Abstract
Sleep Related Painful Erections (SRPE) are parasomnias exclusive to Rapid Eye Movement (REM) sleep, causing sleep disturbances, daytime fatigue, and impaired quality of life. Due to a lack of standardized management, we developed a diagnostic and treatment pathway for this rare condition at our institution. Patients diagnosed with SRPE from 2017–2024 by strict criteria were recruited into our novel pathway. This included a comprehensive diagnostic panel to exclude potential confounding causes of penile pain through history, clinical examination, laboratory tests and imaging studies. Once SRPE is diagnosed a stepwise approach of initiating Baclofen (10 mg daily at night), followed by polysomnography (PSG) (to explore sleep architecture and implement sleep medication and/or treat obstructive sleep apnoea accordingly) and pelvic floor physiotherapy (PFP) (to target pelvic floor hypertonicity). Symptoms were evaluated using a dedicated questionnaire during clinic follow-up. Patients achieving a symptom-free period of >6 months were discharged. Twenty patients with SRPE (mean age 46.2 ± 11.6 years) were included. The mean delay to referral was 3.5 ± 3.1 years, with a mean of 3.3 ± 2.1 SRPE episodes per night (range 1–7) lasting 33 ± 23.7 minutes. 85% of patients completed most of the pathway. Baclofen was administered to 17 patients (10–80 mg at night), 17 underwent PSG, and 9 had PFP assessment. Baclofen benefited 70.6% of patients: 35.3% managed with Baclofen alone, 52.9% required additional sleep medication, and Baclofen was replaced by Etilefrine (5–15 mg at night) in 11.8%. PSG findings included fragmented sleep (76.5%), REM sleep abnormality (47.1%), and mild sleep apnoea (41.2%). Among those assessed for PFP, 66.6% had abnormal pelvic floor muscle tone and initiated PFP. After 3.5 ± 1.9 years of follow-up, 45% were successfully discharged and 55% are still on follow-up and experienced symptom improvement. This multimodal pathway offers a promising framework for managing SRPE.
