    What is a psi!? Same as cubic elephant per circular mil foot?

    The pressure needs to be below 40 cm H2O (about 40 hPa or "0.5 psi"). The pound is unit of mass not force so psi is ill-defined and is not pressure. The use of a head of mercury or water is also ill-defined, but historical. To be strictly correct they should be using hPa now rather than cm H2O.

    A transurethral external sphincterotomy will keep bladder pressure low and requires follow up urodynamics in case it scars over.

    Higher injury then they need to take out bladder neck too. If you are older they may also need to take out lobes of the prostate.

    The problem with using pound mass as a unit of force is, do you use a g of 32 ft/s2 or the actual value.

    The poundal per foot squared is the rational US only unit of pressure. In the rest of the world, Newton per metre squared or Pascal is used.

    The kgf is ill-defined is g 10 m/s2 or 9.80665 m/s2? With a kgf/cm2 it is 10 (bar), but in other use, the actual value is used.

    In the Navy the pound-force was presumed at 32 ft/s2 and the slug was the mass unit. This was used in ballistics, but never by professional engineers. The engineers left the error-prone conversions to the Navy.

    That is the unit of measure used for and measured by urodynamics machines.

    Not necessarily. I have seen sphincterotomies done for this purpose, and it is not always successful, even if repeated after scarring or regrowth occurs. Sphincterotomy is also often done to try to reduce the amount of residual urine, but it does not always help with that either. It is a burn your bridges procedure though, as you will definitely leak more urine after you have had this procedure done, and have to wear a condom catheter 24/7.

    . The level of injury has nothing to do with it. It has to do with whether or not the internal sphincter opens when the bladder contracts. For some it does, for some it does not. If a man has prostatic hypertrophy (common with aging) then a transurethral prostatectomy (TURP) may be needed as well, but this does not replace nor need to be done with a sphincterotomy.
