2. Ultrasound Evaluation of Testicular Volume in Patients with Testicular Microlithiasis Full Text available with Trip Pro

Ultrasound Evaluation of Testicular Volume in Patients with Testicular Microlithiasis Ultrasonography is a useful tool to measure testicular volume. According to the European Society of Urogenital Radiology, the combination of testicular atrophy and testicular microlithiasis (TML) is a risk factor for testicular cancer. Testicular atrophy is defined as a volume of less than 12 ml. The aim of this study was to compare testicular volume in patients with TML to patients with normal testicular (...) tissue.From 2013 to 2015 we included a total of 91 adult patients with TML, and 91 adult patients with normal testicular tissue as a control group. All patients underwent scrotal B-mode ultrasound investigation including measurement of width, length and height in both testicles. Testicular volume was calculated using the formula π/6×length×height×width.The median age for patients with TML was 48 years (range: 19-94 years), and 48 years (range: 20-75 years) in patients with normal tissue.

3. High-frequency ultrasonography and contrast-enhanced ultrasound for the evaluation of testicular capillary hemangioma: A case report. Full Text available with Trip Pro

High-frequency ultrasonography and contrast-enhanced ultrasound for the evaluation of testicular capillary hemangioma: A case report. Testicular capillary hemangioma (TCH) is a rare benign tumor of the testis. To the authors' knowledge, there is currently only a few literatures describing the use of contrast-enhanced ultrasound (CEUS) to diagnose TCH. Accurate preoperative diagnosis of benign tumors can avoid orchiectomy. A case of TCH evaluated using high-frequency ultrasound and CEUS (...) is presented.A 21-year-old male presented with a right testicular mass during a routine physical examination, and was admitted to the authors' hospital for definitive diagnosis and treatment.Combined gray-scale, color Doppler ultrasonography, and CEUS did not exclude the possibility that the right testicular lesion may be a benign tumor. Combined with morphological and immunohistochemical staining results, a pathological diagnosis of TCH was considered.The patient underwent right orchiectomy under general

6. Adenomatoid tumor of the testis mimicking malignant testicular cancer on multiparametric ultrasound Full Text available with Trip Pro

Adenomatoid tumor of the testis mimicking malignant testicular cancer on multiparametric ultrasound Adenomatoid tumor is one of the most common histological subtypes of paratesticular cancer arising from the epididymis. In very rare cases, these tumors appear as intratesticular lesions originating in the tunica albuginea, representing a diagnostic challenge.We present a case of a 51-year-old man with a small (0.9 cm) hyperechoic lesion of the left testicle mimicking testicular cancer (...) on multiparametric ultrasound. The lesion was localized in the peripheral zone, confirming vascularization and increased stiffness on contrast-enhanced ultrasound and real-time elastography. Preoperative tumor markers and hormone levels were within normal ranges. Staging computed tomography was negative. Organ-sparing surgery with tumor enucleation and frozen section analysis was performed, confirming testicular adenomatoid tumor.Currently, no typical ultrasound features can definitively distinguish

7. The ultrasonographic "whirlpool sign" in testicular torsion: valuable tool or waste of valuable time? A systematic review and meta-analysis. (Abstract)

The ultrasonographic "whirlpool sign" in testicular torsion: valuable tool or waste of valuable time? A systematic review and meta-analysis. A positive whirlpool sign (WS) is defined as the presence of a spiral-like pattern when the spermatic cord is assessed during ultrasonography (US), using standard, high-resolution ultrasonography (HRUS) and/or color Doppler sonography (CDS), in the presence of testicular torsion. The objective of this review was to assess the validity and accuracy (...) ).Of the studies assessed, a total of 723 participants were included, with a mean of 72.3 (SD 71.9) participants. Of the participants, 226 (31.3%) were diagnosed with testicular torsion (TT). Meta-analysis of the studies that provided sufficient data resulted in a pooled sensitivity and specificity of the WS of 0.73 (95% CI, 0.65-0.79) and 0.99 (95% CI, 0.92-0.99), respectively.

8. Should we rely on Doppler ultrasound for evaluation of testicular solid lesions? (Abstract)

Should we rely on Doppler ultrasound for evaluation of testicular solid lesions? Colour Doppler ultrasound (CDUS) is the main radiologic tool to evaluate scrotal masses and intratesticular-vascularised solid lesions are mostly considered malign lesions. Objective of this trial is determine ratio of benign lesions in patients with hypervascularised solid intratesticular lesions.Patients who underwent radical orchiectomy due to hypervascularised intratesticular solid lesions detected in CDUS (...) were found to be parameters that predict malignancy.Benign incidence of vascular testicular solid lesions detected with scrotal ultrasound with colour Doppler is greater than expected. In patients with smaller, non-palpable lesions without elevated tumor markers, treatment options other than radical orchiectomy such as testicular sparing surgery should be considered.

