... However, they did find that those who underwent SP PN had significantly shorter median hospital stay (1.4 days vs 1.6 days, p=0.0045) and lower median opioid use on postoperative day 1 (4.6 MME vs 9.8 MME, p=0.0209). 36 Glaser et al also attempted to establish whether one technique was preferable when they examined 78 patients who underwent either SP PN (26) or MP PN (52). They found no significant differences between the two cohorts in mean operative time, rate of EBL >500 mL, complication rates, rate of discharge on postoperative day 1, or rates of opioid prescriptions being filled. ...
... In reality, the comfort of a large working space and improved visibility still make the transperitoneal approach favorable for most urologists (30). Single-port RARP could be performed in a smaller operating space, which allows it to be performed in extraperitoneal ways more easily (31). Compared with transperitoneal single-port RARP, extraperitoneal singleport RARP is associated with a significantly shorter postoperative hospital stay and decreased need for postoperative narcotics (32). ...

... 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. ...
