Abstract
There is controversy regarding the ideal surgical management of intra-abdominal testes (IAT) to preserve fertility; we conducted a systematic review to address this problem. We performed a comprehensive electronic search of CENTRAL, MEDLINE, EMBASE, and CINAHL from 2008 to September 2014 (the date range was limited due to an abundance of literature), as well as reference lists of included studies. Two researchers screened all studies for inclusion, and quality assessed each relevant study using AMSTAR for systematic reviews (SRs), Cochrane 'Risk of bias' tool for randomized controlled trials (RCTs), and MINORS for non-randomized studies. We identified two relevant SRs and 29 non-randomized studies. Due to the heterogeneity of the data, meta-analysis was not possible. Ultrasound and magnetic resonance imaging are insufficient for identification or localization of IAT; laparoscopic or surgical exploration is necessary. Primary orchiopexy is effective for low IAT, and Fowler-Stephens orchiopexy (FSO) is effective for high IAT. There is no clear benefit of one- vs. two-stage FSO, or of open vs. laparoscopic technique. Several alternative or modified techniques also show promise. RCTs are needed to confirm the validity of these findings, and to assess long-term outcomes.
