[Long-term results of interferential current stimulation in the treatment of bladder instability]. / Résultats à long-terme de la stimulation par courants interférentiels dans le traitement de l'instabilité vésicale.

OBJECTIVE: To study the late results of interferential current stimulation in the treatment of detrusor instability. MATERIAL AND METHODS: 62 patients with detrusor instability refractory to medical treatment by anticholinergic drugs were treated by interferential current stimulation. This technique combines the advantages of retraining stimulation with external application. This retrospective study was based on 62 patients (43 children, 11 men and 8 women) presenting with detrusor instability between January 1990 and December 1997. All patients were assessed clinically and by a radiological, bacteriological and urodynamic work-up prior to treatment. The mean follow-up was 5 years (range: 18 months to 10 years). RESULTS: The results of this technique were excellent, with 80.9% of cures at one year, but they tended to fade over time to 40% of cures at 5 years. However, results which deteriorate after one year can generally be maintained by performing 5 maintenance sessions every 12 or 18 months. CONCLUSION: Treatment of detrusor instability by interferential current is a reliable technique which constitutes an alternative to the other methods of retraining stimulation and can be performed in cases of instability refractory to anticholinergic drugs, before considering neuromodulation or surgery. Five to 10 maintenance sessions every 12 or 18 months ensure stable long-term results in the majority of cases.

[Treatment of bladder instability with interferential current. Report of 20 cases: preliminary results]. / Traitement de l'instabilité vésicale par courants interférentiel. A propos de 20 cas: résultats préliminaries.

20 patients with unstable bladder unresponsive to medical treatment by anticholinergics were treated by interferential current retraining stimulations. This technique combines the advantages of retraining stimulation with external application. Each patient received 6 to 20 stimulation sessions at a rate of one per week in children and two per week in adults. 18 patients were clinically and urodynamically improved with resolution of incontinence and the follow up urodynamic assessment showed return of normal bladder volume and tone. No adverse effects were observed. No recurrences of the symptoms were observed with a mean follow-up of 18 months. The authors believe that this reliable technique constitutes an alternative to other retraining stimulation methods.

[Percutaneous renal surgery apart from calculi. Current possibilities and limitations]. / La chirurgie rénale percutanée en dehors de la lithiase. Possibilités et limites actuelles.

The purpose of this study is to describe the technical modalities and to evaluate the results of percutaneous renal surgery for ureteropelvic stenosis, pyelocaliceal diverticula, renal cysts and urothelial tumors of the kidney. Based on a review of literature and although the number of the reported cases is limited, the results indicate a great deal of variability in the success of these technics depending on the pathology.

[Therapeutic possibilities in pyelocaliceal diverticula]. / Possibilités thérapeutiques des diverticules pyélocaliciels.

Pyelocaliceal diverticula sometimes give rise to complications such as lithiasis or infection requiring surgical treatment. In addition to various open surgical techniques there is the possibility of percutaneous surgery. This short series of nine cases collected in 2 years covers a complete review of the different therapeutic possibilities.
