens. Concerns about long-term renal damage, small kidney size, relatively big tools, radiation exposure, and danger of significant problems, such as hemorrhage, contributed to the technique's slow adoption in children [ 48 , 49 ].…”

Fluoroscopy-free ultrasonography-guided percutaneous nephrolithotomy in pediatric patients: a single-center experience

Abstract: The results of this study showed that fluoroscopic-free ultrasound-guided PCNL in pediatric patients of all ages is safe, highly efficient, and minimizes potential radiation exposure risks associated with the procedure.
