    Abdominal straining during urination after transurethral resection of the prostate (TURP) is common, but it does not correlate with obstruction indicators or affect outcomes. Straining may be an age-related habit.

    Area of Science:

    • Urology
    • Surgical Procedures
    • Lower Urinary Tract Symptoms

    Background:

    • Abdominal straining during voiding is a common symptom in patients with lower urinary tract symptoms.
    • Transurethral resection of the prostate (TURP) is a surgical procedure to treat benign prostatic hyperplasia (BPH).
    • The impact of preoperative straining on postoperative outcomes after TURP requires further investigation.

    Purpose of the Study:

    • To evaluate the prevalence and impact of abdominal straining in patients undergoing TURP.
    • To determine the correlation between preoperative straining and urodynamic or symptomatologic indicators of bladder outlet obstruction.
    • To assess the association between straining and patient outcomes 3 and 12 months postoperatively.

    Main Methods:

    • Prospective evaluation of 46 patients undergoing TURP for voiding symptoms.

  • Preoperative assessments included symptom analysis, excretory urography, cystoscopy, and urodynamic studies (uroflowmetry, cystometry, pressure flow).
  • Postoperative follow-up at 3 and 12 months assessed straining and subjective/objective outcomes.

    • Main Results:

    • 72% of patients strained preoperatively; the majority continued to strain postoperatively.
    • No correlation was found between straining and urodynamic or symptomatologic indicators of bladder outlet obstruction.
    • Patients who strained and those who did not reported similar subjective and objective outcomes postoperatively.
    • A positive correlation was identified between straining and patient age.

    Conclusions:

    • Abdominal straining in the context of TURP may be an individual habit rather than a direct indicator of bladder outlet obstruction.
    • The tendency to strain appears to increase with age.
    • Straining does not appear to negatively impact subjective or objective outcomes after TURP.
