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.
In our study, blind access was conducted in 8 patients for whom the pelvicaliceal system was not imaged by the injection of the contrast medium through the ureteral catheter
due to impacted stones.
Of these patients, 4 had a double-J stent insertion, 7 a ureteral catheter
insertaion and the remaining 6 were totally tubeless.
8 Fr double-J stent was introduced intracorporeally instead of placing 6 Fr ureteral catheter
1] The most described therapeutic approach is urinary drainage by a nephrostomy and/or a ureteral catheter
with systemic and local antifungal administration.
After reflecting the colon medially, both ipsilateral right duplicated ureters were identified, with distinction between the 2 through the dilatation and the presence of a previously positioned ureteral catheter
in the upper pole ectopic ureter.
Cystoscopy and retrograde ureteral catheter
insertion, posterior subcostal access, one-shot dilation (9Fr dilator, 28F Amplatz dilator), 30F Amplatz working sheath and pneumatic lithotripsy were applied in all operations.
Under general anesthesia and while in the lithotomy position, the patient initially had an open-ended ureteral catheter
placed, through which a guide wire was inserted up to the renal pelvis.
In Group 2, once the stone was visually identified, a 4 Fr ureteral catheter
(Cook Urological Incorporated, Spencer, IN) was advanced through the ureteroscope until it reached beyond the stone; the ureteroscope was reintroduced again into the ureter beside the ureteral catheter
and advanced to the level of the stone.
Therefore, we used a ureteral catheter
to bypass the clots in the bladder.
The ureteral catheters
were removed on the fifth day after the operation.
