ABSTRACT
<p><b>OBJECTIVE</b>To characterize the symptoms of neurogenic intrapelvic syndrome and the pathogenic mechanisms.</p><p><b>METHODS</b>A total of 537 patients with neurogenic intrapelvic syndrome were treated in the Takano Hospital between 2001 and 2005. Clinical data were analyzed retrospectively.</p><p><b>RESULTS</b>The mean age was 58.5 years old. There were 205 males and 332 females. There were 80 patients(14.9%) who presented with only one symptom with anorectal pain being the most common one (43.8%, 35/80). One hundred and fifty-six(29.1%) patients had two symptoms with anorectal pain and difficult evacuation being the most common combination (26.3%, 41/156). There were 144 patients (26.8%) complained of 3 symptoms and the most common combination was anorectal pain, difficult evacuation, and abdominal discomfort (30.0%, 43/144). A combination of 4 symptoms was reported in 105 patients(19.6%) with the combination of anorectal pain, incontinence, abdominal discomfort, and lumbar discomfort being the most often(65.7%, 69/105). In addition, there were 52 patients(9.7%) who had above 5 symptoms simultaneously. The frequencies of the 5 symptoms were 73.6% for anorectal pain, 27.9% for incontinence, 69.6% for difficult evacuation, 55.3% for abdominal discomfort, and 53.6% for lumbar discomfort.</p><p><b>CONCLUSIONS</b>Symptomatology of neurogenic intrapelvic syndrome is complicated. The pathogenic mechanism may be related to concurrent dysfunction of sacral nerve and pelvic splanchnic nerve.</p>
