Long-time follow-up of patients with conservatively treated blunt renal injuries.

A long-time follow-up of 43 patients with minor or intermediate degree blunt renal injuries is presented. A low incidence of complications, including hypertonia, calculi, and infections, was noted, but in three patients, the function of the injured kidney was affected, and two of these also had structural abnormalities as demonstrated by urography. It is recommended that the follow-up of patients with blunt renal injuries should include both urography and renography.
