Management of Persistent Testicular Swelling After Hydrocelectomy

Diagnostic Evaluation

Perform scrotal ultrasonography with Doppler to rule out surgical complications and exclude testicular pathology that may have been masked by the original hydrocele, as recommended by the American College of Radiology 1
Scrotal ultrasound with Doppler is the primary diagnostic tool to assess testicular blood flow, evaluate for fluid reaccumulation, identify hematoma or abscess, and detect any underlying testicular mass, according to the American College of Radiology 1

Initiate broad-spectrum antibiotics immediately covering both sexually transmitted and enteric organisms if infection/abscess is present, as suggested by the Praxis Medical Insights 3
Surgical drainage is required for abscess formation with debridement of non-viable tissue, as recommended by The Journal of Urology 4
Consider urological consultation for operative management if conservative treatment fails within 3 days, according to the Praxis Medical Insights 3

Immediate urological referral for radical inguinal orchiectomy is necessary if tumor is confirmed, as hydroceles can mask testicular cancer leading to delayed presentation of metastatic disease, according to the National Comprehensive Cancer Network 5, 6
Obtain serum tumor markers (e.g. tumor markers) before any surgical intervention, as recommended by the National Comprehensive Cancer Network 5, 6, 7
Perform staging CT of abdomen/pelvis and chest radiograph if germ cell tumor is suspected, according to the National Comprehensive Cancer Network 6, 8

Reassess within 3 days and again at 1-2 weeks if conservative management is pursued, to ensure resolution, as suggested by the Praxis Medical Insights 3
