AIM: To improve treatment results in patients after multiple hypospadias repairs by optimizing the postoperative management. MATERIALS AND METHODS: Eighty-two patients (mean age 48.1+/-15.3 years) with urethral strictures secondary to failed hypospadias repairs underwent staged graft urethroplasty using oral mucosa (cheek, lip, tongue) as a grafting material. In 62 patients, at the end of surgery the bladder was drained with a standard Foley catheter. In twenty patients the bladder was drained with a modified silicone urethral catheter, which had an additional channel for delivering drugs and removing the urethral wound effluent, and a second additional channel for inflating a balloon fixed to the catheter tube at different parts of the catheter...

A 48-year-old woman with a history of voiding difficulty visited our hospital. Magnetic resonance imaging revealed a periurethral tumor, which was pathologically diagnosed as an adenocarcinoma via transperineal needle biopsy. Radical cystectomy and urethrectomy were performed, and the urinary tract was reconstructed using an ileal conduit. Pathological examination of a resected specimen confirmed adenocarcinoma of the urethral diverticulum. The patient received adjuvant gemcitabine and cisplatin chemotherapy...

INTRODUCTION/OBJECTIVE: Proximal hypospadias is one of the most challenging conditions that pediatric urologists have to deal with. Many procedures have been devised over the years, but nothing has been proven to be the best option. Although there have been some attempts at correcting severe hypospadias in one procedure, most have advocated a staged approach. The classic approach - laying penile skin or a graft within a split glans followed by glanuloplasty at the second stage - by definition requires two operations on the glans...

OBJECTIVE: To compare the long-term efficacy of Young-Dees bladder neck reconstruction (YDBNR) alone versus YDBNR plus BNI in patients with urinary incontinence caused by urethral sphincter insufficiency. PATIENTS AND METHODS: Between 1987 and 2006, we assessed the continence rates obtained with YDBNR and BNI as a supplementary treatment for persistent outlet insufficiency in patients with neurogenic bladder (group-1, n = 35) and bladder exstrophy (group-2, n = 20)...

INTRODUCTION: Severe genital abnormalities such as urogenital sinus and urethral duplication with ectopic urethra in the rectum represent a major challenge in reconstructive urology. OBJECTIVE: We aimed to review our cases presenting with functional ectopic urethra implanted in the rectum that were treated through an ASTRA approach. METHODS: We reviewed the medical records of all patients who had undergone an ASTRA approach from 2005-2016...

OBJECTIVE: To evaluate the success of urethroplasty for urethral strictures arising after erosion of an artificial urinary sphincter (AUS) and rates of subsequent AUS replacement. PATIENTS AND METHODS: From 2009-2016, we identified patients from the Trauma and Urologic Reconstruction Network of Surgeons and several other centers. We included patients with urethral strictures arising from AUS erosion undergoing urethroplasty with/without subsequent AUS replacement...

Reconstructive surgery for urethral stricture disease seeks to re-establish long-lasting urethral patency while minimizing associated adverse effects. In recent years, genitourinary reconstructive surgeons have developed and refined a number of techniques that seek to decrease the impact of urethroplasty on local tissues including blood supply and innervation. This review presents an outline of recent advances in urethral reconstructive techniques that seek to minimize surgical impact, including tissue preservation, tissue engineering, and minimally invasive approaches and reviews the current state of the literature related to these techniques...

OBJECTIVE: To determine if age is an independent predictor of surgical success in patients undergoing urethroplasty. Urethroplasty performed by excision and primary anastomosis depends on vascular collateralization. Successful augmented urethroplasty depends on graft neovascularization. Older patients have more comorbid conditions including peripheral vascular disease associated with reduced penile blood flow. MATERIALS AND METHODS: A retrospective review of urethroplasties from 11 institutions...

INTRODUCTION: Tissue engineering of corporal tissue is a new development in otherwise untreatable erectile dysfunction and in urethral reconstructions to treat hypospadias or severe urethral stricture disease. Multiple complications can arise with the current treatments, whereas engineered tissue, if well vascularized and existing of autologous cells, may lead to better results. The aim of this review was to provide an overview of literature on cell seeded based tissue engineering of corporal penile tissue...

INTRODUCTION: Radial forearm free flap (RFFF) tube-in-tube phalloplasty is the most performed phalloplasty technique worldwide. The conspicuous donor-site scar is a drawback for some transgender men. In search for techniques with less conspicuous donor-sites, we performed a series of one-stage pedicled anterolateral thigh flap (ALT) phalloplasties combined with RFFF urethral reconstruction. In this study, we aim to describe this technique and assess its surgical outcome in a series of transgender men...

OBJECTIVE: To evaluate the efficacy of the Memokath stent in managing recurrent bulbar urethral strictures. MATERIALS AND METHODS: This is an investigative pilot stage 2A study in patients with a recurrent bulbar urethral stricture who underwent a Memokath stent implant from January 2014 to January 2016 in a single high-volume centre for urethral reconstruction. The Memokath stent (Pnn Medical A/S, Kvistgaard, Denmark) is manufactured from nitinol, a biocompatible alloy of nickel and titanium, which is endoscopically placed...

With current technological advancement and availability of synthetic materials used in inguinal hernia repair, a recurrence after first intervention is not a common and important adverse event. On the other hand, however, some patients complain about chronic pain of the operated site after surgeries using a polypropylene mesh. Many patients are constrained to a prolonged use of analgesics and increased frequency of control visits, which may eventually result in loss of trust in the operator. Every surgical intervention is associated with the risk of immediate or delayed complications...

To evaluate the histological characteristics of decellularized human urethra after transplantation into the rat omentum and compare in vivo cell seeding with perfusion-based and cell sheet urethral regeneration. Eight adult human male urethras accompanied with the surrounding corpus spongiosum were obtained. The tissues were decellularized with detergent-based method. The efficacy of decellularization and extracellular matrix preservation was evaluated by several techniques. Decellularized scaffolds were transplanted into the omentum of 12 male rats and located into the scrotum...

BACKGROUND: Female-to-male gender-confirmation surgery (GCS) includes removal of breasts and female genitalia and complete genital and urethral reconstruction. With a multidisciplinary approach, these procedures can be performed in one stage, avoiding multistage operations. AIM: To present our results of one-stage sex-reassignment surgery in female-to-male transsexuals and to emphasize the advantages of single-stage over multistage surgery. METHODS: During a period of 9 years (2007-2016), 473 patients (mean age = 31...

Urethral defects are normally reconstructed using patient's own genital tissue; however, in severe cases, additional grafts are needed. We studied the suitability of poly(L-lactide-co-ε-caprolactone) (PLCL) and poly(trimethylene carbonate) (PTMC) membranes for urethral reconstruction in vivo. Further, the compatibility of the materials was evaluated in vitro with human urothelial cells (hUC). The attachment and viability of hUCs and the expression of different urothelial cell markers (Cytokeratin 7, 8, 19 and Uroplakin Ia, Ib and III) were studied after in vitro cell culture on PLCL and PTMC...

The free radial forearm flap is considered as the gold standard in penile reconstruction for good functional and aesthetic results. The scar on donor site could be considered as pathognomonic of their situation by transsexual patients. The development of microsurgical flaps provides new therapeutic options. This options are discussed and a therapeutic algorithm is presented. The main techniques used are the pedicled anterolateral thigh perforator flap and free muscle sparing latissimus dorsi flap. Principal criteria are listed, the choice of patient and the local anatomical conditions are the most important...
