[An analysis of 103 patients with renal injuries]

Between 1971 and 1983, 103 patients with renal injury were admitted to the Department of Urology, Tatebayashi Kosei Hospital. There were 87 males and 16 females. The most frequent age group seen (27.2% of patients) was the 10 to 19 year group. The various causes included traffic accidents (55 patients), falls (16 patients), athletic injuries (8 patients), labor accidents (7 patients), blows (6 patients) and others (11 patients). Associated injuries were present in 52.4% of the patients, including thoracic injuries such as rib fracture (20 patients), lumbar vertebra and transverse process fractures (18 patients), and head injuries (12 patients). Evaluation of the renal injuries was made by excretory urogram (IVP) and conservative management was for most, contusion and rupture, and operation for laceration as a principle: 95 patients (97 renal injuries) were treated by conservative management and 7 patients were treated surgically, 5 patients by nephrectomy and 2 patients by perirenal drainage. Nine patients who had associated injuries were treated surgically. In the follow-up study of 41 patients who had received conservative management and operation (perirenal drainage), followed for more than 6 months and had IVP, urinalysis and blood pressure measurement, representative changes were calyceal deformity (3 patients), renal calculus formation (2 patients) and non-functioning kidney (2 patients) in urograms.
