“…TM has been associated with testicular germ cell tumour and with precursor carcinoma in situ (Husmann, 2005). The prevalence of TM in asymptomatic boys and young men is racially dependent and reportedly ranges from 2.4 to 5.6% (Hobarth et al, 1992;Bach et al, 2001;Peterson et al, 2001;Serter et al, 2006;Goede et al, 2009). Undescended testis (UDT) may be manifested at birth as congenital cryptorchidism or later in childhood as acquired UDT.…”

SUMMARYThe aim of this study was to observe the prevalence of testicular microlithiasis (TM) in surgically corrected acquired undescended testis (UDT). The prevalence of TM was assessed by ultrasound. Boys and young men who had undergone orchidopexy (ORP) for acquired UDT in mid or late childhood were observed to study the long-term testicular volume. During this examination, the presence or absence of TM was also assessed. TM was defined as echogenic foci without shadowing within the testis parenchyma. We included 106 patients who had undergone ORP at the Medical Center Alkmaar (1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999) and 155 patients who had undergone ORP at the Juliana Children's Hospital (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009). The majority of patients were white, Caucasian (82%). The median age at followup, 25.8 years (range 14.0-31.6 years) was higher in Medical Center Alkmaar than in Juliana Children's Hospital 13.4 years (range 5.1-26.6 years). From 2009 to 2011, these 261 patients (median age 18.9 years) underwent an ultrasound examination. Median follow-up after ORP was 11.3 years (range 1.4-23.5 years); age at ORP ranged from 2.1 to 16.2 years, with a median of 8.5 years. TM was found in 17 (6.5%) patients (median age at follow-up 20.4 years; range 11-28). No significant association was found with the incidence of TM and the operated testis, the age at ORP or the racial variance (p > 0.05). ORP at diagnosis for acquired UDT is associated with a 6.5% prevalence of TM in boys and young adults.

“…Testicular microlithiasis is a relatively uncommon finding in the general population, occurring in approximately 0.6% of patients (43). Historically, testicular microlithiasis was initially thought to be an innocuous incidental finding.…”

“…The distribution of the calcifications can be diffuse or focal, and the TM can be unilateral or bilateral. The most common form of presentation is tiny specks of echogenic foci distributed diffusely, bilaterally, and symmetrically within the testicular parenchyma 1,7 . This pattern of presentation was found in our study.…”

“…The typical presentation of TM is diffuse calcification (consisting of hydroxyapatite crystals surrounded by layers of collagen fibers) in the seminiferous tubules. There is evidence that TM is a precursor of testicular germ cell tumors 1,2 and that it is associated with infertility 3 . However, it remains unknown whether these are true cause-and-effect relationships or just incidental findings.…”

Brazil. Conception, design and responsible for the surgical procedures. lll MD, Graduate Student, UFTM, Uberaba-MG, Brazil. Involved in the design, collect of data and helped to draft the manuscript. ABsTRACTPuRPOsE: To evaluate the prevalence of testicular microlithiasis among pediatric patients with inguinoscrotal affections. METHOds:Between January 2005 and January 2010, we evaluated, prospectively 1504 children ranging from 1 to 15 years with inguinoscrotal affections with a high-frequency ultrasound system, which employs a 10-MHz transducer. REsuLTs: Testicular microlithiasis was identified in 20 testes of eleven children (0.71% of 1504 patients evaluated), through an ultrasound scan. Testicular microlithiasis was found in 5 children with cryptorchidism (3.93% of 127 patients), 4 children with retractile testes (14.8% of 27 patients), 1 child with a hypotrophic testis (100% of 1 patient), and 1 child with inguinal hernia (0.07% of 1349 patients). The children with testicular microlithiasis were submitted to annual physical examinations and ultrasound evaluations.CONCLusIONs: Testicular microlithiasis was a rare condition and occurred in 0.7% of the subjects studied. The association with cryptorchidism, retractile and hypotrophic testis was significant.
