A case of spontaneous rupture of renal cell carcinoma is reported. A 53-year old man was admitted with the chief complaint of sudden gross hematuria and right flank pain on December 28, 1979. On the following day, the clinical impression was right ruptured kidney, and therefore right nephrectomy was done. Pathological diagnosis was renal cell carcinoma. He received the post-operative irradiation of a total of 5,000 rads. He was seen five years later, at which time there was no evidence of local recurrence or distant metastasis of cancer. Thirty three cases of spontaneous rupture of renal cell carcinoma were collected from Japanese and English literature. Most common chief complaint is abdominal or flank pain. Excretory urography, ultrasonography, CT scan and angiography are useful, but it is difficult to diagnose preoperatively when the tumor is small. Therefore, it is important to suspect occult cancer when a reasonable cause of rupture is undetermined. In these indeterminate cases primary nephrectomy should be considered strongly.

Ultrasound examinations were analysed in 24 patients with acute renal infections (pyelonephritis, focal pyelonephritis, renal abscess, pyonephrosis). Ultrasound examination is normal in mild inflammatory involvement of parenchyma, diffuse enlargement of parenchyma with echo-poor structure is found in severe involvement of parenchyma, localized echo-poor swelling of parenchyma is seen in focal pyelonephritis. Fever and flank pain are common to acute ureteral obstruction and acute pyelonephritis and ultrasound can differentiate between these diseases. Among mass lesions ultrasound can distinguish between focal pyelonephritis and abscess but cannot differentiate between tumor and focal pyelonephritis.

Five cases of renal arteriovenous fistulae are described: four after needle biopsy of the kidney, one due to intrarenal aneurysmal rupture. One fistula closed spontaneously, the other four patients were operated on and treated by nephrectomy. 243 other cases from the literature were reviewed. The clinical manifestations involve the cardiovascular (arterial hypertension, congestive heart failure) or the urologic (hematuria, renal colic, flank pain) systems. The diagnosis is usually made by flank auscultation (which detects a continuous sound) and by use of renal arteriograms. The causes of these fistulae are numerous: congenital or acquired from biopsy examinations, trauma, surgery, neoplasia, infection, aneurysmal rupture. The usual treatment of these fistulae is a nephrectomy but selective embolization or direct surgical repair make possible, with greater frequency now, renal parenchymal preservation.

Two cases of renal angiomyolipoma with tuberous sclerosis are reported. The first was a 42-year-old housewife with complaints of left flank pain, palpable mass at the same region and in a preshock state. Ultrasonogram of the left kidney demonstrated a large echogenic mass with fluid. Preoperative diagnosis was renal angiomyolipoma with spontaneous rupture. Emergency nephrectomy and lymphadenectomy were performed. The histopathological diagnosis was renal angiomyolipoma with nodal involvements which reflects the multicentricity of the disorder. The second was a 44-year-old housewife with dull right flank pain. CT scan showed a mass in the upper part of the kidney which had an attenuation value of -60 HU. Adrenal tumor could not be distinguished from renal tumor by selective renal angiogram. Nephrectomy was performed and histopathological diagnosis was renal angiomyolipoma. Both cases remain well. We reviewed 32 cases of renal angiomyolipoma with spontaneous rupture in the Japanese literature with respect to age, affected side, presence or absence of tuberous sclerosis, preoperative diagnosis and treatment. Previous diagnoses were done with plain film, excretory urogram and angiogram. Preoperative diagnosis of angiomyolipoma was difficult or impossible, and operative procedure of choice was nephrectomy. Now CT and ultrasonogram are the specific tools in the diagnosis of angiomyolipoma. Partial nephrectomy, enucleation or observation is selected because renal angiomyolipoma is a benign tumor.

Two cases of renal angiomyolipomas in female siblings associated with tuberous sclerosis were reported. The first case was a 47-year-old housewife who visited the hospital because of severe right flank pain. Bilateral renal angiomyolipomas and hemorrhage in the right angiomyolipoma were recognized by computerized tomography, ultrasonography and renal angiography. After 2 months she had another episode of left flank pain and was diagnosed to have hemorrhage in the left renal tumor. The pain remissed by conservative treatment. Bilateral nephrectomy and hemodialysis would be necessary if she were to have a third attack. The second case was her 36-year-old sister with the chief complaint of left flank pain and genital bleeding. CT and renal angiography suggested a large angiomyolipoma in her left kidney and a small one in her right kidney. Left nephrectomy, right partial nephrectomy and hysterectomy were performed to prevent intratumoral hemorrhage. The histopathological diagnosis was angiomyolipoma of kidneys, uterus and lymphnodes of right renal hilus. Although pre-operative differentiation of angiomyolipoma from renal cell carcinoma has been difficult, recently diagnosis has become possible by CT, ultra-sonography and angiography.

