—Hanley and Steel1 discuss solitary ectopic kidney and add 2 cases which make a total of 44 cases reported. Since publication of their paper, 2 additional cases have been described by Mays, Schrieber and Smith. Every female whose case is recorded had some associated genital anomaly; this fact is good reason for a full urologic investigation in all such cases. The cases were divided about equally between males and females. Few of the patients presented themselves for reasons associated with urologic problems. The most frequent symptom was pain in the lower region of the abdomen; the commonest sign was a palpable tumor. In many cases a solitary ectopic kidney is undoubtedly overlooked at operation. Appendectomy was performed on at least 3 patients. Earlier reports show that in 2 cases the solitary kidney was removed; in another case it was opened by mistake for the uterus, and another time biopsy
