Renal or ureteral diseases are often associated with gastrointestinal symptoms. In this communication, we studied the effect of renal pelvic or ureteric distension on the anorectal function in 12 healthy volunteers. A 3F balloon-tipped catheter was introduced into the renal pelvis. The balloon was filled with saline in increments of 2 ml up to 12 ml and the pressure response of the rectum and a...

The innervation of the puborectalis and external anal sphincter muscles was studied in 32 patients with idiopathic (neurogenic) faecal incontinence, 12 of whom also had complete rectal prolapse, using transcutaneous spinal stimulation, transrectal pudendal nerve stimulation, single fibre EMG, anorectal manometry, and measurement of perineal descent. Fourteen normal subjects served as controls. ...

The rectal foreign body is a rare presentation with rising incidence. We present case of 26-year-old heterosexual male an alleged history sexual assault insertion large through the anus two days prior peritonitis. After investigations, patient underwent exploratory laparotomy, removal, primary repair perforation diverting colostomy. Diversion must be considered in cases where extent anal sphinc...

cle, rather than the internal sphincter, may be injured during a PPH because it is recommended to perform the procedure two to five centimeters above the dentate line [7]. If the staple line is at the level of the dentate line and the specimen involves smooth muscle, one can conclude that an injury to the internal sphincter happened during the PPH. However, there was no change in continence, no...

OBJECTIVES The aim of this study was to correlate clinical findings of anal sphincter defects and function with a sonographic diagnosis of significant sphincter defects. METHODS This is an observational cross-sectional study on women seen 6 to 10 weeks after primary repair of obstetric anal sphincter injuries (OASIs). All patients underwent a standardized interview including the St Mark incon...

In normal subjects the length of the functional anal sphincter has been compared with the extent of sensation to light touch in the anal canal. At rest, the sphincteric zone was the longer. On distension of the rectum, a decrease in pressure in the anal canal so shortened the functional sphincter that intrarectal pressure extended down to contact the sensory zone. This mechanism may allow the s...

The function of the anal sphincters has been studied by obtaining continuous recordings of the pressure in the anal canal and the electromyographic activity in the striated sphincter muscles during expansion of the ampulla recti by means of an air balloon. Ten healthy subjects were examined before and after the striated muscles had been entirely paralysed by bilateral pudendal block, making it ...

Anorectal manometry measures the pressures of the anal sphincter muscles, sensation in rectum, and the neural reflexes that are needed for normal bowel movements. This test is mainly performed to evaluate patients with constipation or fecal incontinence but is also useful for pre/post surgical evaluation of anal sphincter tone, functional anorectal pain, pelvic floor dyssynergia and diagnosis o...
