External stent in laparoscopic pyeloplasty: The K-wire technique

The 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. So far this technique has been used in 22 patients without any stent-related complications. The technique is feasible, safe and reproducible. It obviates the need for a further anaesthetic and avoids potential risks of another procedure. Secondary benefits include avoiding another hospital admission.
