An Analysis of Major Causes of Surgical Failure Using Bähren System in Intraoperative Venography During Varicocelectomy.

Purpose: In young patients with varicocele, preservation of the internal spermatic artery may be advantageous for catch-up growth, but it may also increase the likelihood of treatment failure. Intraoperative venography reduces the likelihood that unsealed veins will remain after varicocelectomy. We analyzed the characteristics of remnant veins visualized through intraoperative venography to investigate the cause of surgical failure in artery-sparing varicocelectomy (ASV).

Transurethral incision as initial option in treatment guidelines for ectopic ureteroceles associated with duplex systems.

Purpose: Treatment strategies for children with ectopic ureteroceles (EUs) and duplex collecting systems or vesicoureteral reflux are controversial. Transurethral incision (TUI) of EUs associated with duplex systems has been considered only as a temporizing technique. This study aimed to evaluate whether primary TUIs could be considered as an initial treatment option in EUs with duplex systems.

Efficacy and safety of mirabegron, a β3-adrenoceptor agonist, for treating neurogenic bladder in pediatric patients with spina bifida: a retrospective pilot study.

Purpose: Antimuscarinics are the first pharmacological treatment option for neurogenic bladder in children with spina bifida but side effects limit their use. Mirabegron, a new β-3 adrenoceptor agonist with a distinct mechanism of action, is a potential agent for the treatment of neurogenic bladder; however, it has yet to be studied in the pediatric population. This study evaluated the efficacy and safety of mirabegron for treating neurogenic bladder in children with spina bifida.

The risk factors and clinical significance of acute postoperative complications after unstented pediatric pyeloplasty: a single surgeon's experience.

Purpose: To analyze the risk factors and clinical significance of postoperative complications after unstented pediatric pyeloplasty.

Materials And Methods: We analyzed 285 kidney units (KUs) on which unstented pyeloplasty was performed between April 2002 and March 2010. Measures included preoperative factors, postoperative complications, change in postoperative differential renal function (DRF), and failure of pyeloplasty.

A modified technique for ureteral reimplantation: intravesical detrusorrhaphy.

Purpose: To describe the surgical procedure of intravesical detrusorrhaphy, a modified technique of ureteral reimplantation, and report our initial experience.

Methods: From October 2007 to March 2012, 55 children with vesicoureteral reflux (VUR) and 13 children with obstructive megaureter (OM) underwent intravesical detrusorrhaphy. All surgical procedures were performed via an open intravesical approach.
