Fertility after orchidopexied undescended testes (UDT) is impaired. Although fertility parameters are known to be more favorable in unilateral cases than in bilateral cases, the exact contribution of the unilateral orchidopexied UDT to fertility is unknown. We used testicular (18)F-fluoro-2-deoxyglucose ((18)F-FDG)-uptake assessed by positron emission tomography/computed tomography (PET/CT) to investigate the function of the orchidopexied unilateral congenital UDT, compared to its normally descended counterpart.

Methods: From 2003-2010, 24 boys were observed with 26 undescended testes after inguinoscrotal surgery; 12 had previously undergone inguinal hernia repair and 12 orchidopexy. Spontaneous descent was awaited and (re-)orchidopexy would only be performed in case of non-descent at puberty.
Purpose: The aim of the study was to determine long-term testicular position and growth of acquired undescended testis (UDT) after prepubertal orchidopexy.
Methods: Patients who had undergone prepubertal orchidopexy for acquired UDT at our hospital between 1986 and 1999 were recruited to assess long-term testicular position and volume. Testis position was assessed by physical examination.
Purpose: Perioperative surgical findings in congenital and acquired undescended testis (UDT) were prospectively assessed.
Methods: We included all boys with congenital or acquired UDT who underwent orchidopexy at our hospital between January 2006 and August 2009. Perioperatively, we scored the position and volume of the testis, the insertion of the gubernaculum, the patency of the processus vaginalis, and the obtained position.
