Background/introduction Epididymo-orchitis, a common urological diagnosis in men aged 18–50, has significant sequelae if inadequately treated. Causative organisms in patients under the age of 35 are most commonly sexually transmitted infections. In patients over 35 enteric Gram-negative organisms causing urinary tract infections are more prevalent. Empiric treatment should be commenced as per guidelines until results of investigations are known.

Aim(s)/objectives To evaluate inpatient management of epididymo-orchitis.

Methods Data was retrospectively collected from June to December 2014 for all epididymo-orchitis patients diagnosed clinically. Information was obtained from notes, radiology and pathology databases. A 3 month prospective study is ongoing to improve investigations and antibiotic prescribing.

Results 7 of 26 inpatients diagnosed with epididymo-orchitis were under 35 years of age and 19 over 35. 19 were diagnosed with unilateral epididymo-orchitis and 7 bilateral. 4 patients developed abscesses, and 1 had an orchidectomy. 6 had a first-void urine, 14 a mid-stream urine, and 3 a urethral swab. 9 patients were discharged on doxycycline and ciprofloxacin, 7 with ciprofloxacin monotherapy. Duration of treatment as an outpatient ranged from 7 to 42 days.

Discussion/conclusion Current inpatient management of epididymo-orchitis varies significantly, and a third of patients are being discharged on doxycycline and ciprofloxacin, a combination not recommended in the BASHH guidelines. BASHH recommends cefuroxime +/- gentamicin for management of inpatients over 35 years of age; however in view of the risk of clostridium difficile this may require updating. This and our ongoing prospective study may provide results to help recommend appropriate antibiotics for inpatients with epididymo-orchitis.
