[Pelvic lipomatosis: contribution of a new case to the literature].

OBJECTIVE: To describe an additional case of pelvic lipomatosis, a rare condition that can be encountered by the urologist. METHODS/RESULTS: A 66-year-old patient consulted for irritative voiding syndrome and fever. Patient evaluation by IVP and CT demonstrated pelvic lipomatosis. CONCLUSIONS: Pelvic lipomatosis is a disease with variable clinical and radiological features. Careful follow-up is warranted for prevention and treatment of possible complications.

[Socioeconomic justification of kidney transplantation].

OBJECTIVES: In recent years, the socioeconomic aspects of renal transplantation have focused the attention of the managers of the health care system and the professionals involved in transplant programs. The present study analyzed, within the context of renal transplantation, the two fundamental concepts of health care: quality of life and health costs. METHODS: A survey was conducted in 427 patients who underwent renal transplantation to evaluate the improvement in their quality of life. RESULTS: 93% referred physical improvement, 85% emotional, and 85% subjective improvement in their family relationship. Considering 9% of the kidneys were not viable, 15% of the grafts were lost in the first year and 4% thereafter, the cost of transplantation for the first year (in million pesetas) was 3,597 versus 2,961 for hemodialysis and 905 for the second year, with hemodialysis costs practically unchanged. CONCLUSIONS: Renal transplantation not only increases survival but also improves quality of life. It is less costly and the savings in health costs can be allocated to other fields of health care.

[Inverted Y ureteral duplication].

We report a case of inverted Y duplication of the ureter, incidentally found in a man consulting for hematuria. The diagnostic and therapeutic aspects are briefly discussed.

[Calcified renal oncocytoma].

The appearance of calcifications in a renal oncocytoma is uncommon since they appear in a scanty proportion of solid renal tumors. Nine cases of renal calcified oncocytomas have been previously reported; three of these had microscopic calcic deposits. The calcifications can be either central or peripheric. Their size or localization in the tumor mass does not alter the good prognosis of this type of renal tumor. We report on a 40-year-old man who presented a solid renal mass with central and peripheral linear calcifications. The histological analysis following nephrectomy disclosed a renal oncocytoma.

[Fraley's syndrome: a case report].

A case of Fraley's syndrome is described. Intermittent nephralgia was the presenting symptom. The diagnosis was made on the radiologic finding of obstruction of the infundibulum arising from vascular compression. The diagnostic and therapeutic aspects of this uncommon cause of obstruction of the infundibulum are discussed.

[Exceptional tumor: primary renal osteosarcoma. Review of 18 cases and report of a new one].

Primary renal osteosarcoma is an uncommon tumor type. To our knowledge, only 18 such cases have been reported to date. This tumor is very aggressive and may be localized or distant, the survival rate being less than 18 months despite a radical surgical procedure. Polichemotherapy has been attempted. We report on a 47-year-old patient with primary osteosarcoma of the right kidney, 8 cm x 8 cm in diameter, which was not amenable to surgical excision due to invasion of the adjacent structures. Systemic polichemotherapy was unsuccessful, and the patient died 3 months following diagnosis with multiple pulmonary metastases.

[Rectal involvement secondary to prostatic adenocarcinoma].

Rectal involvement secondary to adenocarcinoma of the prostate is uncommon and carries a poor prognosis. Distinguishing secondary from primary rectal tumors is mandatory, since each condition warrants a completely different treatment. There are at least five forms of clinicopathological involvement, depending on the rectal wall invasion and its consequences. We report on 6 cases, 4 had been diagnosed when rectal invasion was present, the enteric involvement appeared during the process in 1 patients and the other had prostate carcinoma coexisting with squamous cell carcinoma of the anus.

[Fournier's gangrene. Presentation of 11 cases and review of the literature].

Fournier's gangrene is an infectious necrotizing cellulitis of the penis and/or perineoscrotal region, which rapidly progresses and carries a high mortality. Eleven cases of Fournier's gangrene that had undergone an emergency procedure from 1985 to 1992 are described. Excellent results were achieved, with a survival rate of 91%. In our view, treatment of this disease entity is fundamentally based on early diagnosis, wide radical debridement of the affected area, frequent local treatment, debridement at the least sign of recurrence and early antibiotic therapy with three agents.

[Genital location of a clear-cell hidradenoma].

Clear cell hidradenoma of the penile prepuce progressing to malignancy transformation is rare and arises from the adnexal glands of the skin. It may present in nodular or ulcerated forms, which make it almost impossible to distinguish from spinocellular carcinoma. Treatment is by wide surgical excision. Local recurrence and distant metastasis rare.

[Fistula between ileal conduit and small intestine after cutaneous ureteroileostomy].

We report on a case of ileal conduit-enteric fistula which appeared early after ureteroileostomy using the Bricker technique. The appearance of gastrointestinal content through the stoma was the only sign. An ileogram permitted making the diagnosis. Conservative treatment was instituted and the fistula resolved spontaneously. The different diagnostic and therapeutic aspects of this uncommon complication after ureteroileostomy are discussed.

[Bilateral renal lymphoma].

Lymphomas can present as a solid tumor mass in one or both kidneys or compromise renal function directly or indirectly. Lymphoma should be discarded before performing surgical excision of a rapidly growing renal mass, particularly if involvement is bilateral. Reducing the renal mass may lead to difficulty in instituting specific chemotherapy for this tumor type.

[Medico-surgical management of renal leiomyosarcoma].

Because renal leiomyosarcoma is extremely rare, the experience in the management of this tumor type is necessarily scant. Our surgical and chemotherapeutic approach in a 17-year-old male patient with renal leiomyosarcoma achieved partial remission of tumor recurrence and a survival of 31 months following diagnosis.

[2 new cases of ++urethral diverticuli in women].

The first two cases of diverticulum of the female urethra seen in our Service are described. The secretion of purulent material from the urethra on vaginal compression prompted us to suspect this condition, which could not be confirmed radiologically in one case and a urethroscopy procedure was required. The etiopathogenesis of this disease is briefly reviewed and the therapeutic possibilities depending on the location of the urethral diverticulum are discussed.

[Lymphatic involvement predominating and revealing prostatic carcinoma].

The lymphatic system is the most common site of metastasis of prostatic carcinoma. However, carcinoma of the prostate presenting as lymphadenopathy is rare. It can present at any site and may sometimes mimic lymphoreticular tumors. The diagnosis is based on the histological findings. Histochemical techniques using immunoperoxidase demonstration of acid phosphatase and prostate specific antigen are fundamental in detecting the occult tumor of the prostate. Treatment is palliative and enlargement may occasionally remit with hormone therapy. The prognosis is invariably poor. Survival is less than 5 years irrespective of the response to treatment. Three cases are described herein: 2 presented as retroperitoneal mass and 1 as left lateral cervical lymphadenopathy.

[Primary retroperitoneal hydatidosis].

The case of a primary retroperitoneal hydatidosis in a 62 year-old patient found accidentally during an haematuria study is presented. Both the possible extraperitonization mechanisms and efficacy of ultrasound scanning and percutaneous puncture in the etiological diagnosis in cases of retroperitoneal mass are evaluated.
