Introduction

To investigate the feasibility of single port (SP) robotic retroperitoneal(RP) nephroureterectomy(NUx) with bladder cuff excision.

Materials

We sequentially analyzed 20 patients who were performed SP robot NUx from January 2021 to December 2022. All patients were diagnosed with upper tract urothelial carcinoma (UTUC) and were operated by a single expert with da Vinci SP platform.

Results

,

Total of 20 patients underwent SP robotic NUx with bladder cuff excision. The mean age of the patients was 69.45 ± 8.68 years, and the mean body mass index (BMI) was 25.37 ± 3.00 kg/m². The mean tumor size was 2.42 ± 1.03 cm on CT scan, with right tumors in 8 patients (40%) and left tumors in 12 patients (60%).  The median console time was 106 minutes 40 seconds and the expected blood loss was 122.50 ±75.18 ml. Final pathology showed all of patients diagnosed as urothelial carcinoma and 1 was Ta (5.00%), 3 were T1(15.00%), 7 were T2(35.00%), 8 were T3(40.00%) and 1 was T4(5.00%). None of the 20 patients showed complications with Clavien-Dindo scale.

Conclusion

SP robotic NUx via with retroperitoneal approach offers feasible perioperative and postoperative outcomes for UTUC.
