[Keratotic pseudoepitheliomatous and micaceous balanitis]. / Balanitis pseudoepiteliomatosa queratósica y micacea.

OBJECTIVE: To describe the clinical and histopathological manifestations of a case of pseudoepitheliomatous, keratotic and micaceous balanitis and review the literature on this rare condition. METHODS: A case of pseudoepitheliomatous, keratotic and micaceous balanitis in a 63-year-old man is presented. The lesion appeared a few months after undergoing circumcision due to phimosis and recurrent inflammatory balanitis. RESULTS: The lesion relapsed after topical treatment with 5-FU, cryotherapy and shaving-biopsy plus electrocoagulation. It was finally diagnosed as epidermoid carcinoma and surgically excised. CONCLUSIONS: The clinical and histopathological features, course and relationship between micaceous balanitis and carcinoma of the penis are reviewed.

[Verrucous carcinoma of the penis: report of two cases]. / Carcinoma verrucoso de pene: a propósito de dos observaciones.

OBJECTIVES: Verrucous carcinoma, a variant of squamous cell carcinoma accounts for 5%-8% of all penile tumors. The unique histological features and behaviour of this tumor type prompted us to report these two cases.

[Lethality of prostatic origin]. / Letalidades de origen prostático.

We report a case of cutaneous metastasis originating from prostate adenocarcinoma. We underscore this rare site of metastasis and the poor outcome.

[Injection of autologous fatty tissue in the bladder submucosa: experimental study in swine]. / Inyección en la submucosa vesical de tejido graso autólogo: estudio experimental en suidos.

The results achieved by the use of inert materials via endoscopic injection for the treatment of urological pathologies have been disappointing. Furthermore, these materials are costly, carry the risk of migration and may not be tolerated locally. Autologous fatty tissue, however, is not costly and is tolerated better. The authors have conducted an experiment in the pig to evaluate the degree of resorption and persistence of autologous fat injected into the bladder submucosa. The results show that submucosal injection of autologous fat acts like an autograft and persists as mature fatty tissue. The degree of resorption and/or steatonecrosis is directly related to the amount injected; the smaller the amount used the better the results.

[High-flow priapism: diagnostic-therapeutic management]. / Priapismo de alto flujo: manejo diagnóstico-terapéutico.

We report a case of traumatic priapism with an evolution of three weeks at the time of the diagnosis. The foregoing condition had been caused by an arteriocavernal fistula. Several arteriograms and selective embolization of the compromised area were required for treatment. The etiological, pathophysiological and therapeutic aspects are discussed.

[Spontaneous disappearance of pulmonary metastasis secondary to renal cell carcinoma after nephrectomy. Presentation of a case and review of the literature]. / Desaparición espontánea de metástasis pulmonares secundarias a carcinoma de células renales tras la nefrectomía. Aportación de un caso y revisión de la literatura.

Spontaneous disappearance of pulmonary metastasis is an occasionally occurring phenomenon, thus reflected in the literature. The article presents one case of spontaneous disappearance of pulmonary metastasis of clear cells renal carcinoma, histologically confirmed by fine needle puncture aspiration. After 36 months of follow-up, the patient shows no evidence of recurrence.

[Cystic pyeloureteritis. Our approach]. / Pieloureteritis quística: nuestra actitud.

We report a case of massive cystic pyeloureteritis that had been diagnosed by ureterorenoscopy in a patient with recurrent urinary infection and episodes of nephritic colic. The reports published in the literature indicate there is no specific treatment for this disease whose etiology is unknown. Its pathogenesis has not been well-established and it is difficult to distinguish from other urothelial filling defects. Although it has also been reported that it may progress to malignancy, we believe that the therapeutic approach should be conservative.

[Endoscopic resection of tumor of the renal pelvis]. / Resección endoscópica de tumor de pelvis renal.

We report on a patient who was submitted to percutaneous resection of a solitary, low grade urothelial transitional cell tumor of the renal pelvis. A review of the literature shoned endourologic treatment to be a valid in carefully selected cases. The measures to minimize the risk of tumor spread and the good results obtained are discussed. However, a longer follow up and larger series are necessary in order to draw definitive conclusions.

[Eosinophilic cystitis associated with transitional cell carcinoma: apropos a case]. / Cistitis esosinófila asociada a carcinoma de células transicionales: a propósito de un caso.

An additional case of eosinophilic cystitis coexisting with transitional cell carcinoma of the bladder is presented. The patient was treated with antihistamine but posteriorly presented with an infiltrating tumor that warranted a cystectomy procedure and ureteroileostomy. The patient is currently symptom-free.

[Unique incision vasectomy: review of 1,800 cases]. / Vasectomía por única incisión: revisión de 1.800 casos.

We reviewed 1,800 vasectomy procedures using the double lateral scrotal incision and single incision of the raphe that had been performed at the Family Planning Center. The number of complications were minimal for both techniques: 6.5% for the patients submitted to the double incision and 5.5% for those submitted to the single incision procedure. The advantages of the single incision procedure are: it is easy to perform, less anesthesia is required, there are less complications, and the operating time is reduced.

