PURPOSE We categorized bladder patterns and principles of treatment applied to patients who underwent myelomeningocele repair during gestation in a prospective urological assessment. MATERIALS AND METHODS We performed urinary tract ultrasound, voiding cystourethrogram and urodynamic evaluation. We then categorized patients into 4 patterns, including(More)
PURPOSE To review our clinical experience with urinary continent catheterizable reservoir in children under five years of age. MATERIALS AND METHODS A total of 23 patients (16 males, 7 females) with a median age of 3.64 years were evaluated. Among these, 6 (26.08%) had a posterior urethral valve, 9 (39.13%) myelomeningocele, 4 (17.39%) bladder exstrophy,(More)
INTRODUCTION Urethral duplication is a rare congenital anomaly affecting mainly boys. Generally, the duplication develops on the sagittal plane; the accessory urethra may run dorsally or ventrally to the orthotopic one. We present a patient with urethral duplication in which the orthotopic urethra was patent in the penile segment but atresic in the bulbar(More)
A case of bladder hemangiomas in association with Proteus syndrome (PS) is described. PS is a rare hamartomatous disorder and comprises an association of verrucous epidermal nevi, infantile hemangiomas, lipoma-like subcutaneous hamartomas and asymmetrical overgrowth of almost any part of the body. To our knowledge, this is the second case reported of(More)
PURPOSE Complex primary hypospadias repair that warrants urethral plate division is treated mostly in two steps, not necessarily in two surgeries. Our aim was to review long-term results with a one-stage strategy based on reconstruction of the urethral plate with buccal mucosa graft and onlay transverse preputial flap anastomosis protected by a tunica(More)
PURPOSE We investigated continence outcomes for patients undergoing primary or redo reconstruction of a urinary catheterizable reservoir involving the Yachia technique of intersecting two rectus abdominis strips over the outlet channel. MATERIALS AND METHODS A retrospective evaluation of 22 consecutive patients operated from March 2009 to August 2010 was(More)
PURPOSE Premature delivery is a major complication of in utero myelomeningocele repair. The prematurity rate in MOMS (Management of Myelomeningocele Study) was 79%, with a mean gestational age at birth of 34 weeks. We speculated that prematurity could also influence urological outcome in patients operated on prenatally for myelomeningocele. MATERIALS AND(More)
OBJECTIVE To demonstrate ventral corporoplasty, with tunica vaginalis flap to reconstruct the corpora cavernosa, in a two-stage strategy for proximal hypospadias surgery. METHODS Assessment of residual curvature after complete urethral plate division and transverse superficial cuts in albuginea. Ventral incision of tunica albuginea to elongate the ventral(More)
OBJECTIVE The Mitrofanoff principle is a well established strategy in pediatric urology, with the appendix and Yang-Monti tube being the most used channels. The search for an alternative tube with less morbidity is justified. Hence, we present a patient treated via an alternative approach in which the channel was constructed from two lower abdominal(More)
