A 32-year-old man was admitted with a sudden onset of severe left flank pain. The abdominal and MRI showed bilateral renal tumors with left perirenal hematoma. Selective right renal biopsy under the guidance of ultrasonography revealed that right renal tumor was angiomyolipoma (AML). After performing left renal embolization of the left renal artery, left was performed. The histology of the excised specimen was also AML. This patient had visited to the other clinics in 1985 and in 1988, and was examined by CT. Accordingly, doubling time of this tumor was calculated by ellipsoid method. Doubling time in 1985-1988 was days, and that in 1988-1995 was 675 days. Growth change of left renal AML did not show curve.

A 34-year old woman was admitted for bilateral flank pain, maleolary and palpebral oedema with an insidious evolution lasting for 5 years. Urogram showed a left ureteral duplicity and a right lacunary pelvic image. MRI and echography indicated the complete modification as a renal structure as well as the presence of some bilateral tumoral formations with a nonhomogenous structure, blood diffusion and adenopathy of the renal hilum. Nephrectomy revealed white-gray tumoral nodular tumours. The histopathological test evidenced proliferations of leiomyofibromatous, angiomatous, lipomatous, cartilaginous types with a benign aspect suggesting the diagnosis of a renal dysembryoplasic tumor (hamartoma).

Renal Cell Carcinoma is the third most common malignoma in urology. Only little is known about the etiology and risk factors; the age peak lies at 60 and twice as many men than women are affected. The clinical picture presents with a wide spectrum. Over one third of all tumours are detected accidentally by ultrasound or computed tomography in asymptomatic patients. Most common symptoms are hematuria and flank pain, the classical trials including in addition a palpable mass is rare and by mo means an early symptom. Paraneoplastic syndromes include unspecific (increased blood sedimentation rate, weight loss, fever) and endocrine symptoms (hypertension, polyglobulia, hypercalcemia). Diagnosis is based on imaging procedures. By means of sonography renal cysts may be separated from solid, space-occupying tumors. For the latter CT plays a decisive role for staging, therapeutic planning and prognosis. Further radiologic investigations (angiography, MRI) are indicated only in special situations. Rarely a biopsy is necessary for the distinction between renal cell carcinoma and metastases of other primary tumors. The only curative treatment of localized carcinoma is radical nephrectomy. Partial resection is indicated in cases of a single kidney, bilateral tumors and possibly also for tumors smaller than 4 cm in diameter. Radiotherapy is only initiated for palliation of painful skeletal metastases. In case of distant metastases--mainly pulmonary--nephrectomy should only be performed if systemic treatment is planned or if local complaints (pain, hematuria leading to anemia) exist. Chemotherapeutic drugs have no influence on survival. The effect of gestagens on life quality is questionable. Adoptive immunotherapy with cytokines (Interferon-alpha, interleukin-2) appears most promising. These substances, however, not yet been introduced into routine therapy should only be used in prospective studies. Furthermore, renal cell carcinoma is a potential candidate for gene therapy. After tumor nephrectomy follow-up investigations should be performed twice a year, because of the possibility of curative surgical treatment of late solid metastases. Prognosis of tumors restricted to the organ is good. Five year survival after operation is about 90%. However, is distant metastases exist already at the time of diagnosis 5 year survival drops to less than 10%.

A 57-year-old male was admitted because of the right flank pain. The image examinations, retrogradeurography, abdominal CT and MRI, showed a mass located at the upper right ureter. Although the tumor was not typical as ureteral cancer, we could not make a diagnosis of a benign tumor by image examinations. Therefore nephroureterectomy that was surgical method for ureteral cancer was performed. The tumor was diagnosed as inflammatory pseudotumor of the ureter by histological findings. Inflammatory pseudotumor is extremely rare for ulogeital organs. And this lesion is difficult to distinguish from malignancy only by image examinations. Therefore, the surgical resection and pathological studies are necessary.

Renal insufficiency or allergic reactions for X-ray contrast agents are frequent limitations in immunocompromised hosts such as neutropenic or AIDS patients. Due to a better tolerance of contrast agents in MRI, this technique is well suited for investigation of parenchymal organs. We demonstrate an allergic AIDS patient who presented with fever and flank pain. At sonography, anechoic renal lesions were supposed to be non-complicated cysts; however, on T2-weighted MRI, the center was of high signal. Dynamic contrast-enhanced MRI of the kidneys demonstrated an enhancing rim with ill-defined margins. The lesions were supposed to be multiple bilateral abscesses. Due to the multiple dynamic contrast series, a delayed enhancement of renal parenchyma was detectable adjacent to the lesion. This was suggested as accompanying local pyelonephritis and an infectious etiology became more reliable. Aspergillus fumigatus was identified by CT-guided biopsy as the underlying microorganism. The MR appearance of this manifestation has not been described previously.

