It is to be feared, that, were the principle of making small incisions to be generally acted upon, the distinction between dilatation and laceration, if, in the present case, such a distinction actually exists, would not at all times be sufficiently kept in view. IV. With regard to the greater size of the aper¬ ture for the passage of the calculus, which is obtained by this operation, V.acca states, that his incision is about 21 lines in length; the wound in the perinaeum measuring 8 or 9 lines, and that of the intestine about an inch. The branches of the pubes at this place leave between them a space of from 20 to 24 lines; and since the soft parts surrounding the wound are capable of being dilated, he thinks it evident, that calculi may be extracted, by the recto-vesical, of a con¬ siderably larger size than can be extracted by the la¬ teral, operation of lithotomy; and this, too, without its being necessary to divide the inferior fundus of the bladder. Professor Scarpa seems to consider the increased size of the wound, which may be obtained by perform¬ ing the recto-vesical, in preference to the lateral ope¬ ration, as of little practical importance ; both because
