OBJECTIVE To describe the sonographic visualization of fetal micturition and its role in the diagnosis of posterior urethral valves and hypospadias. METHODS This was a prospective study of 25 male fetuses (21 with bilateral pyelectasis, one whose bladder was being studied because of ureterocele and three with hypospadias), and five female fetuses (with bilateral pyelectasis). A midline sagitt...

BACKGROUND The management of urethral stricture is a challenge to both the urologists and the patients. Thoughtful and satisfactory preoperative evaluation remains important to achieving good outcome. Retrograde urethrography and Micturating Cystourethrography (RUG/MCUG) have been the gold standard imaging technique in the evaluation of anterior urethral stricture but are not without inherent l...

OBJECTIVE Fetal intervention for obstructive uropathy was first performed at the University of California, San Francisco in 1981. Indications for treatment were bilateral hydronephrosis with oligohydramnios. Preintervention criteria included fetal urinary electrolytes with beta-microglobulin levels, karyotyping, and detailed sonography specifically looking for renal cortical cysts. We reviewed ...

BACKGROUND Anterior urethral stricture remains a great challenge. We reported our clinical technique and results by using inlay dorsal buccal mucosal graft urethroplasty for repair of anterior urethral stricture. METHODS From January 2005 to July 2008, 87 male patients (range from 9 to 72 years old) with anterior urethral stricture have been treated by one-stage dorsal inlay oral mucosal graf...

OBJECTIVES Although valve ablation is the treatment of choice for patients with posterior urethral valves, debate continues as to the role of urinary diversion. We sought to retrospectively compare the clinical and radiologic outcomes between valve ablation and urinary diversion for patients with posterior urethral valves. METHODS We retrospectively reviewed the records of 50 consecutive pati...
