with micturition and had not passesd urine for 8 hours. On examination of abdomen it was found that the bladder extended above the level of umbilicus. digital rectal examination revealed a large firm fixed swelling anterior to the lower part of the rectum.Catheterization was found to be impossible.the surgeon decided to relieve the condition by passing a suprapubic tube into the bladder.wat anatoimical structure lies anteriuor to the lower part of the rectum, which, if diseased, is likely to interfere with micturition?
Will surgeon's suprapubic tube cross the peritoneal cavity before entering the bladder?: Sounds like a prostate problem ergo have to place suprapubic catheter until they can operate to remove the swelling blocking the urethra which causes inability to pass urine. I do not believe the catheter crosses the peritoneal cavity because the bladder sits low and posteriorly in the pelvic cavity. Hope this helps! I am only responding to this question so I can keep track of this question to see if anyone answers such a question. I doubt it. The surgeons are the ones we have to depend on, with their knowledge and I know it is hard sometimes and we question their procedures, I do all the time. They can goof sometimes too, but they were the ones trained and schooled for many years.==== |
