To investigate the frequency and types of genetic results in different testicular histology of patients with nonobstructive azoospermia (NOA), and correlated with hormones and sperm retrieval (SR), a retrospective study was conducted in 286 Chinese NOA patients who underwent testis biopsy and 100 age-matched fertile men as the control group. Chromosome karyotype analyses were performed by the peripheral blood chromosome G-band detection method. Screening of Y chromosome microdeletions of azoospermia factor (AZF) region was performed by polymerase chain reaction (PCR) amplification of 11 sequence-tagged sites (STS)...

Multiparametric testicular ultrasound and magnetic resonance imaging (MRI) findings were analyzed in a series of 10 infertile asymptomatic men presenting with pathologically confirmed burned-out testicular tumors. Color/power Doppler ultrasound (CDUS), shear wave elastography (SWE), contrast-enhanced ultrasonography (CEUS), and MRI were performed on 10, 5, 6, and 7 patients, respectively. All lesions appeared as a hypoechoic and hypovascular nodular area at CDUS, SWE, CEUS CDUS, and CEUS (if performed). Shear wave elastography showed a stiffer nodular area compared with the surrounding/contralateral tissues (13 versus 2 kPa); MRI revealed a well-delineated nodular area in hypointense signal on T2, a high apparent diffusion coefficient value, and a lack of enhancement...

Bilobed testicle is a very rare congenital malformation with an unknown etiology. Herein, we report an 18-year-old boy presented with a right-bilobed testicle mimicking a testicular tumor. The present case highlights the importance of considering bilobed testicle as a valuable differential diagnosis of testicular mass to prevent unnecessary surgery. Furthermore, the case could provide more information about presentation and management of bilobed testicle.

INTRODUCTION: Shear wave elastography (SWE) and its derivative Supersonic Shear Imaging (SSI) are newer techniques for the determination of tissue elasticity by measuring the velocity of generated shear waves (SWV), which correlates positively with tissue stiffness.The techniques are integrated into many modern ultrasound systems and have been examined in the evaluation of viscoelastic properties of different organ systems. Two-dimensional shear wave elastography (2D SWE) of the testes has been found to be a useful tool in recent studies which included the determination of standard values in healthy volunteers...

Testicular tuberculosis (TB) is a rare form of genitourinary TB. It is usually presented as painful or painless testicular swelling with or without scrotal ulceration or discharging sinus. Infertility may occur. Epididymal involvement is usually seen in testicular TB. In most cases, genital TB is associated with TB involvement of kidneys or lower urinary tract. Ultrasound (USG) and USG-guided fine needle aspiration cytology of testicular swelling confirm the diagnosis. Anti-TB chemotherapy is the mainstay of treatment to ensure the complete resolution of the lesion...

The reproductive potential of male animals is commonly evaluated using a breeding soundness examination incorporating B-mode ultrasound examination of the testes and recently Doppler ultrasound examination of the testicular arteries. These techniques may detect testicular normality or pathology, and while some measured parameters are associated with semen quality at the time of ultrasound examination, few studies have investigated the relationship with future semen quality. We hypothesized that B-mode and Doppler ultrasound measurements would correlate with future semen quality...

Testicular torsion is a urological emergency affecting 3.8 per 100,000 males younger than 18 years. Differential diagnosis of the acutely painful scrotum is crucial for the advance practice nurse to understand. Advanced practice nurses should consider the differential diagnosis of testicular torsion for any patient with testicular pain despite the patient's age, history, or physical examination findings. The standard of care for a patient with testicular pain to rule out testicular torsion is a Doppler ultrasound scan and an emergent urology consult...

BACKGROUND: Extravaginal testicular torsion (ETT), also called prenatal or perinatal, occurs prenatally and is present at birth or appears within the first month of life. It has different etiology than intravaginal torsion, which appears later in life. Testicular torsion must be taken into consideration in differential diagnosis of acute scrotum and should be confirmed or ruled out at first diagnostic step. Ultrasonography is a basic imaging modality, however diagnostic pitfalls are still possible...

Testicular metastases from renal clear cell carcinoma (RCC) are extremely uncommon. To the best of our knowledge, only 32 cases have been reported in the literature. We report a rare case of testicular metastasis from RCC. A 69-year-old patient presented with discomfort and pain in his left testis. He had undergone laparoscopic left radical nephrectomy at another institution. Scrotal ultrasonography revealed a non-palpable lesion at the upper pole of the left testis with hypoechoic aspect, highly suspicious for malignancy...

INTRODUCTION: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. CASE REPORT: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle...

REVIEW
V Patil, S M C Shetty, S Das
Ultrasonography(US) of the scrotum has been demonstrated to be useful in the diagnosis of fluid in the scrotal sac. Grayscale US characterizes the lesions as testicular or extratesticular and, with color Doppler, power Doppler and pulse Doppler, any perfusion can also be assessed. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin...
