Aneyaculación como síntoma inicial atípico en un paciente con fibrosis retroperitoneal idiopática

Retroperitoneal fibrosis is an uncommon disease of unclear cause. It was described for the first time in English literature by Ormond in 1948. It is characterised by chronic non-specific inflammation of the retroperitoneum that can entrap and obstruct retroperitoneal structures, notably the ureters. In some rare instances, it has been coupled with ejaculatory disorders. Histology would appear to be required for accurate diagnosis, but it does not affect the efficiency of diagnostic tests and procedures. Its importance lies in early diagnosis and early treatment to prevent a negative prognosis and further complications. We present the case of a 46-year-old male patient with a diagnosis of idiopathic retroperitoneal fibrosis, whose first symptoms were anejaculation and bilateral hydronephrosis.
