Background: Posterior urethral valves (PUVs) represent the most common cause of male congenital lower urinary tract obstruction, often responsible for renal dysplasia and chronic renal failure. Despite recent improvements in patients' outcomes thanks to prenatal ultrasound early diagnosis, PUVs can still impact sexual function and fertility. This study aims to review the available evidence on fertility in PUV patients, examining paternity rates and semen parameters.

Article Synopsis
  • Patients with penile defects, whether congenital or acquired, experience significant psychological distress, and the free radial artery forearm flap method has emerged as a preferred technique for reconstruction.
  • A retrospective study over 16 years reviewed various cases, modifying the initial design to enhance urethral function and stability in the procedure.
  • Results indicated that most patients regained sensation and could urinate standing; however, some experienced complications, and aesthetic outcomes varied, highlighting the technique's potential for effective rehabilitation.

Introduction: Posterior urethral valve (PUV) is a congenital condition marked by obstructing persistent urogenital membrane, leading to urinary tract infections, bladder dysfunction, and kidney damage. It affects males only, mostly suspected antenatally and confirmed in early infancy. It requires early diagnosis and intervention to prevent long-term complications.

Introduction: Posterior Urethral Valves (PUV) are rare congenital anomalies of the male urinary tract that can lead to urethral obstruction and increased risk of kidney disease. Traditional diagnosis relies on subjective interpretation of imaging techniques. This study aimed to automate and increase accuracy of PUV detection in voiding cystourethrography (VCUG) images using an AI-based pipeline.
