[Nephritic colic caused by periureteral fibrosis resulting from metastasis from lobular carcinoma of the breast]. / Cólico nefrítico por fibrosis periureteral de metástasis de carcinoma lobulillar de mama.

OBJECTIVE: To report a rare case of renoureteral colic in a patient with a solitary left kidney, due to fibrosis around the renal pelvis and ureter from metastatic lobular carcinoma of the breast. METHODS/RESULTS: A 45-year-old patient consulted at the emergency services for pain in the left renal fossa that irradiated to the genital organs. Patient evaluation showed lid edema and oliguria. An abdominal ultrasound scan demonstrated left hydronephrosis. The cause of the obstruction could not be determined by imaging techniques. Exploratory lumbotomy was performed and the pelvis and ureter were released from the fibrotic covering. The histological analysis showed infiltration of the ureteral adventitia arising from lobular breast carcinoma. CONCLUSIONS: Retroperitoneal metastases that cause ureteral obstruction usually occur two years following diagnosis of the primary tumor. This is one of the few cases of ureteral obstruction from metastatic lobular carcinoma of the breast reported in the literature. Unlike the other cases, however, our patient showed a complicated genitourinary malformation.

[Vestibular approach in urinary incontinence in women. Original technic. Experience. Results]. / La vía de abordaje vestibular en la incontinencia de orina en la mujer. Técnica original. Experiencia. Resultados.

Presentation of an original technique to treat S.U.I. in women. This technique contains in itself many others, both in terms of the conceptual anatomical base on which it is inspired, and in the possibilities of its surgical application. Lisfranc's approach, supra-meatic and infra-clitoridean, allows to section both the pubo-urethral ligament and Colles fascia thus reaching into the Retzius. It makes possible the use of solid anatomical elements (pelvian fascia, elevator, urethro-vaginal septum, etc...) thus allowing to suspend the pelvian base from fascia ligaments or from the abdominal wall muscles. Sixty patient who had simple S.U.I. received treatment, with a 95% efficacy index based on the evaluation of the urodynamic, bacteriological and clinical studies. We conclude with an evaluation on the validity of the results obtained by emphasizing the high efficacy index, simplicity, low morbidity and short hospital stay.

[Surgical complications after 160 renal transplantations. Experience. Comments]. / Complicaciones quirúrgicas tras 160 transplantes renales. Experiencia. Comentarios.

The present study reviewed the complications observed in 160 renal transplants that had been performed from 1982 to 1992. Complications were observed in 27 cases (16.87%), which falls within reasonable limits and is similar to the complication rate reported elsewhere. The treatment utilized in these cases was highly effective and only 3 grafts (1.87%) were lost. The following complications were observed: obstructive uropathy (7 cases, 4.37%), fistula (18 cases, 11.25%), vascular complications (1 case, 0.62%) and other complications (1 case, 0.62%).

[Gonadal stromal tumor in childhood. Report of a case. Comments]. / Tumor de estroma gonadal en la infancia. Aportación de un caso. Comentarios.

A case of testicular gonadal stromal tumor in an 8-month-old boy is described. Patient evaluation revealed no hormonal alterations. The patient underwent orchidectomy and has remained tumor-free at two years follow-up, which meets the well-established criteria for benign tumors. A detailed anatomopathological description is presented.

[Stenosis of the urethra: modified external subcutaneous urethrotomy. Treatment of 22 patients]. / Estenosis de uretra: uretrotomía externa subcutánea modificada. Tratamiento en 22 pacientes.

The present study reports the results afforded by the Flores technique, a modification of the Monseur urethroplasty, in the surgical treatment of urethral strictures. The clinical, urodynamic, and biological data from medium-term follow-up are presented.
