Eight patients had a history of inguinal hernia (3.4%). The risk of malignant degeneration in an undescended testis proved to be 17 times greater than in the normal population. We found no increased risk for patients with a history of inguinal hernia. Nine patients with a history of orchiopexy developed a malignant testicular tumour; inguinal lymph node metastases were found in three of them. We advise the removal of all undescended testicles after puberty. In cases of malignant degeneration of a testis, which have been fixed in the scrotum, or in cases with a history of an operation in the inguinal region, the inguinal lymph nodes have to be treated. For seminoma, irradiation of these nodes is necessary; for non\u2010seminoma tumours, hemiscrotectomy and inguinal lymph node dissection have to be performed.<\/jats:p>","DOI":"10.1002\/jso.2930140107","type":"journal-article","created":{"date-parts":[[2007,2,20]],"date-time":"2007-02-20T05:45:19Z","timestamp":1171950319000},"page":"45-51","source":"Crossref","is-referenced-by-count":21,"title":["The relation between testicular tumours, undescended testes, and inguinal hernias"],"prefix":"10.1002","volume":"14","author":[{"given":"Th.","family":"Wobbes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.
