Young men with defecatory disorders (DDs) often experience lower urinary tract symptoms (LUTS). Bowel-directed physical therapy can improve LUTS, and DDs increase the likelihood of concurrent voiding dysfunction.
Area of Science:
- Urology
- Gastroenterology
- Pelvic Floor Physical Therapy
Background:
- Lower urinary tract symptoms (LUTS) are common in patients with constipation.
- Previous studies on the link between defecatory disorders (DDs) and voiding dysfunction, primarily in women, yielded inconsistent results.
- This study focuses on young men, investigating LUTS prevalence in those with DDs and the association between objectively diagnosed DDs and voiding dysfunction.
Purpose of the Study:
- To determine the prevalence of LUTS in young men diagnosed with DDs.
- To examine the relationship between objectively confirmed DDs and voiding dysfunction in constipated young men presenting with LUTS.
Main Methods:
- Retrospective review of medical records for men aged 18-40 with confirmed DDs treated with pelvic floor physical therapy (PT).
- Analysis of data from a separate group of constipated young men with LUTS who underwent high-resolution anorectal manometry (HRM), rectal balloon expulsion test (BET), and uroflowmetry.
- Utilized validated questionnaires and objective diagnostic tests to assess DDs and voiding dysfunction.
Main Results:
- Of 43 men receiving PT for DDs, 82% reported at least one LUTS, most commonly frequent urination.
- Over half of these men showed improvement in LUTS after bowel-directed PT.
- In 29 constipated men with LUTS, 28% had both defecatory and voiding dysfunction. DDs were significantly associated with increased odds of concurrent voiding dysfunction (OR 9.3).
Conclusions:
- The majority of young men with DDs experience LUTS, which can be alleviated by bowel-directed physical therapy.
- The presence of DDs in patients with urinary symptoms significantly increases the likelihood of coexisting voiding dysfunction.

Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
