Abnormal aorta and iliac arteries in children with urogenital abnormalities.

Retroiliac ureters have been found in association with a variety of urogenital abnormalities but the iliac artery usually retains a retroperitoneal position. We report 7 children with various urogenital abnormalities (cloacal malformation 4, bladder agenesis 1, urogenital sinus 1, neuropathic bladder 1) in whom the lower aorta and iliac arteries were so distorted as to pose a significant operative hazard. In all cases the distal aorta and/or iliac arteries lay within the peritoneal cavity, often anterior to the bladder. In 3 cases the aorta was fixed by a short ligament to the umbilicus, and in 3 patients one of the iliac arteries ran across the pelvis behind the pubic bones before entering the leg. In one patient an anomalous iliac artery was inadvertently divided during reconstruction of a cloaca; when recognized, the vessel was rejoined. Recognition of an association between urogenital or cloacal malformations and a major vascular anomaly is of great importance to reconstructive surgeons who, if not forewarned, could unintentionally compromise the arterial supply to one or both lower limbs.

[Traumatic pseudocyst of the lung].

A rare complication of closed chest injury is the traumatic pulmonary pseudocyst. A well documented case of a 15-year-old boy with this definite, acutely formed, primary structural manifestation within the lung is reported with a short review of nomenclature, pathogenesis, diagnosis and treatment.

Neourothelium in bladder augmentation. An experimental study in rats.

Experimental surgery in 7 rats was used to investigate the possibility of trigonal urothelium overgrowth into a segment of bowel which had its own mucosa removed. After subtotal cystectomy the intestinal mucosa from the cecum was completely stripped away, and the cecum was then anastomosed to the remainder of the bladder. Urothelial overgrowth of the bowel surface was evident one (3 animals) and two months (4 animals) after the initial procedure.

Granular cystitis in girls. Long-term follow-up.

Granular cystitis or 'papular cystitis' is a very common form of cystitis in young girls. In this paper we show the evolution of this affliction in women after puberty. In a series we were able to follow up leukoplakia or follicular cystitis patients to the age of 16 years.

Unilaterally impalpable testis.

Thirty children presenting with a unilateral impalpable testis and a normally descended contralateral testis underwent surgical exploration. The testis was absent ('vanishing testis') in 12 cases (40%) and orchidectomy for a dysgenetic testis was performed in a further 5 cases. The overall rate of monorchism following surgery was therefore 56%. It is desirable that parents be advised of this possibility pre-operatively.

Renal tumours other than Wilms' tumour in the paediatric age group.

The non-Wilms' renal tumours in the paediatric age group may be classified according to age of onset, clinical-biological behaviour and morphology. This distinction is of practical importance because treatment and prognosis are different from those of Wilms' tumours. We report on clinical features, histological patterns, treatment and outcome of 9 cases seen between 1959 and 1981: - renal cell carcinoma (3 patients) - congenital mesoblastic nephroma (2 patients) - bone metastasizing renal tumour (3 patients) - angioleiomyolipoma (1 patient) Our experience is compared with the few reports of the same conditions in the literature.

Extrinsic enteroureteroplasty: a piggyback technique for mid-ureteric replacement.

Replacement of the ureter was performed in 10 piglets using a serosa-lined intestinal tube. It was constructed by plication of the intestine and closing it at the antemesenteric border. The tube was then interposed to bridge a ureteral defect of variable length (4-6 cm). Information from IVU and macroscopic and microscopic results showed that the function of the interposed segments was achieved in all cases, however, with significant stenosis in the absence of adequate postoperative splinting in 5 cases, and neomucosa - similar to uroepithelium in the beginning and a complete urothelium after 3 months - covered the interpositioned tube.

[Double kidney with ureterocele].

Twenty-six children with ureteroceles--twenty-three with unilateral double collecting system and three with bilateral double kidney--are analyzed. The clinical and radiological features of these ureteroceles are presented. The different possibilities of surgical management and their results are discussed. In 14 of these children we performed resection of the ureterocele with en bloc reimplantation of both ureters. Eleven cases were treated by resection of the ureterocele and upper pole nephroureterectomy and four cases by nephroureterectomy. Vesicoureteral reflux in both renal pelvic moieties was found in five cases after ureteral reimplantation en bloc. Because of frequent bilateral disease (10%) and the common association of other urological malformation it is preferable to try to perform ureteric reimplantation rather than primary nephroureterectomy even when the possibility of postoperative reflux is considered.

[Development of small intestinal neomucosa].

Under certain conditions epithelium grows on the peritoneal surface. By folding the colon of the rat the authors constructed a seromuscular tunnel of which the two ends were sutured to the transsected ileum, making normal small bowel passage possible. 6-12 weeks after the operation a pouch was found on which a one-layer cylindric epithelium had developed showing evidence of disaccharidase activity. Clinically the model could be used to enlarge the mucosal surface of the remaining small bowel following extensive resection.

[Ultrasonographic antenatal detection of obstructed bladder (author's transl)].

The antenatal diagnosis of bladder obstruction may be possible by ultrasonography of the mother. We report herein four cases of prenatally detected megacystis: two were Prune Belly syndromes, one of which was aborted. The two others were female infants, one had a megacystis-microcolon-hypoperistalsis syndrome, in the other hypoperistalsis was present along with megacystis. Transuterine-transfetal bladder taps were used to relieve bladder pressure in utero.
