Differential Diagnosis for a 29-year-old Male with Perennial Pain, Constipation, and Intermittent Dysuria

Single Most Likely Diagnosis

  • Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS): This condition is characterized by chronic pain in the pelvic region, often accompanied by urinary symptoms and sexual dysfunction. The presence of pelvic muscle tenderness on digital rectal examination (DRE) and negative urine tests supports this diagnosis, as it suggests the pain is not due to a urinary tract infection or other urological condition.

Other Likely Diagnoses

  • Irritable Bowel Syndrome (IBS): Given the symptoms of constipation and abdominal pain, IBS should be considered. Although it primarily affects bowel habits, it can also cause pelvic discomfort.
  • Pelvic Floor Dysfunction: This condition involves the muscles of the pelvic floor becoming tight and painful, leading to symptoms similar to those described, including constipation and pelvic pain.
  • Interstitial Cystitis: A condition causing bladder pressure, bladder pain, and sometimes pelvic pain, which could explain the intermittent dysuria and pelvic pain.

Do Not Miss Diagnoses

  • Testicular Cancer: Although rare in this age group, testicular cancer can present with a dull ache or pain in the testicles or pelvic area. It's crucial to rule out this condition due to its potential severity and the importance of early detection.
  • Prostate Cancer: Similarly, while less common in younger men, prostate cancer can cause pelvic pain and urinary symptoms. Early detection is key to effective treatment.
  • Spinal Cord Injury or Disease: Conditions affecting the spinal cord, such as multiple sclerosis or a spinal cord injury, can cause a wide range of symptoms including pelvic pain, constipation, and urinary dysfunction.

Rare Diagnoses

  • Pudendal Neuralgia: A condition characterized by pain in the distribution of the pudendal nerve, which could explain the pelvic pain and urinary symptoms.
  • Sacral Nerve Root Compression: Compression of the sacral nerve roots can cause pelvic pain, bowel and bladder dysfunction, and other symptoms matching the patient's presentation.
  • Malacoplakia: A rare inflammatory condition that can affect the urinary tract and cause symptoms similar to those described, although it is more commonly associated with immunocompromised states.
