    OBJECTIVE: To describe the complications of transperineal end-to-end anastomotic urethroplasty in patients with posterior urethral strictures resulting from pelvic fracture.

    MATERIALS AND METHODS: A total of 573 patients, who underwent bulboprostatic anastomosis for posterior urethral strictures, were enrolled in this study. Distraction defects were measured using retrograde urethrography combined with voiding cysto-urethrography. All patients underwent perineal excision and primary ...

    BACKGROUND/AIMS: Tissue inhibitor of metalloproteinases-1 (TIMP-1) has been reported to upregulate in urethral scar. However, the underlying molecular mechanisms remain undefined.

    METHODS: Here, we studied levels of TIMP-1 and α-smooth muscle actin (α-SMA) in the fibroblasts isolated from urethral scar tissues, compared to the fibroblasts isolated from normal urethra. Then we either overexpressed TIMP-1, or inhibited TIMP-1 by lentiviruses carrying a transgene or a short hairpin small ...

    OBJECTIVES: To evaluate the results of ancillary procedures for posterior urethroplasty and compare them with the severity of urethral stricture.

    METHODS: A total of 301 patients (average age: 36 years) with posterior urethral strictures due to pelvic fracture urethral distraction defects were included in the study. Delayed transperineal bulboprostatic anastomosis was performed 6-24 months (mean 10 months) after pelvic fracture urethral distraction defects. Simple perineal anastomosis: ...

    OBJECTIVES: We evaluated the applications and outcomes of substitution urethroplasty, using a variety of techniques, in 65 patients with complex, long-segment urethral strictures.

    METHODS: From January 1995 to December 2005, 65 patients with complex urethral strictures >8cm in length underwent substitution urethroplasty. Of the 65 patients, 43 underwent one-stage urethral reconstruction using mucosal grafts (28 colonic mucosal graft, 12 buccal mucosal graft, and 3 bladder mucosal graft), ...

    PURPOSE: We investigated the possibility of urethroplasty with a free graft of colonic mucosa for long, complex urethral strictures. We report our initial experience with colonic mucosa graft urethroplasty for such urethral strictures in 16 patients.

    MATERIALS AND METHODS: Between September 2000 and December 2002, 16 patients with a long, complex urethral stricture were treated with colonic mucosal graft urethroplasty. Patients had undergone an average of 2.5 previous unsuccessful ...

    AIM: To investigate the possibility of urethral reconstruction with a free colonic mucosa graft and to present our preliminary experience with urethral substitution using a free graft of colonic mucosa for treatment of 7 patients with complex urethral stricture of a long segment.

    METHODS: Ten female dogs underwent a procedure in which the urethral mucosa was totally removed and replaced with a free graft of colonic mucosa. A urodynamic study was performed before the operation and ...

    BACKGROUND: Urethrorectal fistulas (URF) in patients with complex posterior urethral strictures are rare and difficult to repair surgically. There is no widely accepted standard approach described in the published literature.

    OBJECTIVE: The aim of this study was to describe the outcomes of various operative approaches for the repair of URFs in patients with complex posterior urethral strictures.

    DESIGN, SETTING, AND PARTICIPANTS: From January 1985 to December 2007, 31 patients (age: 6-61 ...

    The aim of this study was to evaluate erectile function in patients with panurethral stricture after urethral reconstruction. Totally, 65 patients were enrolled. Different urethral reconstructions were performed according to the details of urethral strictures. The erectile function was evaluated before and after surgery. The length and location of stricture and duration from initial diagnosis to operation were recorded. The International Index of Erectile Function-5 (IIEF-5) scores, the ...

    OBJECTIVES: We evaluated the efficacy of bulbourethral composite sling procedure in the treatment of male urinary incontinence after radical prostatectomy, transurethral resection of the prostate, or prostatic enucleation for benign prostatic hyperplasia, and posterior urethroplasty.

    METHODS: Between May 2000 and April 2005, a bulbourethral composite sling was performed in 26 patients with acquired urinary incontinence. Eight (30.8%) of these patients had severe urinary incontinence, and ...

    OBJECTIVE • This study was to evaluate donor-site complications of lingual mucosal graft harvesting for substitution urethroplasty. PATIENTS AND METHODS • 110 patients with anterior urethral strictures or hypospadias underwent lingual mucosal grafts (LMGs) urethroplasty. Dual LMGs were harvested from both sites separately or a long mucosal graft was harvested from one side to other side of tongue in 29 patients (group one); a shorter mucosal graft was harvested from one side of tongue in ...

    PURPOSE: We evaluated outcomes and donor site complications in male patients with complex urethral strictures who underwent urethroplasty using with long strip oral mucosal grafts. We also analyzed whether a lingual mucosa graft is a good substitute for repairing long segment urethral strictures.

    MATERIALS AND METHODS: This retrospective study was done in 81 male patients with complex urethral strictures who underwent oral mucosal graft urethroplasty. Patients with long segment (8 cm or ...

    Urethral fibrosis is an important pathological feature of urethral stricture. TGF-β1 and CXC chemokine receptor 3 (CXCR3) signaling have been reported as the critical pathways involved in the pathology of fibrosis. Here, we collected the urine samples from the patients with recurring urethral stricture, recurring stricture treated by cystostomy, and age- and gender-matched healthy people. ELISA detection revealed that TGF-β1 level was significantly up-regulated for the urethral stricture ...

    BACKGROUND: Female urethral injury is rare, and there is no accepted standard approach for the repair of urethral strictures.

    OBJECTIVE: To evaluate the efficacy of transpubic access using pedicle tubularized labial urethroplasty for urethral reconstruction in female patients with urethral obliterative strictures and urethrovaginal fistulas.

    DESIGN, SETTING, AND PARTICIPANTS: Between January 1996 and December 2006, eight cases of female urethral strictures associated with urethrovaginal ...
