Management of hydrocele in adolescent patients

Hydrocele is defined as an abnormal collection of serous fluid in the potential space between the parietal and visceral layers of the tunica vaginalis. In the majority of affected adolescents, hydrocele is acquired and is idiopathic in origin. The pathogenesis of idiopathic hydrocele is thought to be an imbalance in the normal process of fluid production and reabsorption. The diagnosis is usually clinical. Taking a thorough history is essential to rule out any fluctuation in size, which is an indication of a patent processus vaginalis. Scrotal ultrasonography is mandatory in nonpalpable testicles to rule out a subtending testicular solid mass requiring inguinal exploration. Otherwise, open hydrocelectomy via a scrotal incision is the standard treatment of idiopathic hydroceles. The second most common cause of hydrocele in adolescents is varicocelectomy. The risk of hydrocele formation is higher with non-artery-sparing procedures or those performed without microsurgical aid, and in surgery requiring cord dissection. If hydrocele occurs after varicocelectomy, initial management should include observation with or without hydrocele aspiration. Large persistent hydroceles are best served by open hydrocelectomy

Carefully selected intratesticular lesions can be safely managed with serial ultrasonography

OBJECTIVE To evaluate a policy of conservative non-operative management for incidental, impalpable, < 1 cm, intratesticular pathology. PATIENTS AND METHODS We retrospectively reviewed all scrotal ultrasonograms within an 8-year period to identify all radiological lesions of < 1 cm within the testis. All palpable lesions and those accompanied by elevated tumour markers or disseminated malignancy were managed surgically. The remaining incidentally detected lesions were followed with a protocol of serial ultrasonography (US). RESULTS Of 1544 scans reviewed, 12 (0.8%) lesions suitable for observational management were identified. The mean (range) age of the patients was 54 (34-76) years. The indication for US was suspected epididymitis in five, contralateral epididymal cyst in five and infertility in two patients. The mean (range) size of the lesion was 4.9 (1.5-9.8) mm. Three anechoic lesions were consistent with intratesticular cysts, and each was followed with no change to a mean (range) follow-up of 26 (12-48) months. Eight hypoechoic lesions were followed to a mean of 34 (4-72) months, and only one showed growth on repeat US after an interval of 4 months, and was diagnosed as a 1.0-cm seminoma after orchidectomy. One hyperechoic lesion remains unchanged at 6 months of follow-up. CONCLUSION Supported by previous reports suggesting that most testis lesions of < 1 cm are benign, we managed a series of carefully selected intratesticular lesions conservatively, the behaviour in most being in keeping with benign pathology

Contrast-Enhanced Ultrasound in the Evaluation of Focal Testicular Complications Secondary to Epididymitis

OBJECTIVE. The purpose of this study is to determine the effectiveness of contrast-enhanced ultrasound in evaluating incidental focal testicular lesions in epididymitis. MATERIALS AND METHODS. Intratesticular lesions ipsilateral to epididymitis were subject to B-mode color Doppler ultrasound and contrast-enhanced ultrasound, with their appearances reviewed in consensus. Final interpretation was by histologic analysis or follow-up ultrasound. RESULTS. Over 28 months, 16 focal testicular lesions (median lesion size, 24 mm; range, 14-48 mm) in 14 patients (median age, 49 years; range, 18-81 years) were examined. Lesions were oval (n = 14), wedge shaped (n = 1), or involved the entire testis (n = 1). Lesions were isoechoic (n = 1), hypoechoic (n = 4), or of mixed echogenicity (n = 11). Color Doppler ultrasound flow was not clearly depicted in 13 lesions but was present in three lesions, with contrast-enhanced ultrasound concordant with color Doppler ultrasound, showing unequivocal absence of vascularity and increased flow, respectively. In the avascular lesions, rim enhancement (n = 6), vascular projections (n = 4), and irregular (n = 10) and smooth (n = 2) borders were documented. The observers identified infarction (n = 9), abscess (n = 4), orchitis (n = 1), and tumor (n = 2). Histologic examination (seven lesions in five patients) confirmed infarction, abscess formation, and seminoma; follow-up ultrasound confirmed resolution for eight patients. CONCLUSION. Contrast-enhanced ultrasound is a useful adjuvant to color Doppler ultrasound examination of a focal lesion in the testis ipsilateral to epididymitis to improve the characterization of nonvascularized tissue.</p
