[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.

[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.

[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.

[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.

[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.

[Endoureteropyelotomy in impassable stenosis of the pyeloureteral junction: instrumental conversion of the stenosis into an intrapelvic ureterocele]. / Endoureteropielotomia en estenosis de la unión pieloureteral infranqueable: conversión instrumental de la estenosis en uretrocele intrapiélico.

The authors describe a new endourological procedure for resolving cases of stenosis of the impassable ureteropyelic union. The procedure consists in raising the pyeloureteral union by means of a Chevassu's catheter equipped with its wire guide, introduced backwards into the ureter and which, when pushed externally, situates the ureteropyelic union by way of intrapyelic ureterocele. We then proceed to the lengthwise cutting of this ureterocele under nephroscopic view until the ureteral catheter is exposed. With this procedure a successful solution is provided for those cases that were debarred from endourological surgery because the tutor catheter was unable to pass.

[Endoscopic injection of autologous adipose tissue in the treatment of female incontinence]. / Inyección endoscópica de tejido graso autólogo en el tratamiento de la incontinencia femenina.

We describe a new procedure utilizing autologous fat instead of teflon injection in the treatment of female urinary incontinence that is equally useful in correcting postadenomectomy incontinence in the male and vesicoureteral reflux. We have used this new procedure over the past 4 months in 10 patients with urinary stress incontinence and no concomitant cystocele. The procedure is performed under spinal anesthesia. Small cylinders of subcutaneous abdominal fatty tissue are obtained by microliposuction. The fat graft in the form of four 10 ml. wheals is then injected in the vesical neck. We emphasize that this technique is simple and there are no complications. The low cost of this technique requiring a 24 h stay at the hospital affords additional advantages. Likewise, the procedure can be repeated or subsequent surgical procedures can be performed without difficulty in the event correction is unachieved.
