Robot-assisted radical nephroureterectomy for right renal pelvic tumor post sacrocolpopexy with mesh: A case report

Introduction: Robot -assisted nephroureterectomy for upper tract urothelial carcinoma has been increasingly performed as a minimally invasive procedure recently. However, there are concerns regarding its adoption in highly complex cases with dense adhesions. Presentation of case: An 86 -year -old woman presented to our hospital with gross hematuria one year after having undergone robot -assisted sacrocolpopexy using a mesh for pelvic organ prolapse. Cystoscopy revealed hematuria from the right ureteral orifice. Computed tomography suggested right hydronephrosis; retrograde pyelography showed a defect in the right renal pelvis with class V urine cytology of the urine from the right kidney. Based on these findings, a right renal pelvic tumor was diagnosed, and robot -assisted nephroureterectomy was performed. The patient was discharged on postoperative day 7 without complications. Discussion: To the best of our knowledge, this is the first case report in which robot -assisted radical nephroureterectomy was performed after robot -assisted sacrocolpopexy with a mesh. Dense tissue adhesions are encountered not only between the bladder and the anterior vaginal wall but also around the right ureter in the pelvis. In this case, dense adhesions were confirmed around the right ureter in the pelvis. Conclusion: Robot -assisted nephroureterectomy may be considered an option for minimally invasive surgery in cases with a history of pelvic organ prolapse surgery using mesh.