We present a case of a 30-year-old female who was evaluated for right flank pain. Clinical and diagnostic work up revealed a urinary tract infection with focal pyelonephritis of the right kidney. Ultrasound and computed tomography of the abdomen were included in the evaluation and revealed incidental finding of cystic structure at right suprarenal space. Follow-up evaluation for further characterization of cyst was performed with MRI and displayed a 4.8x4.5-cm right adrenal cyst containing dystrophic calcification, septations, and minimal nodularity. Surgical resection and histologic findings were compatible with cystic lymphangioma of the adrenal gland. Adrenal lymphangioma is a rare and benign lesion that is most often identified incidentally during radiological investigation or at autopsy. Diagnostic features of adrenal cysts including lymphangiomas are discussed.

We describe here a case in which 99mTc-Sn-N-pyridoxy-5-methyltryptophan (99mTc-PMT) scintigraphy was useful in diagnosing renal metastasis of hepatocellular carcinoma (HCC). A 62-year-old man who had undergone hepatectomy for HCC presented 6 years after initial diagnosis with left flank pain and was found on CT and MRI to have a tumor in the left kidney. Hepatobiliary scintigraphy using 99Tc-PMT was performed, and 99mTc-PMT accumulation was found in the tumor. Nephrectomy was performed and metastasis of HCC was confirmed.

This case report describes a 46-year-old man whose first symptom was an attack of acute flank pain, followed by the gradual onset neurological symptoms. We demonstrated a small nidus and serpentine signal-void area in the spinal cord by MRI and diagnosed a glomus type of spinal arteriovenous malformation (AVM). Flank pain is a rare initial finding in an adult with spinal AVM. In cases with acute flank pain, neurologists should consider spinal AVM as a differential diagnosis.

Simultaneous occurrence of renal cell carcinoma (RCC) and transitional cell carcinoma (TCC) in the same kidney is unusual. We report a 61-year-old man with ipsilateral synchronous renal adenocarcinoma and renal pelvic TCC. He was referred to our department for gross hematuria and right flank pain. CT and MRI studies revealed a 57 x 50 mm irregular and infiltrative upper right kidney mass with necrotic components. A right radical nephrectomy was done. Pathological diagnosis was a high grade tumor originating from just beneath the intact urothelium of renal pelvis and infiltrating through the parenchyma showing solid and occasional tubular growth patterns. A second tumor in close proximity to the first was reported as well differentiated RCC. This is a rare case of combined renal malignancies.

Retroperitoneal fibrosis (RPF) is characterised by inflammatory fibrotic processes affecting the retroperitoneal structures. Its prevalence of 1 - 2/200,000 makes it a rare disease. To date, there are no guidelines for the diagnosis of or therapy for the disease. If untreated, the disease may be fatal. In 2006, the Department of Urology of the HELIOS Klinikum Wuppertal undertook to establish a nationwide patient registry, which would facilitate prospective therapy trials and the drafting of recommendations for diagnostic procedures. The pathogenesis of the disease is still unclear. Since some RPF-patients present with associated autoimmune diseases, autoimmune processes are suspected to play a role in causing the disease. The presence of autoantibodies and histological similarities with vasculitis support this hypothesis. Following initial general symptoms, patients display localised symptoms (flank pain, leg oedema, abdominal discomfort), caused by the displacing effect of the fibrotic plaques. Laboratory tests show elevated ESR and C-reactive protein and in some cases a moderate anaemia. Histological examinations should be undertaken to rule out the presence of malignant tumours. Radiological diagnostics (excretory urography, CT, MRI) show a retroperitoneal mass which blocks, compresses and displaces, completely or in part, the large vessels and the ureter. Initial therapy aims at restoring the function of the affected hollow organs through the application of (ureteric) stents, followed by immunosuppressive therapy. If drug therapy is unsuccessful, surgical procedures will follow to protect the ureter from compression. In some cases, ureteral replacement or an autotransplant of the kidney may be necessary. Life-long observation of the patients is necessary, as the disease may be chronic and relapsing. Interdisciplinary and nationwide cooperation is of crucial importance to further investigate this disease.
