ABSTRACT
PURPOSE:
To describe the clamp method for performing retrograde sonourethrography (RSUG) and contrast-enhanced voiding sonourethrography (CE-VSUG) via the transperineal approach in male adults. MATERIALS ANDMETHODS:
Prospective study of 113 males (14-86 years) with urethral strictures confirmed by urethrography who received sonourethrography via the clamp method between 2011 and 2015. The characteristic parameters of the quantitative variables were calculated and a comparative analysis of the qualitative variables was conducted using the McNemar test.RESULTS:
RSUG was performed successfully in all the cases (n = 113) and detected 49 cases with anterior urethral strictures; the strictures in the proximal bulbar cone in five of them (10.2%) were not visualised on retrograde urethrography (RUG) (p < 0.05). CE-VSUG was performed successfully in 97 cases and observed posterior urethral strictures in 82; the bladder neck strictures in 6 of them (7.3%) were not observed on voiding cystourethrography (VCUG) (p < 0.05). Retrograde bladder filling was achieved in approximately 6 min.CONCLUSION:
The clamp method enables RSUG and CE-VSUG to be performed simply, effectively and painlessly by a single operator. It also allows the evaluation of cases with urethromeatal alterations (stricture, hypospadias and meatotomy). KEY POINTS ⢠The clamp method enables RSUG to be performed simply and painlessly. ⢠The clamp method requires only one operator and allows assessing urethromeatal alterations. ⢠RSUG shows greater capacity for detecting anterior urethral strictures than RUG. ⢠The clamp method achieves retrograde bladder filling in approximately 6 min. ⢠CE-VSUG shows greater capacity for detecting strictures than VCUG.Key words
