“…Kocvara, R reported that the operation time of trans-anastomotic externalized stent was significant longer than double-J stent, for uretero-pyelostomy was a more demanding and time-consuming procedure. [ 15 ] Our study also indicates that the duration of operation in TEUS group was significantly longer than that double-J group. This is likely due to the extra need of retrograde urethral stenting in TEUS group.…”

“…Other types of externalized stents had been attempted in laparoscopic pyeloplasty, most of them adopt trans-pelvic route. Compared with double-J stents, externalized stents had fewer complications and fewer re-operation patients [ 8 , 15 , 16 ] (Table 3 ). But urine leakage around the tube and patient discomfort surrounding the tube entry site could not be avoided, in TEUS, insertion through natural orifices with minimum tissue damage could avoid the disturbance.…”

“…Similar to TEUS, stent dislocation should be concerned throughout the perioperative period in externalized stents. With improved experience, we could shorten the time to stent removal to 5 days in 15 children with fair recovery, compared with the reported time of stent removal in externalized stents, [ 8 , 15 ] we are the shortest 1 could reduce the risk of stent dislocation.…”

Purpose: We present a new approach for urine drainage in pediatric patients following laparoscopic pyeloplasty, the trans-uretero-cystic external urethral stent (TEUS). Methods: We retrospectively identified 85 children who underwent laparoscopic pyeloplasty from July 2015 to June 2017. The included children were assigned to group A (double-J stent) or group B (TEUS). In group A, the double-J stent was removed by a cystoscopy under anesthesia after 1 month, while in group B, the external stent was removed after 5 to 7 days. We examined the durations of operation, hospital stay and the frequency of stent-related complications including urinary leakage, stent dislocation, stent occlusion, and urinary tract infection. Results: The operation time was significantly longer for patients in group B than for those in group A. No significant difference was observed between the groups regarding stent-related complications. In group A, 4 patients need auxiliary stent re-insertion for the management of complications, 2 developed urinary tract infection, and 2 had stent occlusion. In group B, none needed auxiliary stent re-insertion for complications and avoided re-operation. Conclusions: In children, the outcome of external stent implantation was similar to that using double-J stent, and the use of the former approach may be beneficial for younger children.

“…The question of whether to stent or not routinely following pyeloplasty is another area of controversy and a clear consensus does not exist 21,22 . Proposed advantages of using a stent are that it helps to maintain the alignment of the anastomosis and minimizes extravasation of urine caused by the transient obstruction to flow due to surgical oedema.…”

“…However, stenting has its own complications such as increased infection rates, stent migration, strictures and prolonged hospital stay. Furthermore, a second general anaesthetic is required for removal of the stent 20,21 .…”
