Abstract

Fertility preservation is a major goal in treatment of children with cancer. We describe a new technique of testicular transposition (TT) in patients treated with pulse-dose-rate (PDR) brachytherapy as part of the multimodal conservative treatment of bladder neck and/or prostate rhabdomyosarcoma (BP RMS). Medical records of consecutive patients treated between September 2016 and August 2017 were studied. These patients underwent a TT performed during BP RMS surgery by the same suprapubic incision. The external oblique aponeurosis was not incised. The spermatic cord was mobilized up to the external inguinal ring, and the gubernaculum attachments were severed from the scrotum. The testis was then flipped over with care taken to avoid injury of the vessels or the vas, wrapped in a silicone material and sutured under the abdominal skin with a transfixing stitch facing the anterior superior iliac spine. At the end of brachytherapy, the testis was relocated in the scrotum and during the same general anesthesia, plastic tubes and stents were removed. Surgical outcome and dosimetric parameters were examined. Eight patients were identified. Median age was 24 months (range 11-80 months). All had embryonal BP RMS and received chemotherapy...Continue Reading
