INTRODUCTION: Radical prostatectomy is the mainstay of treatment for prostate cancer. The vesicourethral anastomosis is a critical step, which most likely impacts urinary continence and urethral stenosis. To date, it still remains unclear whether interrupted and continuous suturing for the anastomosis have different outcomes. Therefore, the aim of this systematic review and meta-analysis is to compare different suture techniques for vesicourethral anastomosis in terms of surgical and functional parameters...

Limited numbers of pediatric stenosis of external orifice of urethra have been reported. We report a case of congenital stenosis of external orifice of urethra in a female child who underwent meatoplasty. As an initial strategy for congenital stenosis of external orifice of urethra in girls, dilatation of stenosed urethral meatus may be another management of choice.

BACKGROUND: No study has examined the possibility to perform an organ sparing strategy in older patients with penile carcinoma, and amputation is frequently proposed. We report our experience of interstitial brachytherapy for the conservative treatment of penile carcinoma confined to the glans in patients aged of 70years and more. METHODS: A total of 55 patients candidates to conservative brachytherapy were identified. Median age was 73.8years (range: 70-95years)...

INTRODUCTION: Two reports have found that urethral plate (UP) widths <8 mm before tubularized incised plate (TIP) incision increased urethroplasty complications. The present study measured pre-incision UP width in consecutive boys undergoing TIP to determine if it affected outcomes. METHODS: The present study followed the method previously used by Holland and Smith, and Sarhan et al. to measure UP width before creating glans wings or performing midline plate incision in consecutive patients with primary hypospadias and ventral curvature <30°, who all underwent TIP repair (Summary Fig...

OBJECTIVE: Urethral stenosis is a disease in which the lumen of the urethra becomes constricted by fibrosis. Such stenoses have been treated by urethral dilation using a bougie and optical internal urethrotomy (OIU). Recently, high-pressure balloon dilation (BD) has been developed as a new treatment method for urethral stenosis. The present study compared the effectiveness of urethral dilation by BD and OIU. METHODS: Twenty-two patients of urethral stenosis were treated at Yokohama City University Medical Center between 2005 and 2015...

OBJECTIVE: To present our technique for staged urethroplasty with buccal mucosa graft. METHODS: The patient presented is a 42 year-old male with a history of congenital hypospadias repaired as a child. He developed a penile urethral stricture at age 30 and was managed with self intermittent dilation. Recently, dilation became more difficult, and he was referred for reconstruction. Work-up revealed a high-grade stricture extending from the meatus to the site of the previous anastomosis at the penoscrotal junction...

Background: Although the breakage of a Sachse's knife blade is already a rare event while performing optical internal urethrotomy, a double failure appears to be at the same time a unique and a challenging complication to manage since no reference has emerged from literature review. Case Presentation: A male patient, 80 years of age, underwent retreatment of recurrent urethral stricture that occurred after transurethral resection of the prostate. The latter was complicated by severe intraoperative urethrorrhagia; this is the reason he was transferred from another institution where at first a suprapubic cystostomy was carried out, followed by urethral recanalization through internal urethrotomy and finally he underwent intracavernous Sachse's knife blade discharge...

Recurrent stenosis is the main reason inducing the failure of urethral stricture treatment. Our previous study has found that the 316L type Cu bearing stainless steel (316L-Cu SS) showed antimicrobial activity and anti-encrustation performance when it was used for relieving urethral obstructer. However, whether it can reduce the occurrence of fibrosis or not, we need further investigation to compare the cellular and molecular responses of human urethral scar fibroblast cells (USFCs) on 316L-Cu SS and medical grade 316L stainless (316L SS, as a control)...

Gilad Amiel, Zaher Bahouth, Boaz Moskovitz, Sarel Halachmi, Ofer Nativ
Stents are widely use in endoscopic urological procedures. One of the most important indications is the treatment of urinary tract strictures. Allium™ Medical has introduced several types of stents for the treatment of different types of urinary tract strictures, based on anatomic location. All the stents are made of nitinol and coated with a co-polymer that reduces encrustations. These stents are self-expandable and have a large caliber and a high radial force. They have different shapes, designed especially for the treatment of each type of stricture...
