[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.

[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.

[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.

[Is the Alb-Ghorab technic effective in priapism?].

The usefulness of the Alb-Ghorab technique is discussed. Of the different balano-cavernous shunt techniques, attention is focussed to the Alb-Ghorab, highlighting the result achieved in the case described herein.

[Glans penis necrosis secondary to gentian violet treatment].

We describe a patient who developed superficial necrosis of the glans penis from irritation after topical treatment with 1% gentian violet. The foregoing condition resolved after withdrawal of treatment. A differential diagnosis (sexually transmitted diseases, epidermoid carcinoma, etc.) is warranted on finding this type of lesion in the glans penis.

[An infrequent form of metastasis of carcinoma of the prostate].

A case of carcinoma of the prostate metastatic to breast is reported. We highlight its rarity, its relationship with estrogen treatment, and the poor prognosis of this condition which develops in the end stages of metastatic carcinoma of prostate.

[Renal cysts communicating with the excretory duct].

The paper reports 2 cases of cystic-pyelocalyceal communication one secondary to traumatism and the other one infection-induced, demonstrating the possibilities of using etiological diagnosis in these communications, and the therapy to be followed. Endoscopic manipulation is usually enough to allow correct diagnosis as well as treatment.

[Verrucous carcinoma of the penis: apropos of 2 cases].

Verrucous carcinoma accounts for approximately 5% of penile carcinomas. Verrucous carcinoma is a variety of squamous cell carcinoma with peculiar histologic features and a benign nature. We report two cases of this disease entity diagnosed in two patients aged 57 and 73 years, with a follow up of 2 and 3 years, who had been submitted to partial resection of the penis.

[Verrucous carcinoma of the penis: our caseload].

Verrucous carcinoma, a tumor that encompasses approximately 5% of all penile neoformations, is a variant of squamous cell carcinoma which is benign and has a peculiar histological behaviour. We report on three patients aged 57, 80 and 84 years with this tumor type who underwent surgery (circumcision in one case and partial penectomy in the remaining two cases). The literature is briefly reviewed and the epidemiological, clinical, diagnostic and therapeutic aspects are discussed.

[Non-instrumental traumatism of the urethra: our experience].

OBJECTIVES: To report our experience in the diagnosis and treatment of this type of urologic trauma. The results are analyzed in order to determine the best therapeutic approach and the literature reviewed. METHODS: The series comprised 9 males; 6 had rupture of the posterior urethra and 3 had anterior urethral trauma. Four cases underwent suprapubic drainage and delayed definitive treatment; early realignment of the urethra was performed in 3 cases, and the only patient with a penetrating injury immediately underwent a repair procedure. Urethral urethrotomy sufficed in one patient with partial rupture of the anterior urethra. Delayed treatment consisted of end-to-end anastomosis; one patient required pubic partial resection. RESULTS: Good results were achieved by end-to-end anastomosis; 3 patients have been discharged and one required internal urethrotomy. Two of these patients have remained impotent. The patients submitted to early realignment of the urethra are managed well with regular dilatation and internal urethrotomy in some cases. CONCLUSIONS: We found suprapubic drainage and delayed repair superior to early realignment in those cases with posterior urethral injury. In our view, delayed end-to-end anastomosis, with or without pubic resection can be performed in virtually all cases. We advocate immediate repair of penetrating injuries to the anterior urethra.
