From the Research

The most likely urodynamic study (UDS) finding in this 29-year-old healthy man with perineal pain, constipation, intermittent dysuria, and pelvic muscle tenderness on digital rectal examination (DRE) is A. Low peak flow rate. This patient's presentation is consistent with chronic pelvic pain syndrome (CPPS) or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which is characterized by pelvic floor muscle dysfunction and spasm. The pelvic floor muscle spasm can lead to functional bladder outlet obstruction, resulting in a low peak flow rate on urodynamic testing. The normal urinalysis rules out infection as a cause of his symptoms. Patients with pelvic floor dysfunction often demonstrate increased urethral sphincter activity during voiding, which creates resistance to urine flow. This is different from detrusor sphincter dyssynergia, which is typically seen in neurological conditions, as described in 1, 2, 3. The patient does not have symptoms suggesting detrusor overactivity (urgency, frequency), poor compliance (progressive difficulty emptying), or large bladder capacity (infrequent voiding). Treatment typically involves pelvic floor physical therapy, muscle relaxants, and sometimes alpha-blockers to help with voiding symptoms. According to the most recent study 3, detrusor sphincter dyssynergia treatment options are centered around symptomatic management rather than addressing the underlying causative mechanisms, but this patient's presentation does not align with the typical neurological conditions associated with detrusor sphincter dyssynergia. Therefore, the focus should be on managing the patient's symptoms and improving his quality of life, rather than treating a neurological condition. Some key points to consider in the management of this patient's condition include:

  • Pelvic floor physical therapy to help relax the pelvic floor muscles and improve urine flow
  • Muscle relaxants to help reduce muscle spasm and improve bladder emptying
  • Alpha-blockers to help relax the urethral sphincter and improve voiding symptoms
  • Lifestyle modifications, such as dietary changes and stress management, to help reduce symptoms and improve overall health.
