Primary obstructive megaureter (POM) is uncommon in adults. Urolithiasis formation may uncover the underlying congenital abnormally of these patients.
Herein, we present a 20-year-old man who was admitted with synchronous left renal staghorn and a lower giant ureteral stone. Radiologic evaluations revealed that POM is the underlying cause of the uncommon occurrence of synchronous left reno-ureteral stone formation.
Urinary tract stones are not uncommon in the POM. Although synchronous renal-ureteral unit stones are less common but staghorn-ureteral stones complex are very rare. In such conditions full radiologic work-up is recommended. Based on our literature review, this is the first reported case of staghorn-ureteral stones complex in the setting of adult POM.
In every case with dilated ureter concomitant with ureteral stone or renal stone, the POM should be included in the differential diagnosis.
原发性梗阻性巨输尿管（POM）在成人中并不常见。尿路结石的形成可能会揭示这些患者潜在的先天性异常。
在此，我们报告一名20岁男性，因同时患有左肾鹿角形结石和下段巨大输尿管结石入院。影像学评估显示，POM是左肾输尿管同步结石形成这种罕见情况的潜在原因。
POM患者中尿路结石并不少见。虽然肾输尿管同步结石较少见，但鹿角形输尿管结石复合体非常罕见。在这种情况下，建议进行全面的影像学检查。根据我们的文献综述，这是首例在成人POM背景下报道的鹿角形输尿管结石复合体病例。
在每一例伴有输尿管扩张并伴有输尿管结石或肾结石的病例中，鉴别诊断应考虑POM。
