[Traumatic rupture of giant hydronephrosis due to ureteral stone: a case report].

A case of rupture of giant hydronephrosis due to blunt trauma is reported. A 49-year-old male was admitted to our hospital complaining of right flank pain and gross hematuria after falling from a roof. Radiological evaluation lead to the diagnosis of marked right hydronephrosis with severe parenchymal thinning secondary to ureteral stone, left staghorn calculus and the rupture of right kidney. Right nephrectomy was performed and the postoperative course was uneventful. Three weeks later, percutaneous nephrolithotomy (PNL) was performed for left staghorn calculus. Other articles concerning giant hydronephrosis discovered following trauma are reviewed.
