Mesh Graft Urethroplasty-Still a Safe and Promising Technique in Mostly Unpromising Complex Urethral Strictures.

Long urethral strictures or even recurrent urethral strictures, mostly with scar tissue showing insufficient healing tendencies, are defined as complex and represent a big challenge in modern reconstructive urology. Initially, the treatment of complicated urethral strictures was associated with a high failure rate (20-40%) due to the growth of hair in the neourethra and a lack of sufficient suitable epithelium when scrotal skin was used. Although much effort was put into tissue engineering recently, harvesting and transplanting autologous tissue represent the standard of care for urethral substitution or augmentation.

Anterior Urethroplasty Using a New Tissue Engineered Oral Mucosa Graft: Surgical Techniques and Outcomes.

Purpose: We investigated whether tissue engineered material may be adopted using standard techniques for anterior urethroplasty.

Materials And Methods: We performed a retrospective multicenter study in patients with recurrent strictures, excluding those with failed hypospadias, lichen sclerosus, traumatic and posterior strictures. A 0.

Complications and mortality after radical cystectomy for bladder transitional cell cancer.

Purpose: We evaluated early postoperative complications and 3-month mortality after radical cystectomy using a standardized method to report complications.

Materials And Methods: We retrospectively collected data on all 358 consecutive patients who underwent radical cystectomy for nonmetastatic bladder transitional cell carcinoma at a tertiary academic referral center from January 2002 to December 2006. The Martin criteria were used to report complications, which were graded according to a 5-grade modification of the Clavien system.

Learning curve and preliminary experience with da Vinci-assisted laparoscopic radical prostatectomy.

Objective: To report our initial experience in the treatment of prostate cancer with robotic-assisted laparoscopic radical prostatectomy (RALP), evaluating our results in terms of learning curve, postoperative outcomes and positive surgical margins.

Material And Methods: From April 2005 to February 2006, a single surgeon performed 41 RALP using the da Vinci robot (Intuitive Surgical, Inc., Sunnyvale, Calif.

Prognostic accuracy of an artificial neural network in patients undergoing radical cystectomy for bladder cancer: a comparison with logistic regression analysis.

Objective: To compare the prognostic performance of an artificial neural network (ANN) with that of standard logistic regression (LR), in patients undergoing radical cystectomy for bladder cancer.

Patients And Methods: From February 1982 to February 1994, 369 evaluable patients with non-metastatic bladder cancer had pelvic lymph node dissection and radical cystectomy for either stage Ta-T1 (any grade) tumour not responding to intravesical therapy, with or with no carcinoma in situ, or stage T2-T4 tumour. LR analysis based on 12 variables was used to identify predictors of overall 5-year survival, and the ANN model was developed to predict the same outcome.

Evidence from robot-assisted laparoscopic radical prostatectomy: a systematic review.

Objective: To review the literature available on robot-assisted laparoscopic radical prostatectomy (RALP).

Methods: A literature search was performed using EMBASE, MEDLINE, and Web Science databases through a "free text" protocol, including the following terms: robotic radical prostatectomy, da Vinci, and radical prostatectomy. Three of the authors separately reviewed the records to select the papers relevant for the topic of the review, with any discrepancies solved by open discussion.

[Prevention of venous thromboembolism in urologic neoplasms].

Purpose: We report our past experience on a sample of patients who underwent pelvic surgery to treat infiltrating bladder tumours.

Results: We observed the highest incidence of TVP (33.3%, 3 out of 9) in those patients with higher risk due to anaesthesia and type of surgery.

[Obstructive uropathy secondary to recurrent pelvic endometriosis: description of a clinical case].

The typical presentation of endometriosis is pelvic pain. Patients with with endometriosis often have associated fertility disorders even if their relationship with the symptoms and signs of endometriosis is not evident. The first line of treatment for endometriosis must be surgery.
