In our practice, we initially preferred transpelvic transanastomotic catheters, but we recently switched to using the double-J ureteral catheter
The positioning of the fenestrations of the ureteral catheter
was somehow laborious, once it was not easily advanced sometimes, especially nearby the iliac vessels and the ureterovesical junction.
A: 9-mm stone in the renal pelvis; B: ureteral catheter
in the retroperitoneum outside the renal pelvis; C: hydrophilic wire coiled in the retroperitoneum; D: flexible ureteroscope inserted antegradely.
Similar to the open technique, ureteral dissection starts after placing a 6 cm segment of a 5 Fr feeding tube or a 4 Fr open-ended ureteral catheter
and securing it to the ureter with a 4-0 absorbable suture.
If you suspect ureteral injury and have determined that the bladder is intact, you can take either of two approaches to assessing ureteral patency: 1) perform cystoscopy and insert ureteral catheters
in a retrograde manner or 2) incise the dome and insert ureteral catheters
under direct visualization.
A blind access procedure was performed in patients whose pelvicaliceal system was not imaged by injection of the contrast through the ureteral catheter
due to impacted stones.
8 Fr double-J stent was introduced intracorporeally instead of placing 6 Fr ureteral catheter
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).
A ureteral catheter
attached to the Foley catheter is an option if ureteral drainage is not an issue for more than 2 days.
Flexible cystourethroscopy was performed and a 5Fr openended ureteral catheter
was passed up the left transplanted ureteral orifice over a 0.
An ureteral catheter
was placed in the remaining patients and removed on postoperative day 1 with the urethral catheter.
A 5Fr open-ended ureteral catheter
was left through the upper pole tract, which was removed on postoperative day 1.
