[Application value of color Doppler ultrasonography in the diagnosis of ruptured tunica albuginea of the corpus cavernosum penis].

OBJECTIVE

To assess the accuracy and value of ultrasonography in the diagnosis of ruptured tunica albuginea (RTA) of the corpus cavernosum penis. Factors affecting prognosis were analyzed.

METHODS

This retrospective study included 57 cases of RTA of the corpus cavernosum penis ultrasonographically diagnosed and surgically treated in Peking University First Hospital from 2013 to 2021. We analyzed the location, size and number of ruptures and the presence or absence of urethral injury, and compared the intraoperative with the ultrasonographic findings.

RESULTS

Of the 57 cases of RTA of the corpus cavernosum penis diagnosed by ultrasonography, 54 (94.7%) were confirmed by surgery. Preoperative ultrasonography indicated 2 cases of bilateral RTA and 6 cases of urethral injury, while surgery revealed 7 cases of bilateral RTA and 13 cases of combined urethral injury. Those with urethral injury developed no urethral stricture or urinary fistula after one-stage urethral repair. And no severe or moderate ED was found in any of the patients during the 12-month follow-up.

CONCLUSION

Ultrasonography has a high accuracy in the diagnosis of ruptured tunica albuginea of the corpus cavernosum penis, and contributes to the determination of the site of surgical incision.
