Abstract

勃起不全の精査のために受診した105名の患者について基礎疾患と Rigiscan による夜間陰茎硬度腫脹連続測定所見との関係について検討した. 夜間陰茎硬度腫脹連続測定所見 (以後 Rigiscan パターン) を正常, 硬度不均一, 硬度腫脹不一致, (硬度持続) 短時間, 低硬度, 平低の6型に分類した. 患者の基礎疾患は基礎疾患なし11名, 中枢神経系疾患15名, 循環器系疾患29名, 糖尿病35名 (インスリン依存14名, 非依存21名), アルコール依存5名, 悪性腫瘍7名, Peyronie 病3名であった. 基礎疾患なし群では Rigiscan パターン正常64%であり, 心因性勃起不全と考えられる症例が過半数を占めた. 循環器系疾患群では低硬度型41%, 平低型35%と硬度・腫脹が低下した症例が多いのにたいし, 中枢神経系疾患群では短時間型が60%と最も多く, 低硬度型47%, 平低型7名であり, 両者間に Rigiscan パターンの違いを認めた. 糖尿病群ではインスリン非依存患者がさまざまな Rigiscan パターンをとるのにたいし, インスリン依存患者では低硬度型, 平低型が多かった. 夜間陰茎硬度腹脹連続測定法はそのパターンの解析と他の検査結果との総合的な判定により, 器質性勃起不全と心因性勃起不全の鑑別診断のみならず器質性勃起不全の原因疾患の診断にも役立つことが期待される.

By continuous and simultaneous recording of nocturnal penile rigidity and circumferential expansion (tumescence), nocturnal penile rigidity and tumescence have been classified into 6 patterns; normal, dissociation, uncoupling, short episode, low amplitude and flat trace. The monitoring will be helpful to diagnose underlying disorders involving erectile impotence, if the pattern of nocturnal penile rigidity and tumescence are related with the disorders.<br>This study analyzed the relationship between the pattern of nocturnal penile rigidity and tumescence and associated disorders in 105 patients with erectile impotence. Of 15 patients with central nervous system disorders, 9 (60%) had a pattern of short episode of rigidity. In 29 patients with cardiovascular disorders, the patterns of dissociation, low amplitude and flat trace were the main findings and observed in 41, 41, 35% of the group, respectively. No patients with diabetes mellitus showed normal pattern. Although the group of non insulin dependent diabetes mellitus (21 patients) had various patterns of rigidity and tumescence, the insulin dependent group (14 patients) mainly showed patterns of low amplitude (21%) and/or flat trace (71%). The continuous and simultaneous monitoring of penile rigidity and tumescence will be helpful, with an integral analysis of its pattern and other examinations, for accurate diagnosis of underlying disorders of organic impotence, besides for differentiation of organic impotence from psychogenic one.
