Deflating penile prosthesis drain: detach, photograph contents (WhatsApp for serum monitoring 30-40 ml/day), empty into toilet, compress pump to restart suction, close with blue cap; pump must stay compressed (suction active). Outpatient removal after 3-5 days (depends on vascularization/age); block pump during withdrawal to prevent backflow .

Penile prosthesis drainage post-operatively: patient discharged with erect penis and scrotal drain emptied every 12 hours (8am/pm), sending WhatsApp photos for monitoring. Erection promotes hemostasis (no cavernosal bleeding), drainage prevents scrotal swelling from minimal serum/blood; empty into toilet by compressing bulb to restart suction .
