Of 282 patients with invasive bladder carcinoma treated by a combined protocol of preoperative irradiation and total or partial cystectomy 84 had no residual carcinoma in the surgical specimens. Of these 84 patients who have been at risk for 12 to 149 months 59 (70 per cent) are alive.
Although spontaneous regression of metastatic renal cell carcinoma occurs it is so uncommon that it should not be considered the primary basis for recommending removal of the asymptomatic primary lesion. Such a recommendation should be made when other treatment modalitis are available to augment the factors influencing the patient-tumor interface. Spontaneous regression of a documented solitary liver metastatic lesion is reported. Removal of the residual hepatic lesion failed to prolong the patient's life.

In 2 cases of irreparable upper ureteral damage autotransplantation of the kidney with pelvioureteral anastomosis proved to be a satisfactory alternative to nephrostomy drainage or nephrectomy.
Records of 72 consecutive patients with caliceal diverticula, representing an incidence of 4.5 per 1,000 excretory urograms, were studied. Of these 72 patients, 39 per cent had a history of recurrent infections and an equal number had stone-containing diverticula. However, only 17 per cent had roentgenographic evidence of pyelonephritis. Similarity of incidence in children and adults, as well as a paucity of renal infection and scarring, supports an embryologic etiology. In our experience the need for surgical intervention is much less than is suggested in the literature.
