Abstract:
To determine the value of ultrasonography for the diagnosis of testicular rapture due to blunt trauma, we reviewed 69 patients of blunt scrotal trauma, which were evaluated by ultrasound before treatment. Thirty patients were managed conservatively, of which 3 cases were explored lately due to persistent pain or mass, and 39 explored immediately. Of the 30 patients treated conservatively the injury was resolved in 27. Surgical exploration of the 42 cases revealed testicular rupture in 29 and simple hematocele in 13. Analysis of the 29 cases with testicular rupture demonstrated that orchiectomy rates were 20% in early exploration and 53% in delayed exploration. in the 27 cases the testicular rupture was correctly diagnosed by ultrasonography, and there were 4 false-positive and 2 false-negative diagnoses of rupture. The specificity and sensitivity for the diagnosis of testicular rupture are 70% and 93%, and the positive and negative predictive values are 87% and 82%, respectively. Ultrasonography used in conjunction with a thorough physical examination is highly sensitive in identifying testicular rupture, and can provide objective information supporting the need for early surgical exploration in patients with blunt scrotal trauma.
