[Self-expanding metallic endoprosthesis in the treatment of recurrent ureteral stenosis]. / Endoprótesis metálicas autoexpandibles en el tratamiento de las estenosis ureterales recidivantes.

OBJECTIVE: To describe two cases of recurrent fibrotic stricture of the uretero-vesical junction treated with a metallic self-expanding endoprosthesis which has successfully achieved patency of the stenotic area in the medium-term. METHODS: Two cases of difficult ureteral stricture are described. Both cases presented obstruction of the terminal ureter by abundant fibrotic tissue in the bladder wall following radical prostatectomy in one case and TUR in the other for non-infiltrating bladder carcinoma. Several attempts to recover patency by endoscopic resection and placement of a double-J stent in these patients had previously failed. The patients were therefore submitted to resection of the fibrotic area and insertion of a self-expanding endoprosthesis (Wallstent), which was eventually enclosed by fibrous tissue at its vesical portion. Both cases underwent resection again and another endoprosthesis (Memotherm) was inserted to extend the previous prosthesis 1 cm within the bladder lumen. RESULTS/CONCLUSIONS: When the endoprosthesis is placed in the uretero-vesical junction with its tip flush with the bladder wall, it is eventually enclosed by fibrous tissue, which invariably leads to recurrent obstruction. We have found that extending the prosthesis 1 cm within the bladder lumen can overcome the foregoing complication, although the long-term results have as yet to be established.

[Nesbit's cavernoplasty in the treatment of congenital curvature of the penis. Our own cases]. / Cavernoplastia de Nesbit en el tratamiento de la incurvación congénita de pene. Nuestra casuística.

OBJECTIVES: The present study was conducted to evaluate the results of Nesbit cavernoplasty in the treatment of congenital penile curvature without hypospadias and the sexual performance in relation with the minimum subsequent shortening of the penis and the discomfort caused by the cavernous scar. METHODS: 21 patients were followed by means of case history and consultations. This was completed with a questionnaire and, in some cases, long-term postoperative photographs taken by the patients of their erections. RESULTS: No complications were observed. Good cosmetic results were achieved in all cases and both erection and sexual performance were completely satisfactory. CONCLUSIONS: Nesbit cavernoplasty is a completely satisfactory technique for the correction of congenital penile curvature without hypospadias. The results obtained show that all the objectives pursued are achieved and, moreover, that the patient feels cured and completely satisfied with the results.

[Urothelial carcinoma of the ureter excised using percutaneous nephrostomy]. / Carcinoma urotelial ureteral resecado por nefrostomía percutánea.

We report on a case of ureteral carcinoma submitted to resection by percutaneous nephrostomy. After considering the different therapeutic alternatives, we believe that the approach described herein is very interesting in well-selected cases since it is a highly conservative surgical procedure that permits followup and reoperations relatively easily.
