ABSTRACT
ObjectiveTo compare the nocturnal erectile function between SRPE patients and normal people. MethodsFrom July 1st， 2019 to December 15th， 2022， a clinical comparative study was conducted on 29 SRPE patients （experimental group） and 58 volunteers （control group） who visited our urology department. The Rigiscan System was used to monitor sleep monitoring time， the number of nocturnal erections and the rigidity， duration and circumference growth of the penis when the erection reached 60%～79% and 80%～100%， respectively. The patients and volunteers were asked to make written records when they woke up， and then the total number of awakenings and the number of awakenings when the penis erection reached 60% and 80% were compared between the two groups. ResultsAge was eliminated by matching. There was no statistically significant difference in sleep monitoring time， rigidity， circumference growth and duration of the penis when the erection reached 60%～79% and 80%～100%. between the two groups. In terms of sleep， there was a statistically significant difference in the total number of awakenings between the two groups［3（2 ~ 4）vs 0（0 ~ 0），P<0.01］ .And the same was true for the number of awakenings when the penis erection exceeded 60%～79% ［1（0 ~ 1）vs 0（0 ~ 0），P<0.01］and 80%～100% ［2（1 ~ 3）vs 0（0 ~ 0），P<0.01］. ConclusionRigiscan monitoring showed that there was no difference between SRPE patients and normal male in nocturnal penile erection function. Painful awakening usually occurs when the penis erection reaches 60%～79% or 80%～100%， which reveals that SRPE may be caused by abnormal sensation of nocturnal erections or pain sensitivity in some of these patients.
ABSTRACT
Priapism is a rare pathological penile erection, and there are some inadequacies in its definition, classification, diagnosis, and therapeutic strategies. In this article, we sum up our years of experience with priapism and put forward some new views and ideas about its definition, classification, pathophysiologic process, pathological change, diagnostic essentials, therapeutic measures, indications of successful treatment, and post-therapeutic rehabilitation of erectile function. We also describe the clinical features, diagnosis and treatment of some special types of priapism, such as intermittent seizure, sleep-related painful erection, and tumor-related priapism, hoping to help urologists and andrologists in the further understanding and management of priapism.
ABSTRACT
Sleep-related painful erection (SRPE) is characterized by deep penile pain accompanied with erection occurring rapid eye movement (REM) movement period. Two (47-year-old and 40-year-old, respectively) male visited with the complaint of painful penile erection occurring during sleep. They had no problems with erection during daytime sexual activities except for mild premature ejaculation in one patient. Urologic inspections revealed no focal abnormalities. Polysomnography with simultaneous penile erection monitoring showed several episodes of awakening with painful erection which are time-locked to onset of REM sleep periods. According to the diagnostic criteria in international classification of sleep disorders, each patient was diagnosed to have chronic, severe SRPE. Despite of a low prevalence of SRPE, this condition should be considered in a patient who presents with nocturnal penile. A polysomnography accompanied with penile erection recording may help confirm diagnosis.
