[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.

[Methods of endoluminal treatment of urethral stenosis up to the end of the 19th Century].

Ever since Hippocrates, physicians have managed patients that suffered from urethral stricture. To that end, genius and imagination put to the service of scientific knowledge, have produced numerous apparatus, instruments and methods of a varied nature, with the aim of allowing urine passage through the strictured urethra. Illustrious names such as Andrés Laguna or Francisco Díaz, and other not so well known. Spanish and foreigners, are mentioned in this paper in an intent to contribute a brief view on the evolution of the methods used to treat urethral stricture up to the end of the 19th Century.

[Testicular tumors: our follow-up and treatment protocol. Report of 30 cases].

The high incidence of testicular tumors seen in our setting prompted us to review our therapeutic and follow-up protocols and assess patient survival and course within the period spanning June, 1989 to August, 1992. During this 38-month period, we diagnosed a total of 30 cases (15 seminoma, 2 pure embryonal carcinoma, 8 mixed embryonal, 3 lymphoma and 2 Leydig cell tumors). Apart from orchidectomy, we utilized radiotherapy, chemotherapy and resection of residual tumor mass, according to the histological type and tumor stage. Of the 15 seminomas, there was 1 death (6%), 9 cases (60%) are tumor free with a mean survival of 25 months, and 5 cases (34%) are in partial remission at 11.3 months mean follow-up. Of the 10 nonseminomatous tumors, there was 1 death (10%), 5 patients (50%) are in complete remission at 23.6 months (mean), 3 (30%) are in partial remission at 19.3 months (mean) and 1 (10%) is in frank progression as manifested by the unresectable masses of the retroperitoneal lymph nodes. The survival rate for the seminoma group was 94% and 90% for the nonseminomatous tumors.

[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.

[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.

[Impotence caused by venous leakage: surgical treatment. Short- and mid-term results].

We reviewed the results achieved by ligation of the deep dorsal vein of the penis in 14 males with erectile dysfunction secondary to venous leakage. Prostaglandin E1 injection, echo Doppler and cavernosometry were utilized for the diagnosis. Surgical correction was performed when the cavernosometric flow required for erection was more than 200 cc/minute. The patients had a follow-up evaluation at 3, 6 and 12 months postoperatively. At one year, 4 (28.5%) patients showed good results and 10 (71.4%) poor. The factors that may influence the short, medium and long-term results are briefly described.

[Symptomatic treatment of benign hypertrophy of the prostate. Comparative study of prazosin and serenoa repens].

Forty-five patients diagnosed as having BPH and clinically diagnosed micturition disorders were entered in a therapeutic protocol. Twenty-five patients received Prazosin and the remaining 20 patients were treated with Serenoa Repens for a period of 12 weeks. The symptomatology was assessed by flowmetry and the patients were questioned as to the irritative symptoms. It can be concluded from the study that Prazosin is slightly more effective in controlling the irritative symptoms produced by BPH.

[Spontaneous renocolic fistula secondary to pyonephrosis of lithiasic etiology].

Description of one case of spontaneous fistulization between a renal calix and a descending colon, secondary to lithiasic pyonephrosis. Diagnosis was carried out by means of ascending pyelography without it being clinically suspected. Treatment is surgical, combining nephrectomy, fistula resection and closure of the colic gap. Etiology, favouring factors, diagnosis and treatment are explained.

[Cytology positive for malignant cells in hydrocele secondary to testicular seminoma].

Finding tumor cells in the fluid of hydrocele secondary to testicular tumor is rare and may be due to the fact that hydrocele fluid cytology has not been studied systematically. The presence of malignant cells in the hydrocele fluid may be ascribed to two mechanisms: retrograde lymphatic flow from the infiltrated retroperitoneal lymph nodes or from tumor directly invading the tunica albuginea and vaginalis testis, with cells passing into the cavity of the vaginalis. Only two cases of hydrocele secondary to testicular seminoma with vaginalis fluid cytology positive for malignant seminomatous cells have been previously reported in the literature. To our knowledge, the case reported herein is the third. These three cases are briefly discussed.
