Abdominal pain or hematuria were the main symptoms in five patients with hydrocalicosis of the right upper renal calix. Evidence of vascular compression of the infundibulum was present in the excretory urography. In patients with upper calix syndrome, periodic urinary and urographic controls are mandatory. Surgical correction is indicated only if recurrent and unendurable episodes of pain, urinary infections, or stone formation occur.--B.

M. Madorsky, R. Fennell, E. Garin, and G. Richard. J Ural 117~505-507 (April), 1977. Children with ileal conduit urinary diversion usually have adequate postoperative assessment of glomerular but not tubular function. Deterioration of tubular function usually precedes deterioration of glomerular function in most urologic conditions. The methodology of performing glomerular and tubular function studies on an outpatient basis has been developed. A 5-hr renal function evaluation that includes urea and creatinine clearance, fasting concentration test, water loading test, blood gases, and serum electrolytes, are obtained. The functional data on 31 children with an ileal conduit forms the basis of this study.-George Holcomb Complications of Urinary

1977. Complications of urinary tmdiversion may be divided into those related to patient selection and those pertaining to the operation. A detailed understanding of the anatomic and physiologic alterations in the dynamics of urine transport is an essential prerequisite for the selection of suitable candidates. Two illustrative cases emphasize the necessity for complete evaluation of the upper and lower urinary tracts as well as meticulous attention to the intraoperative detail.-George Holcomb Strictures of the Heal loop. 8.

Of 238 pediatric conduit patients, I5 had obstructing strictures between the proximal end of the conduit and the peritoneal side of the abdominal wall. It was observed that loop strictures occurred late and were usually clinically silent. Their etiology is inflammatory rather than ischemic. and a local immunosuppressive effect of urine may also play a role. Periodic urography, continued indefinitely, is the only certain method of early detection. George Holcomb Microanatomy

and 1. He/in. J Ural 117:353-354 (March), 1977. The microscopic appearance of 37 distal ureteral resection speciment from 27 children with recurrent urinary tract infections and vesicoureteral reflux are compared to postmortem specimens of 51 distal ureters from 28 children with no history of urinary tract disease. The degree of fibrosis and inflammatory change varied a great deal in both groups, and it was not possible to find any difference between them- George Holcomb Venographic localizo~ion of the Non-palpable Undescended Testis in Children. R. M. Weiss,
M. G. Glickman, and 6. Lytfon. J Ural 117:513-515 (April), 1977. In cases of bilateral non-palpable undescended testes in which human chorionic gonadotropin stimulation has shown the presence of testicular tissue. and in cases of unilateral undescended testes, selective non-palpable transfemoral gonadal venography has been used for the preoperative localization of the non-palpable testis. Gonadal venography has proved to be accurate and safe and has aided in the determination of the extent of surgical exploration in nine children with 12 nonpaipable undescended testes.- -George Hofromb Torsion of the Testis.

A series of 56 proven cases of torsion of the testis treated at the Royal Newcastle Hospital, New South Wales, Australia, between 1950 and 1975 is analyzed with a view to determine the fate of the testis in relation to the duration of symptoms. Fifteen patients were treated by orichidectomy, 26 of the remaining 41 patients were assessed. If the duration of symptoms is less than 12 hr the outlook is excellent. between I2 and 24 hr survival of the testis is possible, over 24 hr the testis is most likely to be beyond
