Speculations with regard to etiology of late ascension of testes include the fixation of the testis by a non-occluded processus vaginalis peritonei and growth of the child. We aimed at investigating a pathologic gubernacular insertion in boys with late ascended testis as a possible causative factor pointing at a primary, embryologic etiology of ascended testes. MATERIAL AND METHODS A multicenter prospective study was carried out between 05/2016 and 09/2017 in children with well-documented ascended testes in 4 pediatric urology centers. Children with previous inguinal surgery and those with retractile testes were excluded. All patients were evaluated regarding their gubernacular insertion during orchidopexy. The presence of a patent processus vaginalis and dis- sociation between the epididymis and testis were documented. RESULTS 77 patients were included prospectively. Mean age at surgery was 73.1 months. The previous scrotal position of the testis was documented in 49.4 % by a pediatric urologist and in 50.4 % by a pediatrician. In 3.9 % we found an orthotopic, deep scrotal gubernacular insertion, whereas it was non-orthotopic in 96,1 % (34.2 % groin, 63.2 % high scrotal). 35.1 % had an open processus vaginalis peritonei, 15.6 % had a small, dysplastic appearing testis with testis-epididymis dissociation. CONCLUSIONS Our results point at a causative role of an ectopic gubernacular insertion and therefore an embryo- logic pathogenetic background in patients with well-documented ascending testes. 14:23–14:26 S9-5 (PP) LONG-TERM EFFECTS OF TESTICULAR TORSION ON PATERNITY AND QUALITY OF SEX-LIFE Eija MÄKELÄ and Seppo TASKINEN Helsinki University Hospital, Paediatric Surgery, Helsinki, FINLAND PURPOSE To evaluate the long-term effects of pediatric testicular torsion on male fertility and sexual function.
