Prepubertal testicular tumors: a 20-year experience with 40 cases.

Testicular tumors are rare in children. In addition, prepubertal testicular tumors (PTT) are fundamentally different from their postpubertal counterparts.We reviewed our 20-year experience with 40 cases to suggest an algorithm for the appropriate surgical approach for patients with PTT.

[Dextranomer beads in stabilized non-animal sodium hyaluronate gel (NASHA/Dx gel) for vesicoureteral reflux: multi-center study in Japanease patients].

Purpose: To investigate the efficacy and safety of endoscopic treatment with the injectable gel of dextranomer beads in stabilized non-animal sodium hyaluronate (NASHA/Dx gel) administered submucosally close to the proximity of ureteral orifice, we performed the multi-center open study of Japanese patients with vesicoureteral reflux (VUR). We herein report the results of the study.

Subjects And Methods: Patients aged > or = 1 year with grade II-IV VUR underwent endoscopic injection with NASHA/Dx gel.

Risk factors for breakthrough infection in children with primary vesicoureteral reflux.

Purpose: Despite the widespread application of endoscopic therapy and the debate surrounding the use of prophylactic antibiotics to treat children with vesicoureteral reflux, many pediatric urologists still favor medical management. Breakthrough infection is one of the absolute indications for surgery. Data to predict breakthrough infection are warranted to manage cases of primary reflux.

A new technique of concealed penis repair.

Purpose: Phimosis associated with concealed penis is not amenable to ordinary circumcision. To our knowledge we describe a new technique to repair concealed penis.

Materials And Methods: From September 2003 to January 2008, 57 consecutive patients with concealed penis were treated using our technique.

Renal scarring is associated with nonsecretion of blood type antigen in children with primary vesicoureteral reflux.

Purpose: Nonsecretor status of blood type antigen has been associated with higher risk of urinary tract infection (UTI) in women. However its implication in the modern management for pediatric UTI remains unclear. We evaluate the impact of secretor status on clinical course in children with primary vesicoureteral reflux (VUR).

Biliary atresia with associated complicated anorectal and urogenital malformations.

We report on a girl with biliary atresia (BA) who also suffered with anorectal agenesis without fistula and complicated urogenital malformation. The outcome of patients with these severe anomalies is poor, but she has survived without liver and/or renal transplantation for more than 3 years. A careful treatment plan for each anomaly in addition to prevention of cholangitis and urinary tract infection is indispensable for managing these complicated anomalies.
