    Critical appraisal of conventional semen analysis in the context of varicocele
    (Frontiers Media, 2016) Kruger, Thinus
    Varicocele is present in approximately 15% of men, and, although it is the most commonly diagnosed cause of male infertility, nearly two-thirds of men with varicoceles remain fertile. It was decided to make use of the current evidence obtained from the previous meta-analyses between 2004 and 2015 as well as available articles covering this field, preferably randomized controlled articles dealing with the topic of semen analysis before and after repair. Two important meta-analyses were discussed as well as other articles dealing with the topic of semen analysis before and after varicocelectomy. The evidence suggests that all semen parameters improve after varicocele repair. Based on the available evidence, it is clear that there is a benefit in treating men with a palpable varicocele. One can expect that all semen parameters will improve within 3 months after repair.

    A new approach to tubal re-anastomosis in South Africa
    (Health & Medical Publishing Group, 2011-05) La Grange, Jane; Kruger, Thinus; Van der Merwe, Kobie; Siebert, Igno; Viola, Maria; Matsaseng, Thabo
    Contraception by means of fallopian tube sterilisation is the most common method used worldwide, and it is estimated that on average 138 million women of reproductive age are sterilised globally each year. Several studies have indicated that the incidence of tubal re-anastomosis in previously sterilised women is 1 - 2%.

    Poor return on investment : investigating the barriers that cause low credentialing yields in a resource-limited clinical ultrasound training programme
    (SpringerOpen, 2018-02-21) Lamprecht, Hein; Lemke, Gustav; Van Hoving, Daniel; Kruger, Thinus; Wallis, Lee
    Background: Clinical ultrasound is commonly used in medical practices worldwide due to the multiple benefits the modality offers clinicians. Rigorous credentialing standards are necessary to safeguard patients against operator errors. The purpose of the study was to establish and analyse the barriers that specifically lead to poor credentialing success within a resource-limited clinical ultrasound training programme. Methods: An electronic cross-sectional survey was e-mailed to all trainees who attended the introductory clinical ultrasound courses held in Cape Town since its inception in 2009 to 2013. All trainees were followed until they completed their training programme in 2015. Results: Only one fifth of trainees (n = 43, 19.7%), who entered the Cape Town training programme, credentialed successfully. Ninety (n = 90, 41.3%) trainees responded to the survey. Eighty-six (n = 86) surveys were included for analysis. Time constraints were the highest ranked barrier amongst all trainees. Access barriers (to trainers and ultrasound machines) were the second highest ranked amongst the non-credentialed group. A combination between access and logistical barriers (e.g. difficulty in finding patients with pathology to scan) were the second highest ranked in the credentialed group. Conclusions: Access barriers conspire to burden the Cape Town clinical ultrasound training programme. Novel solutions are necessary to overcome these access barriers to improve future credentialing success.
