Reconstructive Group

The YAU Trauma and Reconstructive Urology Working Party currently includes 10 members of different expertise in the broad field of Reconstructive Urology; e.g. urethroplasty, trauma surgery, incontinence surgery, fistula repair, ureteral repair, pyeloplasty, penile reconstructive surgery, corporoplasty, urinary diversion, transgender surgery, 3D modelling, tissue engineering, robotic surgery, andrology, and sexual medicine. We embrace the heterogeneity and diversity of our group, which widens the spectrum of research interest and allows views from different angles on each project, as you can see below.

Aims of our working party

Our YAU group was founded in March 2017 and thus, is the ‘youngest’ together with the Urotech group. Embodying the main principles of the YAU, we aim to provide evidence-based medicine, specifically into the field of Reconstructive Urology and urethroplasty, for which (EAU) guidelines-based recommendations have been published not until spring 2021 for the first time.

  • One of our main projects is merging already existing retrospective institutional databases and create prospective multi-institutional registries. Based on these datasets, we develop new risk models on different surgical outcomes and validate Patient-Reported Outcome Measures (PROMs) for urethral stricture disease
  • Our group actively supports the new upcoming EAU Guidelines Section on urethral stricture disease by providing systematic reviews and meta-analyses on topics which lack evidence
  • Within the EAU, we collaborate with different institutions such as European School of Urology (ESU) and European Society of Genital Urinary Reconstructive Surgeons (ESGURS). We believe in the importance for international collaborations with already formed research groups such as the American Trauma Urologic Reconstructive Network Surgeons (TURNS) and The European Society of Sexual Medicine (ESSM) Scientific Collaboration and Partnership (ESCAP) to create high-quality projects
  • Furthermore, our group initiates collaborative projects with other YAU working groups; e.g. a special edition on sequelae of prostate cancer therapy: avoidance strategies and management options, which includes the Prostate Cancer, Functional, Robotic, Men’s Health and Trauma and Reconstructive Urology Working Parties.

Finally, we invite academic practicing urologists in Europe with a major interest in trauma and reconstructive urology to actively collaborate and thereby creating a group of young “key opinion leaders” in the field of trauma and reconstructive urology in Europe.

Ongoing projects and plans for the future

Retrospective, prospective and randomized controlled trials, surveys and fellowship programs

  • ESGURS Survey on urethral stricture practices
  • Collaborative multi-institutional European urethroplasty database of patients who undergo urethroplasty for urethral stricture disease
  • Prospective randomized controlled trial comparing surgical outcomes and donor site morbidity between buccal mucosa and lingual mucosa graft urethroplasty for anterior urethral strictures using the European Association of Urology quality criteria for standardized reporting
  • Prospective randomized controlled trial comparing urethrotomy vs. urethral dilation using sequential dilators for bulbar urethral strictures
  • Prospective study on the main therapy for Peyronie’s disease including the use of all injection’s therapies (including Clostridium collagenase histolyticum) by measuring success, recurrence, shift to surgery and surgical reports. By using Hu-Care trial application (, physicians can enter the data and patients can enter the results, independently, through a specially created app.
  • YAU Andrology Scholarship Program to encourage and support the young urologists to improve their skills and increase their experience in the field of impotence and penile diseases management procedures namely penile Implants and penile reconstructive surgery.
  • (Recurrent) anastomotic strictures to compare Holmium Laser Incision vs cold knife incision in vesicourethral anastomotic stenoses in patients who underwent radical prostatectomy for prostate cancer (prospective multi-institutional study)
  • Primary urethral realignment vs suprapubic catheter for posterior urethral (traumatic) injuries (retrospective multi-institutional study)
  • Long-term follow-up for patients operated by paediatric surgeons for distal hypospadias (retrospective study)
  • Accuracy of retrograde urethrogram vs. urethral ultrasound in urethral stricture diagnosis and characterization (prospective study)
  • Catheter management and risk stratification in Patients with acute Epididymitis (prospective multi-institutional study)
  • Evaluation of antibiotic treatment, catheter management and risk stratifications in female inpatient suffering from acute cystitis and pyelonephritis (retrospective and prospective multi-institutional study)
  • The impact of preoperative double-J stent on perioperative complications, recurrence and quality of life in adult patients undergoing pyeloplasty (retrospective and prospective multi-institutional study)
  • Participating in prospective DoVe Trial: Dorsal Onlay Versus Ventral Onlay in Isolated Bulbar Urethral Strictures
