Traumatic rupture of the urinary tract in a patient presenting nephrogenic diabetes insipidus associated with hydronephrosis and chronic renal failure: case report and review of the literature.

We report the case of a 34-year-old Japanese man suffering from a nephrogenic diabetes insipidus (NDI) associated with bilateral hydronephrosis, hydroureters and enlarged trabeculated bladder without obstruction. He also presented with chronic renal failure which has rarely occurred in similar cases. The patient was admitted after a traumatic rupture of the left urinary tract which had never been described until now in NDI. He was treated successfully by transient peritoneal and vesical drainages. This paper focuses on the very rare complication of chronic renal failure secondary to hydronephrosis in cases of NDI. The literature of this association is reviewed.
