Objective:
To investigate the run and distribution of penile deep veins and to evaluate the application of the findings to penile vein ligating operation.
Methods:
We dissected the penises of 28 formalin-preserved male adult cadavers, whose health condition, penile erection condition when alive, exact age and cause of death were unknown, and recorded the number and location of the cavernous and crural veins and their relationship with the surrounding important organs and tissues.
Results:
The cavernous veins emerged from the dorsal groove of the fixed segment, ran proximately in the dorsal groove, branched into two and drained into either side of the internal pudendal vein respectively, with the internal pudendal artery-cavernous artery-dorsal artery system running laterally and superficially. All the cavernous veins had communications with the periprostatic venous plexus. In the 56 crura of the 28 specimens, there were 250 crural veins, 76 in 42 sides (75.0%) traveling medial to the internal pudendal artery-cavernous artery-dorsal artery system.
Conclusion:
The penile deep venous system is structurally complicated, extensively connected with the surrounding veins and closely related to the surrounding organs, which makes it very difficult to ligate all the deep veins and avoid damage to the cavernous arteries and nerves in vein-involved surgery.

Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
