D J B Keene, R M Cervellione
INTRODUCTION: In the 1970s, Tauber described the antegrade sclerotherapy technique to treat varicoceles, and reported a 10% recurrence rate. The present study aimed to evaluate paediatric success rates and the effect of modifications to the surgical technique. METHODS: A prospective study was performed of all adolescent patients undergoing antegrade sclerotherapy surgery. Each patient had an idiopathic varicocele with spontaneous venous reflux on Doppler examination, and underwent cannulation of a pampiniform plexus vein via a scrotal incision under general anaesthetic...

The objective of this study was to examine testicular ultrasonographic characteristics and endocrine profiles in prepubescent ram lambs for correlations with the age at first detection of elongated spermatids (ESt age). Bi-weekly ultrasound examinations and weekly testicular biopsies began at 10 weeks of age or at the time that testicular volume reached 15cm(3), and continued until 1-2 weeks after Est's were first detected by histological examination of testicular biopsies in twenty-two spring-born Rideau Arcott×Polled Dorset lambs...

We describe a case of a man aged 57 years admitted to our tertiary centre via his general practitioner, presenting with a 1-week history of scrotal pain, testicular swelling and fluctuance. He was initially managed in the community with flucoclaxacillin for 1 week, but failed to respond to treatment. Clinical history was suggestive of Fournier's gangrene, but initial examination was not conclusive. Repeated examination over the next hour aided diagnosis and helped to track the progression of the condition...

Patients with very low sperm count through direct sperm examination can exhibit extreme oligozoospermia or cryptozoospermia (after centrifugation). The management of these patients is a real challenge for both clinicians and biologists. In this retrospective and comparative cohort study, we compared the andrological phenotype of patients with extreme alterations of spermatogenesis and assessed whether the origin of spermatozoa (testicular or ejaculate) had any influence on intracytoplasmic sperm injection (ICSI) outcomes...

AIM: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters. PATIENTS AND METHODS: Scrotal color Doppler ultrasound (CDUS) measurements were made in 33 patients (age 18-31 years) prior to MSV and 3 and 6 months after MSV. Pain was recorded using a visual analog scale and sperm concentration was determined to analyze the predictive value of the CDUS parameters regarding surgical outcome...

A varicocele is described as pathologically enlarged, tortuous veins of the pampiniform plexus, leading to an increased testicular temperature and adrenal metabolite reflux into the testes. Varicocele can impair spermatogenesis and is considered to be the most common cause of male infertility. Patients may palpate a thickening in the scrotum or complain of dull scrotal or inguinal pain, which increases when standing or during erection. In the case of a sudden onset of varicocele in elderly men, it is necessary to exclude renal tumor and extend diagnostic ultrasound with the assessment of the abdominal cavity...

The association between inflammation of the male reproductive system and oligozoospermia has been frequently reported in the clinical work-up of male infertility. To improve sperm parameters in infertile patients with genital inflammation, many phytochemical and nutraceutical drugs are currently being used. However, their use is still empirical and no conclusive data have been provided about their efficacy. The treatment with steroid anti-inflammatory drugs might be useful in reducing inflammation and improving sperm parameters, thus increasing the fertility outcome...

Perinatal testicular torsion, defined as torsion occurring in the prenatal period or in the first month after birth, accounts for 10% of all cases of testicular torsion in pediatric patients. Most are extravaginal, and intravaginal torsion is rare. Its management is controversial, due to the low viability of the testis and the possibility of bilateral torsion. Ultrasonography is the method of choice to study testicular torsion. Combining B-mode and power Doppler imaging facilitates a fast reliable diagnosis...

BACKGROUND: Early postnatal administration of gonadotropins to infants with congenital hypogonadotropic hypogonadism (CHH) can mimic minipuberty, thereby increasing penile growth. We assessed the effects of gonadotropin infusion on stretched penile length (SPL) and hormone levels in infants with congenital micropenis. METHODS: Single-center study including 6 males with micropenis in case of isolated CHH (n = 4), panhypopituitarism (n = 1), and partial androgen insensitivity syndrome (PAIS; n = 1)...

