[Scrotal leiomyoma: report of a case]. / Leiomioma de escroto: aportación de un caso.

Scrotal leiomyoma is a benign rare tumour, asymptomatic, which origin is the dartos muscle and the election treatment is surgical. We report a new case in a 68-year-old patients with a 10 years history of a scrotal tumour and anatomopathological diagnostic post surgery was leiomyoma.

[Extrinsic ureteral obstruction secondary to appendiceal mucocele]. / Obstrucción ureteral extrínseca secundaria a mucocele apendicular.

OBJECTIVE: To report a case of extrinsic ureteral obstruction arising from mucocele of the appendix and review the clinical, diagnostic and therapeutic aspects of this appendiceal pathology of interest in urology. METHODS: A 71-year-old female patient that had previously undergone radical gynecological surgery and postoperative radiotherapy presented with right lumbar pain. Patient evaluation by ultrasound, IVP and CT showed a pelvic mass causing right extrinsic ureteral obstruction. Release and reinsertion of the right ureter and appendectomy were performed. RESULTS: The anatomopathological study showed an appendiceal mucinous cystadenoma. The patient is asymptomatic after surgery. CONCLUSIONS: Appendiceal mucocele is a dilatation of the vermiform appendix due to collection of mucoid material that is frequently produced by a cystadenoma. The presenting feature is usually that of acute appendicitis. The definitive diagnosis is based on the anatomopathological findings. Treatment is by appendectomy for the benign tumors and by right hemicolectomy in a second stage procedure for malignant tumors. This appendiceal pathology should be taken into account in the differential diagnosis of right extrinsic ureteral obstruction.

[Leiomyoma of the bladder. Report of a case]. / Leiomioma de vejiga. A propósito de un caso.

Benign bladder tumors of mesenchymal origin have a very low appearance incidence, being the most frequent the leiomyoma. We report new case, making a discussion about the complementary tests needed for the diagnose.

[Inverted papilloma of the prostatic urethra]. / Papiloma invertido de uretra prostática.

The inverted papilloma is a rare urothelial tumor, and its localization at the prosthatic urethra is also exceptional. We present a case of inverted papilloma of the prostatic urethra in a 72 years-old male, with symptoms of urinary flow obstruction. The diagnose is obtained after urethrocistoscopy and transurethral resection at the same time. We discuss about the etiology, clinical presentation, diagnose and treatment of this rare tumor, making special attention to its malignancy ability.

[High-flow priapism in the pediatric age: review]. / Priapismo de alto flujo en edad pediátrica: revisión.

OBJECTIVE: To review the literature on high flow priapism in children and analyze the etiology, pathophysiological mechanism, diagnostic tests, treatment and complications. METHODS: The literature is reviewed and an additional case of posttraumatic arterial priapism in an 11 year-old boy treated at our hospital is presented. RESULTS: 24 cases of high flow priapism in children were found; 18 had a history of genitoperineal trauma, 5 had sickle cell anemia and one child had Fabry's disease. Diagnosis was based on patient history, intracavernous blood gases and echo doppler findings. Fourteen patients with posttraumatic priapism, one patient with sickle cell anemia and the child with Fabry's disease were treated by pudendal arteriography with embolization. The immediate results and erectile function were good. CONCLUSIONS: Genitoperineal trauma is the most common cause of arterial priapism in children. High flow must be considered in children with sickle cell disease and priapism that do not respond to conventional treatment. Pudendal arteriography with embolization is the treatment of choice. Erectile function is recovered after treatment.

[Colonic perforation in percutaneous surgery of the kidney. Report of two cases]. / Perforación colónica en la cirugía renal percutánea. Presentación de dos casos.

We show our experience about iatrogenic damage of colon secondarily to percutaneous surgery of the kidney. One of them treated by means of open surgery, the other by conservative procedures. Making discussion on risk factors, as well as the diagnostic therapeutical aspects.

[Neurophysiologic techniques in the diagnosis of erectile dysfunction: study of 105 cases]. / Técnicas neurofisiológicas en el diagnóstico de la disfunción eréctil: estudio de 105 casos.

OBJECTIVE: To present the results of the neurophysiological diagnostic evaluation in patients with erectile dysfunction. METHODS: 105 consecutive patients with complaints of erectile dysfunction were evaluated. The patients were divided into five groups according to their history: surgery/trauma, diabetes, vascular disease, toxicity, and no antecedents. Neurophysiological examination, laboratory tests, hormone and vascular studies were performed. Patient evaluation included neurophysiological studies on nerve conduction velocity (NCV), bulbocavernosus reflex (BCR), spinal and scalp somatosensory evoked potentials from the posterior tibial nerves (SEPt) and from the dorsal penile nerve (SEPp). In selected cases, electromyography and neuroimaging studies were done. RESULTS: 71 patients (67.62%) showed organic alterations; 57 of these patients had abnormal neurophysiological tests. Ranked in order of incidence, the tests were abnormal for NCV in 46/105 patients, SEPt 37/105, BCR 35/105 and SEPp in 30/105 patients. The incidence of BCR abnormalities was higher than that of the NCV only in the surgery/trauma group, probably due to a higher prevalence of local injuries, while NCV showed the highest incidence of abnormal results in the other groups of patients. Only 8 patients showed normal NCV with abnormal BCR, SEPp and/or SEPt (14.04% of patients had neurophysiological disturbances). CONCLUSION: In this study, most of our patients showed vascular, neurologic or both abnormalities, and were rarely associated with other factors. In our view, NCV is the technique of choice in the assessment of neurological disorders in patients with erectile dysfunction, whereas the other less sensitive tests are considered to be indicated basically in erectile dysfunction highly suspected as having an underlying neurogenic cause.

Case report describing a solid renal mass as an incidental finding while evaluating a different condition. This is an oncocytoma infiltrating perirenal fat. The various aspects of the process are described.

[Primary signet cell adenocarcinoma of the bladder]. / Adenocarcinoma de células en anillo de sello primario de vejiga.

The primary signet-ring cell adenocarcinoma of the bladder is a rare tumor, with great biological aggressivity and bad prognosis. We report a clinical case of a 65 years old patient, starting with bladder irritative symptoms and suffering from advanced disease at the initial diagnosis. We review clinical and etiopathogenic aspects about this entity.
