The robotic approach for ureteral reconstruction has been widely popularized due to patient advantages that come with minimally invasive surgery, surgeon ergonomics, and reproducibility with outcomes comparable to that of open or laparoscopic surgery. While well-established reconstructive procedures such as pyeloplasty, ureteral reimplantation, and...
Objectives
To compare the perioperative and postoperative outcomes of single port robotic pyeloplasty and multiport robotic pyeloplasty using a propensity-score matched analysis.
Materials and Methods
We performed a chart review of all patients who underwent single port robotic pyeloplasty from January 2019 to October 2020 and multiport robotic py...
Ureterolysis is the release of the ureter from its surrounding compressive fibrotic tissue. It is required in the setting of extrinsic compression from retroperitoneal disease processes, including idiopathic retroperitoneal fibrosis, lymphoma, infection, or scarring from previous surgery. Boari flap ureteral reimplantation is a reconstructive proce...
Objectives
To evaluate the effect of ureteral rest on outcomes of robotic ureteral reconstruction.
Methods
We retrospectively reviewed all patients who underwent robotic ureteral reconstruction of proximal and/or middle ureteral strictures in our multi-institutional database between 2/2012—03/2019 with ≥12 months follow-up. All patients were recom...
Omental wrap is commonly performed after ureterolysis to prevent ureteral obstruction from recurrence of periureteral adhesions and fibrosis. We present the case of a 37-year-old Caucasian woman with a history of two cesarean sections and laparotomy for the treatment of endometriosis. She subsequently developed right flank pain caused by a right di...
Objectives:
To report our multi-institutional, comprehensive experience with robotic ureteral reconstruction (RUR) in patients with radiation-induced ureteral stricture (RIUS).
Patients & methods:
In a retrospective review of our multi-institutional robotic reconstruction database between January 2013 to January 2020, we identified patients with...
Objectives
To update our prior multi-institutional experience with robotic ureteroplasty with buccal mucosa graft and analyze our intermediate-term outcomes. Although our previous multi-institutional report provided significant insight into the safety and efficacy associated with robotic ureteroplasty with buccal mucosa graft, it was limited by sma...
OBJECTIVES
To describe surgical techniques and peri-operative outcomes with secondary robotic pyeloplasty (RP), and compare them to those of primary RP.
METHODS
We retrospectively reviewed our multi-institutional, Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database for all consecutive patients who underwent RP between 04/201...

... For either anxiety or depression, the total score ranges from 0 to 21. In this study, the anxiety/depression scores of HADS were further divided into four cases: non-anxiety/depression case (0-7), mild case (8-10), moderate case (11)(12)(13)(14), and severe case (15)(16)(17)(18)(19)(20)(21) [11]. For the Chinese version of the HADS, it was reported that Cronbach's alpha was 0.86 for the full scale, 0.77 for the anxiety subscale, and 0.82 for the depression subscale [12]. ...

... Multiple examples of success with the appendiceal interposition technique have been described in treating traumatic ureteral injury, radiation-induced stricture disease, obliterative stricture disease, and pediatric stricture disease (18)(19)(20)(21)(22)(23). In 2000, Richter and colleagues performed an appendiceal interposition to replace the ureter in three children. ...

... Although data from retrospective series regarding ureteral reconstruction surgery in this setting have been favourable, most reports focus solely on outcomes of secondary pyeloplasty for management of recurrent ureteropelvic junction obstruction (UPJO). [4][5][6][7][8][9][10][11] There are insufficient data surrounding the use of reconstructive techniques for recurrent strictures in the proximal, middle or distal ureter. 12,13 Herein, we describe peri-operative outcomes of patients undergoing robotic ureteral reconstruction (RUR) for management of recurrent ureteral strictures after prior failed endoscopic and/or surgical intervention. ...
