As subpubic masses are rare, there is no standard treatment.

After establishing general anaesthesia, the penis and subpubic region are prepared with 0.5% chlorhexidine in 70% alcohol (Pharmacia (Perth) Pty Ltd) and the ultrasound probe covered with a 10X14 cm IV3000 Standard[TM] (Smith & Nephew Hull, U.K.).
The subpubic space when viewed in the mid-line sagittal plane is a triangle defined inferiorly by deep penile fascia (Buck's) encasing the penile neurovascular bundle and the corpora cavernosa, superiorly by the pubic symphysis and anteriorly by the membranous layer of the superficial fascia (Scarpa's).
Ultrasound allows the three-dimensional anatomy of the subpubic space and penile structures to be clearly defined.
