Diagnostic Performance of PIC Cystogram vs VCUG in Children

December 31, 2025 updated by: Tarik Emre Sener

Comparison of the Effectiveness of PIC Cystogram and VCUG in the Diagnosis of Vesicoureteral Reflux in Children

The goal of this interventional diagnostic clinical trial is to evaluate and compare the diagnostic effectiveness of PIC cystography and voiding cystourethrography (VCUG) for the detection of vesicoureteral reflux (VUR) in children undergoing endoscopic procedures, including those who previously underwent VCUG for urinary tract infection (UTI) or other indications, as well as children who did not require VCUG.

The main questions it aims to answer are:

Does PIC cystography detect VUR at a rate comparable to VCUG?

How well do PIC cystography and VCUG correlate in identifying low-grade versus high-grade VUR?

Researchers will compare PIC cystography findings with prior VCUG results to determine agreement between the two diagnostic methods and their ability to detect clinically relevant reflux.

Participants will:

Undergo PIC cystography performed during endoscopic surgery

Have contrast instilled near each ureteral orifice under fluoroscopic monitoring

Be evaluated for the presence and grade of vesicoureteral reflux

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: PIC cystography
Diagnostic test: PIC cystography
PIC cystography is performed intraoperatively during endoscopic surgery. A pediatric cystoscope is positioned adjacent to each ureteral orifice, and contrast medium is instilled by gravity from a height of 1 meter under fluoroscopic guidance. The presence and grade of vesicoureteral reflux are recorded for each renal unit. The procedure is carried out in a standardized manner by an investigator blinded to prior VCUG findings

Measure Description
Time Frame
Detection of vesicoureteral reflux (VUR) by PIC cystography compared with VCUG
Time Frame: During endoscopic surgery (single intraoperative assessment)
Detection of vesicoureteral reflux (VUR) by PIC cystography compared with VCUG, assessed as the presence or absence of reflux and categorized as low-grade (Grade 1-3) or high-grade (Grade 4-5) on a renal unit basis.
During endoscopic surgery (single intraoperative assessment)