9. Assessment of the use of contrast enhanced ultrasound in guiding microdissection testicular sperm extraction in nonobstructive azoospermia. Full Text available with Trip Pro

Assessment of the use of contrast enhanced ultrasound in guiding microdissection testicular sperm extraction in nonobstructive azoospermia. The aim of this study is to assess the value of contrast-enhanced ultrasound (CEUS) as a new non-invasive approach to locate the testicular area in which spermatogenesis is most likely to be found in non-obstructive azoospermic testes and to evaluate the accuracy of CEUS as a predictor of successful sperm retrieval.CEUS was performed in 120 nonobstructive (...) azoospermia (NOA) patients. Microdissection testicular sperm extraction (M-TESE) was performed on the best and poorest perfusion areas selected by CEUS and on conventional areas.In the 187 testicles that underwent M-TESE, the sperm retrieval rates (SRRs) in the best perfusion area and poorest perfusion area over the maximal longitudinal section and conventional area were 63.1, 34.7 and 47.1%. According to receiver operating characteristic (ROC) analysis, the arrival times (AT) ≤27 s, time-to-peak

10. Utility of Preoperative Ultrasound for the Evaluation of Testicular Rupture in the Setting of Scrotal Gun Shot Wounds. (Abstract)

Utility of Preoperative Ultrasound for the Evaluation of Testicular Rupture in the Setting of Scrotal Gun Shot Wounds. A scrotal gunshot wound may result in testicular injury, necessitating urgent scrotal exploration and attempted testicular salvage. Scrotal ultrasound is highly sensitive and specific for testicular rupture in the setting of blunt scrotal trauma but it has been poorly studied in the setting of scrotal gunshot wounds. Our objective was to determine the accuracy of scrotal (...) ultrasound to identify testicular rupture following a scrotal gunshot wound.We retrospectively reviewed the records of patients with a scrotal gunshot wound from 2003 to 2014 in whom preoperative ultrasound was done prior to scrotal exploration. A heterogeneous echo pattern of testicular parenchyma with contour loss was considered a positive examination for testicular rupture. Patients underwent scrotal exploration within 24 hours of presentation. The sensitivity and specificity of ultrasound were

11. Pulse wave Doppler ultrasound of testicular arteries and their relationship with semen characteristics in healthy bulls Full Text available with Trip Pro

Pulse wave Doppler ultrasound of testicular arteries and their relationship with semen characteristics in healthy bulls Semen evaluation is used to estimate the testicular function. In bulls, the spermatozoa present in the ejaculate are the result of a process that begun more than 2 mo earlier, bequeathing a delayed depiction of the actual function of the testis. Since testis vascularization might be critical for the gonad function, selected pulse wave Doppler ultrasound parameters were (...) assessed in this study, for instance the peak systolic velocity, the end diastolic velocity and the resistive index of the testicular artery along the spermatic cord, the marginal portion of the testicular artery and the intratesticular branches of the testicular artery both in healthy adult and young bulls.

13. Pulse Doppler ultrasound as a tool for the diagnosis of chronic testicular dysfunction in stallions. Full Text available with Trip Pro

Pulse Doppler ultrasound as a tool for the diagnosis of chronic testicular dysfunction in stallions. Testicular function is particularly susceptible to vascular insult, resulting in a negative impact on sperm production and quality of the ejaculate. A prompt diagnosis of testicular dysfunction enables implementation of appropriate treatment, hence improving fertility forecasts for stallions. The present research aims to: (1) assess if Doppler ultrasonography is a good tool to diagnose stallions (...) fertile stallions from stallions with testicular dysfunction. Spectral Doppler ultrasound is a good predictive tool for sperm quality since correlations were determined among Doppler parameters and markers of sperm quality. Doppler ultrasonography could be a valuable diagnostic tool for use by clinical practitioners for the diagnosis of stallions with testicular dysfunction and could be a viable alternative to invasive procedures traditionally used for diagnosis of sub-fertility disorders.

18. Prevalence and management of incidental small testicular masses discovered on ultrasonographic evaluation of male infertility. (Abstract)

Prevalence and management of incidental small testicular masses discovered on ultrasonographic evaluation of male infertility. We report the safety of surveillance of small testicular masses incidentally discovered during evaluation of male infertility.We retrospectively reviewed a prospectively collected database to identify patients with male infertility found to have incidental small testicular masses (hypoechoic lesions less than 10 mm) on scrotal ultrasound. The men were offered close (...) surveillance with interval imaging and office followup. Patient and imaging characteristics were collected to compare the surveillance and surgical groups with additional comparisons between benign and malignant pathologies to elucidate predictors of underlying malignancy.Of 4,088 men in whom scrotal ultrasound was completed for male infertility evaluation 120 (2.9%) were found to have a subcentimeter testicular mass. Average followup was 1.30 years (range 0.1 to 16.9). A total of 18 men (15%) proceeded
