, at or near whichmany pathological conditions are apt to present them-selves. The ureteral openings should be carefully noted,and if possible the appearance of the urine as it passesfrom them should be observed. The upper three-fourths of the bladder can be mostreadily investigated, the lower fourth being more difficultto see in cases where enlargement of the prostate ispresent. When the examination has been completed theelectric circuit is opened and the instrument withdrawn.When not surrounded by fluid the cystoscope rapidly 312 A Manual of Practical Medical Electricity becomes heated, and it is imperative, therefore, both whenintroducing and withdrawing the instrument, to shut offthe electro-motive force. An ansesthetic is not invariably required, but innervous patients or in sensitive bladders anaesthesia isadvantageous. Time has proved the great value of cystoscopy, andgenito-urinary surgery has advanced enormously, bothas regards diagnosis and treatment, since its introduction.

Fig. 135.—Phantom for Cystoscopic Practice. In particular, perhaps, this applies to renal surgery, assurgeons now have a means of differentiating renal fromVesical haematuria with certainty, and also they are ableto tell which is the affected kidney. Further, the intro-duction of cystoscopes to enable catheterization of theureters to be performed has facilitated the examinationof the urine from each kidney, so that the functionatingpower of each can be determined. Several forms of cysto-scope can be used for this purpose, but one of the best isthat known as Albarrans, which has the ureteral catheter Electro-Therapeutics 3^3 on the same side as the hght, and by a special joint canhave its angle changed while within the bladder. The urethroscope for examination of the urethra has thelight external. It is valuable in cases of gleet, as in in-tractable cases the exact site of the lesion may be seen,and topical remedies be applied under the eye of thesurgeon. Fig. 135 represents the dumm
