During TURP, surgeon takes care to dissect above the verumontonum to prevent injury to
External Urethral Sphincter
Urethral crest
Prostatic Utricle
Trigone of bladder
Damage to the external sphincter is avoided provided one uses the verumontanum as a guide to the most distal point of the resection. Reference : page1351 Bailey and Love's sho practice of surgery 25th edition
