Modified inguinal lymphadenectomy causes a lower complication rate than complete inguinal lymphadenectomy. Bilateral modified inguinal lymphadenectomy performed at the same time as penectomy does not increase the complication rate. When frozen section analysis is negative bilaterally, 5.5% of inguinal regions might still harbor occult metastasis. Modified inguinal lymphadenectomy is recommended as a staging procedure in all patients with T2-3 penile carcinoma. A straight followup is required for 2 years since all recurrence was within this period.

The injection of bulking agents into the urethral submucosa is designed to create artificial urethral cushions that can improve urethral coaptation and hence restore continence. Ideally, a urethral bulking agent should be non-immunogenic and biocompatible, leading to minimal inflammatory and fibrotic response. The authors present a case report of a granulomatous reaction leading to urethral prolapse, 3 months after the transurethral injection of calcium hydroxylapatite. To our knowledge, this is the first granulomatous reaction described after calcium hydroxylapatite injection.

Objective: The incorporation of bowel segments for urinary tract reconstruction may induce intestinal mucosal changes with the development of metabolic, nutritional, gastrointestinal and carcinogenic complications. The early histological and histochemical changes of the intestinal mucosa in contact with the feces-urine mixture, are evaluated in the present study. Materials and Methods: Twelve rats (operated group) were submitted to a vesico-colonic anastomosis, and 10 rats (control group) underwent a sham operation (the colon was opened and immediately sutured). On the operated group, the left colon was divided into 3 equal portions and the middle segment was used for the bladder-colonic anastomosis. After 20 weeks, the animals were sacrificed and the entire left colon in each group, as well as the bladder and the vesico-colonic anastomosis in the operated group, was removed. The proximal, middle (anastomotic site in the operated group and sutured portion in the control group) and distal colon were used for histological and histochemical studies. Results: Metaplasia, chronic inflammatory process and fibrosis were significantly greater at the anastomotic site compared to the middle segment of the control group. There were no differences in both groups in terms of dysplasia, atrophy and hypertrophy either on the proximal, middle or anastomotic area and distal portion of the left colon. All animals in the operated group showed a reduced presence of sulfomucin and an increase in the sialomucin content. Conclusion:The histological changes observed in this study may suggest a precancerous phenomenon.

Sling procedures have been around for decades in the management female stress urinary incontinence (SUI), but only in the past decade they have become the preferred technique. Minimally invasive procedures are the procedure of choice in many centers for your efficacy and low morbidity. The tendinous urethral support (TUS) represents an anatomical approach that consists in placing a midurethral low tension tape anchored to the tendinous arc bilaterally. From February 1999 to October 2000, 25 female patients (mean age: 53 years old), with SUI underwent TUS procedure, and 23 were available for follow-up. Those patients were followed until 72 months. After six months, 20 (87%) patients were dry, 2 (8.7%) improved and 1 (4.3%) incontinent. However, at the last evaluation, 15 (65.2%) investigation.

Com a urbanização das últimas décadas, houve aumento na construção de Estações de Tratamento de Esgoto (ETE), tendo a despoluição dos rios e a diminuição dos problemas de saúde pública como escopo. O processo de tratamento de esgotos gera um resíduo conhecido como lodo, rico em matéria orgânica e outros elementos importantes como nitrogênio e fósforo. Para esse resíduo devem-se buscar alternativas para a sua correta disposição para que não acarrete em problemas ambientais. Normalmente as formas de disposição mais comuns são os aterros sanitários e/ou incineração, gerando custos para os responsáveis pelo tratamento. Uma alternativa para essa disposição é a utilização do lodo de esgoto em solos agrícolas, entretanto, a possível presença de poluentes como metais, patógenos e compostos orgânicos persistentes podem provocar impactos ambientais negativos.
