Abstract
Purpose
Barbed self-retaining sutures (SRS) have been introduced as an advance in suture technology, facilitating reconstructive laparoscopic surgery. We present the experience of three centers performing laparoscopic pyeloplasty with the use of SRS.
Methods
Preoperative, intraoperative and follow-up data were collected for 6 patients undergoing pyeloplasty using the Quill SRS (Angiotech, Vancouver, CAN) in three centers. Standard laparoscopic pyeloplasty technique was used and a knot-less continuous anastomosis between the spatulated ureter and the renal pelvis was created.
Results
Knot-less uretero-pelvic anastomosis creation was feasible in all six cases. Peri-operative data were similar to standard pyeloplasty using conventional suture materials. A very high stricture recurrence rate (5/6 patients) was noted during follow-up. Further endourologic and open interventions were needed to address the recurrence of the strictures.
Conclusions
Knotless intracorporeal laparoscopic suturing using SRS for the reconstruction of UPJ during laparoscopic pyeloplasty is associated with high rates of stricture recurrence at least in the initial cases of each surgeon. Until further investigations elucidate the cause of treatment failure, SRS should not be recommended for upper urinary tract reconstruction.
