  • Introduction:

    Given the increasing interest in partial gland cryo-ablation as a treatment modality and the lack of data surrounding urinary and sexual outcomes after the procedure, the goal of this analysis was to assess functional outcomes following partial gland cryo-ablation (PGCA) stratified according to baseline severity of lower urinary tract symptoms (LUTS) and erectile function (EF). A secondary goal was to also determine if there were any clinical factors associated with significant change in LUTS and EF.

    Materials and methods:

    Since 3/2017, all men undergoing primary PGCA were offered enrollment into an IRB-approved prospective outcomes registry. Men were given International Prostate Symptom Score (IPSS) and Sexual Health Inventory for Men (SHIM) surveys prior to and 6 months post treatment. Differences in IPSS and SHIM scores are described, and factors associated with clinically significant change were assessed using univariate and multivariate analysis.


    A total of 100 men completed 6 month follow up. The mean IPSS for the overall cohort decreased 2.1 units (p > 0.05). The mean changes in IPSS for men with baseline mild, moderate, and severe LUTS were 0.9 (p = 0.06), -4.2 (p = 0.001), and -11.1(p = 0.001) units, respectively. The mean changes in the SHIM score for all men were - 5.1 units (p = 0.001). The mean changes in SHIM score for baseline none, mild/mild-to-moderate, moderate-severe ED were -7.6 (p = 0.001), -6.5 (p = 0.001) and -1.1 units (p = 0.27), respectively. No variables of interest were significantly associated with changes in IPSS or SHIM scores.


    Stratifying functional outcomes according to baseline IPSS and SHIM is imperative to assess the true impact of PGCA on functional outcomes.
