Trial Title: Intraoperative Cone-beam CT for Percutaneous Nephrolithotomy

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Patients \>18 years old~2. Scheduled for percutaneous nephrolithotomy with stone fragmentation (laser/ultrasonic/mechanical)~3. For the prospective intervention arm, willingness to consent to participate in the study~Exclusion Criteria:~1. Patients whose habitus does not allow for the use of the cone beam CT machine~2. Patients whose stones only reside within the mid or distal ureter(s) and thus would not be easily imaged with cone beam CT~3. Patients who have had lithotripsy on their renal unit within the prior 90 days~4. Pregnant patients

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Intervention arm (Type: EXPERIMENTAL): This arm will receive cone beam CT to perform an abdomen-pelvis CT scan immediately following initial percutaneous nephrolithotomy, before the patient emerges from general anesthesia, to allow the surgeon to determine whether additional work is needed or whether the procedure can be concluded without requiring further imaging or future interventions.
- Retrospective arm (Type: NO_INTERVENTION): This arm will contain a retrospective cohort of patients who underwent surgery prior to the enrollment of the intervention arm. These patients received the standard of care, namely helical CT postoperative day one.

Based on this trial design, predict the completion outcome and termination type (if applicable).
