[Sling technique with suprapubic punction: report of a complex case with recurrent urinary incontinence]. / Técnica de cabestrillo por punción suprapúbica: a propósito de un caso complejo de incontinencia urinaria recurrente.

A difficult case described herein was successfully treated using a sling procedure that is safe and easy to perform. It combines the simplicity of the endoscopic techniques and the advantages afforded by the materials used. This simple yet effective technique is particularly useful in patients at high surgical risk, with afunctional urethra in whom operative maneuvers are performed with difficulty, with previous unsuccessful surgery, including the Stamey procedure, with urethra and bladder in the normal positions and a neurogenic component.

[Leydig cell tumor associated with gynecomastia]. / Tumor de células de Leydig con ginecomastia.

We report a case of interstitial cell or Leydig cell tumor, an uncommon tumor type, that presented with evident feminizing features and acute testicular inflammatory process which warranted hospitalization. The literature is reviewed highlighting the most important aspects of this condition.

[Carcinoma and renal schistosomiasis]. / Carcinoma y esquistosomiasis renal.

A case of a patient with renal schistosomiasis and clear cell renal carcinoma involving the same organ is reported herein. To our knowledge, the foregoing association has not been reported in the literature.

[Anatomic effects of Stamey's urethrocystopexy as modified by Orozco and Perez Poo]. / La repercusión anatómica de la uretrocistopexia de Stamey modificada por Orozco y Pérez Poo.

The results of the Stamey endoscopic cervicopexy modified procedure (Orozco-Pérez Poo) performed in 20 incontinent female patients are analyzed relative to urethrovesical prolapse, length of urethra, position and mobility of the vesical neck and base, diameter of the proximal urethra, and the configuration of the vesicoureteric junction, including the posterior angle. It is concluded that no significant difference exists between the results reported by Stamey and co-workers and those achieved by the authors. The modified procedure permits optimal re-placement of the vesical neck, lengthening and fixation of the urethra; thus, measuring the length of the urethra can be useful in the postoperative evaluation of the qualitative results afforded by this procedure.

[Wunderlich syndrome as manifestation of leiomyosarcoma of the kidney]. / Síndrome de Wunderlich como manifestación de leiomiosarcoma renal.

We report on a case of renal leiomyosarcoma whose presenting features were those of spontaneous perirenal hemorrhage (Wunderlich's syndrome). The low incidence of this disease entity, its severity and uncommon form of presentation which did not permit correct preoperative diagnosis of the underlying disorder have prompted us to report the present case.

[Treatment of ureteral lithiasis with ureteroscopy]. / Tratamiento de la litiasis ureteral por ureteroscopia.

We describe our experience and the results achieved in the treatment of ureteral lithiasis by ureterorenoscopy. Our results show the usefulness of this technique for calculi in the lower ureter. Furthermore, it can be used in combination with ESWL and PCN. Calculi in the lumbar ureter can be pushed up into the kidney for subsequent treatment with ESWL or PCN. We analyzed the results of 133 URS procedures that had been performed to treat calculi in the ureter. URS was used in combination with ESWL in 20 patients. Analysis of the success, failures, and complications of URS demonstrate the usefulness and efficacy of this procedure in the treatment of urinary calculi. Complications can be resolved with no life-threatening risks. The number of complications will decrease with our increasing expertise in the use of this technique.

[Multilocular cyst of the kidney]. / Quiste multilocular del riñón.

We report on a case that met all the diagnostic criteria for multilocular renal cyst. Treatment was by conservative surgery. The literature is reviewed and the therapeutic approach advocated for this condition is discussed.

[Multicentric oncocytoma of the kidney: presentation of a case]. / Oncocitoma renal multicéntrico: presentación de un caso.

We report on a 62-year-old female patient who consulted for G.I. tract disorders and was diagnosed as having renal oncocytoma. The rarity of this disease entity prompted us to report on this case, highlighting the malignant course of this tumor type despite its apparently benign features.

[Ureterorenoscopy combined with extracorporeal shockwave lithotripsy]. / Ureterorrenoscopia asociada a litotricia extracorpórea por ondas de choque.

In May 1986, extracorporeal shock wave lithotripsy and endourologic procedures became available in the treatment of lithiasis at the "Hermanos Ameijeiras" Hospital. The present study describes our experience and the results achieved during a 12-month period using endourologic procedures. During this period 65 URS procedures were performed to treat post-ESWL ureteral obstruction, and 22 to push the stone up to the kidney for subsequent ESWL treatment.
