Primary obstructive megaureter with a giant lower ureteral stone synchronous with ipsilateral staghorn kidney.

INTRODUCTION

Primary obstructive megaureter (POM) is uncommon in adults. Urolithiasis formation may uncover the underlying congenital abnormally of these patients.

PRESENTATION OF CASE

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.

DISCUSSION

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.

CONCLUSION

In every case with dilated ureter concomitant with ureteral stone or renal stone, the POM should be included in the differential diagnosis.
