Where is the posterior Chapman point for the urethra located?

• A. Superior TP of L2
• B. Between PSIS and SP of L5
• C. Medial pubic ramus near symphysis
• D. Superior pubic ramus near symphysis

Answer: (A)

Chapman points map visceral issues to specific somatic locations, with posterior points lying along the spine at the level of the associated spinal segment. The urethra’s posterior Chapman point is at the superior edge of the transverse process of the second lumbar vertebra. In practice, you palpate the deep paraspinal area just lateral to the L2 spinous process to feel for a tender, nodular point. This location corresponds to the urethra’s visceral representation and is the correct site among common options. The other sites listed are anterior points or relate to different structures, not the urethra’s posterior point.
