The sonographic pattern of diseases presenting with scrotal pain at Mulago hospital, Kampala, Uganda
Abstract
Background: Scrotal pain is a common presentation in the male patient. There is a wide overlap of symptoms and signs making differentiation at clinical diagnosis difficult. Ultrasound has been documented to improve the accuracy of diagnosis of scrotal diseases. This study was aimed at determining the sonographically detectable diseases in patients with scrotal pain, describe their sonographic appearances and to relate the diseases to the sociodemographic and clinical characteristics of the patients presenting at Mulago hospital.
Patients and Methods: This was a Cross sectional descriptive study done at Mulago Hospital, between May 2003 and March 2004. Consecutive patients with scrotal pain referred for ultrasound evaluation and consented were scanned using an ATL HDI 1500 machine model 2000 with a 5-12 MHz linear probe.
Results: Of the seventy-three patients, 19 had acute epididymitis, 19 chronic nonspecific epididymitis, 12 testicular torsion, and 7 tuberculous epididymo-orchitis diagnosed at ultrasound. The entire epididymis was more often involved and there was no significant difference in pattern of involvement in acute and tuberculous epididymitis except that the frequency of calcifications was significantly higher in tuberculous epididymo-orchitis lesions than in those of either acute epididymitis (p=0.0017) or chronic epididymitis (p=0.0017).Testicular torsion was more common in adolescents and young adults. Acute epididymitis was seen in all age-groups and was associated with anomalies of the genitourinary tract at the extremes of age and sexual activity in young adults. Clinical assessment had low accuracy in diagnosis of cause of scrotal pain.
Conclusion: Scrotal ultrasound gave added information in the diagnosis of patients with scrotal pain. This expedites proper patient management and reduces morbidity. Infections and testicular torsion are the commonest cause of scrotal pain at Mulago hospital. Tuberculous epididymo-orchitis is still a problem at Mulago Hospital.
