[Endourologic complication: endourologic resolution]. / Complicación endourológica: resolución endourológica.

OBJECTIVES: To report an uncommon endourological complication that was also resolved by endourological methods. METHODS/RESULTS: We report on a patient with a right solitary kidney, radiolucent renal stone and an indwelling double-J catheter. While removing the double-J catheter after ESWL, it broke at the level of its distal third. The proximal two thirds remaining in the ureter were successfully removed by ureteroscopy after several attempts by ureteroscopy and percutaneous nephroscopy. CONCLUSIONS: Except for special circumstances, most of the endourological complications can be resolved by an endourological procedure.

[Extracorporeal shock wave lithotripsy (ESWL) in children: our experience in 1995]. / Litotricia extracorpórea por ondas de choque (ESWL) en niños: nuestra experiencia en 1.995.

OBJECTIVES: The present study reviews our experience and analyzes the results achieved with extracorporeal shock wave lithotripsy in the treatment of urinary calculi in children. METHODS: From 1985 to 1995, 36 children, with ages ranging from 5 months to 14 years, were treated by ESWL, and in some cases by combination therapy (percutaneous nepholithectomy and/or ureteroscopy). RESULTS: Excellent results were achieved in 74.9% of the patients; of these, 52.7% were stone-free 2 to 90 days after treatment. CONCLUSIONS: Extracorporeal shock wave lithotripsy is the treatment of choice in children with urinary lithiasis, although there are some exceptions. The method of evaluation and treatment in children are the same as in the adult patients.

[Memotherm as a therapeutic device in infravesical obstruction]. / El Memotherm como medio terapéutico de la obstrucción infravesical.

OBJECTIVE: To determine the efficacy of the intraurethral mesh in the treatment of infravesical obstruction in patients at high surgical risk unamenable to other treatment modalities. METHODS: We evaluated 13 patients with obstruction and at high risk for conventional surgery (TURP) who underwent insertion of the Memotherm intraurethral prosthesis. RESULTS: The procedure was performed rapidly with scant morbidity and the patients were discharged from the hospital early. Improvement, evaluated by the IPSS-L, was referred by 84.6% of the patients at 45 weeks follow up. Post-treatment improvement was evidenced by the absence of postvoiding residual urine at ultrasound in 69.2% of the patients and improved flowmetry in 84.6% of the patients. The early post-treatment complications included hematuria with irritative symptoms (80% of the patients). The mesh prosthesis had migrated in 15%, but could be repositioned. No case required removal of the prosthesis. CONCLUSIONS: This method affords a rapid and atraumatic solution for obstructed patients at high surgical risk. The material (heat sensitive nitinol) and the design of the mesh facilitate repositioning in the few cases in whom this had been required.

[Technics of ureteral endoscopic access]. / Técnicas de acceso endoscópico ureteral.

OBJECTIVES: The present article briefly reviews the history of endoscopic access to the ureter, since visualization of the ureter was first attempted until the procedure was developed by Pérez-Castro in 1979. METHODS/RESULTS: The development of the rigid ureteroscopes, the difficulties arising from the anatomical structures during endoscopy that require ureteral dilatation, the anatomy of the juxtavesical segment of the ureter and the pathologies that may alter it, and the present and future indications of ureteral dilatation are discussed. Patient preoperative evaluation is briefly described and one of the techniques of ureteral dilatation is analyzed. Finally, a brief summary comparing the different techniques is given. CONCLUSIONS: The technique of choice for ureteral dilatation must be simple, easy to perform, low-cost and one which reduces the iatrogenic lesions and shortens the duration of hospital stay.

[Priapism: analysis and results of surgical treatment in 9 cases]. / Priapismo: análisis y resultados del tratamiento quirúrgico en nueve casos.

A review is made of nine cases of priapism, seven of which were idiopathic and two secondary. The different etiological and clinical aspects are analyzed. All the patients underwent surgical treatment, with 42.8% of good, long-term results and the authors always recommend aggressive and early, surgical treatment.
