About this study

Penile length and erectile function are complex physiological processes influenced by an interplay of neural, vascular, and hormonal factors. The process of penile erection involves the relaxation of smooth muscles in the corpora cavernosa, leading to increased blood flow and penile engorgement.

Erectile dysfunction (ED), a prevalent condition in men, has been associated with numerous risk factors such as age, cardiovascular disease, diabetes, and spinal cord injury.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult male patients aged 21 years or older.
  • Patients scheduled for elective urological surgeries including transurethral resection of the prostate (TURP) or transurethral resection of bladder tumor (TURT).
  • Patients who provided written informed consent for participation in the study.

Exclusion criteria

  • Presence of a history of erectile dysfunction, penile deformities, or any urological conditions that could affect penile size.
  • Undergoing emergency surgeries or procedures that required alternative anesthetic techniques.
  • Known allergies or hypersensitivity to either spinal or general anesthesia.
  • Inability or unwillingness to provide informed consent.

Treatment and study plan

Spinal anesthesia

Procedure

Patients who underwent surgery under spinal anesthesia.

General Anesthesia

Procedure

Patients who underwent surgery under general anesthesia.

Primary outcomes

  1. Penile length

    Time frame: 20 minutes after anesthesia

    Penile length was measured.

Secondary outcomes

  1. Surgeon satisfaction

    Time frame: At the end of the procedure (Up to 2 hours)

    The operating surgeon was asked to rate satisfaction with operative conditions related to penile size and accessibility using a structured 3-point ordinal scale:

    • Unsatisfied - Surgical exposure was insufficient; procedure was significantly hindered.
    • Hardly satisfied - Procedure was completed with difficulty due to altered penile length or engorgement.
    • Satisfied - No intraoperative difficulty attributable to penile size or exposure.
