Bochdalek-type Diaphragmatic Hernia Leading to High-grade Kidney Obstruction.

A 94-year-old female presented with sharp right flank pain. Imaging demonstrated herniation of the right renal pelvis and proximal ureter into a large diaphragmatic hernia. She underwent ureteral stent placement with resolution of her symptoms. Congenital diaphragmatic hernias can cause a variety of pulmonary, cardiac, and gastrointestinal symptoms. This is 1 of only 3 cases in the literature of unilateral kidney obstruction due to herniation of the renal pelvis and proximal ureter into a Bochdalek-type diaphragmatic hernia. Ureteral stenting is a good option to decompress the kidney. Hernia reduction and primary diaphragm repair remain the definitive treatment.
