The importance of gray scale and color Doppler ultrasonography in the diagnosis of spontaneous renal pelvis rupture: case report

Peripelvic extravasation associated with spontaneous rupture of renal pelvis is a rare occurrence, caused mostly by the obstruction due to calculus. However, the presence of renal anomalies increases the risk of rupture. Urinary extravasation leads to flank pain and may cause acute abdominal symptoms. Especially, the displacement of viscera by extravasated urine and the presence of gastrointestinal symptoms arising through intestinal reflex stimulation renders diagnosis more difficult. Ultrasonography, intravenous urography and computed tomography are the most efficient diagnostic tools in the diagnosis of pelvic renal rupture. In the present study, pre- and post-treatment radiological imaging findings of a case with renal pelvis rupture due to right ureter stone and the use of gray scale and color Doppler ultrasonography in the diagnosis has been discussed.
