De ischuria theses

XXII.
The cause of the disease, the constriction, must be relaxed; the obstruction must be opened, which is done sometimes by itself, sometimes once the cause is removed.

XXIII.
The proximate cause is removed either by relaxing the passages or by propelling or extracting the material.

XXIIII.
The passages are relaxed so that the body or humor, once they are dilated, can either descend into the bladder or be brought out of the body.

XXV.
This is done by taking moist and unctuous things internally, and especially by injecting them or applying them externally.

XXVI.
The cause is propelled if those things are taken which either diminish the stone, dissolve the blood clot, or cut through the pus.

XXVII.
But especially if, by inserting a catheter into the passage of the bladder, or a finger into the anus, the stone is pushed back into the bladder or other impediments are removed.

XXVIII.
A stone is removed from the capacity of the bladder or its neck if it is small, by propulsion or suction; if it is large, by surgery.

XXIX.
By reason of the antecedent cause, the body should be made clean and kept pure.

XXX.
The more serious symptom, that is, the urge to urinate, ceases spontaneously if we remove the cause; it hardly draws the method of cure toward itself in any other way.
