Lymphatics from the spongy urethra drain into the following lymph nodes:
Show Hint
Spongy urethra and glans follow the same path as the distal penis, into the deep inguinal group.
Updated On: Jun 24, 2026
- Superficial inguinal nodes
- Internal inguinal nodes
- Deep inguinal nodes
- Sacral nodes
Show Solution
The Correct Option is C
Solution and Explanation
Track the drainage region by region. The spongy or penile urethra runs through the corpus spongiosum and ends at the external urethral meatus, so its lymph follows the lymphatics of the distal penis. Those distal penile lymphatics, including those of the glans, converge on the deep inguinal group of nodes. This makes the deep inguinal nodes the principal drainage site for the spongy urethra.
It helps to separate the three urethral segments. The prostatic and membranous urethra sit deep in the pelvis and send lymph to the internal iliac nodes. The spongy urethra lies in the perineum and penis and sends lymph forward to the deep inguinal nodes. Meanwhile the superficial inguinal nodes handle the surface coverings, the penile and scrotal skin, not the urethral tube inside.
Checking the wrong options: superficial inguinal is skin drainage, the so called internal inguinal group is not a recognised station, and sacral nodes serve pelvic viscera such as the rectum. That leaves the deep inguinal nodes as the answer.
