“…Third, the guidewire can easily slide out of the neo-orifice while attempting to pass a ureteral catheter through the wire. At present, few reports have described the retrograde approach of ureteral intubation for transplant kidneys [ 15 ]. Elias Hyams et al reported a retrograde technique for accessing an angle-tipped angiographic catheter.…”

Background Ureteric stricture is a common and salvaging complications after renal transplantation. Two treatment methods are usually used, retrograde ureteral stent placement and percutaneous nephrostomy. The former has a higher failure rate, the latter has a great risk. Therefore, a safe and reliable treatment is needed. Case presentation A technique of retrograde insertion of ureteral stent was established, which was applicable in three transplant recipients with post-transplant ureteral stenosis, and the data was retrospectively recorded. The patients are 2 men and 1 woman, ages 44, 27 and 32 years. These patients underwent a total of five times of retrograde insertion of ureteral stent between 2018 and 2019. None of these patients had any postoperative complication, but all patients had complete recovery from oliguric status within two weeks. Conclusions The retrograde ureteric stent insertion by percutaneous suprapubic access to the bladder (RUS-PSAB) was demonstrated feasibility and safety in a case series with short-term follow-up. However, larger prospective studies are needed.

“…We know that the ureter in kidney transplantation is a source of complications that are potentially fatal [8]. Ureteric obstruction is the most common urologic complication following renal transplantation [9,10]. The reported rate of ureteral obstruction alone is between 1 and 10% [11,12].…”

“…Urological complications and disorders after renal transplantation can be managed with an open surgery, percutaneously, or endoscopically via a retrograde approach. Advances in endourologic techniques and instruments have allowed for less-invasive management of these complications [10]. More specifically, it would decrease patient morbidity; it would decrease the need in subject patients to general anesthesia; it would decrease the rate of graft loss; and it would decrease hospital stay and costs.…”

“…6 In different transplant centers, the incidence of ureteral complications after renal transplants varies from 2% to 20%. [7][8][9] However, there are no relevant data for the pediatric transplant population. We present our experience with the use of the double J stent (DJS) in pediatric renal transplant patients and the infectious complications of this procedure.…”

Objectives: Double J stent placement at kidney transplant may reduce stenosis or leakage complication rates. However, placement may also increase risk for early urinary tract infection (ie, < 3 mo after transplant). In children, the usefulness of double J stent placement is not well defined. Materials and Methods:We analyzed retrospective data from children who received transplants at the Gazi University Transplantation Center and Pediatric Nephrology (Ankara, Turkey) for outcomes related to double J stents. At our center, double J stent placement decision is made by the transplant surgery team during operation. Placements were routinely performed in all transplant recipients. Stent removal occurs within 6 week after transplant. Results: Among 42 transplants since 2006, early urinary tract infection was seen in 7% and stenosis in 3.6% of patients, with no leakage reported. Mean stent removal time was 6 ± 0.5 weeks. Early urinary tract infection was seen in 3 recipients with posterior urethral valve and neurogenic bladder (2 recipients) and meningoma cells and neurogenic bladder (1 recipient). All 3 recipients with early urinary tract infection received clean intermittent catheterization after transplant for adequate emptying of the bladder. In our study group, stent complications such as migration (2 patients) and hematuria (1 patient) were seen, but crusting, breakage, and stone formation were not seen. The 3 patients with urinary tract infection had neurogenic bladder types, complicating the urine outflow system. Stent placement was not a significant risk factor for early urinary tract infection and but had a protective effect. Conclusions:In our study group, we observed no risk factors for routine double J stent placement in pediatric renal transplant procedures. Stent placement was not a risk factor for early urinary tract infection. However, regardless of stent placement, when a recipient had complicated urologic outflow problems, infection became a long-term hurdle.
