PURPOSE We clarified the long-term effects of extracorporeal shock wave lithotripsy on renal function and blood pressure, and its relation to body mass index and type of lithotriptor. MATERIALS AND METHODS A total of 100 patients with a single radiopaque renal stone 2 cm or less in length were followed for 18 to 57 months (mean 43.6 +/- 13.8) after being(More)
PURPOSE Staging of childhood renal tumors is crucial for treatment planning and outcome prediction. We sought to identify whether computerized tomography could accurately predict the local stage of childhood renal tumors. MATERIALS AND METHODS We retrospectively reviewed our database for patients diagnosed with childhood renal tumors and treated(More)
OBJECTIVES We report our experience in the management of urethrorectal fistulae in children with emphasis on the complexity of this rare disease. PATIENTS AND METHODS A retrospective review was performed in cases that underwent repair of urethrorectal fistula at our center between 1997 and 2007. Records were reviewed for age, history, presentation,(More)
OBJECTIVE To asses the efficacy and safety of bidirectional synchronous twin-pulse extracorporeal shock wave lithotripsy (ESWL) compared with standard ESWL. PATIENTS AND METHODS Between March 2003 and December 2006, 240 patients with a radio-opaque single renal stone of <or=25 mm were randomized to treatment either by the Twinheads (TH) lithotripter (FMD,(More)
PURPOSE To evaluate the outcome of secondary surgical procedures for the management of failed pyeloplasty in children. MATERIALS AND METHODS Between 1996 and 2007, 590 cases of primary ureteropelvic junction (UPJ) obstruction underwent open dismembered pyeloplasty at our center. Of these patients, 18 (3%) with recurrent UPJ obstruction (14 males, 4(More)
AIMS Post-exstrophy incontinence is a challenge because continence is difficult to achieve and more difficult to maintain. Feasibility and outcomes of a bulbourethral sling to treat post-exstrophy incontinence is shown in this report. METHODS A retropubic bulbourethral sling was applied to male patients with incontinence post-exstrophy-epispadius repair.(More)
PURPOSE To review our experience of tubularized incised plate (TIP) urethroplasty in children with hypospadias defects. METHODS Of 500 children (mean age 6 years) who received a TIP urethroplasty, 439 (87.8%) had primary hypospadias and 61 had one failed previous repair. The hypospadias defects were coronal in 110 (22%), distal penile in 261 (52.2%),(More)
Cloacal duplication is an exceedingly rare group of anomalies with a limited number of cases reported so far. The anomaly may be confined to partial bladder duplication or it may involve complete duplication of the urogenital tract, hindgut, spine, lower limbs, and vascular structures. Every case is unique and ought to be approached individually. By means(More)
Bladder neck closure (BNC) is the ultimate bladder neck reconstruction. If reconstruction fails, closure must be considered as it gives the highest continence rate. The vast majority of BNCs are performed through an abdominal approach (either transvesical or extravesical approach), but perineal approach remains an option for BNC with considerable success(More)
