Seventeen cases of a solitary polyp of posterior urethra in children (ages ranged between 4 months and 12 years) are presented. All patients were treated endoscopically using a 10 Fr. pediatric cystoscope, equipped with a straight ahead lens, and a Bugbee 3 Fr. electrode to fulgurate the stalk of the polyp through the urethra, without meatotomy. No(More)
In the female adrenogenital syndrome, the treatment of the urogenital sinus with high implanted vagina still presents a surgical challenge. The conventional technique (perineal vaginal pull-through) has been plagued by a high incidence of vaginal stenosis. A posterior sagittal transanorectal approach was proposed as an alternative to obtain an excellent(More)
PURPOSE Female gender has been assigned to 46,XY newborns affected by aphallia, possibly resulting in subsequent gender dysphoria. Prenatal and postnatal effects of the androgens on the brain and sexual orientation cannot be modified later. Therefore, patients affected by aphallia should be raised as males. Because definitive forearm flap phalloplasty is(More)
OBJECTIVE To determine whether bladder augmentation has a role in avoiding urinary diversion in patients with exstrophy-epispadias complex (EEC), whether it can improve the lifestyle in patients who have previously undergone diversion or improve the result of any single surgical step in the staged functional reconstruction of the bladder in these patients.(More)
PURPOSE The nephropathy associated with vesicoureteral reflux (VUR) is one of the leading causes of chronic renal failure (CRF) in children. We describe the clinical course of the disease based on information available in the ItalKid Project database, and analyze the predictive value of baseline renal function, age at VUR diagnosis and urinary protein(More)
We performed routine neonatal ultrasound screening on 3,454 neonates in the first week of life to establish the real incidence of congenital uropathy. Pronounced anomalies were found in 36 cases (1.04%) and mild renal pelvis dilatation in 159 (4.60%). In the population study prenatal ultrasonography showed evidence of severe anomalies in only 7 fetuses(More)
To evaluate the age and mode of presentation of patients with posterior urethral valves (PVU) in the antenatal and postnatal periods, we analyzed the files of 108 patients with the diagnosis of PUV in four referral hospitals in Riyadh, Saudi Arabia from 1989 to 1999. Of the study patients, 29 (27%) were antenatally discovered, 41 (38%) in the first year of(More)
PURPOSE We report a 9-year experience with successful treatment of patients with vaginal atresia at a missionary hospital with decreased facilities in Bangladesh. MATERIALS AND METHODS From 1995 to 2002, 20 patients 10 to 29 years old (average age 18.4) with Mayer-Rokitansky-Kuster-Hauser syndrome underwent total vaginal replacement. Ten of the 20 females(More)
PURPOSE Surgical access to the posterior urethra is often difficult and several surgical solutions have been proposed. We suggest an anterior sagittal transanorectal approach based on splitting the anterior rectal wall only. This alternative technique provides excellent exposure to the retrourethral region, permitting simple and safe surgery. MATERIALS(More)
OBJECTIVE To evaluate the prevalence of latex sensitization in a group of patients with bladder exstrophy, and to determine the role of associated risk factors, e.g. atopy, and the number and duration of surgical and anaesthetic procedures. PATIENTS AND METHODS The study comprised 17 patients (15 children and two young adults) affected by bladder(More)
