A case of renal pseudotumor in a 47-year old female is reported. She was admitted with the complaint of right flank pain. Intravenous pyelography showed filling defect in right renal pelvis and spreading deformity of calices with compression of infundibuli. Ultrasonography and computed tomography demonstrated round renal mass. Since possibility of hypovascular tumor was not completely ruled out by right selective renal angiography, subsequently performed, then right nephrectomy was done. Bisected specimen revealed mal position of renal lobe (lobar dysmorphism). Microscopic appearance showed normal renal parenchyma. The literature is also reviewed.

A 68-year-old woman was hospitalized complaining of right flank pain. The excretory pyelogram revealed that the right kidney was hydronephrosis, and a retrograde pyelogram showed stringy filling defects in the middle portion of the right ureter. Suspecting a right ureter tumor, a right ureteronephrectomy was performed. The pathological diagnosis was ureteral cholesteatoma which is a rare condition with reports of only 9 cases in the Japanese literature. Although the possibilities of malignant change has been debatable, long term follow up would be mandatory.

Three cases of metastatic renal tumor are reported. The first case was of a 61-year-old man, who had a Miles' operation for rectal adenocarcinoma 30 months before, and suffered from high fever and right flank pain. Right nephrectomy was carried out and the kidney was found to contain an adenocarcinoma identical to the one previously removed from the rectum. He died 1 year after nephrectomy. The second case was of a 35-year-old man, who had undergone left pneumonectomy for a squamous cell carcinoma of the bronchus. One month later, he was readmitted with cloudiness of consciousness and high fever. Investigations revealed right kidney, adrenal gland and brain malignancies, and which were ectomized totally. On pathological examination all ectomized tissues were metastatic squamous cell carcinoma. He died 1 month after the second operation. The third case was of a 48-year-old man, who had undergone left pneumonectomy for a squamous cell carcinoma of the bronchus. One year after pneumonectomy, abdominal CT showed a left renal tumor. Right nephrectomy was performed and pathological examination revealed a metastatic squamous cell carcinoma. He is now alive 4 months after nephrectomy without any sign of recurrence. A total of 136 cases of metastatic renal tumors including 38 cases from the Japanese literature, are reviewed.

The success of cancer therapy depends on the destruction of all viable cancer cells in the primary site, as well as in metastatic areas. Surgery alone can do little for the patient whose tumor has produced distant involvement except in those situations where surgical excision, radiotherapy, chemotherapy, or immunotherapy can be relied on to eradicate metastatic disease. Because of the paucity of systemic therapy for renal cell carcinoma, an aggressive surgical approach to the primary tumor is justifiable when all metastatic lesions can be excised or otherwise definitively treated and in experimental protocols in which adjuvant therapy of possible benefit can be combined with palliative nephrectomy. There is no evidence, however, in reported studies to suggest that routine palliative nephrectomy in patients who will not be offered adjuvant systemic therapy or radiation is beneficial. Such practice is also associated with a higher incidence of complications and mortality than is expected for resection of localized renal cell carcinoma. For these reasons, it is reasonable to recommend adjunctive nephrectomy only in certain selected instances, which include (1) the control of a patient's current symptoms related to the primary disease, for example, flank pain, hematuria, fever and toxicity, anemia, erythrocytosis, and hypercalcemia; (2) nephrectomy with the excision of a solitary metastasis; and (3) the patient who is willing to undergo experimental therapy, part of which involves removal of the primary tumor.

A 61-year-old male, who had undergone operation of esophageal carcinoma 11 months earlier, was admitted for left flank pain and high fever. Intravenous pyelography showed a space occupying lesion in the upper half of the left kidney. Computed tomographic scan showed an irregular low density area in the upper half of the left kidney. Angiograms revealed a hypovascular mass with encasement vessels in the same site. Left nephrectomy and paraaortic lymph node biopsy was performed. Pathological examination revealed a metastatic squamous carcinoma from the esophageal carcinoma. Chemotherapy was conducted, but he died 2 months later. Autopsy revealed recurrence in the retroperitoneum, and no metastasis in the right kidney. The literature on secondary renal tumor is reviewed.

