21/237. Clinics in diagnostic imaging (67). Hydronephrotic horseshoe kidneys with multiple calculi.

    Horseshoe kidney is the commonest congenital renal anomaly. Its inherently-poor drainage system renders the patient prone to stone formation. A 56-year-old man with bilateral renal stones in a horseshoe system associated with hydronephrosis is presented. He was treated successfully with bilateral CT-guided percutaneous nephrostomy and percutaneous nephrolithotripsy. Various treatment options, including ESWL, PCNL and open surgery, are discussed.

22/237. Uriniferous perirenal pseudocyst: new observations.

    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.

23/237. Unusual presentation of cecoureterocele.

    A three-year-old female had a nephroureterectomy for a hydronephrotic left kidney with a total duplicated collecting system. Postoperatively urinary retention developed which was found to be secondary to a previously nonobstructive cecoureterocele. A brief review of cecoureteroceles is given along with the possible cause of this unusual presentation.

24/237. Further clinical and sensorial delineation of Schinzel-Giedion syndrome: report of two cases.

    Schinzel-Giedion syndrome is a rare multiple congenital malformation syndrome defined by an evocative midfacial retraction, kidney and urinary malformations and multiple skeletal abnormalities associated to a recently described neurodegenerative process. Two children with SGS are reported with identical clinical findings: megacalycosis, progressive neurodegeneration with infantile spasms and hypsarrhymtic activity. Ocular investigations revealed alacrimia and corneal hypoesthesia. Computed tomography of the temporal bone showed a tuning-fork malformation of the stapes for both children. These features may contribute to further delineation of SGS as additional clinical criteria.

25/237. Massive unilateral non-functioning hydronephrosis in horseshoe kidney.

    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.

26/237. Transosseous access for decompression of an obstructed pelvic kidney.

    We report a case of an obstructed pelvic kidney which was decompressed using a transosseous access route. The patient presented with obstructive uropathy and fever, necessitating decompression. Initial access was gained to the kidney by traversing the ilium, allowing subsequent retrograde placement of a double-J ureteric catheter.

27/237. Selective renal venography in the evaluation of a non-functioning hydronephrotic kidney.

    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.

28/237. pyonephrosis due to salmonella cholerae-suis variant kunzendorf.

    A patient with unilateral infection of the kidney due to Salm. cholerase-suis is presented. Long-term treatment with ampicillin was of no avail. nephrectomy terminated the infection. The extirpated kidney showed severe obstruction, stones and tissue damage.

29/237. Sigmoid kidney associated with renal adenocarcinoma.

    A rare case of adenocarcinoma in a sigmoid kidney is reported. The literature is reviewed and the operative technique described. Preoperative arteriogram and cavogram are an essential part of the evaluation and provide aid in the surgical approach.

30/237. Fetal urinoma as a sign of a dysplastic kidney.

    We describe a female neonate in whom a urinoma was first diagnosed at 20 weeks of gestation without any evidence of underlying urinary tract obstruction. The urinoma became apparent following the performance of a "bloody tap" amniocentesis. Sequential ultrasonography, both fetal and up to 3 months after birth, showed eventual resorption of the urinoma in parallel with the development of a shrunken, non-functioning kidney. Except for the onset of high-renin hypertension, which spontaneously remitted at 1 year of age, the baby's postnatal course was uneventful. Renal function was normal. The presence of a fetal urinoma as a sign of a dysplastic kidney is discussed.
