Surgical treatment of acute epididymitis and its underlying diseases

Two hundred and seventy of 1,031 patients (26%) treated for acute epididymitis between 1979 and 1989 underwent surgery for their disease. Eighty percent of these interventions were therapeutic, 20% diagnostic to exclude testicular torsion or tumor. Diagnostic procedures detected underlying diseases that required surgery in 278/1,031 patients (27%). Two hundred and sixteen of these diseases caused lower urinary tract obstruction and were potentially responsible for the acute epididymitis. There were striking differences in type and frequency of the surgery performed depending on the patients' age. Surgery of epididymitis was almost exclusively diagnostic in patients of a young age (exclusion of testicular torsion) and almost always therapeutic in patients of an old age (abscess, prolonged disease). The rate of surgery for underlying diseases was the same for the young (55%) and old (62%) age groups. Obstruction of the lower urinary tract was the predominant cause for surgical treatment of underlying diseases, being mainly due to malformation in the young age group and due to acquired obstructive diseases in the old.
