[Closed renal trauma: 287 cases. Evaluation of treatment and long-term follow-up]

We evaluated 287 cases of blunt renal trauma that had been treated at the Urology Department of the Valle de Hebrón Hospital from 1974 to 1987. Data gleaned from patient work up, diagnosis and treatment during the acute phase are presented, highlighting the early and long-term results. Patient follow-up ranging from 1 to 10 years and data from statistical analyses show that conservative treatment achieved better early and late results than surgical treatment of the compromised renal unit. Hypertension was an uncommon secuela in our series (1% incidence). Evaluation with radioisotopes has proved to be the most reliable diagnostic method in the long-term assessment of secuelae in the renal unit.
