By rotating the little wheel (k) the endof the catheter is elevated from the plane of the axis of theinstrument till its point is placed opposite the ureteralopening, and it is then pushed onwards into the ureter till itreaches the renal pelvis, when, after a short time, urine. Fig. 36. begins to trickle out of the external end of the catheter, andis collected in a glass vessel placed for that purpose. In some cases catheterisation of the ureters is easilyaccomplished. In others, considerable manipulation is re-quired in rotating the wheel to the necessary extent, and atthe same time advancing and withdrawing the catheter,before the catheter is engaged in the ureteral canal, when, asa rule, it glides onwards without difficulty, the progress ofthe catheter, which appears greatly magnified, resemblingthat of a worm burrowing in earth. In the female an anaesthetic is rarely required for thisoperation ; in the male frequently so. THE URINE SEPARATOR My friend, Mr. }. H. Wilkin, formerly House-Surgeon,St. Peters Hospital, and now of New eastle-on-T\Tie, has invented an ingenious addition to the cystoscope, for thepurpose of keeping the catheter aseptic during its introduc-tion [vide the Lancet, May 4, 1967).
