A man with crossed, non-fused renal ectopia had carcinoma of the distal ureter, leading to hydro-ureter, hydronephrosis and urinary infection. Crossed ectopic kidneys are more disease-prone than are normal kidneys. Complicating disorders are discussed, the value of thorough urologic investigation is stressed and the incidence of tumour of the upper urinary tract in crossed renal ectopia without fusion is reviewed.

A unique case is presented of a child with crossed-fused renal ectopia, in which the renal pelves joined into a common pelvis drained by a single ureter.

A case of xiphoomphaloischiopagus tripus conjoined twins is reported. Particular emphasis was paid to the large abdominal wall defect that would be produced by separation, and the complications resulting from the use of intraperitoneal Silastic tissue expanders are described. As a result of adequate tissue expansion and the use of a vascularized pedicle graft from the fused limb, primary abdominal wall and pelvic closure was possible without complications of wound healing. The consistent finding of a shared lower urinary tract with one ureter from each infant entering each bladder should be anticipated in this type of twinning.

A case of fused pelvic (discoid) kidney drained by a superiorly inserted single ureter is presented. This is the twentieth case of fused pelvic kidney, and the fifth case in which drainage was carried out by a single ureter, to be reported in the English literature. The diagnosis and treatment of this condition is discussed and the relevant literature is reviewed.

Computed tomography (CT) is the preferred method for evaluating the left periaortic infrarenal region. Structures larger than 11 mm in cross-sectional diameter in this region are considered abnormal and should be evaluated for lymphadenopathy, hydroureter, or a vascular abnormality such as venous thrombosis or varicoceles. Normal structures include inferior mesenteric vessels, left gonadal vein and artery, and ureter. The diagnostic process may be complicated by variations in anatomy, including double inferior vena cava, left inferior vena cava, retroaortic left renal vein, circumaortic left renal vein, horseshoe kidney, crossed-fused renal ectopia, renal agenesis, and ureteral duplication. Familiarity with the anatomy of this region and awareness of normal variants are necessary to avoid errors in diagnosis. Radiologists should also be aware of problems in CT technique (nonopacified bowel, dynamic and unenhanced scanning) that can confuse the diagnosis.

We present a case of a rare renal anomaly in which the 2 kidneys (separate or fused across the midline) are drained by a common renal pelvis and ureter. Previously reported cases have been reviewed and are classified in 3 groups according to their anatomical features. The lesion is associated with some frequency with imperforate anus, sacral and other vertebral defects, neurogenic bladder, vesicoureteral reflux, upper tract dilatation, and urinary tract infections.

Unusual mode of renal duplication may be confused with supernumerary kidney. The presented adult female complaining left flank pain had bilateral duplication of collecting system with ectopic opening in one of the left-sided ureter. Since the ureteral opening to the bladder neck resulted in giant hydronephrosis in the upper half segment responsible for her complaint, surgical resection was performed. The duplication of the left renal mass and collecting system was regarded as "unusual" in several points. First, the lower half segment of the left kidney looked a normal complete kidney, because it had upper, middle and lower calices. Second, the lower half segment was located rather superior to the upper one. Third, the parenchyma of the upper segment which was a rudimentary small mass of several grams was separated from the lower one. But the left renal artery was single, which supplied blood to not only the lower segment but also the upper one, and the two segments were connected tightly each other by loose areolar tissue. These facts prevented to categorize this case as supernumerary kidney. This case suggests that there may be many transitional cases between fused kidney and supernumerary kidney.

A case of fused pelvic kidney, in a 67-year-old woman is presented. The patient also had a bladder tumor that had invaded the bladder wall. The renal anomaly was confirmed by drip infusion pyelography, computed tomography scanning, (CT-scan) and angiography. The CT-scan showed lump kidney with an aplastic right kidney anterior to the sacrum. Two renal arteries derived from the right common iliac artery were demonstrated by pelvic-angiography. The right ureter was not identified during the total-cystectomy. The left ureter was fixed firmly to the surrounding tissues and its free portion was less than 7 cm long. Thus left ureterocutaneostomy was selected for the formation of the urinary diversion.

Multicystic renal dysplasia in a crossed fused or nonfused ectopic kidney is a rare occurrence that produces unusual imaging findings. In four such cases in neonates, three presented with a palpable abdominal mass and one was discovered in utero with maternal sonography. In three cases, sonography showed a multicystic mass, contiguous with the lower pole of the orthotopic kidney. In the fourth infant, a crossed, tiny dysplastic kidney was not visualized, but its markedly dilated ectopic ureter was seen traversing the spine on CT. Ureteropelvic junction obstruction was present in the three fused orthotopic kidneys. The characteristic imaging findings of multicystic dysplasia and crossed renal ectopia include a multicystic mass of variable size that is contiguous with the lower pole of a hydronephrotic, malrotated kidney; ureteral displacement and/or dilatation; and contralateral absence of the kidney and its renal artery.

A rare congenital malformation consisting of ectopic opening of the vas deferens into the fused segment of a refluxing triplicated ureter (trifid ureter) in an azoospermic man is described. Sperm were found in urine voided after ejaculation. Artificial insemination with sperm recovered from alkalinized urine resulted in pregnancy.
