A series of 24,388 consecutive autopsies yielded 148 cases of amyloidosis, for which the associated diseases were tabulated. 13 solid primary malignancies were found in eleven patients, including one mucoepidermoid cancer of the parotid and one thymoma; two out of eleven had evidence of pyelonephritis. Five patients suffered from past or present renal adenocarcinoma, the most common carcinomatous cause of amyloidosis. Systemic amyloid deposits thus occurred in 2.1% of autopsied patients with renal carcinoma, but showed no obvious correlation with tumor stage or histologic type. Details are presented of an unusual case of hypernephroma producing a stable bronchial metastasis cuffed by nodular amyloid and dissociated by a lymphoid infiltrate containing plasma cells. The occurrence of systemic amyloidosis in non-hematologic malignancy thus appears to be a rare event, which, especially in the case of renal cancer, is assumed to be due to amyloid-fibril protein AA.

Surgically-placed urinary conduits remain the most common form of long-term, supravesical urinary drainage. We reviewed CT scans of 16 patients with ileal loops examined during a 3-year period to assess normal loop anatomy and associated pathological conditions. Computed tomography was indicated when conventional studies were considered inadequate. Indications for studies were suspected tumor recurrence in 12 (75%) and abscess localization in four (25%). The normal CT ileal loop lies medial to the cecum at the level of the sacral promontory. In 12 patients, CT identified abnormalities related to ileal loop diversion. Clinically unsuspected nontumorous complications (xanthogranulomatous pyelonephritis, pelvic abscess, and peristomal hernia) were detected by CT in patients with suspected tumor recurrence.

Between 1975 and 1982, 39 patients underwent total cystectomy and urinary diversion at our hospitals. The type of urinary diversions were ileal conduit (32 cases) and ureterocutaneostomy (7 cases). Preoperative irradiation was used in 10 patients. The postoperative mortality rate was 2.6%. Early complications occurred in 38.5% and included wound infection, acute pyelonephritis, intestinal obstruction, pelvic infection, intestinal leakage and/or medical complications. Ureteroileal stricture was most frequent in late complications. Over-all relative 1-, 3-, and 5-year survival rates were 92.4, 56.6, 41.7%, respectively. Survival was dependent on the stage and the grade of the tumor. No significant difference was found between the older (greater than or equal to 65 years old) and the younger (less than 65 years old) groups.

A case of xanthogranulomatous pyelonephritis associated with 'small' renal carcinoma is presented. The urinary sediment showed atypical cells, suspect of malignancy. The renal neoplasm measured only 1.5 cm, had the typical papillary configuration of a 'small' renal carcinoma and was composed of atypical cells with finely granular cytoplasm and hyperchromatic nuclei. The xanthogranulomatous pyelonephritis was a primary lesion, spacially separate one from the other. The clinicopathological features of reported examples of coexistence of these diseases have been reviewed.

The adenocarcinoid tumor is a potentially malignant neoplasm usually arising in the appendix. We describe a 55-year-old woman with a ureteroileal conduit in place for 12 years who suffered obstruction of the ileal segment of the conduit, with recurrent pyelonephritis and abdominal pain. Pathological examination of a segmentally resected portion of the conduit revealed a submucosal proliferation of nests of argentaffin/argyrophil cells and large, mucin-distended goblet cells. The patient showed no evidence of metastasis and has done well to date following excision. A discussion of neoplasms arising in the ureteroileal conduit is included.

The results obtained in a series of 233 subjects who underwent surgery for total cystectomy and ureterosygmoidostomy for carcinoma of the bladder are analyzed. The immediate and long-term results, the complications and length of survival, both in general and in relation to the stage of the neoplasia, have been considered. The surgical death rate was 7%. Survival, taking all cases into account, was 80% after 1 year, 55% after 3 years, 36% after 5 years and 8.3% after 10 years. Significant differences in survival were found among those patients with pathologic stage PIS-P1-P2 and those with P3-P4. From a survival of 64% after 5 years in the first group, we pass to 23% for P3 and 0% for P4. The precocious complications are anastomosis stenosis (1.8%), uro-fecal fistulae (1.8%) and urinary fistulae (1.4%). Late complications are anastomosis stenosis (13.6%), pyelonephritis with episodes of fever (19.3%), severe acidosis (1.8%) and kidney stones (1.8%).

