Combined use of percutaneous and transurethral instruments in the preadolescent children with intravesical pathologies.

The approach for the intravesical suspicious lesions or stones in the preadolescent children especially in boys is still a challenging problem. Open surgery, percutaneous suprapubic endoscopy or transurethral endoscopic approaches are the treatments of choice in children. However, there is a group in children between the ages of 10 and 12 years, which can be named as grey zone population; the length of the instruments is insufficient for transurethral intervention such as endoscopic stone extraction, transurethral bladder tumor resection especially for the lesion at the posterior bladder wall in this group. The aim of this study is to describe a new technique using laparoscopic instruments for percutaneous bladder stone and tumoral lesion and determines the efficacy of this procedure. Satisfactory results have been obtained in patients with these pathologies. In selected cases, operation time, urethral and mucosal damage, hospital stay, and cost can be decreased to a minimum with this simple technique.
