[Giant retroperitoneal liposarcoma]. / Liposarcoma retroperitoneal gigante.

A case of giant retroperitoneal liposarcoma is described. Treatment was by radical surgery, using the anterior approach, with preservation of the renal unit. The diagnostic procedure is briefly discussed and the literature reviewed.

[Spontaneous extravasation of urine at the pyelo-caliceal level. Spontaneous urinomas]. / Extravasación espontánea de orina a nivel pielo-calicial. Urinomas espontáneos.

We present two cases of spontaneous rupture of the excretory tract within the context of reno-ureteral colic due to lithiasis. We comment on the etiopathogenic aspects and underscore the need for emergency evaluation in patients with very severe nephric colic and/or symptoms of peritoneal irritation (ileus, abdominal guarding), and temporary urinary diversion must be performed via nephrostomy as a palliative procedure for the symptoms and to avoid complications.

[Erythrocytosis and renal adenocarcinoma]. / Eritrocitosis y adenocarcinoma renal.

Contribution of one left renal adenocarcinoma in a 54-year old women, where the initial data was the finding of erythrocytosis discovered during routine laboratory tests performed by her gynaecologist. Review of the diagnostic and therapeutic procedures followed in this case, establishing a differentiation between erythrocytosis and polyglobulia. Normalization of the hemogram following extended nephrectomy is emphasized. This case history is considered to be of interest due to its presentation pattern. Finally, we believe that faced to an erythrocytosis of unknown etiology, a renal tumoral disease, more specifically a renal adenocarcinoma, should be suspected.

[Review of 36 trigono-cervico-prostatectomies, carried out for prostatic pathology]. / Revisión de 36 trigono-cérvico-prostatotomías, practicadas por patología prostática.

Review of 36 trigone-cervix-prostatectomies, performed in our services. Studies made before and after the procedure. Indications for trigone-cervix-prostatectomies. Complications and results obtained. Trigone-cervix-prostatectomies as an alternative to prostate transurethral resection, in a highly selected group of patients, because of its simplicity and better results.

[Prostatic abscess--new diagnostic and therapeutic guidelines]. / Abscesos prostáticos--nuevas pautas diagnósticas y terapéuticas.

Five prostatic abscesses treated in our Unit over the last three years (1988, 89, 90) are presented. Both the mode of presentation and symptoms as well as the course of treatment followed (three percutaneous drainage through the perineum, lead by ultrasound scanning, one endoscopic abscess incision with Collins' knife and one resolved with antibiotics subsequently needing TUR of the prostatic adenoma) are reviewed. The change of attitude in the treatment of prostatic abscesses (Ultrasound-lead percutaneous drainage) and the major usefulness of ultrasound scanning for diagnosis, treatment and subsequent follow-up are emphasized.

[Diagnostic guidelines in female ureteral diverticulum]. / Pauta diagnóstica en divertículos uretrales femeninos.

A case of diverticulum of the female urethra is presented which was successfully treated surgically. The diagnostic methods used are described, highlighting the usefulness of ultrasound in making the topographic diagnosis. Furthermore, because it is a non-invasive imaging technique, it can be used in screening the cases. Performing positive pressure urethrography is advocated. If the catheter for this purpose is unavailable, a substitute can be easily assembled.
