Not infrequently duplication of the pelves is completein regard to separate drainage through the ureters, butcommunication between the two pelves will remain through CONGENITAL ANOMALY 299 adjacent calyces. That is to say, the upper major calyxof the lower pelvis may merge with the lower major calyxof the upper pelvis. If fluid were injected into one pelvis,it would pass through the communicating calyces into theother pelvis. It is of practical importance to determine theamount of tissue which separates the two pelves. If aconsiderable distance separates the two pelves, the ease of.

When the twopelves are in such close proximity that the calyces ap-parently overlap, bisection would be rendered more Fig. 286 the upper calyx of the lower pelvis is directlycontinuous with the lower calyx of the upper pelvis, so thatthe connecting isthmus extends between calyces instead of thetrue pelvis, as in preceding cases. Methylene-blue solutioninjected into one ureter returned through the other ureter. 300 PYELOGRAPHY With duplication of the pelvis in one kidney, a tendencytoward duplication or unusual increase in size is usuallyapparent in the other. Complete duplication of the pelvesin both kidneys with separate ureters occurs rarely. InFig. 283 the duplication of the pelves in the right kidneyis complete. The left pelvis, although incompletely dis-tended, shows evi