In daily clinical practice, intrascrotal lesion are commonly detected, both by clinical examination either by ultrasound scan. While 95% of testicular lesions are malignant, most paratesticular lesions are benign. Among these, intrascrotal lipomas must be take into account in differential diagnosis. When they originate from scrotal wall, they named "primary scrotal lipoma". We describe a case of a primary intrascrotal lipoma diagnosed after surgical excision in a young man presented at our Urological Department complaining a painful left scrotal mass...

OBJECTIVE: We report a case of enucleation of a non-palpable right testicular lesion found incidentally at testicular ultrasonography during investigations in a patient with azoospermia. MATERIALS AND METHODS: In 2011 bilateral hypoechoic nonpalpable testicular lesions (5 mm and 3 mm to the right, 3 mm to the left) were found in a 28 years old patient, during diagnostic investigations for azoospermia. In March 2016, ultrasonography showed that the diameter of the right major nodule had grown to 12 mm, characterized by increased vascularization and increased texture...

INTRODUCTION: The incidence of benign testicular tumors is increasing in particular in small lesion incidentally found at scrotal ultrasonography. Primary aim of this study was to perform radical surgery in malignant tumor. Secondary aim was to verify the efficacy of the diagnostic-therapeutic pathway recently adopted in management of small masses with testis sparing surgery in benign lesions. MATERIALS AND METHODS: In this multicenter study, we reviewed all patients with single testis lesion less than 15 mm at ultrasound as main diameter...

INTRODUCTION: Azoospermia causes about 10% of male infertility and the best therapeutic option is the retrieval of sperm from testis or epididymis. MATERIAL AND METHODS: From Juanary 2008 to June 2016, 92 men (median 36 years; range: 25-54 years) were submitted in 47 cases to TESE (testicular sperm extraction) and in 45 cases to PESA (percutaneous epididymal sperm aspiration) for secretory and obstructive azoospermia, respectively; moreover, all the patients previously underwent color Doppler ultrasound of the testis and transrectal ultrasound of the prostate...

An asymptomatic 26-year-old man received an annual medical check-up, and chest X-ray showed a protrusion of the aortopulmonary window. Chest computed tomography (CT) revealed an anterior mediastinal tumor and cysts with thin wall and septum enhancement. The preoperative diagnosis was cystic thymoma or malignant lymphoma. We performed total resection of the tumor through a median sternotomy. The pathological findings revealed seminoma, positive for c-kit stain, and multilocular thymic cysts. Cysts were lined by normal squamous epithelium and no seminoma cells were located on their surface...

Bull breeding soundness evaluation (BBSE) is commonly undertaken to identify bulls that are potentially unfit for use as breeding sires. Various studies worldwide have found that approximately 20% of the bulls fail their routine prebreeding BBSE and are therefore considered subfertile. Multiple articles describe the use of testicular ultrasound as a noninvasive aid in the identification of specific testicular and epididymal lesions. Two previous studies have hypothesized a correlation between ultrasonographic testicular parenchymal pixel intensity (PI) and semen quality; however to date, no published studies have specifically examined this link...

Primary testicular lymphoma is rare and appears with nonspecific findings on grayscale and color Doppler sonography. We present 8 patients further examined with contrast-enhanced sonography, strain elastography, and histologic analysis after orchiectomy. Seven of 8 patients had a diagnosis of large B-cell lymphoma, and 1 of 8 had a diagnosis of granulocytic sarcoma, with solitary lesions (2 of 8), multiple lesions (3 of 8), or entire testicular involvement (3 of 8). Lesions appeared hypoechoic (7 of 8) or isoechoic (1 of 8), all with increased vascularity on color Doppler sonography and a nonbranching linear pattern of intratumoral vessels (7 of 8)...

Patients with congenital adrenal hyperplasia have a predisposition for developing adrenal rest tumors. In contrast to testicular adrenal rest tumors, ovarian adrenal rest tumors are less common, and only a few cases have been reported in the literature. This report presents three Chinese female congenital adrenal hyperplasia patients (9 to 15 years of age) with small ectopic adrenal cortical nodules that were not detected by imaging but were diagnosed at surgery. All three patients developed virilization with elevation of 17- hydroxyprogesterone, androstenedione, and androgen levels despite receiving maximum adrenal hormone replacement therapy...
