[Anterior sacral meningocele with urologic manifestations. Report of 3 cases].

Anterior sacral meningocele is defined as a spinal fluid-filled thecal sac in the pelvis communicating with the spinal subarachnoid space through a defect in the anterior sacral wall. Since scimitar shape of the sacrum is characteristic, diagnosis is easily confirmed by echography and myelography. The sac very often contains benign tumors and a thickened filum terminale which can achieve a tethered cord syndrome. This congenital malformation, whose autosomal inherited condition has been proposed, has usually few characteristic symptoms but can present itself as a neurogenic bladder from tethered cord origin. Neurosurgical treatment can prevent rupture of the meningocele with meningitis. In addition to symptomatic treatment of the neurogenic bladder, the urologist must advise neurosurgical operation to preserve potency and cure specific bladder dysfunction secondary to tethered cord syndrome.

[Major urological cancer excisions after the age of 75].

32 patients more than 75 years old had major surgical procedures for urologic neoplasms: radical nephrectomy for renal cell cancer (9 cases), nephroureterectomy for upper urinary tract tumor (3 cases), radical cystectomy for invasive bladder cancer (20 cases). Postoperative mortality was 12.5%. In the nephrectomy group, 3 palliative procedures gave a mean survival time of 7 months. On 9 curative procedures, 7 patients are alive and free of disease with a mean follow-up of 45.6 months. In the cystectomy group, 5 palliative procedures gave a mean survival time of 7 months. On 15 curative procedures, 6 patients are alive and free of disease with a mean follow-up of 18.6 months. Our data confirm that curative procedures can be performed in the elderly. Mean survival time and quality of life after palliative procedures suggest that only true comfort procedures have to be performed.

[Resection of pyelo-ureteral junction without external urinary drainage for primary ureteral stenosis].

During a 3-year period 30 consecutive patients (20 women and 10 men) with primary ureteropelvic junction obstruction underwent open dismembered pyeloplasty associated with the placement of an indwelling double pigtail stent via antegrade approach. Renal stones were removed in 8 cases, multiple nephrotomies being necessary in 2 patients. 2 men had temporary urinary leakage. Mean hospitalization time after surgical procedure was 9,8 days, but last 18 patients were discharged after only 7,3 days, Stents were removed 4 to 5 weeks after operation. With 1 to 4 years post-operative follow-up, successful treatment with relief of obstruction was achieved in all 38 patients without secondary stricture. Open pyeloplasty with double pigtail stenting appears to be a safe and successful procedure for the treatment of primary ureteropelvic junction obstruction in adults. Comparison with percutaneous endopyelotomy in terms of morbidity, duration of hospitalization and success rate appears to be in favor of open procedure, although secondary stricture may require endourological procedure.

[Emphysematous pyelonephritis].

The authors report on a case of a emphysematous pyelonephritis due to Klebsiella pneumoniae, occurring in a diabetic patient and successfully treated by nephrectomy. They compare it to the literature.

Renal transplantation and Kock pouch: a case report.

We report on a young woman with anuric, terminal renal insufficiency whose bladder could not be used for renal transplantation. A Kock pouch was implanted during stage 1 of treatment and the capacity of the pouch was increased artificially with physiological saline solution. The patient subsequently underwent renal transplantation. Results were excellent with regard to continence and ease of catheterization. No complications due to infection were observed despite immunosuppression and electrolyte disorders were minor.

[Treatment of lithiasis in horse-shoe kidney].

Between september 1985 and april 1987 the authors treated 16 patients with 27 calculi in horse-shoe kidneys. 14 patients were treated by extra-corporeal lithotrity with two failures from the outset because of impossibility of positioning the lithiasis at the second site of the ellipsoid. In the other twelve cases and 3 months after treatment there were four complete successes (no residual calculi) and eight partial successes with, in seven cases, residual calculi less than 4 mm in diameter and, in one case, a residual calculus of more than 10 mm. Of 4 percutaneous nephrolithotomies, including two from the outset, there were no post-operative complications and, only in one case, residual fragments in the inferior calyx. The authors then analyzed the special features and difficulties inherent to the unusual topography of the renal cavities of horse-shoe kidneys. Such topography leads to modifications which are described by the authors both in the technique of extra-corporeal lithotrity as well as in that of percutaneous nephrolithotomy. The study ends with an analysis of the respective indications of the two methods of extra-corporeal or endo-urological treatment of lithiasis affecting horse-shoe kidneys.
