Southhampton Bristol Group Cystometry Research
The problem of investigation in patients with incontinence is that virtually all urine produced leaks out of the bladder and therefore cannot be used for traditional investigative Cystometry. This study answered a few questions that are important.
1. The clamping did allow conventional testing in 30/166 post prostatectomy patients studied.n Use of the clamp did not affect vesicle filling or conduct of the test.
2. Pressure flow study flow rates were not affected when compared with the main study non-clamp group but the detrusor pressure was noted to be lower in the clamp group suggesting weaker bladder contraction.
3. The penile clamp use did not cause vesical-ureteral reflux as proved by contrast cystograms. This is important for those patients using urethral control devices as infection or damage to the proximal urinary tract could follow active reflux.
Comment:
The Bristol Group used an archaic Thomson-Walker Clamp which we would submit was less than ideal because of the general Clamp problem of circulatory impairment.
This Clamp was used for short term so this was not considered to be important.
Generally this study is good news for the Urethral Control devices because of the lack of ureteral reflux.
