Two Year Functional Outcomes Stratified According to Baseline Erectile Function Following Partial Gland Cryo-Ablation

To critically evaluate time dependent sexual function following primary partial gland cryo-ablation (PGCA) stratified according to baseline erectile function.

Between March 2017 and March 2022, all men undergoing primary PGCA by 2 surgeons were enrolled in an IRB approved outcomes registry. All subjects with PIRADS 2-5 lesion concordant with unilateral GGG 1-3 disease, no gross extra-prostatic extension on mpMRI, GGG >1 contralateral to the ROI, or distal apical disease on mpMRI were enrolled. Patients completed the Sexual Health Inventory for Men (SHIM) scale at baseline, 6, and 24 months. Men were stratified by baseline erectile function. Men with SHIM Score < 8 were excluded. Ability to sustain erection (aka "potency") was defined as a score of 3 or greater on question 2 of the SHIM index. Median SHIM scores and the proportion of men reporting "potency" at baseline, 6, and 24 months was recorded with comparisons between each timepoint. A univariate analysis was used to determine if clinical factors were associated with loss of "potency" at 24 months.

106 men met the inclusion criteria. There was a statistically significant decrease in the mean SHIM scores for the entire cohort between baseline to 6 months and baseline to 24 months. SHIM scores increased significantly for the total cohort between 6 and 24 months. "Potency" was preserved in 70% at 24 months.

Those patients most likely to exhibit a decrease in sexual function have moderate ED at baseline. Only baseline ED was shown to predict preservation of "potency".
