• Introduction:

  Prostatic urethral lifts (PUL) provide improvement in urinary symptoms for men with benign prostatic hyperplasia (BPH). The aim of this study is to determine operative factors associated with improvement in urinary symptoms after PUL in men with bothersome BPH.

  Materials and methods:

  Men with BPH undergoing PUL at a single, tertiary center were identified from 2019 to 2022. Inclusion criteria included documented prostate volume as well as preoperative and postoperative cystoscopic images of the prostatic urethra. Multivariate regression modeling was performed to determine the predictive factors—including prostate volume, number of implants, and degree of unobstructed prostatic urethral channel—for improvement in International Prostate Symptom Score (IPSS) after PUL.

  Results:

  Of the 47 men, the distribution of prostate volume was 1 patient with < 30 grams, 33 patients with 30-79 grams, five patients with 80-100 grams, and six patients with > 100 grams. The mean number of implants used was six implants. The mean preoperative and postoperative IPSS were 23 and 14, respectively. The mean (standard error (SE)) change and percent change in IPSS score following PUL was 14 and 60%, respectively. The mean percent improvement in prostatic urethral channel after anterior clip placements was 67%. On multivariate analysis, larger prostate volume was associated with greater change in IPPS follow surgery (p = 0.0091) while number of implants and percent of prostatic urethral opening were not associated with change in IPSS (p = 0.3094 and p = 0.2249, respectively).

  Conclusion:

  Men with larger prostates are associated with greater improvement in urinary symptom after PUL regardless of number of implants utilized and degree of prostatic urethral channel opening after prostatic implants.
