Experimental use of a cellulosic biopolymer as a new material for suburethral sling in the treatment of stress urinary incontinence.

Purpose: To analyze the interaction between the cellulose exopolysaccharide (CEC) and urethral tissue when used as a pubovaginal sling.

Materials And Methods: Forty Wistar rats were divided into four groups. In groups A and B the cellulose exopolysaccharide (CEC) was implanted around the urethral tissue (bladder neck below the upper margin) and the rats were sacrificed at 30 and 90 days.

Long-term followup of penile carcinoma treated with penectomy and bilateral modified inguinal lymphadenectomy.

Purpose: We evaluated modified inguinal lymphadenectomy in the treatment of penile carcinoma, analyzing the rate of complications compared to complete inguinal lymphadenectomy, the complications in performing lymphadenectomy and penectomy concomitantly, and the long-term locoregional recurrence rate.

Materials And Methods: A total of 26 patients with squamous cell carcinoma of the penis were clinically assessed, and underwent penectomy and bilateral modified inguinal lymphadenectomy at the same operative time. Frozen section analysis of lymph nodes was performed and if metastases were detected a complete ipsilateral inguinal dissection was performed.
