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)
OBJECTIVE Complex hypospadia repair can be performed according to different strategies, mostly in one or two stages. We present a detailed video of one patient operated according to the three-in-one technique, which combines dorsal buccal mucosa grafting for reconstruction of the incised urethral plate and a preputial flap onlay urethroplasty covered by a(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 evaluate the role of elective appendicovesicostomy in association with Monfort abdominoplasty to avoid urinary tract infection (UTI) and renal damage in the post-operative follow-up of patients with prune belly syndrome. MATERIALS AND METHODS We followed 4 patients operated in our institution (UNIFESP) (Monfort, orchidopexy and Mitrofanoff)(More)
OBJECTIVE Aphallia is a rare penile congenital abnormality. The aim of this systematic review was to assess all available literature on neophalloplasty in infancy with an interest in technical alternatives and clinical outcome. MATERIALS AND METHODS We performed a Pubmed search using the terms: neophalloplasty, neophallus, and phalloplasty, and selected(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)
OBJECTIVE To evaluate, in an experimental study in rabbits, a new model of neophalloplasty based on two lower abdominal skin flaps and ventral buccal mucosa graft for planned two-stage urethroplasty procedure. MATERIAL AND METHODS Sixteen rabbits were operated and divided into four equal groups which were sacrificed at 2, 4, 8 and 12 weeks. The(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 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)
