尽管直肠突出常见于排尿机能障碍的妇女,但在已提出的引起妇女尿潴留的众多学说中,直肠因素却很少引起人们的注意。方法:通过直肠及膀胱的同步放射线显影检查,直肠内压及膀胱内压的同步监测和耻骨直肠肌肌电图的监测,可在排便及排尿时同时对直肠及膀胱进行研究。此项研究意外发现许多妇女在排尿时耻骨直肠肌收缩不协调。研究对象是16名患有慢性便秘的妇女,平均年龄45岁(21～83岁)。排尿正常组6名,其中仅1例耻骨直肠肌收缩不协调。排尿异常组10名,即使增加腹压也不能正常排尿,除2名外其他人耻骨直肠肌收缩均不协调(F检验P=0.02)。直肠突出在排尿异常
Although rectal prominence is common in women with voiding dysfunction, the rectum has received little attention in many of the many theories that have been proposed to cause urinary retention in women. Methods: Synchronous radiographic examination of the rectum and bladder, simultaneous monitoring of intra-rectal pressure and intravesical pressure, and monitoring of the puborectalis EMG were performed to study both the rectum and the bladder during defecation and urination. The study unexpectedly found that many women had inconsistent contractions of the puborectalis muscle during urination. The subjects were 16 women with chronic constipation, with an average age of 45 years (21-83 years). Urine normal group of 6, of which only 1 case of puborectalis muscle contraction is not coordinated. Urination group 10, even if the increase in abdominal pressure can not be normal urination, except for 2 other people were not syngeneic puborectalis contraction (F test P = 0.02). Rectal protrusion is abnormal in urination
