Adolescent Varicoceles and Infertility

Inter-disciplinary provider development of an online, interactive adolescent varicocele decision aid prototype

BACKGROUND

Decision-making regarding varicocele management can be a complex process for patients and families. However, to date, no studies have presented ways to mitigate the decisional conflict surrounding varicoceles.

OBJECTIVE

To facilitate a discussion among physicians in order to develop a framework of the decision-making process regarding adolescent varicocele management, which will inform the development of the first online, interactive decision aid.

MATERIALS AND METHODS

Semi-structured interviews with pediatric urologists and interventional radiologists were conducted to discuss their rationale for varicocele decision-making. Interviews were audio recorded, transcribed, and coded. Key themes were identified, grouped, and then qualitatively analyzed using thematic analysis. Utilizing the common themes identified and the Ottawa Decision Support Framework, a decision aid prototype was developed and transformed into a user-friendly website: varicoceledecisionaid.com.

RESULTS

Pediatric urologists (n = 10) and interventional radiologists (n = 2) were interviewed. Key themes identified included: (1) definition/epidemiology; (2) observation as an appropriate management choice; (3) reasons to recommend repair; (4) types of repair; (5) reasons to recommend one repair over another; (6) shared decision-making; and (7) appropriate counseling. With this insight, a varicocele decision aid prototype was developed that engages patients and parents in the decision-making process.

DISCUSSION AND CONCLUSIONS

This is the first interactive and easily accessible varicocele decision aid prototype developed by inter-disciplinary physicians for patients. This tool aids in decision-making surrounding varicocele surgery. It can be used before or after consultation to help families understand more about varicoceles and their repair, and why intervention may or may not be offered. It also considers a patient and family's personal values. Future studies will incorporate the patient and family perspective into the decision-making aid as well as implement and test the usability of this decision aid prototype in practice and in the wider urologic community.

Imaging in Male Infertility

Infertility is defined as inability to conceive despite regular unprotected sexual intercourse for greater than 1 year. Conditions involving the male partner accounts for the infertility in approximately 50% of cases. The goals of imaging in male infertility are to detect treatable/ reversible causes, imaging for sperm retrieval from testis or epididymis for assisted reproductive techniques like in vitro fertilization or intracytoplasmic sperm injection and to provide appropriate genetic counselling for prevention of occurrence of disease in future offspring. The purpose of this article is to describe imaging features in various causes of male infertility to acquaint radiologists with various imaging appearances of causes of male infertility to avoid missing these pathologies.

Right-sided scrotal varicocele and its association with malignancy: a multi-institutional study

PURPOSE

To determine the prevalence of isolated right-sided varicocele due to an obstructing malignancy in patients with no other evidence of malignancy.

METHODS

This retrospective, multi-institutional study included a text search for right-sided varicocele in consecutive reports of scrotal ultrasound studies performed between 4/22/1999 and 06/24/2018. Diagnosis was confirmed by a radiologist based on the following criteria: pampiniform plexus vein diameter of ≥ 2 mm, which has augmented flow or increases by ≥ 1 mm on Valsalva. Inclusion criteria for adequate follow-up were (1) abdominopelvic CT or MRI performed within 3 months prior to, or any time after, the ultrasound study; or (2) presence of clinical documentation more than 2 years after the ultrasound date. Exclusion criteria were existing cancer diagnosis in the abdomen or pelvis, epididymo-orchitis, intratesticular or intrascrotal mass, and prior scrotal surgery. Images of available CT or MRI studies were reviewed for presence of any explanation of right-sided varicocele.

RESULTS

210 patients with right-sided varicocele met inclusion and exclusion criteria. 118/210 had abdominopelvic CT or MRI in the assigned timeframe. Of these, no patients had malignancy that could account for right-sided varicoceles. Of the 92/210 patients without CT or MRI but with available clinical follow-up, none had a malignancy that could have caused an isolated right-sided varicocele. There was no underlying malignancy to explain the right-sided varicocele in any of the patients, 0/210, 95% CI [0.0-1.4%].

CONCLUSION

No associated malignancy was found in patients with isolated right-sided varicoceles to support additional imaging for malignancy screening.

Resveratrol improves reproductive parameters of adult rats varicocelized in peripuberty

The aim of this study was to investigate the protective action of resveratrol against the reproductive damage caused by left-sided experimental varicocele. There was a reduction of testicular major axis in the varicocele group when compared with the other groups; the testicular volume was reduced in varicocele group in comparison to the sham–control and resveratrol groups. The frequency of morphologically abnormal sperm was higher in varicocele and varicocele treated with resveratrol groups than in sham–control and resveratrol groups. The frequency of sperm with 100% of mitochondrial activity and normal acrosome integrity were lower in varicocele group than in varicocele treated with resveratrol, sham–control and resveratrol groups. Sperm motility was also reduced in varicocele group than in other groups. The sperm DNA fragmentation was higher in varicocele group than in other groups. Testicular levels of malondialdehyde were higher in varicocele and varicocele treated with resveratrol groups. The varicocele and varicocele treated with resveratrol groups had a significantly higher frequency of TUNEL-positive cells than sham–control and resveratrol groups; however, immunolabeling of the testes from varicocele treated with resveratrol group showed a lower number of apoptotic germ cells in comparison with the left testis of rats of the varicocele group. Reproductive alterations produced by varicocele from peripuberty were reduced by resveratrol in adulthood. Resveratrol should be better investigated as an adjuvant in the treatment of varicocele. Daily administration of resveratrol to rats with varicocele from peripuberty improves sperm quality in the adulthood.
