Renal pelvis rupture during pregnancy: diagnosing a confusing source of despair

We present an impressive case of a pregnant woman presenting with severe right flank pains. A rare rupture of the right renal pelvis turned out to be the cause of her problems. Renal pelvis rupture in pregnancy is difficult to diagnose. It is easily confused with other more prevalent diagnoses, like hydronephrosis, ureteral distension, renal calculus and pyelonephritis. Ultrasonography is not always conclusive. Pyelography seems to be a good diagnostic tool, this case shows that MRI is another option. Renal pelvis rupture can be effectively treated with the insertion of a JJ-stent.
