Sleep-Related Painful Erections-A Case Series of 24 Patients Regarding Diagnostics and Treatment Options.

BACKGROUND

Patients with sleep-related painful erections (SRPEs) have deep penile pain during nocturnal erection that wakes them up and disturbs their nights of sleep. This rare parasomnia is poorly recognized by general practitioners and by urologists and sexologists.

AIM

To gain more insight into diagnostics and therapeutic options.

METHODS

Data from a series of 24 consecutive patients who presented with SRPEs at the outpatient clinic from 1996 to 2015 were retrospectively analyzed. Additional questionnaires were completed to complement data and to obtain information about follow-up. Long-term treatment efficacy of baclofen was assessed using the Wilcoxon signed rank test.

OUTCOMES

SRPEs were not associated with urologic, surgical, or psychiatric history or with serum testosterone levels. The mean doctors' delay was 3.5 years. 14 of the 24 patients were treated with baclofen (10-75 mg). In 11 of them, complete remission was observed within a few weeks. 2 of the 3 remaining patients noticed a slight improvement of SPRE symptoms and only 1 patient experienced no effect at all. After an average follow-up of 4.5 years, only 41.6% of patients who had used baclofen were satisfied with their SRPEs. The others (58.4%) were dissatisfied, mostly owing to relapse of symptoms after the discontinuation of baclofen. Other treatment forms were applied sporadically, with strongly varying results.

CLINICAL IMPLICATIONS

This overview of SRPE contributes to a better clinical understanding and recognition of the phenomenon and provides new, more constructed advice about therapeutic implications, especially concerning the use of baclofen.

STRENGTHS AND LIMITATIONS

This study provides a systematic overview of a relatively large series of patients with SRPE, which provides substantiated treatment advice. However, treatment efficacy was based mainly on the patients' subjective perception and it was not possible to compare the results of baclofen with other forms of pharmacologic treatment, because these alternative drugs were applied only sporadically. Nevertheless, this study is directional for future research.

CONCLUSIONS

This study confirmed a long doctors' delay in patients with SRPE. There was no association between SRPEs and comorbidity and total serum testosterone levels. Treatment with baclofen proved successful and safe in the short term. Long-term feasibility needs further investigation. Vreugdenhil S, Weidenaar AC, de Jong IJ, van Driel MF.
