Laparoscopy-assisted ureterostomy— techniqueUrinary tract anomalies in children at times pose challenges in which immediate urinary diversion is required before definitive reconstruction. Open cutaneous ureterostomy technique is a well-established approach for this scenario. We describe the laparoscopy-assisted alternative.
Laparoscopic posterior appendix Mitrofanoff using the modified Shanfield anastomosisLaparoscopic transperitoneal technique for appendicovesicostomy was performed in a 5-year-old boy with a non-neurogenic neuropathic bladder using a transumbilical 5-mm port, two 3-mm working ports and a modified Shanfield anastomosis. Posterior extramucosal detrusorotomy and submucosal dissection was performed. The proximal appendix was spatulated and advanced into the bladder through a mucosal window using a U-stitch and fixed. The detrusor was then approximated creating an antirefluxing extramucosal tunnel.
External stent in laparoscopic pyeloplasty: The K-wire techniqueThe majority of surgeons leave internal stents following laparoscopic pyeloplasty, which necessitates a second anaesthetic for removal. A novel technique of placing external nephro-ureteric stents, thus obviating a second procedure for retrieval, is shown in this video bank. As demonstrated in the video, a Kirschner wire (K-wire) is used to thread the stent in place. Although, there are few reports of using externalised stents in laparoscopic pyeloplasty, it is believed that this technique has not been previously described.
