The incidence of urethral stricture and bladder neck contracture with transurethral resection vs. holmium laser enucleation of prostate: A matched, dual-center study.

Introduction: Urethral strictures (US) and bladder neck contracture (BNC) are common, long-term complications of transurethral prostate surgery. We aimed to compare transurethral resection of the prostate (TURP) and holmium laser enucleation of the prostate (HoLEP) regarding incidence of US or BNC and identify possible risk factors.

Methods: A retrospective review of patients who underwent TURP and HoLEP with followup data of at least one year in two separate institutions was performed.

Role of tadalafil in enhancing visualization of posterior urethra prior to combined voiding cystourethrogram and retrograde urethrogram: a retrospective analysis.

Purpose: To show utility of tadalafil in enhancing visualization of posterior urethra in patients with urethral stricture.

Methods: We retrospectively reviewed the records of adults male who failed to delineate the posterior urethra while undergoing combined voiding cystourethrogram and retrograde urethrogram (VCUG and RUG), as a part of preoperative assessment of stricture length and location before urethral reconstruction. The study was repeated 24 h later after a single dose of tadalafil 20 mg was administrated 2 h before the procedure (Tadalafil group).

Biofabrication and biomaterials for urinary tract reconstruction.

Reconstructive urologists are constantly facing diverse and complex pathologies that require structural and functional restoration of urinary organs. There is always a demand for a biocompatible material to repair or substitute the urinary tract instead of using patient's autologous tissues with its associated morbidity. Biomimetic approaches are tissue-engineering tactics aiming to tailor the material physical and biological properties to behave physiologically similar to the urinary system.