A 47-year-old woman experienced sudden onset of severe left flank pain. By computed tomography (CT) and arteriography, her condition was diagnosed as a ruptured angiomyolipoma of the left kidney. She did not have tuberous sclerosis. Using polyvinyl alcohol foam (Ivalon) particles, immediate embolization of a main artery feeding the tumor--the posterior branch of the left renal artery--was performed. Three months after embolization, intravenous digital subtraction angiography (IVDSA) showed this main feeder was still occluded. This case and others encountered in our review of the literature underscore the usefulness of therapeutic embolization for renal angiomyolipoma.

A case of bilateral renal angiomyolipoma is reported. A 21-year-old female visited our hospital with the complaint of severe left flank pain and macroscopic hematuria Bilateral renal mass was suspected from the intravenous pyelography. CT scan revealed bilateral renal angiomyolipoma accompanied by retroperitoneal bleeding. There were no symptoms or signs of tuberous sclerosis. Left partial nephrectomy and right tumor enucleation were performed uneventfully with no recurrence during 4.5 years of follow-up. Several case reports of renal angiomyolipoma have been documented; we sum up these cases with special consideration as to treatment. In the majority of the cases, nephrectomy has been performed after retroperitoneal bleeding. We emphasize that in some cases it is favorable to carry out renal-tissue-conserving operation before the occurrence of the bleeding, because the angiomyolipoma tends to rupture easily.

A 59-year-old woman was admitted to our clinic with the complaint of left flank pain. Excretory urogram showed left hydronephrosis. Computed tomographic (CT) scan and renal angiography showed a left renal capsular tumor. Histological specimen obtained by a sure cut needle suggested malignant lymphoma. She was treated with a combined treatment of 8 MHz radiofrequency hyperthermia in a total of 10 sessions and 5,440 rads irradiation for 5 weeks. After the treatment, CT scan showed 92% tumor regression. After that, a recurrent tumor in left shoulder muscle became manifest. She received combination chemotherapy with 3 courses of ABEP regimen (aclacinomycin, cytosine arabinoside, etoposide, prednisolone) and 7 courses of ACOPE regimen (adriamycin, cyclophosphamide, vincristine, prednisolone, etoposide) and complete remission was obtained.

A case of renal angiomyolipoma originating from polycystic kidney with horseshoe kidney is reported. A 32-year-old woman visited our hospital with the complaint of proteinuria. with computerized tomographic scan and further examinations the patient was diagnosed as having renal angiomyolipoma with tuberous sclerosis. The tumor originated from a polycystic horseshoe kidney. Three weeks later, she complained of right flank pain and was diagnosed with spontaneous rupture of the angiomyolipoma. Right heminephrectomy was performed and histological examination confirmed the preoperative diagnosis. Some discussion is made on the characteristics and treatment of renal angiomyolipoma, and the statistics on renal diseases with tuberous sclerosis in Japan are presented.

A tumor thrombus in the vena cava (infrahepatic) was identified in a 70-year-old male with chronic obstructive lung disease, and right nephrectomy and thrombectomy were performed successfully. Therefore, he enjoyed good health for 6 months until he developed bone metastasis in the vertebrae and upper gastrointestinal bleeding. In another case of a 51-year-old male who presented with a mass in the posterior part of the chest; the biopsy specimen of the mass was reported to at least resemble renal-cell carcinoma. Subsequently, he underwent right nephrectomy and thoracotomy to remove the mass. He has since led an uneventful life without tumor recurrence. In our hospital from 1971 to 1980, 9 cases of renal-cell carcinoma have been experienced, including the above 2 cases. Their average age was 49.4 years, with ages ranging from 34 to 70 years. Seven patients presented with gross hematuria, and 2 patients, with flank pain. All 9 cases, all of whom underwent radical nephrectomy, were diagnosed pathologically as having renal cell carcinoma. The right side was involved in 3 cases, and the left, in 6 cases. The upper pole of the kidney was involved in 2 cases the middle in 1 case, and the lower in 5 cases. The mean 5-year survival rate was 69.2% and was closely associated with the tumor stage.
