Urethral stricture disease continues to be a common problem for patients and urologists alike. Endoscopic treatment offers a simple, potentially effective treatment of primary, short, urethral strictures. For patients who recur after endoscopic management, urethral or bladder neck reconstruction should be offered with an experienced urologic reconstructionist familiar with the complexity of the situation and subtleties of the surgery. With the advent of adjunctive antifibrotic agents the durability of endoscopic repair seems to improve, but their use requires continued research and longer follow-up to determine their efficacy...

In recent years, the issues of the transgender population have become more visible in the media worldwide. Transgender patients at various stages of their transformation will present to urologic clinics requiring general or specialized urologic care. Knowledge of specifics of reconstructed anatomy and potential unique complications of the reconstruction will become important in providing urologic care to these patients. In this article, we have concentrated on describing diagnosis and treatment of the more common urologic complications after female-to-male reconstructions: urethrocutaneous fistulae, neourethral strictures, and symptomatic persistent vaginal cavities...

INTRODUCTION: Within the veterinary world, data regarding the surgical management of hypospadias is lacking. Reports within equines have documented resective phallectomy procedures rather than urethral reconstruction. This case report documents the first ever urethroplasty for an equine hypospadias, performed by a consultant paediatric surgeon. The urethroplasty was achieved by applying the same surgical principles mastered from paediatric urology to a horse. The indication for surgery was contact dermatitis of the hind-leg, which impaired the thoroughbred foal's racing potential...

BACKGROUND: Total cystectomy and subsequent reconstruction of the urinary tract may be required for primary malignancy of the bladder, or in the context of multi-visceral resection for more advanced pelvic tumors. Complications following urinary diversion are a major source of morbidity, particularly in pelvic exenteration (PE) patients. METHODS: All patients who underwent radical cystectomy alone or during PE at a single tertiary referral centre between 2008 and 2014 were reviewed...

Organ models are used for planning and simulation of operations, developing new surgical instruments, and training purposes. There is a substantial demand for in vitro organ phantoms, especially in urological surgery. Animal models and existing simulator systems poorly mimic the detailed morphology and the physical properties of human organs. In this paper, we report a novel fabrication process to make a human kidney phantom with realistic anatomical structures and physical properties. The detailed anatomical structure was directly acquired from high resolution CT data sets of human cadaveric kidneys...

INTRODUCTION: Congenital anterior urethral diverticula in adult males are infrequent urological diseases, which they were mainly found in women. The etiology of female diverticula is that (Mohan et al. in J Urol 123(4):592-594, 1980) women have anatomically poorly supported urethral. Clinical presentation frequently involves urinary urgency, polyuria, postmicturition dribble, and hematuria. CASE DESCRIPTION: A 37 year-old male was presented to us complaining of infertility about 6 years after marriage...

PURPOSE: Urethral strictures are a common disease of the lower urinary tract in men. At present, the use of buccal mucosa is the method of choice for long or recurrent strictures. However, autologous tissue-engineered grafts are still under investigation for reconstructive urological surgery. The aim of this pilot study was to evaluate the use of human urothelial cells (HUC) seeded on bovine collagen type I-based cell carriers (CCC) in an animal model and to evaluate short-term outcome of the surgical procedure...

OBJECTIVE AND INTRODUCTION: Cowper's syringocele is a cystic dilation of the bulbourethral gland duct, initially defined by Maizels et al. in 1983. Although obstructive and non-obstructive types of this rare anomaly are described, clinical symptoms are highly unspecific. Therefore, we report 12 cases of children and young adults diagnosed with Cowper's syringocele to further clarify clinical course, comorbidity and treatment strategies. STUDY DESIGN: We retrospectively collected clinical data of 12 children and young adults from birth to 18...

Hypospadias is a congenital anomaly of the male urethra that causes significant morbidity in the pediatric male population. The mainstay of treatment is hypospadias repair surgery. However, given the common co-occurrence of microphallus in these patients, surgery remains difficult without adequate tissue for proper reconstruction of the urethra. The use of preoperative testosterone therapy, parenterally or topically, has been a topic of study for several years in urologic literature. This literature review aims to summarize the different studies that have been conducted to address whether preoperative testosterone therapy is beneficial, inconsequential, or detrimental to the surgical and cosmetic outcomes of hypospadias repair as well as to address the differences in routes of administration...

PURPOSE: Rectourethral fistula is a known complication of prostate cancer treatment. Reports in the literature on rectourethral fistula repair technique and outcomes are limited to single institution series. We examined the variations in technique and outcomes of rectourethral fistula repair in a multi-institutional setting. MATERIALS AND METHODS: We retrospectively identified patients who underwent rectourethral fistula repair after prostate cancer treatment at 1 of 4 large volume reconstructive urology centers, including University of California-San Francisco, University College London Hospitals, Lahey Clinic and Devine-Jordan Center for Reconstructive Surgery, in a 15-year period...

OBJECTIVE: To identify risk factors for urologic reconstruction during surgery for endometriosis PATIENTS AND METHODS: We retrospectively identified patients in a surgical pathology database undergoing surgery for endometriosis at our institution from 2010-2015 and subsequently identified those patients with ureteral involvement. Patients were categorized as requiring minimal urologic surgery (e.g. ureterolysis only) or more extensive urologic surgery (e.g. ureteral reimplant). All patients were undergoing surgery for endometriosis, and preoperative risk factors were then identified to predict the need for intraoperative extensive urologic surgery...

INTRODUCTION: Robotic technology has been increasingly utilized for complicated reconstructive surgeries in pediatric urology, such as ureteroureterostomy (UU). The literature is limited regarding the performance of minimally invasive UU in children, and the existing published series utilize indwelling ureteral stents. We sought to report on our pediatric experience with robot-assisted laparoscopic (RAL)-UU using a temporary ureteral catheter in duplex systems with ureteral ectopia. METHODS: A retrospective chart review was performed of all pediatric patients who underwent RAL-UU at a single institution over a 2-year period...

INTRODUCTION AND HYPOTHESIS: We compared persistence on overactive bladder (OAB) pharmacotherapy in patients treated in the Female Pelvic Medicine and Reconstructive Surgery (FPMRS) department compared with patients treated in the Internal Medicine (IM) and General Urology (GU) departments within an integrated health-care system. We hypothesized that persistence would be higher among FPMRS patients. METHODS: This was a retrospective cohort study. Patients with at least one prescription for OAB between January 2003 and July 2014 were identified...
