[Acute urine retention due to herlyn-Werner-Wunderlinch syndrome.].

Herlyn-Werner-Wunderlich syndrome (HWW) is a rare congenital anomaly difficult to diagnose due to an alteration in the common embryological development of the reproductive and urinary tract, with renal agenesis, double collecting system, renal duplication and horseshoe kidney as urologic abnormalities. Due to its rarity and associated urological alterations, we believe that the urologist should be aware of this syndrome because of its implications. MATERIAL AND METHODS: We present the case of an 18-year-old patient with acute retention of urine associated with Herlyn-Werner-Wunderlinch syndrome. We describe this syndrome after a bibliographic search. RESULTS: In our case, the initial clinical course was exclusively urological, with the presentation of voiding bladder dysfunction with subsequent acute retention of urine. Surgical treatment resolved the patient's initial complication. CONCLUSIONS: In this case, as in others, nonspecific and variable symptoms may delay the diagnosis, which may lead to late complications such as endometriosis, adhesion syndrome, collections and infertility. Treatment suppresses pain, improves reproductive capacity and prevents late complications.
