Methods like Culp-DeWeerd spiral flap pyeloplasty, Scardino-Prince Vertical Flap, Davis intubated ureterotomy, and ureterocalicostomy
can also be used .
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. Another two patients in the DJ stent group had worsening hydronephrosis, including one case where renal function declined postoperatively from 40% to 10%.
In contrast, one patient in the DJ group with a Clavien III complication had re-stenosis requiring ureterocalicostomy. These complications were also multifactorial and may not have been attributed to the method of stenting alone.
In such cases, the surgeon may consider conversion to the open approach for pyeloplasty or ureterocalicostomy, which has not been widely performed laparoscopically.
Following 14 days of the creation of UPJ total obstruction, the animals were subjected to laparoscopic ureterocalicostomy. A new 3-port laparoscopy was performed avoiding the scars of the first procedure.
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. Bacterial growth assessment was negative in all urine samples.
A series of trials involving open ureterocalicostomy presented rates of success ranging from 71% (ROSS et al., 1990) to 100% (MATLAGA et al., 2005).
In a retrospective study, a series of 11 patients subjected to open ureterocalicostomy were assessed (MATLAGA et al., 2005).
Indication: Robotic-assisted ureterocalicostomy (RAUC) is a potential option in patients with UPJO and significant lower pole caliectasis, patients with failed pyeloplasty and a minimal pelvis, or patients with an exaggerated intrarenal pelvis.
