Male voiding dysfunction Radiology Urethral stricture Urethroplasty.The urethra's main job in males and females is to pass urine outside the body. The pcRUG is minimally invasive and is comparable in accuracy and sensitivity to voiding cystourethrography and retrograde urethrography that have traditionally been used to assess healing after urethroplasty.
Our pericatheter retrograde urethrogram technique is a safe and reproducible technique to effectively assess urethral healing after urethroplasty and determine timing of catheter removal. There were otherwise no infectious or procedural complications related to pericatheter retrograde urethrogram. One patient (0.8%) presented with urinary leak and scrotal abscess after a urethra was assessed as sufficiently healed at the initial pcRUG and the catheter removed. Patients with extravasation seen on initial pcRUG were more likely to have strictures that were panurethral (36 vs.
Fifteen patients (11.5%) demonstrated extravasation, with 13 of those patients (10%) undergoing a repeat pcRUG. 115 patients (88.5%) had no extravasation on pcRUG. Patient with and without extravasation seen on initial pcRUG were compared.įrom September 2012 through February 2017, 144 pericatheter retrograde urethrograms were performed on 130 patients. The image was then evaluated for the presence of any contrast extravasation. Patients were placed in oblique position, and with the penis stretched, diluted contrast was instilled via an angiocatheter alongside the indwelling urethral catheter under dynamic fluoroscopy. pcRUG was performed at 3-4 weeks after surgery, in standardized fashion. We retrospectively reviewed our prospective IRB-approved database of patients undergoing urethral reconstruction. The purpose of this study is to describe our technique for pericatheter retrograde urethrogram (pcRUG) and to evaluate the utility of a pcRUG to detect a clinically significant leak after urethral reconstruction.
