A report is given on a 42-year-old female patient with a ureteropyelokaliectasis in a solitary left kidney with a calyx stone in the middle group of calyces. An intramural arteriovenous haemangioma in the prevesical section of the ureter was found to be the cause of urinary stasis. After fitting a pull-through nephrostomy and removing the calyx stone the affected part of the ureter was resected and a ureterocystoneostomy was carried out with good late results.

The occurrence in the same young patient of three synchronous tumors deriving from different embryogenic tissues and without a clear correlation with a common etiopathogenic factor is very unusual. We report a case of a Caucasian woman submitted to wide resection of a large retroperitoneal liposarcoma and right radical nephrectomy for suspected tumor infiltration. Histological examination of the right ureter and renal pelvis showed the presence of a multifocal urothelial carcinoma that was clinically asymptomatic. Two months later, during follow-up, chest X-ray and computed tomography documented a coin lesion of the upper left lung, confirmed by positron emission tomography. This nodule was surgically removed and examined histologically, resulting in a diagnosis of sclerosing hemangioma. The patient is alive without evidence of recurrent disease.

Attention is called to the difference between the pathologist's and the radiologist's point of view. The reasons for this difference are discussed with special emphasis on renal tumours.Classification of renal tumours. The first main groups are innocent and malignant. Are these really clear-cut or do they blend into one another? The commoner innocent renal tumours are adenoma, fibroma, myoma, lipoma, and angioma. These are rarely of any clinical importance but adenoma is a possible source of hypernephroma. Many elaborate classifications of cancer of the kidney have been proposed but the following four groups are sufficient for most puposes: Carcinoma, hypernephroma, sarcoma, and teratoid tumours.Much the commonest malignant renal tumour in adults is the hypernephroma, thought by Grawitz and others to be derived from ectopic adrenal rests. There is still no agreement concerning their origin but three views are held at the present time: (a) All are carcinoma of renal tubules. (b) Some are derived from renal tubules and some from ectopic adrenal. (c) All are formed from adrenal tissue. These views are discussed with special reference to material in St. Mary's Hospital Museum, and it is suggested that the first view is the most probable although the second cannot be excluded.The teratoid tumours are the commonest in infants and swine. The differences between them and hypernephromata are described. The renal Pelvis, ureter, and bladder all have tumours of the same type and can conveniently be considered together. Connective tissue tumours, both innocent and malignant, are very rare. Papilloma and carcinoma are rare in the pelvis and ureter, but commoner in the bladder. The relation between these two tumours is discussed.

Hemangiomas are benign vascular tumors. They are the prerogative of the liver and skin. And genitourinary localizations are rare and have only been rarely reported in the prostat, bladder, ureter or the perineum. In the light of published cases, urethral hemangiomas are mostly found in males. Few cases of hemangioma in the female urethra were reported. We report a cavernous hemangioma of the urethra in a 61 years old patient who presented bleeding from the urethra and micturition disorders. Physical examination revealed a tumor 3 cm x 2 polyploid arising from the terminal urethra (urethral hemangioma). We performed surgical resection of the tumor, along with bladder drainage. The postoperative course was simple. We update through a review of the literature aspects of the diagnostic and therapeutic care of the urethral hemangioma.

Ureteral hemangioma is a rare entity and few cases have been reported in the literature. Nearly all cases are diagnosed on pathologic examination postoperatively. In this study we report a 22 years young male patient presented with left-sided flank pain and hematuria. He underwent computed tomography, cystoscopy, left retrograde pyelogram, left side ureteroscopy, and urine cytology. Ureteroscopy showed a left upper ureteral narrowing with bulging mass above it. Robot-assisted segmental ureterectomy with end-to-end anastomosis over 6/26 Double-J stent was done and histopathologic examination of excised ureter reported ureteral hemangioma.
