Minimally invasive surgery for pelviureteral junction obstruction in adults: A critical review of the options

Endourologic techniques for ureteropelvic junction obstruction therapy. Comparative animal study

“…Endopyelotomy is based on the concept that healing of the incised ureter occurs in a nonobstructing fashion around an indwelling stent usually of standard size [20]. The difference between the 2 techniques was probably because the Acucise produces an endopyelotomy with a predetermined direction and length unlike rupture with the balloon that leads to a ureteral tear [15].…”

“…Laparoscopic pyeloplasty is the most invasive therapeutic option available in endourology and must be reserved only for patients in which the Acucise endopyelotomy is not recommended (pelvis volumes of more than 70 mL, renal function of less than 30%, or who have a crossing vessel) [20,26].…”

Hydronephrosis in the course of ureteropelvic junction obstruction - an underestimated problem?Current opinion on pathogenesis, diagnosis and treatment.

“…The available studies of antegrade endopyelotomy show success rates from 65 to 93%. 19 Outcomes could be improved with careful patient selection. It has been shown that patients with less advanced hydronephrosis (Grade II) have better antegrade endopyelotomy outcomes than more advanced cases do (Grade IV).…”

Laparoscopic Pyeloplasty: Our New Gold Standard

“…In reviews of the surgical management for UPJO, one of the criticisms leveled at laparoscopic pyeloplasty has been the absence of long-term follow up. 3,12 It will certainly be some years before any series of laparoscopic pyeloplasty matches the mean 10-year follow-up demonstrated by O'Reilly and colleagues 1 in their series of open pyeloplasties. Jarrett and coworkers 13 show that failures after laparoscopic pyeloplasty, however, tend to occur within the first year, and Davenport and colleagues 5 showed that the mean time to failure was 4.6 months (range 3-11 mos).…”
