Immediate surgical treatment of major renal trauma.

Of the 77 cases of renal trauma treated at Oulu University Central Hospital during the years 1965--1975, 60 injuries were minor and 17 severe. 73 of these injuries were closed and 4 penetrating. The rate of operative treatment in severe renal injuries was 88% minor renal injuries being treated conservatively. Primary exploration was done in 18 of the 77 cases and in all patients with penetrating injuries. Only 7 of the 73 patients with blunt trauma and one of the 4 patients with penetrating injury required nephrectomy, including one patient with renal carcinoma. 6 of the 77 patients died, most as a result of severe associated injuries, giving a mortality of 8%. None of the surviving patients treated for renal trauma suffered from major complications. In 13 of the 18 patients operated upon, renal injury was the main indication for operation. Operation was performed in 5 of the 18 patients after immediate radiological evaluation. The advantages of immediate surgical management in severe renal injuries are early and final treatment, short hospital stay, and low incidence of complications. Qualifications for emergency surgery are access to renal angiography and familiarity with reparative renal procedures.