Herein we report a case of perirenal encysted hematoma secondary to renal cell adenocarcinoma. A 57-year-old woman was hospitalized because of a palpable mass in the left flank. She had had an episode of left flank pain. X-ray studies demonstrated a tumor in the left kidney and a large cystic mass beneath the left kidney. The cyst was excised by nephrectomy. Histological examination of the large cyst revealed perirenal encysted hematoma secondary to renal cell adenocarcinoma. Six months postoperatively, she is now free from left lumbar pain, and alive with lung and liver metastasis.

Thirty-eight cases of carcinoma of the renal pelvis and ureter were evaluated for stage, grade, histologic type, location, presence or absence of vascular invasion, abnormalities in the urothelium adjacent to the tumors, clinical appearance, patient survival, and therapeutic intervention. A good correlation between tumor grade and stage was found in the transitional cell carcinomas. Squamous cell carcinomas were high-stage tumors and transitional cell carcinomas with prominent squamous components were of a higher stage than "pure" transitional cell carcinomas of the same grade. Vascular invasion was present in only high-grade tumors and the squamous cell carcinomas. The degree of atypia present in the urothelium adjacent to the tumors corresponded with the grade of the tumors. Hematuria, with or without associated flank pain, was the most common initial symptom in patients with these neoplasms. Survival was good in stage A neoplasms but poor in higher-stage neoplasms. Appropriate treatment for these tumors remains controversial.

A case of retroperitoneal malakoplakia is reported. A 50-year-old female was admitted with the chief complaint of right flank pain. Intravenous pyelography, computed tomography, selective iliac arteriography and abdominal echography revealed right pararenal abscess and the right renal tumor suspected. About one liter of yellowish fluid was drained from the retroperitoneal space, but no right renal tumor was found. Pathological diagnosis was retroperitoneal malakoplakia postoperatively. This is assumed to be the second case of retroperitoneal malakoplakia in Japan.

Two cases of renal angiomyolipoma without tuberous sclerosis are presented. The 1st case was a 33-year-old woman who had left flank pain and macroscopic hematuria on August 26, 1980. Physical examinations revealed a large left renal tumor, and selective renal angiograms showed the presence of a hypovascular mass located in the central to median lower part of the left kidney. Ultrasonography showed a high echogenic mass accompanied by a round low echogenic area in the left kidney. Computed tomography revealed a fatty density in the renal mass. The 2nd case was a 60-year-old woman who was incidentally diagnosed as having a right renal tumor by ultrasonography on February 18, 1982. The echogram showed a high echogenic mass in the right kidney, and the fatty density in the renal mass was determined by computed tomography. These patients underwent nephrectomy and the histological diagnosis was angiomyolipoma. The usefulness of ultrasonography and computed tomography in the preoperative diagnosis of this clinical entity and the possibility of association with renal cell carcinoma are discussed.

Forty primary renal pelvic tumors treated at our University between 1963 and 1981, were reviewed retrospectively. The conclusions of this study are as follows. Sex and age distribution of the patients were 30 males and 10 females (3: 1), and average age was 60.5 years old. The major symptoms were hematuria and flank pain; however, palpable mass was rare. The majority of patients were admitted to our clinic within 6 months from manifestation of symptoms. The major findings of IVP were non-functioning kidney and filling defect. The positive rate of urinary cytology was 46.7%. Total nephroureterectomy with bladder cuff was performed in 20 out of 32 cases. Histologically, 29 cases were transitional cell carcinoma and 4 cases were squamous cell carcinoma with renal calculi. Simultaneous urothelial tumors were seen in 10 cases, 3 in the ureter and 7 in the bladder. A subsequent ureteral tumor was found in one out of 12 cases in which ureters were resected incompletely, and 7 subsequent bladder tumors were found out of 32 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by the actuarial method was 75.9%. Among several factors, grade and stage of the tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.
