In an one year old asymptomatic girl with a slight levoposition of the heart on chest X-ray and mild right ventricular hypertrophy in the ECG further cardiological investigation disclosed several anomalies: Absence of the left pulmonary artery, collateral vessels to the left lung both from the abdominal aorta and from a left brachiocephalic trunc, hypoplasia of the left lung, right sided aortic arch. There was no malformation of the heart itself. This is supposed to be the first reported case, in which the aforementioned anomalies were associated with hypoplasia and hydronephrosis of the left kidney and stenosis of the ostium on the left ureter. Considering the normal and pathologic development of the human embryo it may be assumed, that there is no immediate relationship between the malformation of the left lung and its vessels on one hand and the defects of the left kidney and ureter on the other hand. The hypothesis is put forward, that the damage of the embryo occurred limited to one side during the period of teratogenetic determination common to both of the organ systems involved.

The first reported case of an enlarged right spermatic vein with an atypical course causing hydronephrosis and hydroureter in a twenty-eight-year-old man is presented. Transection of the obstructing spermatic vein improved the hydronephrosis. Causes, symptoms, and treatment of obstruction of the ureter by enlarged gonadal veins are discussed. The similarities between the "ovarian vein syndrome" in the female and this case are pointed out.

The chronic encapsulated extravasation of urine, most accurately designated as uriniferous perirenal pseudocyst, causes urine to collect within a characteristic complex of radiographic findings including an elliptical soft-tissue mass in the cone of renal fascia. This results in the flank oriented inferomedially with upward and lateral displacement of the lower renal pole, medial displacement of the ureter, obstructive hydronephrosis, and perhaps evidence of extravasation into the mass. Since the clinical recognition of the mass is typically delayed several weeks following the original traumatic episode, prompt radiological diagnosis is essential before irreparable damage to the kidney occurs.

Close phenotypic similarity between two cases carrying a rec(3) dup q,inv(3) (p25q21), 12 additional infants from the same inv (3)(p25q21) kindred who lived less than 1 year, and eight cases studied in other medical centers has led us to postulate the existence of a distinct chromosome 3 duplication-deletion syndrome. In the presence of trisomy for (3)q21 leads to qter and monosomy for (3)p25 leads to pter, the facial dysmorphy is unique: a distorted head shape due to irregular cranial sutures, thick low eyebrows, long eyelashes, persistent lanugo, distended veins on the scalp, hypertelorism, oblique palpebral fissures, a very short nose with a broad depressed bridge and anteverted nares, protruding maxilla, thin upper lip, micrognathia, low-set ears, and a short webbed neck. Port-wine stains, congenital glaucoma, cloudy corneas, cleft palate and harelip also occur frequently. Each infant has difficulty sucking and swallowing. Congenital anomalies of the cardiovascular system, of midgut rotation, and of the urogenital system are noted for the infants who died neonatally. Most frequent is a ventricular septal defect, followed by atrial septal defect, patent ductus arteriosus, patent foramen ovale, and coarctation of the aorta. Omphalocele, umbilical hernia, hyperplastic kidneys, polycystic kidneys, double ureter, hydro-ureter, hydronephrosis, and undescended testes often occur. The extremities are short in proportion to the length of the trunk. Clinodactyly, coxa valga, talipes, and spina bifida are frequently observed.

The occurrence of non-function in one half of a horseshoe kidney resulting from hydronephrosis can, if unrecognized, create a serious surgical as well as medical problem. The anterior position of the ureter in relation to the isthmus, as well as strictures and accessory vessels increase the incidence of hydronephrosis, which if severe enough, can go on to non-function. The key diagnostic factor is the observation of the visualised side, which shows the characteristic malrotation of the calyces and the deviation of the long axis of the kidneys; these are associated with a mass effect on the obstructed side, with or without a 'crescent' sign. Five cases of this unusual occurrence are presented.

1. Thirty-two per cent of cases examined by I.V.P. showed evidence of disease (20 per cent hydronephrosis, 12 per cent chronic pyelonephritis). 2. The incidence of V.U. reflux on micturating cysto-urethrography was 13 per cent. V.U. reflux is associated with chronic pyelonephritis in a high proportion of cases as would be expected. A normal pyelogram does not exclude V.U. reflux as mentioned by Cobb (1966). 3. Patients with complete paralysis show a significantly high incidence of chronic pyelonephritis, hydronephritis and V.U. reflux. 4. In case of unilateral hydronephrosis and chronic pyelonephritis there is a striking predilection for involvement of the right kidney. The cause for this is not evident but possibly the fact that the right ureter is shorter than the left is a factor.

A case is presented in which extreme hydronephrosis simulated absence of the right kidney. The hydronephrosis occurred as a result of surgical ligation of the right ureter 10 years previously. There was no visualization of the excretory system by intravenous urography or retrograde pyelography. Abdominal aortography did not show the renal artery. Selective renal venography revealed a patent venous bed with splaying and thinning of the intrarenal veins. The contribution of renal venography is discussed in clarifying cases in which the kidney and the renal artery were not visualized.

By ligation of the ureter, causing partial ureteral stenosis, unilateral hydronephrosis was induced in 10 dogs. Renal function studies including creatine clearance and osmolality determination were performed both before and after the ureteral ligation. The renal function analysis after induction of hydronephrosis included pyelovenous and pyelolymphatic reflux studies, with deposition of dextran in the renal pelvis at different intrapelvic pressures. Analysis with respect to sodium, potassium, chloride and dextran in the thoracic duct lymph, peripheral blood and urine from the intact kidney were performed. The results show a reduction of the renal function in hydronephrosis, little transport of dextran via the lymph and blood, and no significant increase in the lymphatic transport of the studied ions on elevation of the intrapelvic pressure.

It is reported on a septennial observation of a 43 year old woman, who was admitted to the hospital in 1968 with at first unclear symptoms and who developed an azotemia within a few days. The infusion pyelogram showed a hydronephrosis with enlargement of the upper part of the ureter; the lower part of the ureter was normal. After displacement of the ureters out of the fibrotic clasping into a duplicate of the peritoneum, the urine flow has normalized. After 7 years the patient is now healthy and able to work. The cause of the urinary stasis was histologically cleared as retroperitoneal fibrosis.

A case of the rare combination of horseshoe kidney, bilateral duplication of the pelvis and ureter, with stricture of one uretero-pelvic junction causing symptomatic hydronephrosis is reported. The patient was treated with resection as modum Anderson-Hynes. The embryology, symptomatology and treatment of such anomalies is discussed.
