Ultrasound IPP til at forudsige respons på medicinsk behandling af LUTS/BPH
Rolle af ultralydsestimat af intravesikal prostatafremspring i forudsigelse af respons på medicinsk behandling hos patienter med nedre urinvejssymptomer sekundære til godartet prostatahyperplasi
This prospective cohort study evaluated whether transabdominal ultrasound measurement of intravesical prostatic protrusion predicts symptom severity and response to medical therapy in men aged 50 years or older with lower urinary tract symptoms secondary to benign prostatic hyperplasia. At baseline, participants underwent clinical evaluation, laboratory assessment including prostate-specific antigen, symptom scoring using the International Prostate Symptom Score and quality of life index, uroflowmetry, and transabdominal ultrasonography to measure prostate volume, bladder parameters, post-void residual urine, detrusor wall thickness, and intravesical prostatic protrusion. Participants were grouped by intravesical prostatic protrusion grade (less than 5 millimetres, 5 to 10 millimetres, and greater than 10 millimetres) and were followed for six months with reassessments at three and six months to evaluate response to medical therapy and identify patients who required escalation of treatment or surgical intervention.

IPP Grade I (<5 mm)
Participants with lower urinary tract symptoms secondary to benign prostatic hyperplasia and intravesical prostatic protrusion less than 5 millimetres measured by transabdominal ultrasonography at bladder volume 100-200 millilitres. Participants received medical therapy as prescribed by the treating urologist and were followed for 6 months with assessments at baseline, 3 months, and 6 months including International Prostate Symptom Score/quality of life, uroflowmetry, and ultrasound parameters. |
Transabdominal ultrasonography; TAUS; Ultrasound IPP measurement Intervention Description: Intravesical prostatic protrusion was measured using transabdominal ultrasonography in the midsagittal plane at a bladder volume of approximately 100-200 millilitres. The measurement was defined as the distance (millimetres) from the bladder neck to the tip of the protruding prostatic tissue, and participants were categorized into Grade I (<5 millimetres), Grade II (5-10 millimetres), or Grade III (>10 millimetres). Ultrasound assessment was performed at baseline and during follow-up per protocol. Participants received an alpha-adrenergic blocker as part of standard medical therapy for benign prostatic hyperplasia-related lower urinary tract symptoms. The specific agent, dose, dosing frequency, and duration were prescribed by the treating urologist and recorded throughout follow-up. Participants received a 5-alpha reductase inhibitor as part of standard medical therapy for benign prostatic hyperplasia-related lower urinary tract symptoms. The specific agent, dose, dosing frequency, and duration were prescribed by the treating urologist and recorded throughout follow-up. |

IPP Grade II (5-10 mm)
Participants with lower urinary tract symptoms secondary to benign prostatic hyperplasia and intravesical prostatic protrusion 5 to 10 millimetres measured by transabdominal ultrasonography at bladder volume 100-200 millilitres. Participants received medical therapy as prescribed by the treating urologist and were followed for 6 months with assessments at baseline, 3 months, and 6 months including International Prostate Symptom Score/quality of life, uroflowmetry, and ultrasound parameters. |

Change in International Prostate Symptom Score
Tidsramme: Baseline and 6 months
|
The International Prostate Symptom Score was used to quantify lower urinary tract symptom severity. The outcome was the change in total score between baseline (pre-treatment) and the 6-month follow-up visit. The International Prostate Symptom Score (IPSS) is a seven-item questionnaire assessing lower urinary tract symptom severity. Each item is scored from 0 to 5, giving a total score ranging from 0 to 35, with higher scores indicating more severe symptoms. The outcome was the change in total IPSS from baseline to the 6-month follow-up visit. |

Change in quality of life score
Tidsramme: Baseline and 6 months
|
Change in the quality of life index associated with the Intenational Prostate Symptom Score between baseline and 6 months. The International Prostate Symptom Score quality-of-life (IPSS-QoL) question is a single item scored from 0 to 6, where 0 indicates the best quality of life and 6 indicates the worst quality of life related to urinary symptoms. Higher scores indicate worse quality of life. The outcome was the change in IPSS-QoL score from baseline to the 6-month follow-up visit. |