[Percutaneous U-loop nephrostomy: our experience]. / Nefrostomía percutánea en raqueta: nuestra experiencia.

Thirteen U-loop nephrostomy procedures performed percutaneously in 9 patients are described. Thirty-three percent of these patients had a bilateral, one-stage procedure. This procedure can be performed under local anesthesia and, on average, requires 45 minutes. It is simple, yet it provides many other advantages; i.e., enhanced urinary drainage, easy to change and excellent patient tolerance. For all the foregoing reasons, we consider this procedure to be a valid alternative to open surgery.

[Renal embolism. Revascularization using conservative treatment]. / Embolismo renal. Revascularización con tratamiento conservador.

We report a case of embolism of the intrarenal arterial branches of a cardiac origin. The results of the urographic, ultrasound, ascending pyelography and laboratory work up prompted us to suspect the vascular nature of the condition. Its unilateral feature, involvement of the intrarenal arterial branches, and the coexisting mitral valve disease with atrial flutter advised conservative management with systemic anticoagulation.

[Inverted papilloma of the ureter]. / Papiloma invertido de uréter.

We report a case of inverted urothelial papilloma localized to the ureter in a patient with solitary kidney. Treatment was by segmental resection and end-to-end anastomosis. In spite of the benign nature of this tumor type and because treatment is conservative, patients should be closely followed owing to the possibility of recurrence and because progression to malignancy has been reported in the literature.

[Monoclonal gammopathy and osteolytic lesions as the initial manifestation of a metastatic hypernephroma]. / Gammapatía monoclonal y lesiones osteolíticas como primera manifestación de un hipernefroma metastásico.

We report on a patient with metastatic renal adenocarcinoma that had been detected following evaluation for monoclonal gammopathy associated with osteolytic lesions. When the foregoing associated conditions present, we must discard the presence of a myeloma. No objective data relating gammopathy with tumor behaviour are currently available.

[Bilateral adrenal masses during clinical staging of renal carcinoma]. / Masas adrenales bilaterales durante el estadiaje clínico del carcinoma renal.

We report a case of renal adenocarcinoma with bilateral adrenal masses at the time of diagnosis. Owing to the methods currently used for clinical staging, this association is no longer infrequently observed. Experience has demonstrated the value of the diagnostic techniques in this condition. The use of some of these techniques will depend on the findings during clinical staging of the tumor. Well-selected cases with metastasis to the adrenal gland can benefit from surgery.

[Primary abscess of the psoas muscle]. / Absceso primario de psoas.

An additional case of primary psoas abscess is described. The literature is reviewed and its etiopathogenesis, clinical features, diagnosis and treatment are discussed.

[Duplication of the inferior vena cava associated with renal carcinoma]. / Duplicidad de vena cava inferior asociada a carcinoma renal.

Although uncommon, vascular anomalies of the inferior vena cava can have important consequences in urological oncologic surgery. A case of duplicated vena cava associated with clear cell renal adenocarcinoma is described. This type of tumor of the genitourinary system had been detected intraoperatively.

[Treatment of urinary stress incontinence using paraurethral injection of autologous fat]. / Tratamiento de la incontinencia urinaria de esfuerzo mediante la inyección parauretral de grasa autóloga.

The authors present the late results (greater than 1 year) in the treatment of urinary incontinence in 15 women with stress urinary incontinence and 5 men with post-adenomectomy incontinence using endoscopic injection of autologous fat tissue obtained by microliposuction. Good results were achieved in 23% of the cases with stress urinary incontinence and in 0% of those with post-adenomectomy incontinence. Although the results are disappointing, they are not very different from those obtained with teflon injection. Furthermore, the technique is simple, has no complications and it costs very little to obtain the autologous graft material. A historical review of free fat grafting and injection of liposuction fatty tissue is performed and the hypotheses that have been put forward recently relative to the fate of the fat graft are discussed.

[Acquired hydrocele in the adult: sclerotherapy]. / Hidrocele adquirido del adulto: escleroterapia.

We report our experience in the treatment of hydrocele using sclerosant therapy in 50 patients with adult acquired hydrocele (AAH) or cord cyst (CC). The sclerosing agent utilized in all of the patients was quinacrine dihydrochloride (quinacrine) at a dose of 13.3 mg 50 cc aspirated volume. The results were assessed clinically, ultrasonographically and thermographically. The presence of multilocular cysts or incomplete aspiration of the liquid was the most frequent cause of failure. The results show a success rate of 85%; however, 18% required more than one treatment.

[Bladder bilharziasis: report of a case]. / Bilharziosis vesical: a propósito de un caso.

Herein we describe a case of vesical bilharziasis in a Spanish patient who became infected during a trip to an endemic area. The characteristic features of the disease and particularly its relationship to squamous type bladder tumors are discussed with a special focus on treatment with Praziquantel.
