A Critical Evaluation of the Utility of Imaging After Urethroplasty for Bulbar Urethral Stricture Disease.

OBJECTIVE

To determine the incidence of extravasation on initial postoperative pericatheter retrograde urethrogram (pcRUG) after bulbar urethroplasty and the relationship to repair type.

MATERIALS AND

METHODS

We performed a retrospective review to collect stricture-related and postoperative information with emphasis on pcRUGs. All men had a pcRUG at the initial follow-up appointment. The Foley catheter was removed if no extravasation was seen and left in place for an extra week, with a repeat pcRUG if extravasation was noted.

RESULTS

We limited our analysis to men who underwent bulbar urethroplasty from January 1996 to December 2012 (by two surgeons: GDW, ACP). We identified 437 patients and 407 (93%) had follow up data. The mean stricture length was 1.97 cm ± 1.2 cm. In those patients who underwent excision and primary anastomosis (EPA) (n = 232, 57%), we performed the1st pcRUG 1 week earlier compared to those who underwent augmented anastomotic repair (n = 150, 37%) or onlay repair (n = 25, 6%). There was no difference in extravasation rates among all repair types at first pcRUG. The overall rate of extravasation on the first postoperative pcRUG significantly decreased in all patients (0.98% vs 5%, P = .0008) and in those who underwent EPA (5.6% vs 0.4%, P = .0016) when the Foley catheter remained for an extra week.

CONCLUSION

Men who undergo bulbar urethroplasty have a low extravasation rate (2.2%) 3 weeks postoperatively and those who underwent EPA benefited from an additional week of catheterization.
