Duplication of the kidney: a potential diagnostic pitfall.

Nine patients with marked vesicoureteral reflux into a contracted, pyelonephritic kidney were found at time of surgery to have complete duplication of the affected side. Eight of them also had an ectopic ureterocele. The radiological diagnosis of duplication was virtually impossible as all these kidneys showed reflux nephropathy and were smaller than the contralateral kidney. The surgical management is briefly outlined.

Scaphoid megalourethra: a report of 2 cases.

Two cases of scaphoid type megalourethra are reported. Both patients had upper urinary tract dilatation and in one of them massive vesicoureteric reflux was demonstrated. The urinary tract in one patient returned to normal after correction of the megalourethra. The second infant, who had vesicoureteric reflux underwent ureteric reimplantation as well as correction of the deformed urethra. A description of the surgical technique and clinical and radiological follow-up is given.

Factor XI deficiency: detection and management during urological surgery.

Hereditary factor XI deficiency may remain undiagnosed until severe bleeding is observed after an operation or trauma. Two such cases were encountered and, therefore, a regular screening test for coagulation disorders among urological patients was initiated. During 2 years (1975 and 1976) 10 additional cases of factor XI deficiency were detected: 5 severe and 5 partial. All patients were Ashkenazic Jews of Eastern European origin. The 5 patients with severe factor XI deficiency underwent an operation without any complications. They were transfused with 5 to 20 ml./kg./day of fresh frozen plasma from the day before the operation until 10 to 14 days postoperatively. Of the 5 patients with partial XI deficiency 4 underwent an operation. In 1 of 3 patients who did not receive transfusions postoperative bleeding was observed. A minimal level of 0.3 U./ml. (30 per cent) factor XI was found necessary to ensure good hemostasis during and after an operation. In view of a recent finding of relatively high gene frequency of factor XI deficiency in Ashkenazic Jews it seems warranted to do a partial thromboplastin time in such patients who need an operation.

A unique combination of congenital genitourinary anomalies in a child.

A case of solitary crossed renal ectopia with concomitant, severe vesicoureteral reflux and a rudimentary ipsilateral ectopic ureter draining into the vas deferens is presented. In addition to these anomalies the patient had complete urethral duplication and right cryptorchidism, as well as right congenital dislocation of the hip. To our knowledge this is the first such case to be documented in the medical literature.

Surgical correction of vesicoureteral reflux in children with neurogenic bladder.

The reported success rate for correction of vesicoureteral reflux in the neurogenic bladder has been low. Reflux was corrected in 33 of 37 ureters in 23 selected children with neurogenic bladder-treated by reimplantation. Selection was based on good bladder capacity, little or no trabeculation and the expectation that the bladder would be useful in future management of the patient. Preoperative preparation and surgical technique are emphasized.

The management of urologic complications after kidney transplantation.

Urologic complications occurred in four (20%) of 20 kidney transplants performed in 18 patients. The complications encountered were acute hemorrhage from the distal end of the ureter, a calyceal fistula, a ureteral stricture with associated fungus infection, and obstructive uropathy. In two of the four cases it was necessary to sacrifice the transplant.
