OBJECTIVE: To describe a novel, minimally invasive surgical technique, robotic-assisted laparoscopic dismembered extravesical cross-trigonal ureteral reimplantation for primary obstructive megaureter and to report a case series of 13 patients.
METHODS: Thirteen patients between the ages of 10 and 96 months who were diagnosed with primary obstructive megaureter underwent robotic-assisted laparoscopic dismembered extravesical cross-trigonal ureteral reimplantation between April 2017 and May 2019. The principle of this technique is performing an extravesical cross-trigonal ureteral reimplantation with intracorporeal tailoring of the ureter. This provides the advantage of achieving a long tunnel mimicking the Cohen cross-trigonal ureteral reimplantation, without performing the open surgical technique and offers the potential benefits of minimally invasive surgery. Surgical technique is described, demographic data and intra- and/or postoperative parameters are reported.
RESULTS: Median age was 26 months (IQR 16-60). Median weight was 15 kg (IQR 10.1-31). Median console time was 113 minutes (IQR 90.5-140). Median postoperative stay was 2.5 days (IQR 1.3-3). Median ureteral diameter decreased from 17 mm (IQR 12.5-18.5) to 3 mm (IQR 0-6.5, P = .001). Median renal pelvis diameter decreased from 28 mm (IQR 20.5-37.8) to 4 mm (IQR 1.5-5, P = .005). Median renal function before surgery was 46% (IQR 24.5-48.5) and following surgery was 42% (IQR 36-42, P = .700). Median T1/2 decreased from 28 minutes (IQR 19.3-30) to 4.5 minutes (IQR 3-5, P = .009). Postoperative complications graded by the Clavien-Dindo classification were apparent in 3 patients (21%). One had grade I complication (fever, resolved spontaneously) and 2 had a Grade II complication (urinary tract infection).
CONCLUSION: Robot-assisted cross-trigonal ureteral reimplantation with intracorporeal tailoring is safe, feasible, and reproducible in short-term follow-up.
