New surgical techniques in pediatric urology

More sophisticated endoscopic instruments, combined with a better understanding of bladder and urethral pathology, have significantly improved the therapeutic approaches for both posterior urethral valves and ureteroceles. New generation lithotripters have allowed for a safe and efficient method of treating urinary calculi in children, which was once thought too injurious a process with first-generation machines. The rapidly advancing field of laparoscopy, aided by the development of more optically refined and diminutive instruments, has allowed for its application in a wide variety of surgical interventions in pediatric urology. The tubularized incised plate urethroplasty has challenged more traditional approaches to hypospadias repair and is now considered by many pediatric urologists to be the best approach for midshaft and distal hypospadias. The one-stage approach to exstrophy repair may hold the answer to improved continence without a formal bladder neck reconstruction. Finally, the field of tissue engineering leads the way to new advances in autologous biological substitutes in the surgically-challenged patient where there is a shortage of local tissues at the surgeonʼs disposal.
