Urological symptoms of acute appendicitis in childhood and early adolescence.

We present 15 cases of acute appendicitis in ten boys and five girls (age 3-15 years) with cardinal symptomatology coming from the urogenital tract, who were treated in our departments. All the patients presented with right renal colic, dysuria, frequency and urinary retention. The symptoms were attributed to an ongoing appendix inflammatory process in close proximity to the right distal ureter and urinary bladder. All the patients were successfully operated, and postoperative courses were uneventful. As the present patient group is the largest reported to date, a classification of the pathophysiology in relation to the clinical presentation is proposed.
