Placement of transurethral urinary drainage catheter using microwire in a newborn with posterior urethral valve: A better alternative to suprapubic catheterization

Abstract

Posterior urethral valves (PUV) present significant challenges in neonatal urinary management, often indicating the use of a suprapubic catheter (SPC). However, complications associated with SPC, coupled with specific contraindications call for alternative approaches. Here, we present a case of successful transurethral catheterization in a 1-day-old premature male infant with PUV, utilizing bedside Ultrasound without anesthesia, effectively alleviating the need for a SPC. The procedure involved careful wire insertion and subsequent catheter placement, facilitating urine drainage, and enabling a micturating cystourethrogram (MCUG) using the same access point. By avoiding SPC-related risks and allowing for essential diagnostic procedures, this approach presents itself as a less invasive and possibly better initial option, particularly in cases where SPC may pose complications. Our findings suggest that ultrasound-guided transurethral catheterization offers a minimally invasive and effective alternative to SPC, proving its potential to enhance patient care and outcomes in challenging PUV cases.
