[Clinical aspects of hydatid torsion. Diagnosis and therapy in 104 consecutive patients].

At the department of the urology of the university hospital in Giessen we observed 104 hydatid torsions with acute scrotal pain between 1977 and 1998. The average age of the affected patients showed a peak in boys with 12 years of age. 33.7% of the patients underwent primary conservative treatment and 66.3% were operated primarily. We only recommend conservative treatment after careful clinical evaluation and definitive detection of testicular perfusion. Scrotal ultrasound and color duplex sonography hereby serve as decisive tools.
