Abstract

OBJECTIVES:

To compare our results of preoperative corporal cavernosography and retrograde urethrography in penile fractures with the clinical and intraoperative findings.

METHODS:

From January to October 1996, 7 cases of penile fracture were diagnosed at our inner city trauma center. All cases were associated with sexual activity and patients underwent preoperative retrograde urethrography and corpus cavernosography with immediate surgical intervention.

RESULTS:

We found that 2 patients who presented with blood at the meatus had intact urethras, whereas 2 of the 3 patients who had urethral lacerations did not have a bloody meatus. In 2 cases the urethrogram and cavernosogram revealed lacerations that were not initially detected surgically. However, in another 2 cases, the urethrogram and cavernosogram were falsely negative. Two of the seven corporal fractures were bilateral and five were unilateral.

CONCLUSIONS:

On the basis of this small sample, it appears that preoperative cavernosography and retrograde urethrography may show additional sites of tears in the corpora and urethra because hematoma formation may mask some ruptures. However, the presence or absence of a bloody meatus may not necessarily correlate with the status of the urethra, and the urologist also should be wary of a false-negative imaging study. We suggest that all cases of penile fracture be explored surgically, but preferably by a subcoronal degloving incision that allows careful examination of the urethra and corpora. Results of a larger series may determine if the routine use of these imaging modalities is justified intraoperatively.