(6R-[6alpha,7beta(R)])-7-[(hydroxyphenylacetyl)amino]-3-([(1-methyl-1H-tetrazol-5-yl)-thio]methyl)-8-oxo-5-thia-1-azabicyclo[4,2,0]oct-2-ene-2-carbonic acid (cefamandole) levels have been determined in human renal tissue, serum, and urine of 17 patients undergoing therapeutic nephrectomies after 3 i.v. applications of 2 g cefamandole. As far as possible levels of renal cortex and renal medulla were investigated separately. The concentrations of the antibiotic in human renal tissues, removed in the interval from 2 h 10 min to 6 h 25 min after last application of the drug, were distinctly above the minimum inhibitory concentrations of most bacterial strains responsible for urinary tract infections and cases of chronic pyelonephritis. Concentrations of the drug were usually lower in renal parenchyma alterated by chronic inflammatory processes than in "normal tissue" of tumor kidneys. With separate determinations of drug levels in the cortical and medullary regions concentrations of the drug were usually higher in the cortical part of the kidney.

The diagnostic work-up of the urologic patient must be tailored to the presenting symptom complex, carefully selecting from the many modilities available, those most likely to establish the diagnosis and extent of the suspected lesions. Intravenous urography is the most rewarding initial procedure for many presenting symptoms, including suspected masses, pyuria, hematuria, and flank pain. Nuclear imaging is particularly effective in differentiating renal lobulations from true masses, in demonstrating parenchymal scarring in chronic pyelonephritis when the IVP is equivocal, and in assessing the decrease in perfusion and function in obstructive nephropathy when the IVP is indeterminate. It is the preferred procedure for acute renal infarction and acute tubular necrosis and has a greater sensitivity of detection for renal trauma than the IVP. Gallium-67 renal imaging appear helpful in the detection of occult pyelonephritis or interstitial nephritis. However, it cannot differentiate focal acute pyelonephritis from abscess or abscess from neoplasm. Ultrasoneography is the initial procedure of choice in the differentiation of cystic from solid renal masses and in anuria or oliguria. When a kidney fails to visualize by IVP or nuclear imaging, it can confirm or rule out obstruction. In upper tract infections, it may demonstrate renal or perirenal abscess. Although retrograde pyelography is performed less frequently in recent years, it remains extremely useful in confirming and relieving obstructive uropathy and in delineating tumors of the collecting system. Computed tomography effectively demonstrates hydronephrosis, renal abscess, tumors, and cysts and retroperitoneal involvement. More experience is needed to judge the efficiency of "dynamic" CT for the quantification of renal function. Renal angiography remains invaluable as a secondary procedure (as opposed to initial screening) in renal trauma, vascular anomalies, and in renal tumors to delineate the anatomy of the arterial supply and possible renal vein involvement.

Over the last 22 years, we have encountered 34 examples of a highly aggressive neoplasm with a microscopic morphology that is highly predictive of finding sickled erythrocytes in the tissue. With the exception of one patient, all are believed to have had sickle cell trait or, in one case, hemoglobin SC disease. These 33 patients are the subject of this report and, where their race was known, they were all blacks between the ages of 11 and 39 years. Between the ages of 11 and 24 years, males predominated by 3 to 1. Beyond age 24, however, the tumors occurred equally in men and women. The dominant tumor mass was in the medulla and ranged from 4 to 12 cm in diameter. Mean size was 7 cm; median, 6 cm. Peripheral satellites in the renal cortex and pelvic soft tissues, as well as venous and lymphatic invasion, were usually present. The lesions exhibited a reticular, yolk sac-like, or adenoid cystic appearance, often with poorly differentiated areas in a highly desmoplastic stroma admixed with neutrophils and usually marginated by lymphocytes. The tumors had usually metastasized when first discovered, and none was confined to the kidney at the time of nephrectomy. The mean duration of life after surgery was 15 weeks. These tumors probably arise in the calyceal epithelium in or near the renal papillae, the same site that produces the more familiar picture of unilateral hematuria in patients with sickle cell trait. We have concluded that renal medullary carcinoma represents another example of renal disease associated with sickle cell disorders. The other six are unilateral hematuria, papillary necrosis, nephrotic syndrome, renal infarction, inability to concentrate urine, and pyelonephritis.
