[Normative parameters for monitoring of nocturnal penile tumescences: results of own observations and approbation of the developed normative criteria].

Objective: Clinical approbation of previously obtained normative criteria for evaluating erectograms using the Androscan MIT hardware complex, as well as comparing the monitoring indicators of nocturnal penile tumescence (NPT) with the results of the standard questionnaire International Index of Erectile Function-15 (IIEF-15).

Materials And Methods: The study included 120 patients aged 19 to 72 years. Erectile function was assessed using the IIEF-15 questionnaire and the Androscan MIT hardware complex. To assess erectile function, previously developed normative criteria for the relative increase in the diameter of the penis (OP) and the duration of NTP were used. Statistical data processing was carried out using the STATISTICA 12 software. A systematic literature search on the normative criteria for monitoring NTP was carried out in the Medline database.

Results: After performing androscanning, patients were divided according to the degree of ED: there were 12 patients without ED, 58 patients with grade 1 ED, 27 patients with grade 2 ED, and 23 patients with grade 3 ED. According to the results obtained, a positive correlation was found between the OD value and the results of the IIEF-15 questionnaire.

Conclusion: The obtained data on the correlation between the results of the IIEF -15 questionnaire and the NTP monitoring parameters are consistent with most of the currently available foreign data.
