To evaluate the urinary outcomes and preservation of erectile function in patients with pelvic fracture-related urethral injury (PFUI) after nontransecting spongiosum anastomotic urethroplasty (NTSAU).Fifty-nine male patients with PFUI following traumatic pelvic fracture underwent NTSAU. Inclusion criteria were age 18-60 years, posterior urethral stenosis <2.5 cm without previous urethroplasty,...
To explore selection of the procedures in one-stage urethroplasty for treatment of coexisting urethral strictures in the anterior and posterior urethra.Between 2008 and 2014, a total of 27 patients with existing strictures simultaneously at anterior urethra and posterior urethra were treated in our hospital. Two types of procedures were selected for treatment of the anterior urethral strictures. A...
To investigate the long-term outcome of ileal ureteric replacement using a proximal antirefluxing technique for the treatment of long-segment ureteric strictures.Between January 1997 and December 2013, 41 patients with a long ureteral stricture or defect and 3 patients with unilateral mid-lower ureteral cancer (20 bilateral and 24 unilateral, 28 males and 16 females) were treated by ureteral substitution...
To evaluate the effect of reconstruction of penile urethra with the 3-dimensional (3-D) porous bladder acellular matrix (BAM) in a rabbit model.In 30 male rabbits, a ventral urethral mucosal defect (1.5 × 0.8 cm) was created. Substitution urethroplasty was performed with 5% peracetic acid (PAA)-treated BAM (3-D porous BAM; 15 rabbits, PAA-treated BAM group) and non–PAA-treated BAM (15 rabbits; non–PAA-treated...
To report the outcome of 1-stage urethroplasty using lingual mucosal grafts (LMGs) and buccal mucosal grafts (BMGs) for the treatment of male urethral strictures associated with genital lichen sclerosus (LS).This was a descriptive, observational retrospective study of male patients with urethral strictures who underwent 1-stage mucosal graft urethroplasty using different substitute materials for reconstructive...
To investigate the feasibility of replacing urinary epithelial cells with oral keratinocytes and transforming growth factor β (TGF-β)1 siRNA transfected fibroblasts seeded on bladder acellular matrix graft (BAMG) to reconstruct urethra.Autologous oral keratinocytes and TGF-β1 siRNA transfected fibroblasts were seeded onto BAMGs to obtain a tissue-engineered mucosa. The tissue-engineered mucosa was...
To evaluate the results of ancillary procedures for posterior urethroplasty and compare them with the severity of urethral stricture.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...
