The exclusion criteria included ureterocalicostomy (n = 2), simultaneous major surgery (n = 1), drainage using an open-ended ureteral catheter (n = 1), "stentless" pyeloplasty (n = 4), and patients who were lost to follow-up (n = 6).
In the DJ group, one patient had recurrent pain, stones and hydronephrosis, who improved with ureterocalicostomy.
In contrast, one patient in the DJ group with a Clavien III complication had re-stenosis requiring ureterocalicostomy.
Ureterocalicostomy is indicated in case of failure of a previous ureteropyeloplasty, substantial deposition of fibrosis on the UPJ and marked impairment of tissue handling, stenosis of a large segment of proximal ureter and consequent impossibility of achieving a tension-free anastomosis, presence of intrarenal pelvis and other abnormalities.
Following 14 days of the creation of UPJ total obstruction, the animals were subjected to laparoscopic ureterocalicostomy.
On the 28th day post laparoscopic ureterocalicostomy, the swines were subjected to euthanasia for resection of the kidneys and ureters and ascending pyelography.
Bleeding was also negligible in all surgeries during laparoscopic ureterocalicostomy.
A series of trials involving open ureterocalicostomy presented rates of success ranging from 71% (ROSS et al.
In a retrospective study, a series of 11 patients subjected to open ureterocalicostomy were assessed (MATLAGA et al.
Another case which reported success on treatment of hydronephrosis by laparoscopic ureterocalicostomy was published (TERAI et al.
