The use of scrotal ultrasound in the evaluation of varicoceles: A survey study of reproductive specialists.

ABSTRACT:

Introduction

Urologists use ultrasound in the male infertility workup to evaluate scrotal contents and objectively identify varicoceles if their presence is questionable on physical examination. We assessed practice patterns and diagnostic criteria of male reproductive urologists using ultrasound to evaluate varicoceles.

Methods

An anonymous online survey was sent to the Society for Male Reproduction and Urology (SMRU) members. We queried respondents about ultrasonographic criteria and ultrasound techniques employed in varicocele evaluation. Chi-squared was used to determine association between categorical variables.

Results

In total, 110/320 (34.4%) SMRU members responded. Sixty percent of respondents (66/110) reported performing scrotal ultrasound; 92.4 % (61/66) were attending urologists and 87.9% (58/66) completed an andrology fellowship. A total of 37.9% (25/66) performed their own ultrasound, while the remainder had ultrasound performed by an alternate practitioner. Among those performing their own ultrasound, 95.5% (21/22) measured varicocele venous diameter compared to 76% (29/38) when another practitioner performed the ultrasound. Venous diameter used to define a varicocele ranged from 2-4 mm. Although 80% (49/61) of respondents assessed retrograde flow during ultrasound, only 52.5% reported that retrograde flow was required for varicocele diagnosis. Almost all (60/61) indicated they would fix palpable varicoceles in patients with abnormal semen parameters. Fewer (42.6%, 26/61) respondents stated they would repair varicoceles found exclusively on ultrasound.

Conclusions

Ultrasound is commonly employed by male reproductive urologists to diagnose varicoceles. We identified that practitioners use various ultrasonographic criteria and techniques for varicocele diagnosis. Study limitations include recall bias and high degree of specialization among respondents.

Project description:ObjectiveTo evaluate the compliance of infertile men with the use of scrotal cooling devices. As a secondary objective, sperm parameters, deoxyribonucleic acid fragmentation, and hormone profiles were examined.DesignThis exploratory study on scrotal cooling provided scrotal cooling devices to men with primary infertility and abnormal semen parameters. Feedback on the devices after their use was gathered in the form of a questionnaire, and semen parameters were examined after device use.SettingSingle center infertility clinic in Toronto, Ontario, Canada.PatientsPatients with primary infertility and abnormal semen parameters were prospectively evaluated before and after scrotal cooling.InterventionsOne of two scrotal cooling devices (Underdog or Snowballs) was used, on the basis of patient preference.Main outcome measuresQuestionnaires were completed by patients on compliance with device use and concerns about and recommendations for improving the cooling devices. Baseline deoxyribonucleic acid fragmentation index, sperm parameters, and hormones were measured at the initial visit (t = 0) and at subsequent visits (t = 4-12 weeks). Statistical comparison of values before and after scrotal cooling was performed.ResultsForty patients were enrolled in the study, and the questionnaire was completed by 65.0% (n = 26). Most respondents (76.9%) used scrotal cooling less than the recommended duration. Respondents believed that the devices were uncomfortable (31.5%), impeded work (21.0%), and lost cooling rapidly (14.3%). Significant increases in sperm motility and vitality (from 25.4 % to 29.0% and from 64.8% to 71.7%, respectively) were demonstrated after scrotal cooling.ConclusionsMost patients were not compliant with the recommended use of the scrotal cooling devices because of issues of comfort, convenience, and concealability. Further work on improving scrotal cooling devices is necessary to enhance their potential as a therapeutic tool for men with abnormal sperm parameters and infertility.

Project description:The purpose of this study was to curate clustered findings of duplex ultrasound in the evaluation of spermatic venous varicoceles, and deliver more responses to the present concerns. Archives of 979 men who had undergone scrotum and spermatic venous plexus duplex ultrasound were reviewed. In the duplex ultrasound interrogation, the sizes of the larger vessels of the spermatic venous plexus, peritesticular vessels, and testicular volume and relevant parameters were measured. Findings of the vessels were analyzed. One hundred and eight-one out of 979 patients had varicoceles. Color Doppler flow signal was rendered in veins of pampiniform plexus but not in peritesticular vessels in 501 out of 979 patients; 101 out of 501 patients had veins of pampiniform plexus ≤ 3 mm, no color Doppler flow signal could be rendered in the veins in the 101 patients at supine and standing positions without Valsalva maneuver, color Doppler flow signal could be rendered in the veins in 82 out of 101 patients at supine and standing positions with Valsalva maneuver; no color Doppler flow signal could be rendered in the veins from 19 out of 101 patients with and without Valsalva maneuver at supine and standing positions. 37 out of 979 patients with 61 ipsilateral testicular volume ≤ 5 mL had no vessel diameter > 2 mm. The incidences of varicoceles corresponding to different ranges of testicular volume of 1-5 mL, 5.1-10 mL, 10.1-15 mL, 15.1-20 mL, 20.1-25 mL, and 25.1-30 mL were 0.0%, 6.9%, 8.3%, 6.63%, 20.94%, and 59.1%, respectively. The comparisons of incidences of varicocele between distribution percentages of different ranges of testicular volume of 1-5 mL and others (of 5.1 mL and more) were all significant (all P < 0.05). The correlation coefficient between the different ranges of testicular volume and the incidence of varicoceles was 0.829. Increased testicular volume may be also a factor for the development of varicoceles. Dilated peritesticular vessels may be collateral veins of spermatic veins, anterior and posterior scrotal veins, or proximal vas deferens.
