Imaging in Reconstructive Urology

Each imaging modality answers a different clinical question. Selecting the right study — and understanding what it cannot tell you — is as important as performing it correctly. The pages below cover indications, technique, interpretation, and pitfalls for each modality used in functional reconstructive urology practice.

• RUG & VCUGRetrograde and voiding urethrography — technique, stricture interpretation, combined study for PFUI, VUR grading, post-urethroplasty surveillance
• CystographyCT and fluoroscopic cystography for bladder trauma, VCUG / RNC / ceVUS for VUR, augmented-bladder perforation, colovesical fistula, follow-up after bladder repair
• MRIPFUI gap measurement, dynamic POP-MRI, urethral diverticulum, VVF, Peyronie's plaque mapping, VI-RADS, MR urography
• UltrasoundSonourethrogram (SUG), spongiofibrosis grading, renal ultrasound, pelvic floor ultrasound, penile duplex
• Penile Doppler Ultrasound & CavernosometryPDUS technique with ICI vasoactive protocols, normal PSV / EDV / RI thresholds, arteriogenic vs venogenic vs mixed ED, Peyronie plaque assessment, ischemic-vs-non-ischemic priapism, penile fracture, and the DICC gold-standard for veno-occlusive dysfunction
• MAG3 & Nuclear ImagingMAG3 renogram, diuretic protocols, split renal function, DMSA cortical scintigraphy, upper tract surveillance
• CT UrogramUpper tract anatomy, urothelial malignancy, pelvic fracture classification, complex fistula mapping, CT-RUG hybrid
